Sample quote

More than 98 percent of the Ram Heavy Duty's new frame is high-strength steel, according to the truckmaker. Lighter weight material in the frame, hood, and powertrain have shed more than 140 pounds from the truck's overall weight. Most trucks' wheelbases are incrementally shorter than the models they replace, although their overall lengths are up by about an inch in popular configurations.

Like the outgoing pickup, the new Ram Heavy Duty will be powered by a 6.4-liter V-8 gas engine as standard, or a 6.7-liter turbodiesel inline-6 as an option. The Cummins-built turbodiesel is available in two tunes: with 400 horsepower and 1,000 pound-feet of torque as an option, or 370 hp with 850 lb-ft as standard. The 6.4-liter gas engine, which is more common, makes 410 hp and 429 lb-ft, the same as last year. The 6.4-liter gasser gets a new 8-speed automatic transmission, the turbodiesel sticks with a Aisin 6-speed automatic that presumably can withstand the enormous torque without twisting into a pretzel.
