ronically, it's only years after the big divorce that the Jeep brand finally benefits from the DaimlerChrysler marriage. An all-new Jeep Grand Cherokee debuts for 2011, and it now shares its underpinnings with the Mercedes-Benz M-class SUV. Better late than never, we suppose.
A new 3.6-liter replaces the previous 3.7-liter as the base V-6. It produces 280 hp and 260 lb-ft of torque (up significantly from the old lump's 210 and 235) and returns 11 percent better fuel economy, thanks in part to variable valve timing. The optional 360-hp, 5.7-liter Hemi V-8 returns to the playground, and both engines are paired with a five-speed automatic transmission and either rear- or four-wheel drive.
