Chrysler's 340hp 5.7-liter Hemi V-8 engine powers the 300C Hemi and all-wheel drive Base models through a five-speed automatic transmission. The engine is intelligently able to shut down select cylinders which conserves gas. Standard features such as, SmartBeam headlamps, four-wheel-disc antilock brakes, traction control and an electronic stability control system enhance safety. A 425hp 6.1-liter Hemi V8 powers the SRT8. The Chrysler 300C received a minor external redesign for 2008.
