    Detroit Auto Show: 2015 GMC Canyon Arrives


    • May We Give You, The 2015 GMC Canyon


    When Chevrolet introduced the 2015 Colorado at the LA Auto Show in November, there was one question we had: Where was the sister truck, the GMC Canyon? Well, GM has answered that question as the Canyon was revealed before the Detroit Auto Show.

    The first thing you notice about the 2015 GMC Canyon is how much it looks like the Sierra and Sierra HD models. This is especially apparent when looking at the front end as the Canyon has the same grille and C-Shaped headlights as its bigger brothers. This really helps set apart the Canyon and Chevrolet Colorado. Also like the Sierra, the Canyon will be available with the All-Terrain package which addsa body colored grille surround, BF Goodrich off-road tires, unique wheels, and revised suspension tuning.

    Moving inside, the Canyon is very similar to the Colorado in its design. A 4.3-inch color screen in the instrument cluster is standard. Optional is a eight-inch touchscreen with GMC's Intellilink. The Canyon will also feature the next-generation of OnStar which will come with 4G LTE and can act as a WiFi hotspot for passengers. The 4G LTE will also allow owners to download apps into their Canyon via GMC AppShop.

    Also new to the Canyon is Teen Driver, a system which allows a parent to set a speed warning or speed limiter, mute the radio till the passengers are belted in, and record such things as speed, fuel economy, and wide-open throttle.

    Engines for the Canyon are much the same as the Colorado. The base is a 2.5L four-cylinder with 193 horsepower and 184 foot-pounds of torque. Optional is the 3.6L V6 with 302 horsepower and 270 pound-feet of torque. The 2.5L will be available with a six-speed manual on the base extended cab/2WD model. Every other model will have a six-speed automatic. Down the line, the 2.8L diesel four-cylinder will become an option.

    The GMC Canyon goes on sale this fall.

    All-New 2015 GMC Canyon Elevates Midsize Truck Segment

    Segment-redefining capabilities, refinement and tech in smart-sized package

    DETROIT – GMC revealed the 2015 Canyon today, an all-new midsize truck that redefines the segment and raises the bar for everything from horsepower and efficiency to quietness and refinement.

    When it goes on sale this year, the all-new Canyon will give GMC one of the only three-truck lineups in the industry. It is expected to deliver class-leading capabilities with the brand's signature refinement – all in an efficiently sized, maneuverable package for customers who want the cargo-hauling and trailering versatility of a truck without the size of a full-size pickup.

    "The all-new 2015 Canyon completes GMC's three-truck family, which started with the redesigned 2014 Sierra 1500 and 2015 Sierra HD," said Tony DiSalle, vice president of GMC Marketing. "It rounds out a lineup that offers the broadest range of capabilities in the industry, giving truck customers more choices to find the vehicle that meets their professional, personal and lifestyle needs."

    Based on a proven global architecture and engineered for the unique demands and driving conditions of North American drivers, the new Canyon is expected to deliver:

    • The segment's best horsepower – an estimated 193 horsepower (146 kW) from a standard 2.5L I-4 and an estimated 302 horsepower (224 kW) from an available 3.6L V-6
    • The segment's best payload of at least 1,450 pounds (657 kg)
    • The segment's best maximum trailering rating (when properly equipped) of at least 6,700 pounds (3,039 kg)
    • Even greater capability with a powerful and efficient Duramax 2.8L turbodiesel engine coming in 2016

    "Not everyone needs full-size capability, but they still deserve strength and true-truck attributes that come in larger models. The Canyon will offer all the capability with confidence – and GMC's signature refinement that complements active lifestyles," said DiSalle. "It also delivers the technology customers want with more standard features."

    Canyon's customer-focused technologies include available OnStar 4G LTE connectivity with a built-in Wi-Fi hotspot and expected segment-first available driver alert features such as forward collision alert, lane departure warning and a standard rear-vision camera.

    Additionally, RemoteLink Key Fob Services allow owners to lock and unlock their vehicle, flash the lights and honk the horn, and, on equipped models, even remotely start the engine using the RemoteLink smartphone app. The service is free for five years. Additional OnStar services and data plans will be available with a paid subscription.

    GMC's ProGrade protection program for two years/24,000 miles – whichever comes first – of scheduled maintenance, is standard and covers four oil changes, tire rotations and 27-point inspections. It complements the three-year/36,000-mile – whichever comes first – bumper-to-bumper limited vehicle warranty and five-year/100,000-mile – whichever comes first – powertrain limited warranty.

    Designed for capability, comfort and refinement

    Inside and out, the 2015 Canyon is pure GMC, with a quiet, refined interior distinguished by premium materials and a commanding exterior presence that emulates the technology-infused design aesthetic introduced on the 2014 Sierra 1500 and 2015 Sierra HD models.

    Bold front-end styling incorporates the segment's only standard projector beam headlamps and GMC's signature C-shaped LED daytime running lamps on all models. Three body configurations are offered: An extended cab model with a six-foot bed, a crew cab with a five-foot bed and a crew cab with a six-foot bed. With the tailgate down, the six-foot bed allows eight-foot-long items to be hauled within the vehicle.

    Canyon is offered in base, SLE and SLT models, in 2WD and 4WD models, and with an aggressively styled All-Terrain package offered on SLE models. It includes 17-inch painted aluminum wheels covered by all-terrain tires, a body-color grille surround with horizontal chrome bars and specific suspension tuning.

    From a refinement standpoint, the Canyon features triple-sealed doors inlaid in the body sides, like the 2014 Sierra, for improved aerodynamic performance and a quieter interior. And to help keep overall mass down and improve the front-to-rear weight balance, the Canyon features an all-new aluminum hood.

    It also features the segment's only active aero grille shutters, which close at certain highway speeds to enhance efficiency through improved aerodynamics.

    Additional exterior features include:

    • Segment-first CornerStep rear bumper design, pioneered on the 2014 Sierra, is standard
    • Available segment-first EZ Lift-and-Lower locking tailgate that uses an internal torsion bar to make raising the tailgate easier with one hand, and a damper for more-controlled lowering
    • Standard two-tier loading that allows a platform to effectively split the bed into upper and lower sections, making it easier to haul, store and conceal items such as tools
    • Thirteen reconfigurable and four stationary tie-down locations throughout the bed for use with available, removable cargo tie-down rings
    • Standard bed rail and tailgate protectors
    • Available factory-installed spray-in bed liner
    • Range of 16-, 17- and 18-inch aluminum wheels

    A diverse collection of work- and lifestyle-supporting accessories will be offered including everything from a bed liner and innovative cargo management system to a custom tonneau cover, removable cargo rings, tool box and more.

    Comfortable and connected cabin

    The interior of the 2015 Canyon is designed to be comfortable, heavily equipped and well connected. A bold, upright instrument panel with large instruments and a central driver information center is similar to Sierra. A center console-mounted shifter is similar to those found in midsize cars and crossovers.

    The Canyon's cabin boasts exceptional attention to detail and premium appointments, including a sculpted headliner that enhances headroom, halo lighting on key controls for easier viewing and an open area at the front of the center console for easier phone charging.

    Additional interior details include:

    • Sculpted door panels that make it easier to enter and exit the vehicle
    • Upper-instrument panel storage bin – when not equipped with the uplevel audio system – and large glove box volume
    • Standard center console with room to store a tablet
    • Rear under-seat storage

    Canyon's seats are designed for long-haul comfort and wear, too. They use dual-firmness foam for greater comfort on long drives and high-wear, stain-resistant cloth seating trim. A power-adjustable driver's seat is standard, and heated leather seats are standard on SLT. The All-Terrain package features exclusive color and trim details, including embossed seatbacks and unique contrast stitching.

    Comfort is enhanced with technologies, connectivity and other features that support owners' daily and recreational lives including a standard 4.2-inch-diagonal color driver information screen in the instrument cluster

    Also available:

    • Eight-inch-diagonal color touch screen and multiple USB ports
    • OnStar 4G LTE with built-in Wi-Fi hot spot
    • Next-generation OnStar and IntelliLink enhancements with gesture recognition and natural language voice recognition
    • Siri Eyes Free Mode for iPhone users
    • Teen Driver feature
    • GMC AppShop
    • Navigation

    Teen Driver is a new, configurable IntelliLink feature that allows parents to set a radio volume limit, establish a speed warning set between 40 and 70 mph, and set a speed limiter. It also automatically mutes the radio when the driver or front passenger safety belt is not fastened and a "report card" that records mileage, wide-open throttle events, ABS events, maximum speed and other data. The custom features are locked by a PIN, which is set by the parent.

    Canyon models with an eight-inch IntelliLink screen will also feature a new in-car app marketplace: GMC AppShop. It allows customers to download apps directly to their IntelliLink system and organize, update or delete them throughout the life of the vehicle. Available apps will connect drivers to music, news, weather, travel information, vehicle data and more.

    Segment-best power and efficiency

    GMC expects Canyon to be the most powerful and efficient truck in the segment, allowing owners to haul and tow more while being efficient. A 2.5L I-4 is standard, and a 3.6L V-6 is available. They are based on award-winning engine families and tuned to deliver the low-rpm torque customers depend on for hauling and towing.

    The 2.5L four is estimated at 193 horsepower (146 kW) and 184 lb-ft of torque (253 Nm), with approximately 90 percent of the peak torque available from 2,000 rpm to 6,200 rpm. The 3.6L engine is estimated at 302 horsepower (224 kW) and 270 lb-ft of torque (366 Nm). SAE certification of the power ratings is pending.

    Both engines feature direct injection and variable valve timing to make the most of power and efficiency. An aluminum block, forged-steel crankshaft, dual-overhead camshafts and jet-spray piston cooling are featured on both engines. The 2.5L incorporates a two-stage variable-displacement oil pump, for greater efficiency, as well as a balance shaft located in the oil pan, for greater refinement.

    All models are matched with a six-speed automatic transmission that complements the truck-tuned engines with features that make hauling and trailering easier and more comfortable, including auto grade braking and a tow/haul mode. A six-speed manual transmission is also available with the 2.5L engine in base extended cab/2WD models.

    Class-leading capabilities and superior ride quality

    The Canyon delivers the capability expected of a GMC truck, including expected segment-leading payload and trailering. Like the full-size Sierra, Canyon is built on a fully boxed perimeter frame, which provides the strength to support its capabilities, and a ride expected to be smooth and quiet.

    A coil-over-type front suspension features aluminum knuckles that are low in mass and high in strength contributing to a more responsive, immediate feel to driver inputs, as well as efficiency. The 2015 Canyon also features the segment's first application of electric power steering, which enhances efficiency because it is not driven by the engine.

    Additionally, the Canyon has a tight turning radius of only about 41 feet (12.6 meters), making it easier to maneuver when parking or backing into tight spots, such as garages or campsites.

    Four-wheel disc brakes, with four-piston front calipers, are standard and feature segment-exclusive Duralife™ brake rotors – also pioneered on the 2014 Sierra. They can offer up to double the service life, which can help lower ownership costs.

    Canyon is available with an automatic locking rear differential known by its G80 option code. Introduced by General Motors more than 40 years ago, it gives drivers a traction advantage when needed and everyday comfort when it's not. It is available on SLE and SLT, and standard with the All-Terrain package.

    AutoTrac automatic four-wheel drive is also a segment-first feature, which employs an electronically controlled transfer case that allows the driver to shift from 2WD to 4WD. The driver can select four modes, 2WD, Auto, 4WD HI, or 4WD Lo. By selecting 'Auto' mode, the transfer case will operate in 2WD and will automatically apply traction to the front wheels (4WD) when the vehicle senses wheel slippage.

    Safety features

    With 360 degrees of available active and passive safety technologies, Canyon is designed to help keep occupants safe on the road, with standard features including:

    • Six air bags, including head curtain side air bags that can also reduce the risk of occupant ejection
    • Large rearview mirrors and rear-vision camera system for greater visibility
    • StabiliTrak stability control system with rollover mitigation technology, trailer sway control, hill start assist and hill descent control (All Terrain).

    Available safety features include:

    • Segment-first forward collision alert
    • Segment-first lane departure warning

    The Canyon will be assembled at GM's Wentzville, Mo., assembly plant. GMC will continue to work on and develop the Canyon until the start of production in fall 2014. The content of this release is based on current GM testing and is subject to change.

    My next new vehicle, hopefully this year. I really want a Sierra 2500 HD crew cab, but that's just wishful thinking (with the recent price increases made to the 1500's, I know the 2500's will be priced sky high too). Plus I have to consider fuel economy along with the monthly payment and insurance costs, so that makes the Canyon a near-perfect solution. Just need to make sure the family will be comfortable in this for the next several years (growing family - 3 & 8 year olds).

    Anyone with a serious contact at GM - please pass the word on for me that I want a DARK BLUE exterior color offered on the Canyon. No electric/bright blue for this "truck guy". My 2001 GMC Sonoma Highrider was ordered in Indigo Blue Metallic, I'd love to get my new Canyon in a similar shade of dark/navy blue too.

    I dig that all black All Terrain model I've seen in other press shots.

    Honestly, you can't go wrong with either truck. The Colorado is handsome. The Canyon is handsome. This is the first time in a long time that you can say that Chevy's pickup looks just as good as GMC's and vice versa.

    I'll add, though, that my tastes are very partial to that Canyon All Terrain version I mentioned, but my wallet would probably vote Colorado.

    I gotta say I am a little disappointed. It is a nice looking truck, but I guess I was expecting something other than a 7/8 scale Sierra.

    Ain't that cute, a baby Sierra. They were really going for the family look with this one. Medium, large, or extra-large; What will it be today, Sir? Mmmm, I feel like being reasonable today... and I'm sort of on a diet. Canyon, it is.

    On a serious note, the Canyon looks great. It's sthuper classthy, and delivers a healthy addition of luxury over the Colorado. Very well executed duo, to say the least. Personally speaking, I like the dynamism of the Colorado more. It's more lively and youthful. It's refreshingly unique from the rest of Chevrolet's truck lineup.

    While unsurprisingly not all that different from the Canyon save the front end and wheel arches, it is nonetheless a handsome truck and wears the Sierra face well. I think GM did a very good job with the designs of these trucks.

    Too bad, was really hoping they would put the 4.3L LV3 in the Canyon to differentiate it from the Colorado. Still do not understand the choice of the LFX. With the tune it is running it appears to have nearly identical numbers to the Pentastar V6 in the Ram pickups. That pentastar is still port injected.

    I hope a brown and tan interior is available on the Chevy, too.

    I spoke to the GM people and the answer is no, you'll have a choice of Black, or Black and gray in the Colorado. They are specifically reserving the other colors and higher end materials for the GMC.

    That's a shame, because I for one want the black and gray colored interior in my new Canyon, and I'm sure some Colorado buyers would want the brown and tan interior in theirs. Makes no sense to restrict color selection to one brand over another - especially since they're made in the same plant!! I can understand about the trim pieces, when you're trying to establish a luxury feel for one brand over another. So far the only exterior colors not shared between the two are the Lazer Blue (wish list item:I want a dark blue color added to the Canyon's pallette) and Yellow (which just doesn't go along with the more upscale approach being sought by GMC).

    On the GMC website, only the black and brown/tan interior is listed as the available color options. I took your statement to verify that the website was correct in what it shows.

    I'm most definitely interested in the Canyon, but don't like the all-season tires on the Bronze colored SLT Crew Cab model shown. The All Terrain model is wearing the BF Goodrich all-terrain tires that I'm more interested in:

    2015GMCCanyonSLE-AllTerrainNAIASdebut_zp

    I do hope that there is an option for these tires on the SLT model. Otherwise, this would be a big change needed before I drove off the dealer's lot with my new Canyon ;)

    That gray Canyon above looks good. I like the "galvanized" Chevy Z71 interior color that is shown on the website, but it wouldn't go with the Rainforest Green too well, imo. Although I do like the Cyber Gray...

      Over the weekend, General Motors published and then deleted the power figures for the new 6.6L Duramax Diesel V8 that would be appearing in the 2017 Chevrolet Silverado HD and GMC Sierra HD. Today at the Texas State Fair, GM revealed everything about this new engine.
      We'll begin with the most important detail, power output. The numbers that GM revealed match the numbers posted to their powertrain site - 445 horsepower and 910 pound-feet of torque. Compared to the current Duramax V8, the new engine produces 48 more horsepower and 145 more pound-feet of torque.
      How was GM able to pull this off? They basically went through the engine with a fine tooth comb and made various changes. GM says 90 percent of this engine has been changed. Some of the changes include new electronically controlled, variable-vane turbocharger, revised cylinder heads, improved cooling, and revised fuel delivery system. The updated Duramax can also run B20 bio-diesel.
      Figures for payload and towing will be announced at a later date.

      DALLAS — Chevrolet today announced the redesigned Duramax 6.6L V-8 turbo-diesel offered on the 2017 Silverado HD. This next-generation redesign offers more horsepower and torque than ever — an SAE-certified 445 horsepower (332 kW) and 910 lb.-ft. (1,234 Nm) — to enable easier, more confident hauling and trailering.
      Along with a 19 percent increase in max torque over the current Duramax 6.6L, the redesigned turbo-diesel’s performance is quieter and smoother, for greater refinement. In fact, engine noise at idle is reduced 38 percent.
      “With nearly 2 million sold over the past 15 years, customers have forged a bond with the Duramax diesel based on trust and capability,” said Dan Nicholson, vice president, Global Propulsion Systems. “The new Duramax takes those traits to higher levels.”
      The new Duramax 6.6L shares essentially only the bore and stroke dimensions of the current engine and incorporates a new, GM-developed control system. The Duramax’s signature low-rpm torque production hasn’t changed and still offers 90 percent of peak torque at a low 1,550 rpm and sustains it through 2,850 rpm.
      “Nearly everything about the Duramax is new, designed to produce more torque at lower rpm and more confidence when trailering or hauling,” said Gary Arvan, chief engineer. “You’ll also notice the refinement improvements the moment you start the engine, and appreciate them as you cruise quietly down the highway — with or without a trailer.”
      Additional highlights include:
      New, stronger cylinder block and cylinder heads New, stronger rotating and reciprocating assembly Increased oil- and coolant-flow capacity New EGR system with single cooler and integrated bypass New electrically actuated/electronically controlled turbocharging system All-new advanced solenoid fuel system All-new electronic controls New full-length damped steel oil pan that contributes to quietness New rocker cover/fuel system acoustical treatments B20 bio-diesel compatibility SAE-certified 445 net horsepower (332 kW) at 2,800 rpm SAE-certified 910 net lb.-ft. of torque (1,234 Nm) at 1,600 rpm A new, patent-pending vehicle air intake system — distinguished on the Silverado HD by a bold hood scoop — drives cool, dry air into the engine for sustained performance and cooler engine temperatures during difficult conditions, such as trailering on steep grades. Cooler air helps the engine run better under load, especially in conditions where engine and transmission temperatures can rise quickly. That allows the Duramax to maintain more power and vehicle speed when trailering in the toughest conditions.
      The intake design is another example of the advanced integration included in the 2017 Silverado HD that makes it over-the-road capable.   
      A strong foundation
      As with previous versions, the new Duramax block features a strong cast-iron foundation known for its durability, with induction-hardened cylinder walls and five nodular iron main bearings. It retains the same 4.05-inch (103mm) and 3.89-inch (99mm) bore and stroke dimensions as the current engine, retaining the Duramax’s familiar 6.6L (403 cu.-in./6,599 cc) displacement.
      A deep-skirt design and four-bolt, cross-bolted main caps help ensure the block’s strength and enable more accurate location of the rotating assembly. A die-cast aluminum lower crankcase also strengthens the engine block and serves as the lower engine cover, while reducing its overall weight.
      The new engine block incorporates larger-diameter crankshaft connecting rod journals than the current engine, enabling the placement of a stronger crankshaft and increased bearing area to handle higher cylinder loads.
      An enhanced oiling circuit, with higher flow capacity and a dedicated feed for the turbocharger, provides increased pressure at the turbo and faster oil delivery. Larger piston-cooling oil jets at the bottom of the cylinder bores spray up to twice the amount of engine oil into oil galleries under the crown of the pistons, contributing to lower engine temperature and greater durability.
      A new, two-piece oil pan contributes to the new Duramax’s quieter operation. It consists of a laminated steel oil pan with an upper aluminum section. The aluminum section provides strength-enhancing rigidity for the engine, but a pan made entirely of aluminum would radiate more noise, so the laminated steel lower section is added to dampen noise and vibration.
      There’s also an integrated oil cooler with 50 percent greater capacity than the current engine’s, ensuring more consistent temperatures at higher engine loads.
      Segment firsts
      Re-melt piston bowl rim Venturi Jet Drain Oil Separator Closed-loop glow plug temperature control Stronger pistons with remelt
      A tough, forged micro-alloy steel crankshaft anchors the new Duramax’s stronger rotating assembly. Cut-then-rolled journal fillets contribute to its durability by strengthening the junction where the journals — the round sections on which the bearings slide — meet the webs that separate the main and rod journals.
      The connecting rods are stronger, too, and incorporate a new 45-degree split-angle design to allow the larger-diameter rod bearings to pass through the cylinder bores during engine assembly. They’re forged and sintered with a durable powdered metal alloy, with a fractured-cap design enabling more precise cap-to-rod fitment. 
      A new, stronger cast-aluminum piston design tops off the rotating assembly. It features a taller crown area and a remelted combustion bowl rim for greater strength. Remelting is an additional manufacturing process for aluminum pistons in which the bowl rim area is reheated after casting and pre-machining, creating a much finer and more consistent metal grain structure that greatly enhances thermal fatigue properties.
      Additionally, the Duramax’s pistons don’t use pin bushings, reducing reciprocating weight to help the engine rev quicker and respond faster to throttle changes.
      Lightweight cylinder heads, solenoid injectors
      The redesigned engine retains the Duramax’s signature first-in-class aluminum cylinder head design, with six head bolts per cylinder and four valves per cylinder. The aluminum construction helps reduce the engine’s overall weight, while the six-bolt design provides exceptional head-clamping strength — a must in a high-compression, turbocharged application.
      A new aluminum head casting uses a new double-layer water core design that separates and arranges water cores in layers to create a stiffer head structure with more precise coolant flow control. The heads’ airflow passages are also heavily revised to enhance airflow, contributing to the engine’s increased horsepower and torque.
      The Duramax employs a common-rail direct injection fuel system with new high-capability solenoid-type injectors. High fuel pressure of 29,000 psi (2,000 bar) promotes excellent fuel atomization for a cleaner burn that promotes reduced particulate emissions. The new injectors also support up to seven fuel delivery events per combustion event, contributing to lower noise, greater efficiency and lower emissions. Technology advancements enable less-complex solenoid injectors to deliver comparable performance to piezo-type injectors.
      Electronically controlled, variable-geometry turbocharging system
      A new electronically controlled, variable-vane turbocharger advances the Duramax’s legacy of variable-geometry boosting. Compared to the current engine, the system produces higher maximum boost pressure — 28 psi (195 kPa) — to help the engine make more power, and revisions to enhance the capability of the exhaust-brake system.
      Along with a new camshaft profile and improved cylinder head design, the Duramax’s new variable-vane turbocharger enables the engine to deliver more power with lower exhaust emissions. It uses a more advanced variable-vane mechanism, allowing a 104-degree F (40 C) increase in exhaust temperature capability. The self-contained mechanism decouples movement from the turbine housing, allowing operation at higher temperature. That enables the engine to achieve higher power at lower cylinder pressure. Additionally, it has lower internal leakage, allowing more exhaust energy to be captured during exhaust braking.
      The integrated exhaust brake system makes towing less stressful by creating added backpressure in the exhaust, resulting in negative torque during deceleration and downhill driving, enhancing driver control and prolonging brake pad life.
      Venturi Jet Drain Oil Separator
      A new Venturi Jet Drain Oil Separator employed with the Duramax 6.6L is the first of its type in the segment and is designed to ensure oil control in sustained full-load operation. The totally sealed system collects the fine mist of oil entrained in the blow-by gas and uses a small portion of the boosted air generated by the turbocharger to pump the collected oil back to the engine oil sump for re-use by the engine. Less sophisticated systems are not able to return this oil during full-load operation, which can result in oil carryover into the cylinders during combustion.
      Cold Start System
      The new Duramax also provides outstanding cold-weather performance, with microprocessor-controlled glow plugs capable of gas-engine-like starting performance in fewer than 3 seconds in temperatures as low as -20 degrees F (-29 C) without a block heater. The system is enhanced with ceramic glow plugs and automatic temperature compensation — a first-in-class feature providing improved robustness and capability. The automatic temperature compensation assesses and adjusts the current to each glow plug for every use, providing optimal temperature for cold start performance and durability.     
      Electronic throttle valve and cooled EGR
      Unlike a gasoline engine, a diesel engine doesn’t necessarily require a throttle control system. The Duramax 6.6L employs an electronic throttle valve to regulate intake manifold pressure in order to increase exhaust gas recirculation (EGR) rates. It also contributes to smoother engine shutdown.
      Additionally, a cooled exhaust gas recirculation (EGR) system enhances performance and helps reduce emissions by diverting some of the engine-out exhaust gas and mixing it back into the fresh intake air stream, which is fed through the cylinder head for combustion. This lowers combustion temperatures, improving emissions performance by reducing NOx formation.
      The exhaust is cooled in a unique heat exchanger before it’s fed into the intake stream through a patented EGR mixing device, further improving emissions and performance capability. An integrated bypass allows non-cooled exhaust gas to be fed back into the system to help the engine more quickly achieve optimal operating temperature when cold.
      B20 Biodiesel Capability
      The new Duramax 6.6L is capable of running on B20 biodiesel, a fuel composed of 20 percent biodiesel and 80 percent conventional diesel. B20 helps lower carbon dioxide emissions and lessens dependence on petroleum. It is a domestically produced, renewable fuel made primarily of plant matter — mostly soybean oil.
      Manufacturing
      The new Duramax 6.6L turbo-diesel engine is produced with locally and globally sourced parts at the DMAX Ltd. (GM’s joint venture with Isuzu) manufacturing facility in Moraine, Ohio.

      Over the weekend, General Motors published and then deleted the power figures for the new 6.6L Duramax Diesel V8 that would be appearing in the 2017 Chevrolet Silverado HD and GMC Sierra HD. Today at the Texas State Fair, GM revealed everything about this new engine.
      We'll begin with the most important detail, power output. The numbers that GM revealed match the numbers posted to their powertrain site - 445 horsepower and 910 pound-feet of torque. Compared to the current Duramax V8, the new engine produces 48 more horsepower and 145 more pound-feet of torque.
      How was GM able to pull this off? They basically went through the engine with a fine tooth comb and made various changes. GM says 90 percent of this engine has been changed. Some of the changes include new electronically controlled, variable-vane turbocharger, revised cylinder heads, improved cooling, and revised fuel delivery system. The updated Duramax can also run B20 bio-diesel.
      Figures for payload and towing will be announced at a later date.

      DALLAS — Chevrolet today announced the redesigned Duramax 6.6L V-8 turbo-diesel offered on the 2017 Silverado HD. This next-generation redesign offers more horsepower and torque than ever — an SAE-certified 445 horsepower (332 kW) and 910 lb.-ft. (1,234 Nm) — to enable easier, more confident hauling and trailering.
      Along with a 19 percent increase in max torque over the current Duramax 6.6L, the redesigned turbo-diesel’s performance is quieter and smoother, for greater refinement. In fact, engine noise at idle is reduced 38 percent.
      “With nearly 2 million sold over the past 15 years, customers have forged a bond with the Duramax diesel based on trust and capability,” said Dan Nicholson, vice president, Global Propulsion Systems. “The new Duramax takes those traits to higher levels.”
      The new Duramax 6.6L shares essentially only the bore and stroke dimensions of the current engine and incorporates a new, GM-developed control system. The Duramax’s signature low-rpm torque production hasn’t changed and still offers 90 percent of peak torque at a low 1,550 rpm and sustains it through 2,850 rpm.
      “Nearly everything about the Duramax is new, designed to produce more torque at lower rpm and more confidence when trailering or hauling,” said Gary Arvan, chief engineer. “You’ll also notice the refinement improvements the moment you start the engine, and appreciate them as you cruise quietly down the highway — with or without a trailer.”
      Additional highlights include:
      New, stronger cylinder block and cylinder heads New, stronger rotating and reciprocating assembly Increased oil- and coolant-flow capacity New EGR system with single cooler and integrated bypass New electrically actuated/electronically controlled turbocharging system All-new advanced solenoid fuel system All-new electronic controls New full-length damped steel oil pan that contributes to quietness New rocker cover/fuel system acoustical treatments B20 bio-diesel compatibility SAE-certified 445 net horsepower (332 kW) at 2,800 rpm SAE-certified 910 net lb.-ft. of torque (1,234 Nm) at 1,600 rpm A new, patent-pending vehicle air intake system — distinguished on the Silverado HD by a bold hood scoop — drives cool, dry air into the engine for sustained performance and cooler engine temperatures during difficult conditions, such as trailering on steep grades. Cooler air helps the engine run better under load, especially in conditions where engine and transmission temperatures can rise quickly. That allows the Duramax to maintain more power and vehicle speed when trailering in the toughest conditions.
      The intake design is another example of the advanced integration included in the 2017 Silverado HD that makes it over-the-road capable.   
      A strong foundation
      As with previous versions, the new Duramax block features a strong cast-iron foundation known for its durability, with induction-hardened cylinder walls and five nodular iron main bearings. It retains the same 4.05-inch (103mm) and 3.89-inch (99mm) bore and stroke dimensions as the current engine, retaining the Duramax’s familiar 6.6L (403 cu.-in./6,599 cc) displacement.
      A deep-skirt design and four-bolt, cross-bolted main caps help ensure the block’s strength and enable more accurate location of the rotating assembly. A die-cast aluminum lower crankcase also strengthens the engine block and serves as the lower engine cover, while reducing its overall weight.
      The new engine block incorporates larger-diameter crankshaft connecting rod journals than the current engine, enabling the placement of a stronger crankshaft and increased bearing area to handle higher cylinder loads.
      An enhanced oiling circuit, with higher flow capacity and a dedicated feed for the turbocharger, provides increased pressure at the turbo and faster oil delivery. Larger piston-cooling oil jets at the bottom of the cylinder bores spray up to twice the amount of engine oil into oil galleries under the crown of the pistons, contributing to lower engine temperature and greater durability.
      A new, two-piece oil pan contributes to the new Duramax’s quieter operation. It consists of a laminated steel oil pan with an upper aluminum section. The aluminum section provides strength-enhancing rigidity for the engine, but a pan made entirely of aluminum would radiate more noise, so the laminated steel lower section is added to dampen noise and vibration.
      There’s also an integrated oil cooler with 50 percent greater capacity than the current engine’s, ensuring more consistent temperatures at higher engine loads.
      Segment firsts
      Re-melt piston bowl rim Venturi Jet Drain Oil Separator Closed-loop glow plug temperature control Stronger pistons with remelt
      A tough, forged micro-alloy steel crankshaft anchors the new Duramax’s stronger rotating assembly. Cut-then-rolled journal fillets contribute to its durability by strengthening the junction where the journals — the round sections on which the bearings slide — meet the webs that separate the main and rod journals.
      The connecting rods are stronger, too, and incorporate a new 45-degree split-angle design to allow the larger-diameter rod bearings to pass through the cylinder bores during engine assembly. They’re forged and sintered with a durable powdered metal alloy, with a fractured-cap design enabling more precise cap-to-rod fitment. 
      A new, stronger cast-aluminum piston design tops off the rotating assembly. It features a taller crown area and a remelted combustion bowl rim for greater strength. Remelting is an additional manufacturing process for aluminum pistons in which the bowl rim area is reheated after casting and pre-machining, creating a much finer and more consistent metal grain structure that greatly enhances thermal fatigue properties.
      Additionally, the Duramax’s pistons don’t use pin bushings, reducing reciprocating weight to help the engine rev quicker and respond faster to throttle changes.
      Lightweight cylinder heads, solenoid injectors
      The redesigned engine retains the Duramax’s signature first-in-class aluminum cylinder head design, with six head bolts per cylinder and four valves per cylinder. The aluminum construction helps reduce the engine’s overall weight, while the six-bolt design provides exceptional head-clamping strength — a must in a high-compression, turbocharged application.
      A new aluminum head casting uses a new double-layer water core design that separates and arranges water cores in layers to create a stiffer head structure with more precise coolant flow control. The heads’ airflow passages are also heavily revised to enhance airflow, contributing to the engine’s increased horsepower and torque.
      The Duramax employs a common-rail direct injection fuel system with new high-capability solenoid-type injectors. High fuel pressure of 29,000 psi (2,000 bar) promotes excellent fuel atomization for a cleaner burn that promotes reduced particulate emissions. The new injectors also support up to seven fuel delivery events per combustion event, contributing to lower noise, greater efficiency and lower emissions. Technology advancements enable less-complex solenoid injectors to deliver comparable performance to piezo-type injectors.
      Electronically controlled, variable-geometry turbocharging system
      A new electronically controlled, variable-vane turbocharger advances the Duramax’s legacy of variable-geometry boosting. Compared to the current engine, the system produces higher maximum boost pressure — 28 psi (195 kPa) — to help the engine make more power, and revisions to enhance the capability of the exhaust-brake system.
      Along with a new camshaft profile and improved cylinder head design, the Duramax’s new variable-vane turbocharger enables the engine to deliver more power with lower exhaust emissions. It uses a more advanced variable-vane mechanism, allowing a 104-degree F (40 C) increase in exhaust temperature capability. The self-contained mechanism decouples movement from the turbine housing, allowing operation at higher temperature. That enables the engine to achieve higher power at lower cylinder pressure. Additionally, it has lower internal leakage, allowing more exhaust energy to be captured during exhaust braking.
      The integrated exhaust brake system makes towing less stressful by creating added backpressure in the exhaust, resulting in negative torque during deceleration and downhill driving, enhancing driver control and prolonging brake pad life.
      Venturi Jet Drain Oil Separator
      A new Venturi Jet Drain Oil Separator employed with the Duramax 6.6L is the first of its type in the segment and is designed to ensure oil control in sustained full-load operation. The totally sealed system collects the fine mist of oil entrained in the blow-by gas and uses a small portion of the boosted air generated by the turbocharger to pump the collected oil back to the engine oil sump for re-use by the engine. Less sophisticated systems are not able to return this oil during full-load operation, which can result in oil carryover into the cylinders during combustion.
      Cold Start System
      The new Duramax also provides outstanding cold-weather performance, with microprocessor-controlled glow plugs capable of gas-engine-like starting performance in fewer than 3 seconds in temperatures as low as -20 degrees F (-29 C) without a block heater. The system is enhanced with ceramic glow plugs and automatic temperature compensation — a first-in-class feature providing improved robustness and capability. The automatic temperature compensation assesses and adjusts the current to each glow plug for every use, providing optimal temperature for cold start performance and durability.     
      Electronic throttle valve and cooled EGR
      Unlike a gasoline engine, a diesel engine doesn’t necessarily require a throttle control system. The Duramax 6.6L employs an electronic throttle valve to regulate intake manifold pressure in order to increase exhaust gas recirculation (EGR) rates. It also contributes to smoother engine shutdown.
      Additionally, a cooled exhaust gas recirculation (EGR) system enhances performance and helps reduce emissions by diverting some of the engine-out exhaust gas and mixing it back into the fresh intake air stream, which is fed through the cylinder head for combustion. This lowers combustion temperatures, improving emissions performance by reducing NOx formation.
      The exhaust is cooled in a unique heat exchanger before it’s fed into the intake stream through a patented EGR mixing device, further improving emissions and performance capability. An integrated bypass allows non-cooled exhaust gas to be fed back into the system to help the engine more quickly achieve optimal operating temperature when cold.
      B20 Biodiesel Capability
      The new Duramax 6.6L is capable of running on B20 biodiesel, a fuel composed of 20 percent biodiesel and 80 percent conventional diesel. B20 helps lower carbon dioxide emissions and lessens dependence on petroleum. It is a domestically produced, renewable fuel made primarily of plant matter — mostly soybean oil.
      Manufacturing
      The new Duramax 6.6L turbo-diesel engine is produced with locally and globally sourced parts at the DMAX Ltd. (GM’s joint venture with Isuzu) manufacturing facility in Moraine, Ohio.
      Allison 1000 Automatic Transmission
      The proven Allison 1000 six-speed automatic transmission is matched with the new Duramax 6.6L. A number of refinements have been made to accommodate the engine’s higher torque capacity, including a new torque converter.
      The Allison 1000’s technologically advanced control features, such as driver shift control with manual shift feature and a patented elevated idle mode cab warm-up feature, haven’t changed.

      The seemingly never-ending diesel heavy-duty truck war is back in force with Ford announcing the power figures for the F-Series Super Duty back in the summer. We were wondering when either FCA or GM would strike back. Well GM did this over the weekend by accidently and then subsequently deleting the figures for the next-generation Duramax V8 diesel.
      Truck Trend got screenshots of GM Powertrain's website where the details of the L5P 6.6L Duramax turbodiesel are there to see: 445 horsepower and 910 pound-feet of torque. Compared the 6.7L PowerStoke V8 found in the 2017 F-Series Super Duty, the updated Duramax produces 5 more horsepower but is slight behind in torque (15 down from the PowerStroke's 925 pound-feet).
      We know for sure that the new Duramax will debut a new air intake system (you can see the new hood scoop in the picture above). More air is a good thing as it means better cooling and more power.
      The Texas State Fair is this week and it has become a showplace for the various truck manufacturers to make big announcements. We wouldn't be shocked if General Motors debuts the new Duramax there.
