BMW Z4 – with 550bhp V10!

Manhart Racing has produced a BMW Z4 with the M5 V10 BMW reckons that there is no need for a Z4M, so the best Bavaria offers off the shelf is just over 300bhp.

Pagani Zonda Revolucion (2013) first pictures of ultimate 790bhp Zonda

Is the new Pagani Zonda Revolucion the Nurburgring lap-record holder in waiting? The Zonda Revolucion (Revolution in Spanish) is a fettled version of the track-only Zonda R, boasting more power and F1-derived brake and aerodynamic know-how. It should easily be able to eclipse the Zonda R's record-breaking 6min 47sec Nürburgring lap time, but you’ll need fast money, too. Available to order now, the five Revolucions being produced will set you back an eye-watering €2.2m (£1.8m) each – plus taxes – and you still can't drive it on the road… For £1.8million, the Pagani Zonda Revolucion had better be packing some serious punch… Worry not: the mid-mounted 6.0-litre AMG V12 (normally aspirated still, rather than twin-turbocharged like the new Pagani Huayra in CAR's video review below) develops 789bhp – a 50bhp increase on the 2009 Zonda R's output.
