    GM's CEO Says They Are A Leader In Self-Driving Vehicles


    • Mary Barra Says GM Is A Leader In Autonomous Vehicles..

    Mary Barra, General Motors' CEO tells USA Today in an interview that the company is "among the leaders" in the development of self-driving cars. Now this claim seems a bit dubious since the only pieces of self-driving technologies that GM is working on is the Super Cruise system that will be debuting on the Cadillac CT6. and the company disclosing that it's running a fleet of driverless Volts at the Warren Technical Center. The remaining efforts are being kept confidential at the moment.

     

    "Things are moving quickly in autonomous (cars) because there's so many different pathways and the standards aren't even set. A lot of people can claim leads because people are making advancements in different areas," said Barra.

     

    We recommend you check out the rest of the article as Barra talks about Apple, Tesla, and the current relationship with NHTSA.

    As an enthusiast I see the self driving car is the Anti Christ of the automobile. To me this is the end of the car enthusiast and it will render automobiles as just pods to move us from place to place.

    I know "have you ever driven the 405 at rush hour?" The answer is yes but have you ever driven The Tail of the Dragon in Tennessee?

    I just hope this all drags out long enough I will be too old to drive by then.

    I too agree with Hyper with self-driving automobiles as the Anti-Christ.

     

    Ill go further still and borrow hatred for anything remotely robotic in such movies as Terminator and iRobot.

     

    Im not however down with vintage iron being my sole choice though...

     

    No...not because I dont like vintage iron...au contraire...I LOVE vintage iron....its just that the cold cold winters of Quebec....my home...creates havoc for the metal through an insane amount of corrosion in a relatively short amount of time...

     

    You know...the stupid salt that we use to melt that stupid snow. And the thawing and freezing that goes on...is not that much better for the cars themselves...

     

    On the upside...when one is 70 years old, in Quebec, they make you take a practical driving test again, to see if your fit to drive...then and only then will the apocalypse be fine with me, if and when the Quebec government deems me too old to drive...but then again, I might be living in Greece by that time...spending all my time on a beach...who needs gas, or electricity or hydrogen? A couple of watermelons to feed the horse and she takes you back home...come to think of it...THAT would be the ORIGINAL self-driving automobile...and I presume much much safer...horses dont make a habit of getting hacked or crashing into one another...and I dont seem to recall horses rebelling against us humans ever in history...

    Add me at 48 years old as saying self driving auto's are for those that should never have been allowed to drive anyway as their facebook and twitter is more important to them than enjoying the thrill of driving. 

     

    I have to wonder just how many new auto's are in my future as I am not a fan of all the safety crap that takes control of your auto and would rather enjoy driving a true auto with no self braking, self driving, etc.

    Amen to that DFELT...to both your points about dummies that use their electronic device while driving...yeah...those a-holes are the reason for this mania over self driving cars...

     

    I too, hate most safety features in most cars...the absolute most I want in my car is airbags, seatbelts, ABS brakes and traction control for certain situations. Not all...And that is it....No...No back-up cameras, no beep beep beeps, no lane departure warning systems, no nothing.

    No smart cruise control, no radar/camera interventions of any kind....

     

    If humans were more conscience in their driving, most of these features would not even be needed...

    The real wall will be at some point they will have to remove the free radical here the person with the non self driving car. This is the one thing they have no control over and it will have to be removed. I wonder how they are going to deal with that.

    Also my other concern is you are turning your vehicle over to the system. This means if someone out there says there is too much traffic on the 405 at 5 PM you can not go that way even if you want to at that time. They may like a bus route assign times you can travel which means you may take longer getting home or you may not even be able to stop at a store on the way home if the traffic control division says you can't.

    Also if they would like to restrict movement of people from one region to another they can do that too.

    While this may be a Utopian dream for some it could prove to be a major factor in taking away your liberty to travel as you see fit today. In the hands of the wrong people it could really be a problem.

    If you do not think it could happen the government now is thinking about making you put a smart thermostat in your home. They already are putting smart appliances that control the output of appliances in some areas now. Same with electric meters.

    The Big Brother thing was set for 1999 but it was just a little bit late.

    Not saying this will happen but the tools will be in place to make it happen if someone thinks they can live your life better for you. I think the government now is a little too far on that now.

    My thoughts on GM being a leader: well, in order for them to be competitive, they have to be. It's something that no automaker can ignore. And I think no automaker can really pinpoint why they're going down this road; but I'm happy that Tesla and GM are leaders here, and I guess Ford couldn't be that far behind in that realm either. Heck, Toyota, Audi from VW Group, Volvo. Every well known company for sure is pursuing this tech. But I don't think any company that does it first has a lasting advantage either. This is more of just taking components for the most part already available and tuning the hardware and developing the software to enable these features. Not much invention as much just minor innovations that add up to these systems. 

     

     

    Other thoughts -

     

    Yeah, smart thermostats and kwh meters are just junk. It's all a cash grab. Turning off the lights when you leave a room and setting the thermostat at 65 or 18 Celsius are just plain common sense. And the loss of privacy. In order to 'serve' us you better they track usage and package customer information for sale to the highest bidder.

     

    I think mandating self-driving cars.... while certainly possible; at the rate these technologies are coming down in price; and just the salivation of politicians and lobbyists of the potential benefits; no, no. 

     

    Honestly, I'd rather we supersede driving with something kickass like hoverboards, teleportation, jetpacks, mini Jetsons; Capsule Corp flying thingermajiggers, or the hyperloop.... or something so simple and ridiculously cheap like bicycles of all things. Walking even... 

     

    And the leave the roads empty for those who choose to drive with passion.

    Also if they would like to restrict movement of people from one region to another they can do that too.

    I have no doubt that some are already daydreaming about this, but implementation would require a Consitutional Amendment.

    Not at all happy about the prospect of losing control of my own vehicle.  May as well not own my means of transport, but take public transportation... then the automakers eventually go out of business.

    We all are looking at this from one direction the question is outside the metro areas like LA etc. just how popular will this technology be?

    I can see many areas where this will not play well.

    Just exactly how will the public take this all in.

    Here's my take. Hybrids / electrics, after 15 years on the market, are still under 5% of the market IIRC. SDCs still have numerous, tall hurdles to clear, not the least of which is legalities. 15 years from now, are they going to be doing any better than hybrid/EVs?? 

    It seems SO often people are willing to speak on the concept meanwhile ignoring the numbers. It's like CUVs- they've only gained a whopping 5% in share over the last 6 years, but people sometimes talk about them as if it were a landslide shift.

    SuperCruise is not the only tech that GM is working on at the moment.

     

    GM is funding some large self driving initiatives that may not directly have their name on it, but they get rights to the tech as it is developed.  Pittsburgh is a major hub for such development. Uber, Google, and Carnegie Mellon University are all working on it here.

     

    It's not coincidence that all of the CMU self driving cars happen to be Cadillacs.

    I think self driving is a good idea, 60 minutes had a good story on this a couple weeks ago.  They said 33,000 people die in car accidents every year, the same as if a fully loaded 747 crashed every week.  If the airline industry had a 747 crash weekly, no one would fly, yet people hop in a car and do distracted driving, or fall asleep, or drive drunk etc.  Self driving cars will save lives.

     

    Secondly, stop and go traffic can be stressful, letting the car take over in driving like that keeps the driver calm, relaxed, makes the drive more pleasurable.  I like driving, I don't like sitting in stop and go traffic doing nothing, and wasting time.   The Self driving car could create time, the ultimate luxury.  Doesn't mean you still can't drive for thrills.

     

    And GM is not the leader, this car is, 20,000 miles driven by the computer on public streets without an accident.

    That's the thing really. These self-driving systems do not have to be perfect as we think. They just have to be better than humans. Which is highly likely. Add to that, there's just an untapped amount of information governments and automakers and third parties like insurance companies would just love to snack on... that can be provided from a self-driving vehicle connected to the cloud.

     

    Now, I think for any SDC to gain traction, you need more than just the automaker accounting for liability, like already companies are declaring. They need to demonstrate system reliability. And how their self-driving cars...could actually prevent accidents from happening with non self-driving cars.

    I think the article's title and body do not really imply GM as the overall leader as much as GM is among the big leaders in this emering automotive field.

     

    And autonomous tech is kind of like any technology, really. Which means easily* reproducible and substitutable in many cases. GM is among the leaders, while companies like Mercedes and Tesla (they've already brought it to market) in production vehicles, I am very sure all the technology demonstrators by all cars are very alike in capabilities.

     

    It's also just a part of the big autonomous 'auto's movement. So things from warehouse carts to mining dump trucks to huge freighliners all being able to demonstrate in daily use autonomous navigation ability.

     

    *As in easily I mean in the context of academic settings like MIT, Silicon Valley, Pittsburgh, and/or private enterprises with the resources to dedicated to this emerging technology.

    Another Pittsburgh plug. The optical tech that allows a car to see like a human in order to judge distance and relative speed for self driving cars was largely conceptualized and developed here. This is different from the laser/radar based cruise control systems and is a crucial piece to the SDC puzzle.

    I think a car maker will crack this before Google, Apple, CMU, MIT or whoever does.  Because those firms are outfitting stuff to an existing car from another company, vs the car company expanding upon their own tech and building from the ground up.  What is shocking is a Mercedes engineer said the self driving tech would only add a few thousand dollars to the price of the car.   And rumor is the 2017 E-class will have it.  $3k on the price of an E-class is nothing, so $65,000 vs $62,000 and it drives itself, amazing.

    German/English translation error? It may only cost Benz that much to add to the car, but you better believe they're going to extract a bunch of profit from you at the dealership.

    Besides, Drivers Assist and Parktronic is priced at $3,500 today and requires $4,000 of other packages as well.

    Self driving is only going to be seen on really expensive cars for a good while. Self-driving on a $65k car?

     

    Not likely in the least. You probably have to buy every option to enable the purchase of their special self-driving version of Distronic.

     

    Or worse, in order to get even basic distronic adaptive cruise control, you have to buy self-driving.

     

    In either case, the leaders in this field are going to be the ones who can bring it to a price point for the masses. GM, Honda, Ford, and Toyota, Volvo and Subaru seem like the only car companies that could achieve this relatively soon.

    The Driver Assistance package which has Distronic plus with steer assist, lane keep assist, adaptive cruise, etc is a $2,800 option on the  S550, and a $2,800 option on a C300.  Perhaps they charge another $2,800 on top of that package.  It is just what the engineer said, he expects a few thousand dollars will be added to the price of the car.

     

    The E-class is going to be more autonomous than the current S-class, Mercedes has already stated that it will have more technology than the S-class has right now.  We'l find out in January.

      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.

      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 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.
