The 2009 Chrysler Aspen gets a new gas/electric Hybrid model and more available power. Otherwise this premium midsize SUV is largely unchanged. Aspen is a luxury-trimmed version of Dodge's Durango. The two share traditional conventional gasoline V8 and hybrid powertrains, as well as seating for up to eight. Aspen comes in a single Limited trim level. Standard on conventional models is a 303-hp 4.7-liter V8 engine. Optional is a 376-hp 5.7-liter version of Chrysler's Hemi V8. That's a 41 hp increase over the '08 Hemi. Hybrids have a 5.7-liter Hemi V8 that pairs with a battery-powered electric motor for 385 hp. They can run on either gas or electric power or both, depending on driving needs. No plug-in charging is needed. Both 5.7-liter engines have Chrysler's Multi-Displacement System, which shuts down four cylinders when cruising in order to save fuel. A 5-speed automatic is the only transmission in gasoline models, while the hybrid gets a continuously variable automatic transmission (CVT). Conventional Aspens are available with rear-wheel drive or all-wheel drive. Hybrids are AWD only. Maximum towing capacity is 8900 lb for conventional models, 6000 lb for the Hybrid. A low-range gear for off-roading is an option on non-Hybrid AWD models. Available safety features include ABS, traction control, antiskid system, curtain side airbags, and front side airbags. Standard seating is for eight with a 2nd-row bench; optional buckets reduce it to seven. A power liftgate and rearview camera are standard on all models. Leather upholstery and navigation system are standard on Hybrid and available on other models. DVD entertainment is optional on all. Evaluations of the 2009 Chrysler Aspen Hybrid are based on preview test drives.
