The folks over at PistonHeads.com headed to Silverstone to catch up with Kazutoshi Mizuno, otherwise known as the father of the GT-R. Mizuno spent some time detailing the improvements the 2012 Nissan GT-R (2013 U.S.-spec model) sports, and how he anticipates it to be a very noticeable difference to the car’s performance.

For 2012, the GT-R will receive a nice increase in power, though no figure has been set in stone. The estimates are to be around 550-hp while the right-hand-drive markets will receive an asymmetric suspension setup. The suspension is designed to counterbalance the extra 110-lbs of the steering assemblies. Minor revisions were also made to the front end, slightly improving steering.

And while all these changes are probably very minor and unnoticeable to the everyday person, Nissan claims that the 2012 car was faster throughout the track at Silverstone and because of that data, Mizuno believes that the 2012 GT-R could be 7-8 seconds faster than the 2011 lap time of 7 minutes and 24 seconds.

To put this into perspective, the current production car Nurburgring record holder is the Viper ACR with a 7:12 time.

There will also be an announcement of a Track Pack for the 2012 GT-R which will include Spec-V style interior, racing seats with high friction fabric, upgraded brakes and a sport exhaust. Mizuno also teased about the possibility of expanding the GT-R model line.

SpecV-Drive-101

After releasing the limited edition Nissan GT-R SpecV (pictured above) last year, rumors of a more comfort-oriented SpecM model have surfaced. Those rumors have now reportedly been confirmed by GT-R project chief Kazutoshi Mizuno, when he ran into the folks from PistonHeads at Nissan’s Nürburgring test facility.

The SpecM edition is geared slightly more towards luxury but is supposed to offer a very close level of performance to the standard GT-R. The philosophy behind this model is to create another limited edition version with more of a bespoke feel, using higher end materials and a premium audio system.

Contrary to previous reports, Mizuno said that the SpecM will not debut at the Tokyo Auto Show later this month, but will be unveiled some time mid way through 2010.

In addition to this info, Mizuno also mentioned a few details about the 2010 GT-R, stating that it would come with an upgraded suspension, the SpecV’s rear diffuser and NACA ducts will be fitted at the rear of the car for better airflow and improve brake cooling.

Possibly the coolest addition, however, is the optional NISMO data-logging setup that will allow owners to download the data from the GT-R’s ECU on a USB stick so they can study it on their home computer or share it with friends.

As we reported yesterday the new GT-R SpecV is now an official reality and today Nissan release a short video of the car testing at the Nürburgring.

According to gtrblog.com staff, who were at the official unveiling of the car at Nissan HQ in Japan and who spoke with Chief Engineer Kazutoshi Mizuno, the SpecV will get an “overboost” function that will deliver added mid-range torque for 80 seconds – ideal for passing on the racetrack.

More information is also available on the SpecV’s carbon ceramic brakes. Not only will the new disks be lighter than stock but they will also be larger measuring 15.35-inches at each corner.

See our original article on the GT-R SpecV for more info and a gallery of photos.
