This is an interesting video for a couple of reasons. The first part has to do with the NSX-GT FR. The story behind the car begins in 2007 when the sanctioning body of the Japanese Grand Touring Car Championship (JGTC) announced a regulation change that would require all of the GT500 class cars to be front engine with rear wheel drive (FR) layout. At the time, Honda was racing with the mid-engine NSX. The NSX was Honda’s halo performance car with the rest of their sports car lineup being front wheel drive. The NSX-GT FR was built by Honda R&D to see how feasible it would be to adapt the NSX chassis to a FR layout. That’s why the nose of the car in the video will look abnormally stretched and it’s cornering attitude will seem a bit odd compared to the rest of the NSX’s you’ve seen. Honda ultimately decided to develop a clean sheet design for an FR chassis, the HSV-010, specifically for competing in JGTC. The NSX-GT FR was thought to have been scrapped, but it turns out it was just put into storage at the Honda R&D facility after it was used for testing in 2007.
The second reason this video is interesting is the re-emergence of the NSX-GT FR. Honda surprised the Japanese press when they randomly showed up at the Twin Rings of Motegi circuit with the car in 2010. It turns out they were testing a Kinetic Energy Recovery System (KERS) by Zytek, the same company that makes the KERS system currently used in Formula 1 racing. Honda R&D was seeing if KERS would be feasible for widespread adoption in the JGTC series. The NSX-GT FR was a natural candidate since it was already available and it wouldn’t give Honda any extra testing time with the HSV that was still being campaigned. If you listen carefully, you can hear the KERS working under braking and the car rolling down pit lane in pure electric mode.
