Nissan has revealed its heavily updated GT-R is capable of 0-62mph in just 3.0sec, 0.3sec faster than the Porsche 911 Turbo S.
Nissan had previously remained coy on the 11MY GT-R's acceleration capabilities, not confirming any figures alongside the rest of the car's revisions announced shortly after the Paris motor show.
The 3.0sec time was achieved at the Sendai Hi-land Race Way on 12-13 November, achieving the same time at media events on both days. Weather conditions were "sunny/cloudy" for both days, with a temperature of 14.9 degrees celsius on the first day and 18.6c on the second.
A standard Pure Edition car with no options and stock wheels and Dunlop SP Sport tyres was used for the runs, the suspension being set to the extreme 'R' mode.
All 2011 model year GT-Rs get more power and toque, as well as refreshed exterior and interior styling and a new aerodynamic package. Power from its 3.8-litre V6 engine is increased to 523bhp, arriving at 6400rpm. Peak torque is also increased to 451lb ft and is available between 3200-6000rpm. Despite these increases, fuel economy and CO2 emissions are also improved.
Dynamic changes include a new strut brace, revised spring ratios, shock absorbers and stabiliser bars and improved brakes to reduce fade and boost stopping power.Read Autocar's first drive of the new Nissan GT-R
