    General Motors Accidentally Releases, Then Deletes Info On Updated Duramax V8


    • We get our first clues as to what the next Duramax V8 is producing

    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.

    With those power figures so similar I'm curious about the characteristics of each engine/trans combo. Mostly because the 5hp advantage but 15tq disadvantage the Duramax has just sounds like a slightly awkward swing when it comes to diesels so I'm curious what their dynos look like.

    Hood looks GREAT. Now, if they could NOT outline the vent in chrome that would be nice.

    Being the Denali edition, I expected all the Chrome, but I have to imagine that this in basic or mid trim form would be more monochromatic.

    4 years later and they were already over 600 lb-ft.

    It's crazy that these pick ups have over 900 lb-ft of torque now.  I remember about 15 years ago when a Silverado or Ford diesel truck had like 450 lb-ft and that was considered a lot.

    This is the 34yr chart I love to look at and see just how far and how fast in the last 10 years we have really come.

    I keep waiting for one of them to boast numbers at or over 1000. 

    Probably for the 2018 model year. I bet someone will say we have 1001 Foot pounds of torque. :P

    I'd day most people buying these trucks have no business moving the loads the trucks are capable of hauling/towing. Im sure they have no training in regards to managing loads that heavy.  Advertised towing of 30,000 pounds on a pickup is crazy.  If you are constantly towing that much you should be in at least a class 5 rig. Class 6 would be even better. 

    You can't even use the capabilities of these trucks without endorsements on your license. But I dont expect many of the buyers to know that either.  Hopefully some owner of one of these trucks don't put others in danger because of a salesman and TV comersial.

    They keep increasing power to levels that are beyond what a pick up truck needs and are getting more into medium duty commercial truck area.  So what does that do to weight and cost of the pick ups?  There is a point when it is senseless, if the Silverado HD diesel is like $70,000, doesn't really matter if it has 1,000 lb-ft if no one can afford it.

    You can almost say the same exact thing word for word with the Mustang and Camaro(and maybe if the Challenger ever get's redone). Their power levels are about race car levels, not many can really extract their performance out of them, prices are outrageous...

    Wut? Truck approach these prices right now, and the truck lines outsell anything else on the market. Weight is also not an issue; I don't believe the Duramax power train is any heavier after going from 450 TRQ to 900 TRQ.

    If you are one of the many who dismiss the need for working trucks to tow and haul safer and easier, yet praise 707hp coupes for quadrupling speed limits....raise your hands.

     

    Meh, don't bother, we already know.

     

    Kudos to GM for offering it's working customers, you know, those who actually buy and use the products....exactly what they are asking for.

    I have said this about the Mustang and Camaro also.  If the Camaro is $60,000, it isn't really a Camaro anymore.  The Camaro used to be priced like a Malibu or Monte Carlo, it is was middle price Chevy, not they want Cadillac prices for it.  If you want a $60,000 sports car that is why the Corvette exists.  It would be nice if they offered a cheaper sports car if they are going to push Camaro and Corvette up market, but at the same time, sports car sales are dropping across the board, so it probably isn't worth it.

    Camaro starts @ $25.9K. Malibu starts @ $21.6K. They are both below the new car ATP and in the same ballpark.

    Where the picture differs is that there are that many more layers above the base Camaro now, and that many less in the Malibu line. That's where the Camaro now can earn much higher stickers in high trim levels. Good for GM, good for those who are demanding such. There is nothing equivalent to the Chevelle Malibu SS396 anymore, or there'd be correspondingly higher trims there, too. 

    And yep; a $60K Camaro is still a Camaro, just as a ZL1 Camaro was one at double it's base MSRP back in the day. Try again.
