World's smallest car enters the record books

Texas is the US state that's big on… well, being big. So it's slightly surprising that a Texan has just entered the Guinness World Records book for creating the world's smallest roadworthy car. Is this his answer to our increasingly congested city streets?

Brabus turns the Mercedes-Benz E63 AMG up to 850 hp

While other German tuners' cars sometimes answer questions no one asked, Mercedes-Benz tuning house Brabus has tended to answer questions that many were too scared to ask. One such question was: what would an 850-hp E-class sedan be like? The answer comes in the form of their latest reworking of the E63 AMG sedan (itself no slouch, it should be noted), called the 850 6.0 Biturbo.

VW Beetle GSR: Price from £24,900

The Beetle GSR is a homage to the Yellow-Black Racer Beetle from the 1970s (GSR stands for Gelb Schwarzer Renner – which means Yellow-Black Racer) which featured a similar paint job, boosted power (a whole 49bhp) and was also limited to 3,500 units. But the 2013 version of the Beetle GSR does at least offer much more get up and go than the 1970s GSR managed. That means the GSR comes with VW’s 2.0 litre turbo with 207bhp which is enough to get the yellow Bug to 62mph in 7.3 seconds on its way top 142mph, and is the same power output all Beetles with the 2.0 litre TSI will get from May 1st (up from 197bhp).
