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 powered by a 228-hp 3.0-liter V6 engine, and gets either a six-speed manual or seven-speed automatic transmission with manual shift mode. The C350 is offered in rear-wheel drive and Sport trim only, and is equipped with a 268-hp 3.5-liter V6 engine and seven-speed automatic transmission with manual shift mode. The enthusiast-oriented C63 AMG boasts a 451-hp 6.3-liter AMG-tuned V8 engine, mated to a seven-speed automatic transmission with steering wheel-mounted aluminum paddle shifters. The C300 is outfitted with a power sunroof, 17-inch alloy wheels, dual-zone climate control, ARTICO upholstery and Bluetooth wireless connectivity. The C350 adds a rear spoiler, heated front seats, a 60/40 split-folding rear seat and satellite radio, while the C63 AMG is further equipped with 18-inch alloy wheels, AMG sport seats and exclusive aluminum and carbon fiber trim elements. Standard safety features 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, driver's knee airbag, overhead curtain airbags for front and rear occupants and a tire pressure monitoring system. The Mercedes-Benz C-Class carries over with minimal changes for 2011. Sport trims receive new LED daytime running lights, and the C350 is now equipped with a standard 60/40 split-folding rear seat.
