Nissan has quietly released an updated version of the GT-R at the Tokyo motor show.

Visually the car is virtually identical, although there are now rear diffuser cooling ducts that were previously only available on the Spec-V.

Under the skin the GT-R has tweaked suspension settings to increase comfort slightly while not affecting roadholding, according to Nissan.

The catalysts now have better flow to improve low and mid-range responsiveness. The navigation system has also been updated.

The hardcore Spec-V models receive revised rear shock absorber settings to improve both ride and handling.

Currently the changes are only available for the Japanese market GT-Rs.
