There are two available engines: the standard 4.7-liter V8 (235 horsepower and 300 lb.-ft. of torque), and the 5.7-liter Hemi V8 (335 horsepower and 370 lb.-ft. of torque). Both are mated to a five-speed automatic transmission sending power to either the rear wheels or all wheels via Chrysler’s full-time four-wheel-drive system. On 4x4 models, the Aspen gets a manual locking diff. The Aspen is based on the Durango’s ladder frame chassis, so it comes with the same brakes and independent, double-wishbone front with a solid axle rear, which tows up to 8,950 pounds. The Aspen comes with 18-inch wheels; 20-inchers are available.
