Nissan believes its that it’s next Nismo-badged sports car will become “the ultimate GT-R for the road.” Ahead of its unveiling, spy photographers captured the potentially 440kW beast in action at the Nurburgring!Nissan has confirmed that production on the GT-R Nismo is ‘on track’ and we could see it hit showrooms as early as next year after it's predicted unveiling at the 2013 Toyko Motor Show in November.Image galleryNissan GT-R and Nismo chief product specialist, said: "The Nissan GT-R Nismo is the GT-R with which we pursue pure performance. It is for people who search for true performance with pure motorsports flavour. Its development is on schedule, and I can’t wait to see the model introduced into the markets."The existing GT-R’s twin-turbocharged 3.8 V6 engine will remain under the NISMO, however it’s tipped to produce closer to 440kW and have less weight to shift than the current 1699kg sports car.WEIGHT-LOSS PLANDeveloped in partnership with Williams Advanced Engineering, the GT-R will undergo a serious weight loss plant. Carbon-fibred aerodynamic upgrades and a new exhaust system will be added, with extensive use of carbon-fibred interior panels lower the weight.Already claiming 0-100km/h in 2.7 seconds in standard guise, the GT-R Nismo could reach the rocket to 100km/h in a mere two seconds. If realised, it would be enough to see the Nismo beast become the fastest-accelerating production car yet, even trumping the Bugatti Veyron (0-100km/h - 2.46 seconds).Confirmed to start production in 2014, the flagship of the Nismo model range, which will include a 370Z Nismo and Juke Nismo, will, according to Nissan, become “the ultimate GT-R for the road”.
