The Grand Cherokee's 3.0-liter, EcoDiesel V-6 engine promises 240 horsepower and the ability to tow up to 7,400 pounds. It's expected to get 21 mpg in the city and 30 mpg on the highway in 4x2 models, and 20 mpg city and 28 mpg highway for 4x4 models. The diesel version will be more expensive than gasoline models. But it's likely to be popular with people who want to tow boats or get outdoors in other ways, says Joe Phillippi, president of New Jersey-based AutoTrends Consulting LLC. It also offers the benefit of savings at the pump, which is key for drivers of bigger SUVs.
