It's tough to sell a heavy-duty pickup truck without a diesel engine offering. Ford uses Navistar, General Motors has worked with Isuzu Motors and Chrysler has Cummins. Of all the automaker diesel offerings, Chrysler's pact with Cummins has lasted the longest (since 1989), and word from Chrysler's official blog is that the two companies will continue to play nicely together into the future. According to a new post on the website, Cummins and Chrysler have agreed to extend their cooperation on a multi-year basis.
Cummins currently builds the 350 horsepower, 650 pound-feet of torque 6.7-liter diesel, which is optional on the Ram 2500 and 3500 and standard on the Ram 4500 and 5500 commercial trucks. Chrysler brags that the very capable powertrain is the only big diesel in the US without a selective catalytic reduction system that requires the owner to add diesel exhaust fluid. The Cummins 6.7 has been able to pass 2010 EPA emissions standards since its 2007 introduction.
