Subaru Tecnica International( *1), SUBARU's motorsport subsidiary, will participate in the qualifiers on May 7 and 8 and the 50th Nürburgring 24-Hour Race from 26 to 29 May 2022 at the Nürburgring circuit in the Eifel region of Rhineland-Palatinate, Germany with its WRX STI-based race car. This is the 15th year(*2) of its challenge in the event since 2008, and the first race in three years.
This year, the SUBARU WRX STI NBR CHALLENGE 2022 will again compete in the SP3T class for cars with turbocharged engines of up to 2 liters displacement, aiming for its seventh win in this class.
The track is said to be the toughest in the world with a total length of 25km, a 300m difference in elevation and ever-changing weather conditions. In order for drivers to drive fast and control the car as they wish on such a challenging track, while taking advantage of the basic layout of the horizontally opposed engine and symmetrical AWD, the following performances of the car have been enhanced since last year.
【Main Areas of Improvement in the SUBARU WRX STI NBR CHALLENGE 2022】
① Larger tires from 260/660R18 to 280/680R18 to enhance grip and driving stability
② Larger wheels from 10J to 11J to optimize the rigidity
③ Increase in the fuel tank volume from 100L to 110L and optimized fuel control to maintain the nine-lap strategy and to aim for the maximum 10 laps
④ Optimized set-up for a vehicle weight of 1300kg
⑤ Introduction of a collision avoidance warning system
⑥ Improvement in the level of telemetry communication
⑦ Reduction in the burden on drivers with the introduction of electric power steering

The participation of dealership service technicians in overseas motor races has been ongoing since 1990, with the aim of delivering “peace of mind” and “pleasure of driving” in customers’ car life by improving the technicians' technical skills. To date (until 2019), 377 service technicians have worked on the Safari Rally, the WRC(*3) and the Nürburgring 24-Hour Race.
