According to TFL Truck, a new, much larger Duramax could be on the way. Hosts Roman and Andre have coined it the “Megamax.” To put this in context, the engine in the Bugatti Veyron, one of the world’s most powerful supercars, is a scant 8 liters. “The next Duramax engine could have upwards of 600 horsepower and 1,200 pound-feet of torque,” says Andre almost in disbelief. Is TFL’s source correct? Time will tell.
