That Thing Got an Oil Burner?
Chrysler Group announced its plans to equip the 2007 Jeep Grand Cherokee with a 3.0L common-rail turbodiesel starting in the first quarter of next year in North America. This will be the company's first fullsize SUV application for a diesel motor in North America. The engine was produced by Chrysler's sibs at Mercedes-Benz. It produces 215 hp at 3,800 rpm and 376 lb-ft of torque at 1,600-2,800 rpm; and it achieves an estimated 19/23 mpg.

2007 Chevrolet Silverado Unveiled
It took five long days, hundreds of miles, and more caffeine than one wants to admit to, but after days of watching a commercial photo shoot from afar our photographer finally got a chance to photograph the all-new 2007 Chevrolet Silverado as it sprinted out of a car carrier and ran through a car wash. The camera-ready Crew Cab was decked out in the Z71 off-road package and wearing brochure-red paint. As one can clearly see, this is no Tahoe clone, but rather a unique look including stacked headlamps, which separate the trucks from the SUVs. We're a bit surprised that the Silverado doesn't have some of the signature styling from the 2003 Cheyenne Concept, such as the wraparound glass at the back of the cab, yet we think consumers will be pleasantly surprised with both the styling and car-like refinement that the Silverado is said to have. - Words by Brenda Priddy & company.
