The Aspen's suspension is the same independent, double-wishbone front design with a non-independent solid-axle rear that is found on the Durango. The interior has many wood-like trims and either cloth, leather, or leather-suede seats. It comes with the option of a 235 horsepower 4.7-liter V-8 or a 335 horsepower 5.7-liter Hemi V-8 engine. Both engines are mated to a five-speed automatic transmission and the more powerful V-8 is capable of shutting down 4 cylinders to conserve fuel. Rear-wheel drive is standard and two unique four-wheel drive systems are available.The Chrysler Aspen is an all new model for 2007.
