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.

Mercedes S63 and S65 AMG debut at Shanghai

Mercedes revealed the S63 and S65 AMG (pictured) at the Shanghai Motor Show today In yet another demonstration of how important emerging car markets are to premium car makers, Mercedes has chosen to unveil its top two S Class models – the Mercedes S63 AMG and the Mercedes S65 AMG - at the Shanghai Motor Show today. These range-topping S Class Mercedes get the same updates as the lesser siblings (and the Hybrid S400) we told you about a week ago. But this isn’t a new model – just a mid-cycle refresh of the S Class in general.

Used car market pressure eases

AN INCREASE in the number of used cars coming into the market has “taken the edge off prices” and calmed some corners of the industry, according to used car pricing experts CAP. A greater influx of part-exchange cars arriving at dealers is partly responsible, and with many franchised dealers focusing for the time being on selling those vehicles, competition to acquire stock on the open market has decreased. CAP reports that the pressure has been lifted on some dealers who had become frustrated at how expensive it was becoming to source cars at fair prices.
