Dave: a couple things:
Isn't this about the 6.4?Rated at 470 hp in SRT cars, but retuned to meet the needs of truck buyers, the new 6.4 liter gasoline engine produces 410 horsepower and 429 lb-ft of torque. The diesel was, according to a Ram engineer, designed from the ground up for trucks; it includes an active runner intake, for both low end torque and high end power. The power ratings are best in class. It delivers the same torque as a key competitor, but at lower engine speeds.
The company also announced that the link/coil rear suspension design of the Ram 1500 will be used in the Ram 2500 and Ram 3500 as well; this will, according to a company spokesman, dramatically improve the pickups’ handling and ride, without reducing cargo or towing capacity. The Ram 25000 will also have an optional active air suspension.
