Opel/Vauxhall Cascada [w/gallery]

The Opel/Vauxhall Cascada effectively replaces the Astra Twin Top, but attempts to move the model upmarket as a separate product line. It has moved up a size to reflect its prestige aspirations: at 4,697 mm long and 1,840 mm wide, it's longer than an Audi A5. Like many of the latest generation of convertibles, the Cascada ditches a folding solid hardtop in favor of a lighter, more space-efficient and cheaper soft fabric set-up.

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.
