Ram is preparing to launch updated versions of its line of Heavy Duty pickup trucks next year, which will include some changes to the 6.7-liter inline-six Cummins turbo diesel model.
CarScoops recently spotted a group of pre-production prototypes for the updated Ram HD Cummins testing in the Colorado Rockies. Some of the trucks were simply engine mules and appeared similar to the 2016 model year Ram HDs, while another wore black camouflage to partially mask its redesigned front end.
It’s not clear what upgrades might be in store for the 6.7-liter Cummins diesel engine. Rumors indicate Ram is looking to get back on top of the HD truck torque game for 2017 and may boost the torque of the turbodiesel to well over 900 lb-ft, trumping the 2017 Chevrolet Silverado Duramax (910 lb-ft) and 2017 Ford Super Duty Power Stroke (925 lb-ft).
Other updates, such as a beefed up transfer case, axles and transmission may also be in store to help cope with the added power. Check out the photos over at CarScoops before the new trucks debut sometime in 2017.
