Jeep Grand Cherokee EcoDiesel From Detroit Auto Show

As if Jeep’s Grand Cherokee didn’t have enough iterations—gas V-6 or V-8, rear- or four-wheel drive, fire-breathing SRT, etc.—the model’s 2014 refresh brings with it a 3.0-liter turbo-diesel V-6

The Jeep Grand Cherokee isn't usually what people think of when you say "green car," but the new diesel version that's coming for 2014 moves it somewhat closer to that category.
Unveiled first thing Monday morning, the 2014 Jeep Grand Cherokee EcoDiesel is part of an updated 2014 lineup for the very successful crossover utility vehicle.

It features a block of compacted graphite iron and aluminum twin-cam heads. Basic specs for the 60-degree six include common-rail injection, downstream emissions treatment via urea, a 15.5:1 compression ratio, and ceramic glow plugs so quick to heat up they might well consign mentions of glow plugs to history. Adding to the allure of the diesel is that, like the 2014 GC’s gas-fired engines, it is backed by a ZF-designed eight-speed automatic.

We suspect that'll produce a combined rating around 24 or 25 mpg.
If you add the popular all-wheel drive option, those numbers fall to 20 mpg city, 28 mpg highway--which we'd peg at 22 or 23 mpg combined.

The 2014 Jeep Grand Cherokee EcoDiesel is a highly capable entry in the world of fuel-efficient SUVs. Unfortunately, it's priced closer to a luxury SUV than a regular midsize model. For drivers who don't mind the $41,000-plus price tag, we suggest adding it to your shopping list.
