Alfa Romeo 4C finally on sale in 2013?

It seems the Alfa Romeo 4C may finally arrive in production guise at the 2013 Geneva Motor Show, and on sale soon after. First seen at the Geneva Motor Show in 2011 – when we expected it to go on sale in 2012 – the 4C has been rolled out by Alfa Romeo a few times since – even complete with ‘teasers’ when all that had changed was the colour – to keep up interest in a car that holds much promise but didn’t seem to be heading anywhere. But now, according to Autocar, Alfa Romeo has confirmed that a production version of the Alfa 4C will arrive at the 2013 Geneva Motor Show before going on sale – at least in Europe – later in the year.

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.

The Porsche 911: the car that shouldn’t work but does

Like a sling shot, the heavy engine at the back is always trying to overtake the driver in front. Anyone can understand that.Yet the Porsche 911 - one of the fastest cars on the market, and one of the most enduring in history - has its engine at the back.
