Audi A3 Concept: 400bhp A3 saloon at Geneva

Audi A3 Concept - 0-60mph in 4.1 seconds There we were last week wondering what niche Audi could think of to fill next – as you do in an idle ten minutes – when in to our Inbox dropped news of the Audi A3 Concept.

Porsche 911 GT3 RSR (2011) first official pictures

This is the latest Porsche 911 GT3 RSR, the 2011 version of the famed German sports car company’s range-topping GT racer. The 911 GT3 RSR’s 4.0-litre flat-six engine now produces 449bhp (five whole horses more than the 2010 version) thanks to ECU tweaks, a redesigned exhaust system and a modified air intake housing. Maximum engine revs are a stratospheric 9400rpm, of course it’s rear-wheel drive, and the gearbox is a six-speed sequential unit.

2014 Mercedes C-Class: OFFICIAL – and it looks like a proper baby S-Class

The 2014 Mercedes C-Class (pictured) looks like a proper baby S-Class The 2014 (or 2015 if you’re in the US) Mercedes C-Class has finally been officially revealed ahead of its debut at the Detroit Auto Show next month, and it looks to be a convincing take on a proper scaled-down S-Class. With Mercedes launching a more credible range of compact cars beneath the C-Class – with the new A-Class and CLA – targeting younger, funkier buyers, Mercedes has taken the C-Class from the ‘entry-’level’ real Mercedes to become a properly grwon up luxury saloon, just smaller than its E-Class and S-Class siblings. The new C-Class is wider, longer and has a longer wheelbase – with most of the extra 3 inches in the wheelbase benefiting the rear passengers – yet it’s lighter and more dynamic than the model it replaces, thanks in no small part to an aluminium hybrid body that now has up to 50 per cent aluminium in its panels.
