Power for the Commander comes from the choice of a V-6 or two different V-8 engines. The Sport trim starts with a 210-hp 3.7-liter V6, the Limited gets a 290-hp, flex-fuel 4.7-liter V8 (optional on Sport), and the top-of-the-line Overland has a 330-hp 5.7-liter V8 Hemi (optional on Limited). A five-speed automatic transmission mates all the engines with either a two- or four-wheel drive system. Standard safety features include all-row side-curtain air bags, front-impact air bags, anti-lock brakes w/brake assist, electronic stability control w/roll mitigation and trailer sway control on models with the tow package. For 2008, the Commander adds an all-new 4.7L V8 along with several new entertainment and safety technologies.
