Subaru WRX STI Nurburgring 24 Challenger Spied Track Testing

2014 NBR Challenge endurance racer attacks Laguna Seca

Feb 18, 2014

Subaru WRX STI Nurburgring Challenge Car Details:

  • Subaru's 2014 24 Hours of NBR entry caught testing at Laguna Seca, CA
  • To compete in production car-based SP3T Class
  • Reinforced 350hp 2.0L turbo engine
  • Features include custom carbon body, BBS wheels, Dunlop slicks and Brembo brakes

I'm frickin' spoiled. Last week, I didn't just get a chance to test out the new 2015 Subaru WRX STI on the 2.2-mile, 11-turn road course called Laguna Seca Raceway, but I was fortunate enough to watch practice of Subaru's STI racecar set to compete in the 2014 24 Hours of Nurburgring endurance race.

We would have loved to go for a ride - or drive - in it, but there's only one seat and apparently the team wasn't confident in my driving skills. Needless to say, I was able to snap as many photos of the car as I could while mind molesting every inch of carbon fiber on the car.

This STI will compete in the SP3T class, which is a production-based class. Due to the class restrictions, the 2.5-liter STI motor is too big, so they opted for the 2.0-liter turbo. It's been tuned to 350 horsepower but definitely capable of more. Power is restricted with a 38mm restrictor before the turbo. The 2.0-liter is reinforced with stronger internals and still uses the stock turbo.

Our favorite part is the custom one-off carbon-fiber body kit; basically everything is carbon minus the roof. The new fenders are two inches wider than stock, which helps allow the STI to run the 18x10-inch BBS magnesium wheels and Dunlop slicks. The brakes remain Brembos but the team opted for Endless pads.

Subaru tells us the car has been finished since November and they are getting ready for two 4-hour races at the Nurburgring before the main event in June. While the car is no doubt a monster on track, they tell us it's very easy to drive and comfortable - an important factor when it comes to endurance racing. Of course we'll never know since they wouldn't give me the keys, but we'll take their word for it.
