Mercedes-Benz revives its classic Gullwing two-seater as the SLS

Mercedes-Benz's gorgeous 300SL--or Gullwing, as it is affectionately now known--has been reborn five decades after the iconic two-seater first sent the motoring world into a spin at the New York auto show in 1954. We were the first to report Mercedes' secret plans to resurrect the Gullwing following Dieter Zetsche's decision not to forge ahead with a second supercar in collaboration with its Formula One partner, McLaren. Now we can confirm the name--SLS--along with details of its state-of-the-art construction, unique driveline, performance and much more.

SRT Viper logo redesigned for 2013

STR – Street and Racing Technology, Chrysler Groups' new, standalone performance brand – has unveiled the new logo for its 2013 Viper as it continues to tease the new version of its now iconic model. Designed by Chrysler designer Vince Galante, STR says that the logo, christened ‘Stryker', conveys the "sinister look and evil grin of the original, while giving it a more playful appearance." Galante also says the lines of Stryker are indicative of those that will feature on the 2013 STR Viper. Stryker will be the third design to grace the Viper series, following Sneaky Pete and Fangs and was selected from a number of suggestions at the 2010 Viper Owners Invitational.

Alfa Romeo 4C Spider revealed: Geneva Motor Show

The Alfa Romeo 4C Spider (pictured) revealed in Geneva The Alfa Romeo 4C is the epitome of a modern ‘supercar’, with ultra light weight (for a production car) allowing the 4C to produce very good performance from its modest 17500cc engine. So producing an Spider convertible immediately raises the weight issue in a more dramatic way when the car’s abilities are so dependent on it low weight, but it seems the Alfa Romeo 4C Spider – previewed as a production car with a concept at Geneva today – has managed to keep the wight penalties of the convertible 4C down to a minimum. Thanks to a canvas roof and carbon fibre rollover bars, the weight penalty for the Spider is only about 60kg (around a 7 per cent gain) which shouldn’t hurt performance too much.
