In the never ending push to make diesel “ring” with U.S. consumers, automakers continue to explore more of the diesel landscape. And doing so first among light-duty full-size pickups is this 2014 RAM 1500 EcoDiesel.

The 1500 Eco-D grabs power from the same Italian 3.0-liter turbodiesel V6 we loved in the Grand Cherokee. Output rates 240 horsepower. Torque is 420 lb-ft, or more than Ram’s Hemi V8. Despite noticeable turbo lag, the diesel’s throttle response was great: manageable, and most importantly, livable.

Our Laramie Limited diesel brought the best of the best inside: heaps of leather, whisper-quiet ride, great comfort, and plenty of room with a true Crew Cab setup.

We took the opportunity to compare fuel economy with our Long Term 2013 RAM 1500 Quad Cab with a gasoline-fueled 3.6-liter V6, rated at 305 horsepower and 269 lb-ft.

Both sixes are matted to an 8-speed automatic, have active grille shutters, and ride on four corner air suspension.

While not quite an apples-to-apples comparo…it was close enough to gauge any big differences.

And through a 100 mile test loop of mixed city/highway driving, the diesel averaged an impressive 27.5 MPG, while the gas RAM saw 23.4 MPG. So the diesel does 4 miles per gallon better. That’s a big deal for a big truck, made even bigger when compared to a thirstier gas V8.

But, at what cost? The 1500 EcoDiesel adds nearly $4,000 to a base Ram’s sticker, and $2,850 more than the V8 Hemi.

Still, we think once again the innovative folks at Ram are starting a trend for rival trucks to follow.
