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.

The lightweight two-seater is powered by Vauxhall’s turbo 2.0-litre unit – lifted from the Astra VXR – and it’s priced at £29,495. Err, yes – we also feel the SC250’s looks might be a bit of a stumbling block to someone about to flash the best part of £30k on a track-based racer.

And the 2014 Detroit Motor Show has not disappointed, with a substantial number of new debuts and a chance to see some existing favourites, too.
