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.

BMW M550d xDrive (2012) - the diesel M saloon

BMW has launched its first diesel M car: the new M550d xDrive in saloon and Touring estate forms. It's part of a strategy to fill the gap between the exclusive M GmbH division cars and the top-end cosmetic M Sport trim lines with a new range of M lite: BMW M Performance Automobiles. Developed by the engineers responsible for the M3, M5 et al, the new M550d xDrive is powered by a new high-output version of the 3.0-litre straight six turbodiesel packing not one, not two, but three turbochargers.

Jaguar plots new flagship coupe as XK bows out (2014)
