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.
