For all those individuals out there who really need a truck, and use a truck the way it’s meant, GMC has thrown itself into the mix as possible top dog with its latest 6.6 liter Duramax V-8 diesel.660 lb-ft of torque and 365 bhp ensure that if you’re behind the wheel of a new Heavy Duty Sierra, you won’t be looking longingly at anyone else wishing you had more power to move your load. Those numbers give it a 10 lb-ft advantage over its Blue Oval and Mopar rivals, and a 40 bhp advantage over the Ram and 15 bhp over the Super Duty.
Best of all, the motor is covered by a best-in-class 5 year/100,000 mile warranty
Our take? Those are some serious, serious numbers.
THIS IS VERY NICE VEHICLE,I WANT TO KNOW IT DISPLAY ACTIONS.
