Pagani Zonda Cinque Roadster (2009): first official pictures

By Ben Pulman First Official Pictures 03 July 2009 16:30 Pagani has unveiled a roadster version of its most radical road-legal Zonda ever, the Cinque. Just five Cinque Roadsters will be made, and with no roof, a 669bhp V12 engine, and a price tag broaching £1.1m (plus taxes) it's pretty special. Think again - and if Horacio Pagani wants to build 5 more gorgeous Cinques, this time without a roof so you can really hear that 7.3-litre V12 wail, then who are we to argue. There's a longer front spoiler, a flat undertray and diffuser, plus a new rear wing, all of which is enough to create the same 750kg of downforce at 186mph that Pagani claims for the coupe version.

2012 Mercedes SL – the aluminium supercar

2012 Mercedes SL - it's got a lot of aluminium It’s perhaps a step too far to describe the 2012 Mercedes SL as an aluminium supercar, but there is no doubt the 2012 SL will be a super car, and that it gets made from aluminium instead of steel. And the 2012 SL 63 AMG will undoubtedly be in the supercar league. Just like Jaguar, Mercedes sees the liberal use of aluminium as a cost-effective way to make its cars both lighter and more rigid.

Stress and strife of the school run

SCHOOL RUN WARS are rife, with parents prepared to squabble over parking spaces and argue with their children, according to a survey. As many as 23% of mothers and fathers admitted blocking another parent in with their vehicle and 14% owned up to cutting someone up, the poll of more than 3,000 motorists by Auto Trader showed. Also, 16% of parents have argued with other mothers and fathers on the school run and 53% have had rows with their children.
