Revolutionizing the BMW M3

BMW is less than a year away from officially revealing the fifth generation of the menacing M3, the first to receive turbocharged six-cylinder power. The performance sedan, code-named F80, is expected to appear as a lightly veiled concept at the 2013 Geneva motor show, debuting the appearance and mechanical package of the M division's eagerly anticipated Mercedes-Benz C63 AMG rival. A showroom-ready version with a production interior arrives at next year's Frankfurt motor show, BMW sources say.

Honda shows off Concept C and Concept S at Beijing motor show

Though it rather closely resembles a late-model Hyundai dressed up in Super Sentai garb, Honda claims that the C's design was inspired by a dragon.
