The Mercedes-Benz S-Class is ultra-luxurious, ultra-refined, and ultra-comfortable luxury sedan. The refreshed 2010 S-class trims includes the S550 (available with rear-wheel or all-wheel drive), S600, S63, S65 and new for 2010, the S400 Hybrid. This luxury car come with a slew of new and improved high-tech systems, including safety and convenience features. The S550 is equipped with a standard 5.5-liter, V8, 382-horsepower engine. A 7-speed automatic transmission with overdrive is standard. The top-of-the-line S600 is powered by a twin-turbo V12 engine mated to a heavy-duty five-speed automatic. For the performance oriented driver, this sedan offers two models; the S63 AMG and the S65 AMG equipped by twin-turbo 6.0-liter V-12 engine. Both enhance their sporting aspirations with features such as 20″ performance tires and AMG-specific bucket seats. Specially tuned computer-controlled ABC active suspension system with AMG shock absorbers delivers decidedly sharper handling characteristics. MSRP: $91,600 – $149,700. [Source: Yahoo Autos]
