The race car is scheduled to compete in the SP3T class, which is a sub-category that only allows cars carrying turbocharged engines with displacements of 2.0 liters or less.
That’s all fine and dandy for Subaru and its new WRX STI NBR Challenge, which is a full-fledged race car complete with all the bells and whistles required to compete in the series. With this being a race-tuned rig, you won’t find the usual WRX goodies; instead, it comes with modified bumpers, a prominent rear wing, a ventilated hood, lightweight windows and a track-tuned suspension, all put in specifically for racing purposes.
The WRX STI NBR Challenge also received a set of 18-inch, BBS wheels wrapped in Dunlop tires, as well as a reworked 2.0-liter, turbocharged engine that’s now capable of hitting 340 horsepower and 340 pound-feet of torque. That’s a tidy 35 horsepower and 50 pound-feet of torque more than the stock 2015 WRX STI.
Subaru has high hopes for the WRX STI NBR Challenge as it prepares to tackle the Nurburgring. Tackling the `Ring is easier said than done, but with drivers Toshihiro Yoshida, Kota Sasaki, Carlo van Dam and Marcel Lasée all ready to take their turn racing this blue rocket, Subaru’s got as good a chance as any other team.

When compared to the base WRX, the new STI adds a more aggressive exterior look with unique doors, fenders, bumpers and hood.
The 2015 WRX STI is powered by a turbocharged 2.5-liter, boxer engine that delivers 305 horsepower and 290 pound-feet of torque, and mates to a bespoke six-speed manual gearbox.
The WRX STI is built on a stiffer chassis for even greater agility and precision. The new model also adds lots of new features, like Active Torque Vectoring, Multi-Mode Driver Controlled Center Differential (DCCD) and Brembo Brakes.

STI to set out to regain the SP3T class victory with new SUBARU WRX STI ‘STI NBR CHALLENGE 2014’
Subaru Tecnica International Inc. (STI) today announced that they will enter their newly released SUBARU WRX STI in this year’s Nürburgring 24-Hour Race (NBR) -42.ADAC Zurich 24H Rennen. The event will take place from 19 to 22 June in Germany with STI aiming for their 3rd win following 2011 and 2012 in the SP3T - a class for turbo-charged cars with an engine of 2 litres or less. The purpose of STI’s participation in this race is to both enhance a ‘flexible yet elegant driving feel’ - a concept that STI lives by, and also to demonstrate the ‘Enjoyment & Peace of Mind’ of driving SUBARU cars in the race for SUBARU fans around the world.
The competition vehicle for this race is based on the new SUBARU WRX STI, whose potential has been enhanced, and incorporates aspects for endurance races. At the same time it uses many technologies for production vehicles based on STI’s experience of participating in the race for 6 consecutive years. Also, through cooperation with Fuji Heavy Industries, starting from the development phase, this vehicle has become even more competitive than the 2013 version because of its improved aerodynamic performance and lower centre of gravity. The team will compete in 2 races of the VLN endurance series at Nürburgring on Saturday 12 April and Saturday 17 May. The aim is to further work on car setups before it appears in the official qualifying on the Thursday and Friday of race week. The 24-hour race takes place from Saturday 21 to Sunday 22 June.
The WRX STI NBR CHALLENGE will be driven by Nürburgring veteran Toshihiro Yoshida, Kota Sasaki, who will be competing in the NBR for the 4th time this year, Carlo van Dam from the Netherlands and Marcel Lasée from Germany who joined the team last year. Team Manager Masahiro Ozawa, Manager of STI’s Power Unit Engineering Department, will take command of the team. Following last year, Hideharu Tatsumi, Deputy General Manager of STI Motorsport Project Office, who has been in charge of development of the car, will act as STI General Team Manager.
The NBR CHALLENGE team will also be joined by 6 SUBARU dealer mechanics -Masaki Ageishi (Nigata SUBARU), Ryosuke Nakamura (Fuji SUBARU), Shinya Kiyama (Osaka SUBARU), Hiroshi Ota (Kyoto SUBARU), Nobuaki Shimazaki (Hyogo SUBARU) and Tatsushi Umemura (Higashi Shikoku SUBARU). These men will be in charge of pit work and vehicle service while utilising their skills and expertise gained through their day-to-day careers as service mechanics.
