Updates to the new model are said to include an increase in horsepower, similar to what Nissan did for the 2011 model year. The extra horsepower will come from a number of engine revisions, including a spike in boost levels, as well as changes to the intake and exhaust. Changes to these components are also said to have lowered emission levels.
Other revisions will reportedly include suspension tweaks to keep the already-ridiculously quick Nissan GT-R firmly planted on the ground, as well as slight transmission improvements for smoother and/or quicker shifts.
Externally, the 2013 Nissan GT-R will not have any changes. Only the underbody will be changed for increased airflow and cooling and for increased suction to the ground.
On top of this changes, a ‘Track Edition’ is also planned for the 2013 model year Nissan GT-R. According to the forum, the special version will be made in right-hand drive only and comes with a number of track-inspired features such as slick tyres, as well as carbon fibre panels for weight reduction. Don't get too excited on this as this edition has not been truly confirmed yet.
The current generation R35 Nissan GT-R is expected to be on the market for only a couple of more years. This could be Nissan’s way of going out with a bang.
