It's been causing a stir ever since its launch and is possibly one of the most affordable supercars on the market, but Nissan's GT-R is set to deliver an even better experience for track-focused drivers.

Nissan is offering a new variant called "Track Pack", and unsurprisingly this new version offers a harder edge yet remains fully road legal.

Externally the Track Pack car is easily identified by lightweight six-spoke alloys with gloss black painted centres. The brakes behind these are cooled by additional ducts built into the front bumper. Similar ducts, hidden behind the rear wheels, channel cooling air over the rear discs.

To reflect this GT-R's harder edge, the car's suspension has been revised to be optimal for track use. Like all GT-Rs though, the dampers are adjustable to offer more comfort when the car is being used on the road.

In the cabin, Recaro front seats are trimmed with blue bolsters and an innovative high grip material to help keep the driver in place during hard cornering and braking.

Enhancing the car's harder edge, the rear seats have been removed to save weight. A "Track Pack" emblem on the centre console identifies this model as a special GT-R.

One thing that hasn't changed is the car's engine, which retains the same specification as the `regular' 2012 model GT-R. This means 550 horsepower and a 0-60 mph time of just 2.7 seconds.

The Track Pack adds £10,000 to the £74,450 list price of the standard 2012 GT-R, making it £84,450. Orders for all 2012 GT-R's can now be taken at any one of the 21 Nissan High Performance Centres around the UK. The first deliveries are expected in March 2012.
