For a start, Nissan has given more boost to the GT-R whilst also fine tuning the valve timing and air mixture ratio. The inlet pipe diameter is now larger (which means less air resistance) and Nissan has fitted a redesigned exhaust pipe. That means fuel economy has improved by 0.5L/100km (now at 12L/100km). Seriously though, we don't really care about how much greener it is, if you want a green Nissan go buy a LEAF.
The car has lost a good 10kg and now has 390kW(523hp) at 6,400rpm and 612Nm of torque from 3,200 to 6,000 rpm. That's 33kW and 24Nm more power and torque than the 2010 Nissan GT-R.
Additional changes include a 2WD mode for when starting the vehicle while turning the steering wheel (e.g. getting out of a car park). The 2WD mode only works for speeds below 10km/h and when the steering wheel is turned more than half way. So it's not going to suddenly begin drifting around corners. Nissan says it has also changed the way the transmission behaves when the car is started in R Mode.
Number of body strengthening features have been added to better improve the car's handling and dynamics. Most notably a lightweight carbon composite (with aluminum honeycomb material) strut supporting bar has been added to the partition wall of the engine compartment and an additional support member makes its way into the passenger side of the instrument panel. Nissan says the changes allow the new 2011 GT-R to better receive suspension input and therefore provide improved road feel.
Body panels are also fitted with even more accuracy thanks to a higher-precision G sensor being used during vibration testing for each GT-R body.
Front suspension's shock absorbers, stabilizer bar and lever ratio of the springs has been retuned for better vertical load response of the tyres. Meanwhile front caster angle has gone up from 5°35 to 6°00, which Nissan claims will help improve trye road holding ability when turning and stability while driving straight. The rear gains minor changes with the roll center height being lowered for better cornering grip.
The GT-R's brakes have also been upgraded thanks to a new and thin 390mm rotor developed by Nissan for better braking force and fade resistance. The car's new bumper also allows more air to pass through to cool the brakes.
From the outside the easiest change to spot is the new "Hyper Blue Black Chrome" Nissan GT-R wheels which are now lighter and more rigid. The wheels are made by Rays and undergo a five-layer coating process to gain their deep gloss look. More Knurling inside the wheel has taken place to avoid deviation of tyre rotation direction caused by the higher engine output. The wheels are wrapped in Dunlop SP SPORT MAXX GT 600 DSST CTT tyres which make use of a new stickier compound.
Thanks to a redesigned front and rear bumper and other minor aerodynamic changes, Nissan has been able to increase downforce by about 10 percent front and rear, while the coefficient of drag is now 0.26 (previous 0.27).
From the front, the new bumper makes use of double rectifier fins and "Hyper Daylight" as well as large-diameter reflecting surface and high intensity white-color LED lights. The rear bumper allows for a lower centre of gravity whilst an extended rear diffuser helps improve cooling. A new standard features is high intensity LED fog lamps for the rear.
Moving inside the 2011 Nissan GT-R cabin, one will easily spot the new shaped seats which provide more side-support for better cornering feel. Nissan has also updated the instrument panel pad and navigation system display. A new carbon centre cluster finisher is used and all the switches are now matte black. The GT-R logo on the steering wheel also sports a new velour-like coating whilst the attached paddle shifters make use of a new coating exposing the magnesium base material.
Other minor interior details include the now 'black smoky coated' chrome-plated rings in the console and air-conditioner outlets.
Nissan has not said whether or not the improved power and torque means a faster 0-100km/h time, nonetheless we are sure many enthusiasts will put the previous and upcoming model side by side for a drag race.
The 2011 Nissan GT-R will be available with two new colours, Jet Black and GT Blue.
