McLaren 12C GT Sprint fills the gap between the 12C & GT3

McLaren 12C GT Sprint (pictured) debuts at Goodwood FoS McLaren has revealed a track car that’s not quite as focused as the 12C GT3 or the Can Am, but a bit more focused than a regular road-going 12C – the McLaren 12C GT Sprint. Built by McLaren’s race car division, the GT Sprint gets the same 616bhp and seven-speed twin clutch gearbox as the regular 12C but with new oil and cooling systems and a new radiator at the front borrowed from the GT3 car, McLaren has had a play with the suspension on the 12C GT Sprint, lowered it by 40mm and fitted racing slicks to make the Sprint a lot firmer and sharper than its road-going sibling. Cosmetically, the GT Sprint gets a new front bumper, a bonnet that looks like it came of the 12C GT3, bigger air ducts and wing louvres and the option of lightweight bodywork and a carbon fibre rear wing to push the price up if you want to spend more.

Porsche Boxster (2012) first official pictures

Porsche only pulled the covers off the new 911 Cabriolet at the 2012 Detroit motor show three days ago, but it’s already unveiling another convertible: the new Porsche Boxster. Faster, lighter, cleaner, more economical, and (most importantly) better looking than its predecessor, it will be officially revealed at the Geneva motor show in March, before going on sale in the UK on 28 April 2012. Let’s start with the new Porsche Boxster’s looks then… It’s still recognisably a Boxster, but the headlights are now more vertically stacked, the doors are scalloped to flow into the bigger side intakes, a strong crease runs between the tail lamps and integrates with the pop-up rear spoiler, and every line and angle is just a little bit sharper and more dynamic.  The Porschephiles amongst you would have also spotted that the folding fabric roof no longer has a panel to drop behind; instead the roof itself now doubles as the cover when the hood is stowed.

Wild thing: Audi A1 clubsport quattro unveiled

Audi has created a 496-hp version of the A1 small car to celebrate the 30th anniversary of an Austrian festival for Audi, Seat, Skoda and Volkswagen fans. Called the A1 clubsport quattro, the one-off show car gains a heavy dose of rally-inspired styling that is said to preview the appearance of a hot new all-wheel-drive S1 quattro model being developed by Audi as a rival to the likes of the Renault Clio Sport. At the heart of the hatchback is a heavily modified version of Audi's turbocharged 2.5-liter, five-cylinder powerplant shoehorned transversely into the A1's compact engine bay.
