BMW 1-Series M Coupe (2011): more details

BMW's readying a pocket-sized M3 for those on a smaller budget: the BMW 1-Series M Coupe. While official information remains scarce on this 2011 pocket rocket, we've grabbed a few more pointers to its performance and stats. Set to be launched in early 2011, the 1-series based M spells a return to more lightweight M cars after the X6 M and its ilk that strained relations with the most fervent M division fans.

Audi RS5 (2010) first official pictures

This is the new Audi RS5, a £60,000 super-coupe with a high-revving 4.2-litre V8 and a 174mph top speed. It's Audi's riposte to the BMW M3, and we'll see it in the metal at next week's 2010 Geneva motor show. Under the bonnet is the same naturally aspirated 4163cc V8 that powered the old RS4 and is currently found in the R8, but Audi’s Quattro GmbH division – responsible for all of Ingolstadt’s RS models – has squeezed an extra 30bhp out of the engine. That means the high-revving, direct-injection 4.2-litre V8 produces 444bhp at 8250rpm, along with 317lb ft from 4000 to 8000rpm.  That power is sent through a seven-speed S-tronic gearbox to all four wheels, and with the Launch Control system engaged it’s enough to propel the 1725kg coupe to 62mph in 4.6 seconds, before powering the RS5 on to its 155mph limiter.
