3.0L EcoDiesel V-6

Italian Diesel Provides Class Leading Fuel Economy

Ram Truck's groundbreaking introduction of the 3.0L EcoDiesel to the Ram 1500's lineup has been met with overwhelmingly positive reviews and reception. Their instant success is due in part to the engine's impressive characteristics, offering a balance between capability and fuel economy. The engine's 420 lb-ft of torque allows the truck to tow just over 9,000 lbs, while its relatively small displacement grants it an EPA rated 29 mpg on the highway (for two wheel drive models). But the diesel powered Ram 1500's success also comes from another key element - there's been no competition in the 1/2 ton diesel category, but other automakers are catching on quickly.

Ram had a chance to produce their 1500 model with Cummins' 5.0L turbodiesel but declined the offer, citing concerns over fuel economy goals. They chose instead the 3.0L EcoDiesel, which is manufactured in Italy by VM Motori (Fiat-Chrysler has since acquired VM Motori). For an engine displacing under 200 cubic inches, the EcoDiesel impresses with 240 horsepower and 420 lb-ft of torque. Power is transmitted through an 8 speed transmission designed by ZF, whose favorable features include a short 4.71 1st gear ratio and relatively tall 0.67 overdrive. Like the 5.0L Cummins, the EcoDiesel's engine block is produced from CGI and its cylinder heads from aluminum, both of which help reduce weight.
