Each of Detroit’s Big 3 automakers—Chrysler (Ram), Ford, and General Motors (GMC/Chevy)—  recently rolled out or refreshed their heavy-duty diesel pickup models.  All three  now boast powerful turbodiesel engines and so Ward’s Automotive Group is setting out to pick the best of the three at a “Diesel Shootout,” to be held this week at the Robert Bosch LLC test track in Flat Rock, MI.

Editors at Ward’s and its sister Penton Media publication FleetOwner will drive Detroit’s three heavy-duty diesel pickup offerings-- each towing 10,000 lbs-- on the 1.3-mile oval at the Bosch track and on a 20% grade.

Following the template of the annual Ward’s 10 Best Engines competition, editors will score each engine based on acceleration, technology, fuel efficiency, drivability and overall power---  paying close attention to noise, vibration and harshness levels at idle, cruising speed and during hard acceleration. Points will also be awarded based on observed fuel economy and the application of new technology.
