For 2014, Jeep Grand Cherokee delivers a best-in-class 30 miles per gallon (mpg) highway courtesy of a new 3.0-liter EcoDiesel V-6 engine for North America and a new eight-speed transmission. The new 3.0-liter EcoDiesel V-6 boasts an unmatched driving range of more than 730 miles.
A new eight-speed transmission drives the new EcoDiesel, as well as Grand Cherokee’s 3.6-liter Pentastar V-6 engine – now achieving up to 25 mpg highway and more than 600-miles driving range – and its 5.7-liter V-8, now achieving up to 21 mpg highway.
Among all of the many new 2014 Jeep® Grand Cherokee features, two in particular contribute to vastly improved fuel economy and driving performance: a new, clean, 3.0-liter EcoDiesel V-6 engine and a new eight-speed automatic transmission.
Jeep Grand Cherokee’s new 3.0-liter EcoDiesel V-6 engine is expected to achieve 30 mpg highway with a driving range of more than 730 miles. The award-winning Pentastar V-6 engine delivers 25 mpg, with a best-in-class range of more than 600 miles. And the legendary 5.7-liter V-8’s fuel economy improves 5 percent, now achieving 21 mpg.
Enthusiasts in North America have been clamoring for a diesel-powered Grand Cherokee and Jeep has delivered. Producing a class-leading 240 horsepower and massive 420 lb.-ft. of torque, the 3.0-liter EcoDiesel is capable of towing 7,400 pounds – more than any competitor’s V-8 equipped SUVs. With a 30-percent increase in fuel economy and a 56-percent increase in torque versus the Pentastar V-6 engine, the EcoDiesel achieves 21 mpg in the city and 30 mpg on the highway in 4×2 models. This allows for a best-in-class driving range of more 730 miles. Full-time 4×4 models have fuel economy figures of 20 city and 28 highway.
The new, 50-state legal, clean 3.0-liter EcoDiesel engine produces low CO2 emissions. MultiJet II common-rail injection and Selective Catalyst Reduction (SCR) help this new engine achieve these results.
The 24-valve, dual-overhead-cam engine features a block and bed plate crafted from strong compacted graphite iron (CGI), which contributes to stiffness without penalizing performance.
