  1. No one was quite sure what would happen to Holden Special Vehicles (HSV) after the end of the RWD Commodore. Rumors abounded from a modified Colorado to the importation of the Camaro. We finally have some concrete answers. Today in Australia, Holden and HSV made a joint announcement of a new agreement between the two companies. HSV will now use their engineering talents that created some mad Holdens into expanding Holden's range to new levels, along with importing various GM products. “This marks a whole new era for HSV and Holden and I hope our customers are as excited as we are. HSV is moving beyond simply ‘hotting up’ existing models, and customers will see two product streams from HSV over the next few years. This is ‘Game-On’ in a very big way,” said Tim Jackson, HSV's managing director in a statement. Colorado SportsCat by HSV The first product of this new era for HSV is the Colorado SportsCat. Taking a Z71 Colorado, HSV adds a strut brace, enlarged anti-roll bar, taller and stiffer springs, new dampers, and forged alloy 18-inch wheels wrapped in off-road rubber. The exterior is more aggressive with a front skid plate, new grille design, alloy sports bar, and tonneau cover. Stepping things up is the SportsCat+ that includes an AP Racing brake package, an electro-hydraulic anti-roll bar that can disconnect to improve wheel articulation, and a more aggressive exterior. You may have noticed that we haven't mentioned anything about the powertrain. That's because HSV didn't make any changes to the 2.8L Duramax turbodiesel. It will still produce the same 147kW and 500Nm (around 197 horsepower and 369 pound-feet of torque). “The cost/complexity for a relatively minor power increase didn’t make sense. We did a fair bit of consumer research. For our traditional customers, it was power, power, power, but for dual-cabs it was about the overall package," said Jackson to CarAdvice when asked about why there was no power upgrade. “If this were a Commodore product, I would be concerned about not offering extra power. We thought dynamics was an area we could improve. And I think we’ll have the benchmark in on-road driving [in the light-commercial segment].” The SportsCar goes on sale in February. Chevrolet Camaro and Silverado HD to be Imported and Converted to RHD There have been a number of rumors about the Camaro coming to Australia for the past year so. GM kept their mouth shut whenever asked about it. But the Camaro will be arriving in Australia come next July. HSV will convert the Camaro to right hand drive. The Australian Camaro will be the 2SS featuring the 6.2L V8 and eight-speed automatic. HSV is hoping offer a six-speed manual version sometime later. Standard equipment includes adaptive dampers, Brembo brakes, 20-inch alloy wheels, keyless entry, heated and ventilated seats with power adjustments, and a Bose audio system. That isn't the only Chevrolet model to coming to Australia. HSV also announced they'll be doing the conversion for the Silverado 2500 and 3500HD. Five variants will be on offer from the 2500HD W/T to the 3500HD LTZ. The only engine on offer will be the 6.6L Duramax turbodiesel V8. The Silverado HD arrives in the second quarter of 2018, while the Camaro goes on sale in July. Both the Camaro and Silverado HD will be wearing bowtie emblem, not an HSV one. Source: Holden, CarAdvice Press Release is on Page 2 GM HOLDEN & HSV STRIKE NEW PARTNERSHIP: CAMARO, COLORADO SPORTSCAT AND SILVERADO SET TO STORM AUSTRALIA In a joint announcement, GM Holden and HSV today released details of the new agreement struck between the two iconic Australian companies. The new partnership marks a pivotal moment in HSV’s 30-year history in Australia and begins an exciting chapter in bringing a whole new breed of vehicles to customers. The focus of the new agreement is to utilise HSV’s famed design, engineering, manufacturing and marketing skills across a broader range of product, giving customers access to some of the very best vehicles from across the GM empire. Tim Jackson, HSV Managing Director, said it was fantastic to see the new partnership cemented between the two brands. “This marks a whole new era for HSV and Holden and I hope our customers are as excited as we are. HSV is moving beyond simply ‘hotting up’ existing models, and customers will see two product streams from HSV over the next few years. This is ‘Game-On’ in a very big way.” Holden’s Chairman and Managing Director, Mark Bernhard, said the new agreement was a pivotal step for both companies. “For a number of years, we’ve been talking about bringing customers the best vehicles from around the GM world, and today we’re proud to announce the next step in that strategy. Our partnership with HSV, utilising their world-class engineering and design capabilities, means we’re able to work together to bring the iconic Chevrolet Camaro muscle-car and the best-selling Chevrolet Silverado pick-up, to customers in Australia and New Zealand, not to mention the imminent launch of the exciting Colorado SportsCat. Today is a great day for Holden and HSV, but even more importantly, for our customers”. The first product stream will be what customers have traditionally expected from HSV, being centred around vehicle enhancement and extending vehicle capability beyond the existing Holden offering. “It is important that we continue to play a key role in enhancing Holden’s image in the market place, and potential customers can expect to see us going to work on enhanced products which are a natural extension of the Holden range – the SportsCat is a great example of this approach”, said Jackson. “Some of our traditional customers will expect more power, and if the opportunities present themselves, we will look to develop powertrain enhancements where it makes sense. However, we see an opportunity to appeal to customers by investing in enhanced vehicle specification and capability that really delivers a great driving experience and a competitive advantage in various segments. SportsCat is a great example of how we can deliver improved on-road and off-road driving dynamics, and combine a great new look with improved vehicle capability and versatility. The segment is about much more than drag-strip times,” said Jackson. The second stream of product to be offered by HSV will be the introduction of world-class vehicles from across the GM global range that would not have otherwise been available through Australia and New Zealand. The new agreement has specifically been framed to allow the parties to pursue those programs that make the most sense with consideration for brand development, market-based opportunities, customer preferences, and, of course, commercial viability. The company was, however, quick to emphasise that their overall goal remains unchanged: to create exciting products for niche customers looking for unique vehicles. BRANDING HSV also revealed its intention to introduce a freshened logo concurrent with the introduction of its 2018 range. The new visual identity offers a more contemporary interpretation of the ‘Lion & Helmet’ that has adorned HSV vehicles, and represented the company, since its inception in 1987. “The current logo has served us well over many years, but as the business transitions to encompass a far broader array of product offerings, this new logo represents a new and expanded brand promise,” said Jackson. “The Australian market is shifting and, like Holden, we’re shifting with it. This subtle logo change helps signify a new era of vehicle availability from HSV”, he said. “But make no mistake, while it’s a new logo, our customers can expect the same uncompromising attitude to introducing exciting vehicles that Australian’s love to drive”. In terms of vehicle branding, Jackson also confirmed that the two Chevrolet vehicle lines will be marketed as just that: Chevrolets. “Our engineering involvement starts and stops with the conversion of the vehicles from left to right-hand drive. These are iconic Chevys to the core and we’ll let the famed bow-tie speak for itself”, he said. In respect of Holden vehicles that have been enhanced for new segments like the 4x4 space, those products will be designated ‘by HSV’ and wear the ‘Lion & Helmet’ in selected environments like on the front grille. “If we then take some vehicles further up the food chain, and both Holden and HSV believe the best branding approach for the vehicle is to receive the full HSV designation, then we will make that call at the time”, said Jackson. COLORADO SPORTSCAT Playing to HSV’s niche design and engineering capabilities, the Colorado SportsCat features a raft of styling and chassis enhancements that will position it as the most advanced sports 4x4 on the market. To be available in two variants – SportsCat and SportsCat+ – the styling enhancements begin with radically modified exteriors featuring all-new fascias and grilles that, with the addition of LED fog lamps and functional tow hooks, combine to deliver two distinctive and sporty front-end appearances. The SportsCat+ features a rugged “bonnet bulge” while at the side of the vehicle, prominent wheel arch fender flares, smooth-form on SportsCat and casselated on SportsCat+, frame bold 18” x 10” forged alloys wrapped in sports all-terrain Cooper tyres. A stylish hard tonneau, with load-rail provision and quick-release mechanism, combined with a unique sports-bar on SportsCat and sail plane on SportsCat+, enhance the vehicles’ sporty profile, while at the rear, a prominent “Colorado” tailgate applique’ makes a bold statement. The styling enhancements don’t end with the exteriors of the vehicles. The interior also comes in for a substantial make-over to deliver premium levels of comfort and style. SV Sports seats, the front heated, featuring uniquely designed seat foams for optimum support, are wrapped in Jasmine leather and Windsor suede, with this trim combination also adorning the instrument panel. Twin-needle red stitching provides an added highlight, also featuring on the leather-wrapped steering wheel, door trims and centre console cover. Branded floor mats complete the interior style and comfort make-over. From a chassis perspective, the modifications are marked and deliver the SportsCat’s unique driving dynamics. Both SportsCat models feature HSV Sports Suspension with the front spring rate stiffened to 110 Newtons/mm. Its MTV dampers have been tuned around the revised spring rate, with both modifications contributing to a more performance-based handling characteristic. In addition to the increased spring rate, front ride height has been lifted by 25mm. This modification further improves the approach angle of the vehicle, increases ground clearance to the body and reduces the vehicle’s overall rake, delivering a more natural on-road stance. The chassis enhancements continue with the adoption of a Rear De-Coupling Anti-Roll Bar on the SportsCat+. Developed specifically for the vehicle by HSV’s chassis engineers, the de-coupling rear sway bar improves the higher speed road driving performance of the vehicle by controlling rear roll, and thereby improving overall vehicle balance and turn-in transient response. The de-coupling feature ensures the vehicle’s suspension settings can be optimised for off-road performance. SupaShock suspension, as introduced to the Australian market on HSV’s iconic GTSR W1, will also be available as a factory-fitted option on the SportsCat+, taking the vehicle’s suspension capabilities to another level yet again. SportsCat+ also adopts a unique braking package, further enhancing its sporting credentials. Front 4-piston forged AP Racing brake callipers are complemented by 362mm x 32mm diameter rotors and a large (25.4mm) diameter brake master cylinder, to deliver improved pedal feel through a reduction in pedal travel and softness. The functionality of the vehicle’s Traction Control System has also been adjusted to allow for less aggressive interventions, particularly on corner exit. These adjustments also help deliver a more performance-based vehicle response. SportsCat’s stylish 18” forged alloys are wrapped in Cooper (Zeon LTZ Pro) Sports All-Terrain tyres. These Cooper tyres are a hybrid between a sports-truck tyre and an all-terrain tyre and, in addition to their rugged off-road properties, were specially selected by HSV’s chassis engineers for their outstanding on-road performance characteristics, most notably on tarmac and dirt roads. The overall size of the tyres (285/60 R18), and their rolling radius, also delivers a further 20mm increase in vehicle ride height for a total (front) ride height increase of 45mm. In commenting on the engineering enhancements, HSV’s Engineering Director, Joel Stoddart, said “We set ourselves some pretty aggressive targets heading into the SportsCat program. We wanted to set the bench-mark for on-road performance without compromising the vehicle’s off-road capabilities. In fact, we’ve managed to improve the vehicle’s off-road performance, so I’m confident the team has delivered on both counts”. In addition to the styling and engineering enhancements developed by HSV on the new SportsCat range, the vehicle also carries over a raft of core vehicle features that help complete the premium offering. From a performance perspective, both SportsCat models are powered by a 2.8 litre double overhead cam Duramax Turbo Diesel engine that offers 147kW of power and up to 500Nm of torque when specified with the optional 6-speed automatic transmission with Active Select. A 6-speed manual transmission is standard fare. Braked towing capacity of 3,500kg and a maximum payload of approximately 1 tonne deliver impressive workhorse capabilities. The stylish HSV modifications to the interior also complement a breadth of already impressive driver and cabin comforts and technologies including an 8” colour touch screen, embedded Satellite Navigation, a premium 7-speaker audio, a rear-view camera and seven airbags. Said HSV’s Managing Director, Tim Jackson, “Most 4x4’s Pick-Ups are inherently capable off-road – essentially, it’s a category expectation, and we’ll certainly be amongst the best-in-class in this regard, especially with our added ride height and Cooper tyre package. But what we also wanted to do with the SportsCat program was dial up the vehicle’s on-road characteristics, given that’s where most people tend to spend the bulk of their time driving their vehicle. With our unique suspension packages and AP Racing brakes combined with the interior and exterior comfort and styling enhancements we’ve made, we’re confident we’ve developed Australia’s most stylish and advanced sports 4x4”. The SportsCat range is due to start production at HSV’s new facility in Clayton, Victoria, late January, with Recommended Retail Pricing to be confirmed closer to model availability. CHEVROLET SILVERADO For over 100 years, Chevrolet has forged an enviable reputation for building strong and dependable “full-size” pick-up trucks, and HSV has committed to bringing their pinnacle model – the Silverado – to Australia and New Zealand. Power, payload and towing capability are what Silverado is famous for and all these attributes will be reflected in the five-model 4x4 Crew Cab line-up that HSV will offer: 2500HD WT 2500HD LTZ 2500HD LTZ “Midnight” Edition 2500HD LTZ “Custom Sport” Edition 3500HD LTZ All five vehicles share the same impressive heavy-duty equipment including: Duramax 6.6L Turbo Diesel V8 engine ~332kW of power ~1,234 Nm of torque Allison 1000 6-speed automatic transmission Towing capacity of ~3.5 – ~6.1 tonne (model dependent) Payload capacity of ~1,140kg – ~1,848kg (model dependent) 4-wheel anti-lock disc brakes Automatic locking rear differential Said HSV’s Managing Director, Tim Jackson, “The availability of the Chevrolet Silverado range opens up some wonderful new opportunities for our business in a market segment whose potential is relatively un-tapped, and we believe has high growth potential”. “Whether it be the farming or mining sectors, those who need to pull a large caravan or horse float or simply those who want awesome towing and load carrying capability, Silverado is the pinnacle of the GM range”, he said. Conversion of the Silverado range will commence at HSV’s new production facility in April 2018. The 3500HD LTZ model will be available late in Q2, 2018. Recommended Retail Pricing is still to be confirmed. CHEVROLET CAMARO The Chevrolet Camaro defines performance and this legendary nameplate, in the form of the Camaro 2SS Coupe, will also be imported and converted to right-hand-drive by HSV, and available in 2018. The driving force behind the Camaro 2SS is Chevrolet’s 6.2L Generation V LT1 Direct Injection V8 engine mated to an 8-speed, paddle-shift automatic transmission and generating up to 340kW of power and 615Nm of torque. The vehicle’s Performance suspension provides a dynamic connection to the road with stopping power delivered by 4-piston Brembo front & rear performance brakes with fixed callipers. High Intensity Discharge (HID) headlamps and LED Daytime Running Lamps deliver signature front-end appeal while stylish 20”, 5-split-spoke alloys (8.5” front & 9.5” rear) are wrapped in 245/40ZR20 (front) and 275/35ZR20 (rear) Goodyear Eagle tyres. A rear stanchion spoiler and dual-outlet exhaust with bright tips add aggression at the tail. The interior of the Camaro 2SS delivers the perfect marriage of form and function. It starts with power-adjustable heated and ventilated leather-trimmed front sports bucket seats for optimum comfort and support, complemented by a leather-wrapped, flat-bottom sports-profile steering wheel for ultimate grip. Dual zone automatic climate control, a 9-speaker Bose premium audio and 24 colour interior spectrum lighting enhance interior ambience while the Head-up Display, Drive Mode Selector and Enhanced Driver Information Centre blend exhilaration with innovation. Conversion of the Camaro 2SS is due to commence at HSV in July 2018 with Recommended Retail Pricing still to be confirmed.

In addition to the styling and engineering enhancements developed by HSV on the new SportsCat range, the vehicle also carries over a raft of core vehicle features that help complete the premium offering. From a performance perspective, both SportsCat models are powered by a 2.8 litre double overhead cam Duramax Turbo Diesel engine that offers 147kW of power and up to 500Nm of torque when specified with the optional 6-speed automatic transmission with Active Select. A 6-speed manual transmission is standard fare. Braked towing capacity of 3,500kg and a maximum payload of approximately 1 tonne deliver impressive workhorse capabilities. The stylish HSV modifications to the interior also complement a breadth of already impressive driver and cabin comforts and technologies including an 8” colour touch screen, embedded Satellite Navigation, a premium 7-speaker audio, a rear-view camera and seven airbags. Said HSV’s Managing Director, Tim Jackson, “Most 4x4’s Pick-Ups are inherently capable off-road – essentially, it’s a category expectation, and we’ll certainly be amongst the best-in-class in this regard, especially with our added ride height and Cooper tyre package. But what we also wanted to do with the SportsCat program was dial up the vehicle’s on-road characteristics, given that’s where most people tend to spend the bulk of their time driving their vehicle. With our unique suspension packages and AP Racing brakes combined with the interior and exterior comfort and styling enhancements we’ve made, we’re confident we’ve developed Australia’s most stylish and advanced sports 4x4”. The SportsCat range is due to start production at HSV’s new facility in Clayton, Victoria, late January, with Recommended Retail Pricing to be confirmed closer to model availability. CHEVROLET SILVERADO For over 100 years, Chevrolet has forged an enviable reputation for building strong and dependable “full-size” pick-up trucks, and HSV has committed to bringing their pinnacle model – the Silverado – to Australia and New Zealand. Power, payload and towing capability are what Silverado is famous for and all these attributes will be reflected in the five-model 4x4 Crew Cab line-up that HSV will offer: 2500HD WT 2500HD LTZ 2500HD LTZ “Midnight” Edition 2500HD LTZ “Custom Sport” Edition 3500HD LTZ All five vehicles share the same impressive heavy-duty equipment including: Duramax 6.6L Turbo Diesel V8 engine ~332kW of power ~1,234 Nm of torque Allison 1000 6-speed automatic transmission Towing capacity of ~3.5 – ~6.1 tonne (model dependent) Payload capacity of ~1,140kg – ~1,848kg (model dependent) 4-wheel anti-lock disc brakes Automatic locking rear differential Said HSV’s Managing Director, Tim Jackson, “The availability of the Chevrolet Silverado range opens up some wonderful new opportunities for our business in a market segment whose potential is relatively un-tapped, and we believe has high growth potential”. “Whether it be the farming or mining sectors, those who need to pull a large caravan or horse float or simply those who want awesome towing and load carrying capability, Silverado is the pinnacle of the GM range”, he said. Conversion of the Silverado range will commence at HSV’s new production facility in April 2018. The 3500HD LTZ model will be available late in Q2, 2018. Recommended Retail Pricing is still to be confirmed. CHEVROLET CAMARO The Chevrolet Camaro defines performance and this legendary nameplate, in the form of the Camaro 2SS Coupe, will also be imported and converted to right-hand-drive by HSV, and available in 2018. The driving force behind the Camaro 2SS is Chevrolet’s 6.2L Generation V LT1 Direct Injection V8 engine mated to an 8-speed, paddle-shift automatic transmission and generating up to 340kW of power and 615Nm of torque. The vehicle’s Performance suspension provides a dynamic connection to the road with stopping power delivered by 4-piston Brembo front & rear performance brakes with fixed callipers. High Intensity Discharge (HID) headlamps and LED Daytime Running Lamps deliver signature front-end appeal while stylish 20”, 5-split-spoke alloys (8.5” front & 9.5” rear) are wrapped in 245/40ZR20 (front) and 275/35ZR20 (rear) Goodyear Eagle tyres. A rear stanchion spoiler and dual-outlet exhaust with bright tips add aggression at the tail. The interior of the Camaro 2SS delivers the perfect marriage of form and function.

  3. Chevrolet has revealed the two extremes of the Silverado family, the 1500 and the Class 4, 5, and 6 trucks. But the HD variant has yet to make its debut. Today, Chevrolet dropped a teaser for the upcoming 2020 Silverado HD. This would be ok if it was a couple of months out from being shown, but Chevrolet isn't planning to show until late 2019. That's right, we have an 18-month wait. The photo shows the top half of the Silverado HD's front end and it looks tough. We can see the headlights being similar in shape to the 1500 and the Chevrolet script running the whole length of the grille. We're expecting a number of grille inserts depending on the trim. A chrome-ringed hood scoop provides extra cooling for the engine - possibly a diesel engine. Source: Chevrolet Press Release is on Page 2 CHEVROLET TO REVEAL THREE ALL-NEW SILVERADOS IN 18 MONTHS Next-gen Silverado HD previewed prior to its 2019 reveal DETROIT — Chevrolet announced that the next-generation Silverado HD will debut next year, as a 2020 model. It will be the third all-new truck in the Silverado lineup revealed in just 18 months, joining the 2019 Silverado 1500 and the 2019 Silverado 4500/5500/6500HD. “Chevrolet already fuels the most successful truck manufacturer in the industry,” said Alan Batey, global head of Chevrolet. “With a completely new, expanded range of Silverado models on the horizon, we expect to see even more truck buyers in Chevrolet showrooms.” The next-generation Silverado HD is designed for the specific priorities and needs of heavy-duty truck customers. On-road testing of the new Silverado HD prototypes will begin in the near future to reach Chevrolet’s increased durability and validation standards, and the bolder, larger proportions of the truck will be instantly apparent. More product information will be provided next year, with the first production models scheduled to roll off the assembly lines in Flint, Michigan, in the third quarter of 2019.

  5. 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. Source: Chevrolet, GMC Press Release is on Page 2 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. Also, the Tow/Haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads. There’s also a smart diesel exhaust brake feature that enhances control when descending steep grades.

  7. 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.

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.
