Big things, meet small package: The C43 and C63 cram a whole lot of horsepower under the compact C-class hood. The 3.0-liter twin-turbo V-6 in the C43 makes 362 hp and drives all four wheels through a nine-speed automatic transmission. Step up to the racier, rear-wheel-drive C63 and revel in 469 hp from its 4.0-liter twin-turbo V-8; a seven-speed automatic is standard. Both models are available in sedan, coupe, or cabriolet form. Craving more? Try the C63 S—it gets a bump to 503 hp.
