This model year, diesel engines are available in the Ford F-150, Chevy Silverado, GMC Sierra, and Ram 1500, with each offering six-cylinder oil burners. This particular Ram 1500 Limited sheds the off-road hardware, and as a result, improves on the Rebel's fuel economy and performance.
Displacement remains 3.0 liters, but Ram has tweaked almost everything else compared to the prior-generation engine, including its water-cooled turbocharger, fuel injection, intake ports, and combustion chambers. The third generation of this DOHC engine, which also is smoother and quieter than before, is assembled at Fiat Chrysler's Cento facility in Ferrara, Italy.
