New details on Mercedes' Porsche 911 fighter

Mercedes-Benz's AMG performance-car division is forging ahead with development of its new twin-turbocharged 4.0-liter V8 powered sports car, nine months before it is scheduled to be revealed at the 2014 German Grand Prix. Known to insiders by its code name, “C190” the two-seat coupe has been conceived to follow in the wheel tracks of the four-year-old SLS at the head of the German carmaker's lineup, aiming to challenge the heady performance and everyday driving appeal of the latest Porsche 911 Turbo at a price that insiders suggest will be in the region of $160,000 when North American sales begin in early 2015. Originally, AMG's new front-engined sports car was tipped to revive the iconic SLC name first used by the SL coupe back in 1971.

German Grand Prix (2014): RESULT

German Grand Prix (2014): RESULT The plan by Mercedes to get a one-two on the grid at the German Grand Prix went awry when Hamilton crashed out in qualifying, but Nico Rosberg starts his – and Mercedes – home Grand Prix in pole position, even if poor Lewis Hamilton languishes at the back of the grid after his brake failure in qualifying. So the 2014 German Grand Prix should be about Hamilton’s quest to reach the Williams cars in second and third, and Rosberg’s disappearance in to the distance. Which it is, but with knobs on.
