Nissan's legendary GT-R super coupe traces its lineage back to the Skyline GT-R of 1969. The modest 2.0-litre powerplant in the original Skyline GT-R generated 160 horsepower in a front-engine, rear-wheel-drive layout. Over the decades, the Skyline GT-R grew much larger and developed much more speed and agility. In 2007 the latest version, known simply as the GT-R, made its world debut and has quite simply humbled its more expensive competitors - if not embarrassed them.

In fact, the astonishing prowess of Nissan's super coupe has convinced many enthusiasts to believe that the GT-R is the very best vehicle in its class. For 2012, Nissan has made some significant improvements.

Peak power output from the 3.8-litre twin-turbo V6 engine increases from 530 horsepower (U.S. spec) to 545 horsepower, while peak torque rises from 448 lb-ft to 463 lb-ft (Nissan's press release has the Japanese domestic market numbers at 550 horsepower and 632 nm / 466 lb-ft). The GT-R's fuel economy rating is also improved - stated fuel consumption is down from 12 litres/100 km to 11.8 litres/100 km.

Engine upgrades include better intake efficiency, reduced air flow resistance, improved exhaust valve cooling and a larger air intake duct for the intercooler. Valve control timing, ignition timing and the air mixture ratio have also been improved. The changes make for more power at high revolutions, improved exhaust emissions efficiency, better engine response and better torque at mid and low-speeds.

The GT-R's transmission has also been refined to provide smoother shifting, with a stronger shift fork arm and a firmer bearing on the flywheel housing. Another change includes a switch to R35 Competition Type 2189E differential oil which was developed for competition use.

Structurally, both the rear section of the engine compartment and the dash panel have been reinforced. Nissan says that this translates into more responsive handling and a greater perception of the vehicle's grip on the road.

Interior changes for the latest GT-R are slight but nonetheless welcomed. They include blue lighting on the tachometer ring in the instrument cluster, a standard rear view camera and new Bose Precision Sound System woofers.

The revised GT-R is expected to go on sale in Japan on November 24 as a 2012 model, and  in North America in early 2012 as a 2013 model.
