The C-Class is offered as three models: C300, C350 and C63 AMG. The C300 is available in rear-wheel and 4MATIC all-wheel drive configurations, both in either Sport or Luxury trim levels. It is equipped with a 228-hp 3.0-liter V6 engine, and gets either a six-speed manual or seven-speed automatic transmission with TouchShift manual shift mode. The C350 is offered in rear-wheel drive and Sport trim only, and is powered by a 268-hp 3.5-liter V6 engine, paired with the seven-speed automatic transmission with TouchShift. The enthusiast-oriented C63 AMG boasts a 451-hp 6.3-liter AMG-tuned V8 engine, mated to a seven-speed automatic transmission with AMG SPEEDSHIFT PLUS manual shift mode and steering wheel-mounted aluminum paddles. Every C-Class model is outfitted with standard safety features that include stability and traction control systems, 4-wheel anti-lock disc brakes with brake assist, active anti-whiplash front head restraints, front side-impact airbags and side-curtain airbags for front and rear occupants. For 2009, the Mercedes-Benz C-Class carries over with minimal adjustments to standard and optional equipment. Changes include two additional pelvic airbags integrated into the front seats on all models, while the C350 gets a standard power steering column and driver's side memory function.
