Audi A1 1.4 TFSI (2010) first picture

This new Audi A1 might have a long and convoluted name – it's the A1 1.4 TFSI (136 kW) – but it's not an Audi S1 by another name. While everyone has been expecting a hot version of the A1 to be unveiled at next week's Paris motor show (and this is it), it's not dubbed S1 because there's an even hotter version of the A1 still to come. Meanwhile, this first tuned and tweaked version of the A1 uses the same engine as the VW Polo GTI, Skoda Fabia vRS and Seat Ibiza Cupra.

Porsche 911 GT3 R (2010) first pictures

This is the Porsche 911 GT3 R, a hardcore racer powered by a 4.0-litre flat six and designed to compete in international FIA GT3 race series come 2010. Yes. First there was the GT3, then the more powerful and wider-bodied GT3 RS, and then a Cup race version of that car.

2013 Audi RS6 Avant: 190mph & 0-62mph in 3.9 seconds

The 2013 Audi RS6 Avant has been revealed with a V8 552bhp Twin Scroll Turbo delivering 0-62mph in 3.9 seconds and up to 190mph. The 2013 Audi RS6 Avant comes with a 552bhp version of the twin-scroll V8 found in the latest, most powerful Audis (and the Bentley Continental GT V8) which, despite being 28bhp down on the power of the old V10 RS6 (although it does have 37lb/ft more torque – 516lb/ft) can get to 62mph in a supercar-bashing 3.9 seconds and, in standard guise, 155mph. But spend more than the £77k Audi will want for the new RS6 Avant by opting for the Dynamic Package and top speed increases to 174mph.
