Maserati refreshes Quattroporte

By Ben Whitworth First Official Pictures 24 June 2008 08:51 Maserati has given its Quattroporte a mid-life refresh and a power boost. The new flagship Quattroporte S borrows the 424bhp 4.7-litre V8 from the GranTurismo S, while the standard Quattroporte retains the existing 393bhp 4.2-litre engine from before, with both hooked up to the ZF six-speed automatic transmission introduced two years ago. No, fortunately Maserati has decided not to tamper with the Quattroporte’s styling – five years and 15,000 sales from launch and the Pininfarina-penned saloon still looks superb.

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.
