BMW M3 engine shown

By Ben Barry Motor Industry 23 March 2007 01:18 BMW has revealed detailed specs on the all-new 4.0-litre V8 that’s soon to be slotted into the all-new M3. Power is confirmed at 420bhp with 295lb ft peak torque available from 3000 to 7000rpm. The engine – made at the same foundry as the BMW Sauber F1 team’s V8 and derived from the same architecture as the M5 and M6 V10 – looks set to dispel any fears M purists may have had that the M3 would be transformed into a nose heavy, slow revving behemoth.

2011 Audi R8 GT, an AW first look

Three years after it burst onto the supercar scene, Audi has unveiled a hard-core version of its R8 called the GT. Based on the existing mid-engine R8 V10 and incorporating aerodynamic, weight-saving and mechanical developments used by the company's R8 LMS GT3 race car, Ingolstadt will build just 333 copies of the new 560-hp four-wheel-drive performance flagship. Pricing has not yet been revealed, but given the extent of the changes to the new two-seater, buyers should expect a hefty premium over the R8 V10's $147,000 price tag when the GT goes on sale in North America.

McLaren P1 gets an Arctic shakedown (+video)

So McLaren are busy throwing the worst conditions they can at the P1 to make sure it can perform even in the harshest of conditions and be the best driver’s car in the world – even when there’s several feet of ice under its wheels. McLaren has had several XP prototypes of the P1 running round the world’s harshest climates – hot and cold – and have delivered a video of the P1 prototype playing on the ice in the north of Sweden – inside the Arctic Circle – to keep interest in the P1 bubbling along ahead of its dynamic debut in the UK at the Goodwood Festival of Speed in July. Despite its enormous power – 903bhp from a combination of its turbo 3.8 litre V8 and electric motor – the P1 does look composed and capable, even with sub-zero temperatures and a surface that has zero grip.
