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.

One-of-a-kind De Tomaso Pantera 'ADRNLN' to debut at SEMA

The De Tomaso Pantera, a perfect mash-up of classic Italian styling and American underhood brawn, struck a chord when it debuted at the 1970 New York auto show. Inspired by the Pantera's unique character, custom vehicle builder Ringbrothers decided to restomod and rechristen it “ADRNLN.” It's set to re-debut at the 2013 SEMA show on Nov. 5.

Renault Twin-Z concept (2013) first official pictures

This is the Renault Twin-Z concept (say it 'Twin-Zee'). Although it packs the usual concept car madness of suicide doors, a pared-back cabin and LEDs everywhere, it actually previews the look – and drivetrain – of the next Renault Twingo. The big news is that it'll be rear-engined, rear-drive, and offer an electric option for less money than the £13k Renault Zoe EV.
