Mercedes’ AMG division unveils new twin-turbo V8

Those obsessed with torque bemoaned Mercedes’ high-revving 6.2-litre V8 when it was launched in 2005, but just as the world has come to accept the naturally aspirated engine, the company has now unveiled a new twin-turbo 5.5-litre V8. Up to 563bhp – which is the same as the SLS AMG – and 663lb ft, which is much more than the 479lb ft the modern-day Gullwing supercar manages. The engine is an all-new 5.5-litre V8 (5461cc to be exact) with direct-injection technology, an aluminium crankcase and two turbochargers.

Nissan GT-R import fears

Nissan's new GT-R costs just £34,400 in Japan - spelling out juicy savings for grey importers in the UK, where the super-coupe is tipped to cost £60,000. Even after the cost of shipping and import duties, that means you could land a Japanese-spec car for around £42-£45k.

BMW M6 Gran Coupe: Price from £97,490 (+ video)

The new BMW M6 Gran Coupe - officially revealed this week – will cost from £97,490 when it goes on sale in May 2013. The M6 Gran Coupe gets the same, very convincing, looks of the regular Gran Coupes, but with added visual butchness thanks to a front spoiler, flared wheelarches, side skirts, rear diffuser and a carbon fibre roof. That promised aggression is reinforced by the M6 Gran Coupe’s powerplant that comes from the M6 and M5 with a 4.4 litre twin turbo V8 delivering 553bhp and 50lb/ft of torque – available from 1,500 to 5,750rpm – which is enough to get the M6 Gran Coupe to 62mph in 4.2 seconds.
