Aston Martin Sale: Mahindra & Investindustrial front runners

It seems the battle to take a stake in Aston Martin has come down to a battle between Mahindra & Mahindra and Investindustrial. After reporting more than a year ago that Aston Martin urgently needed a new owner, or major investor, if it is to survive, it became clear earlier this month that Aston Martin was ready to acknowledge that need as the Kuwait Investment Dar starting seeking a buyer for the majority of its majority stake in AML. So far we’ve had Mahindra and Mahindra, Tata (owners of Jaguar Land Rover), Toyota and unnamed Chinese investors in the frame, but it seems the race to take a big chunk of Aston Martin Lagonda has come down to just two – Mahindra and Investindustrial.

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 Mercedes S Class to spawn a convertible

The n2012 Mercedes S Class will lose its top It’s probably a sign of increasing decrepitude as it seems only five minutes since Mercedes launched the current S Class, but already we’re talking about the 2012 Mercedes S Class – and it’s only a year away. As has always been the case with a new S-Class we can look forward to a raft of new innovations when the new S Class launches late next year; clever stuff that will eventually filter down to the cars of lesser mortals as the technology matures and the cost falls. And that clever stuff will be packaged up in a big saloon car – the normal S-Class – an even bigger car – the LWB S-Class – and a huge two door coupe – the Mercedes CL, which is expected to be renamed the S-Class Coupe when the new S-Class launches.
