When I drove the Grand Cherokee CRD around DaimlerChrysler's proving grounds in Chelsea, Mich., it delivered as promised. It's ridiculously gutsy from a standing start, even with the relatively heavy Quadra-Drive II four-wheel drive underfoot. It's no surprise, because the engine puts out 376 pounds-feet of torque at 1,600-2,800 rpm, as well as 215 horsepower at 3,800 rpm. What makes this engine stand out, though, is how quiet and smooth it is. It's definitely the most refined diesel engine I've ever driven in a car ? or light truck, as the case may be.
The 3.0-liter V-6, which has been used in the Grand Cherokee overseas, is a Mercedes engine that is arguably the most advanced small diesel made. When you start ? and particularly when you stop ? the engine there's no vibration that shouts "diesel."
