Chevrolet sprinkles in some ZR1 for the Corvette Z06 Carbon Limited Edition

With the ZR1 grabbing all the headlines of late, it's easy to forget about the other pumped-up performance thoroughbred in the Corvette stable--the Z06. However, that's about to change, because Chevrolet is taking some of the ZR1 goodies and transplanting them over onto the Z06 for the 2011 model year, such as the Brembo carbon-ceramic brakes and magnetic select ride control system. The features will be standard on a new 2011 Corvette Z06 Carbon Limited Edition, which Chevy is using to celebrate the 50th anniversary of the Corvette's first 24 Hours of LeMans race.

Audi Q3: new entry-level 1.4 TFSI & new S Line Plus trim option

The new Audi Q3 1.4 TFSI (pictured) offers a sensible petrol alternative Although we all now seem as obsessed in the UK by frugal diesel engines as Europe has been for many years, there’s a lot to be said for a petrol engine.

The Q3 1.4 TFSI only comes with front wheel drive, but it does offer a sensible alternative to the 2.0 litre TDI 140 for many buyers, with 148bhp, a 0-62mph of 9.2 seconds (8.9s with the optional S tronic ‘box), official economy of 47.9mpg and emissions of 137g/km.
