SUBARU / STI to Compete in the Nürburgring 24-Hour Race 2024
Subaru Tecnica International *1, SUBARU's motorsport subsidiary, will participate in 52nd Nürburgring 24-Hour Race on 1 and 2 June 2024 at the Nürburgring circuit in Germany with its latest race car based on the WRX. This is the 17th year of their challenge in the event since 2008.
The SUBARU WRX NBR CHALLENGE 2024 will be powered by a new 2.4-liter direct-injection turbo engine and will compete in the SP4T class, where turbocharged cars between 2.0 and 2.6 liters are entered.
The team will be aiming for a class win and top overall ranking with car number 88, following the perfect win in 2019 , and also the number considered auspicious in Japan.
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, the race car has been developed with the SGP (Subaru Global Platform) at its core, while taking advantage of the basic layout of the horizontally opposed engine and symmetrical AWD.
