Nissan has unveiled the updated 2010 GT-R lineup at the Tokyo Motor Show.

Set to go on sale early next year, the GT-R features a new CARWINGS HDD-based navigation system and the rear diffuser from GT-R SpecV.

In terms of performance, Nissan has recalibrated the suspension settings "to offer enhanced, premium quality ride comfort, while still providing the driver with a feeling of direct contact with the road surface." To do this, the company stiffened the rear suspension radius rod bushings as well as the front shock absorbers and springs.

The range-topping GT-R SpecV also receives revised rear shock absorber settings as well as new high performance tires from Dunlop (the previous Bridgestone tires will be available as an option).

Finally, "both the Nissan GT-R and GT-R SpecV achieve improved low- and mid-range engine response, thanks to newly adopted hexagonal meshed catalyst cells that reduce ventilation/airflow resistance."

Japanese pricing starts at 8,610,000 yen for the standard GT-R and tops out at 15,750,000 yen for a GT-R SpecV.
