We've already driven the 2012 Nissan GT-R, but only now has Nissan released official details. Fortunately, we weren't far off with our estimates, as you can see in our first drive report here.
Power from the 3.8-litre twin-turbo V6 has been increased by 20bhp to 542bhp thanks to improved airflow in the engine, while torque has grown by 20Nm to 632Nm. The engine's efficiency has been improved too, with fuel economy rising from 23.5mpg to 24mpg.
At this stage there's still no figures for top speed or CO2 emissions as the car is still undergoing performance testing, but the 0-62mph time has been clocked at 2.7 seconds - three tenths of a second quicker than the 2011 model.
As well as more grunt, the refreshed car has a newly developed asymmetric suspension. This compensates for the weight of the driver by making the front left spring rate firmer, and mounting the rear suspension arms lower on the right than the left.
On the inside, blue lighting on the inner edge of the tachometer brightens up the instrument panel, while a rear view camera is now standard on all models. The Bose sound system has also received an upgrade.
Prices are yet to be confirmed for the UK, but expect a hike in the region of £4,000, bringing the total to £75,950 when the new GT-R MY12 goes on sale in December.
Nissan has also confirmed that a track-focused version of the GT-R is heading for the UK. Further details will be released next month, but it's likely to be called the Club Track Edition and feature slick tyres, a roll cage and adjustable suspension.
