A CP3 injection pump like those found on the fullsize '03-and-later Cummins and Duramax common-rail diesel engines is used to pump 24,000 psi of fuel into the superfast piezo-actuated injectors.
Is It Worth $42,730?While you can purchase a fullsize 31/44-ton truck for about the same price as the base two-wheel-drive diesel Grand Cherokee (MSRP $38,925), that pickup would be a regular cab work truck with vinyl floors and manual window cranks. Every diesel Grand Cherokee comes loaded with a long list of standard features such as leather seats, power windows, climate control, standard side airbags, antilock brakes, traction control, electronic stability programming, and emergency braking assistance. Put that impressive partial list of features in a package that can actually fit in your garage, and you have the new '07 Grand Cherokee 3.0L CRD diesel-the best midsize SUV you can buy today (in 45 states, that is).

The Grand Cherokee interior...
The Grand Cherokee interior is a great mix of American SUV features and German car technologies. The Bavarian-style seats are almost too firm, but they're very supportive and comfortable on long drives. Most controls are easy to read with actual words and numbers instead of maddening international symbols (and, no, the diesel doesn't have a 5,600-rpm redline-that's a gas dash photo). The '08 Grand Cherokees will receive new interior features such as a telescoping steering wheel, a back-up video camera, and Sirius Backseat TV for the kids.
