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.

2012 Saab 9-3 Convertible: Last 26 RHD cars up for grabs

Saab 9-3 Convertible – Last 26 RHD cars up for grabs The last 26 RHD Saab 9-3 Convertible models – hand finished in Sweden – are now for sale in the UK from £22,750. Back in March – at the same time we reported the Saab Museum had re-opened – we were also able to report that ANA, the Saab dealers in Trollhatten, have bought up the part-made cars left on the Saab production line and were going to finish them off and put them up for sale. Fortunately for UK Saab lovers, 26 of those cars were RHD Saab 9-3 Convertibles - including the very last limited edition Saab 9-3 Independence – and they have now found their way to the UK and are up for grabs.

Mercedes front row in China F1 Grand Prix – Rosberg on pole

Nico Rosberg is on pole position for the Shanghai Grand Prix Nico Rosberg is on pole position for Mercedes in the Chinese Grand Prix in Shanghai with team mate Michael Schumacher alongside. Not only has Nico Rosberg taken pole position at the Chinese Grand Prix in Shanghai, but he did it with one flying lap at the start of final qualifying to take his first F1 pole and Mercedes first since their return to F1 in 2010 after an absence of more than half a century. Rosberg beat second place man Hamilton by a full half second, but Hamilton has a five place penalty for a gearbox change so starts seventh.
