The Subaru STI WRX Type RA NBR Special set a new record for a four-door sedan on the legendary 20,6-kilometer Nürburgring with a time of 6 minutes 57,5 seconds. The time was timed and certified using the measurement equipment of the circuit itself and verified by official personnel.
The WRX STI Type RA NBR Special is a design developed as a showcase for Subaru's sedan and its AWD technology. The time-eater has set multiple records on both the Isle of Man and the mountain climb at the Goodwood Festival of Speed, and has now conquered Green Hell by shooting in under 7 minutes.
The WRX STI Type RA NBR Special is a racing vehicle customized by Prodrive, based on a 2017 WRX STI as standard, with a welded inner roll cage to increase its rigidity.
It is powered by a 2.0-liter Subaru WRC boxer engine that was modified and optimized. The air intake reaches 75mm, with a turbo that offers up to 25psi. All of this produces more than 600hp at 8.500rpm. Prodrive calculated a top speed on the circuit of 288km / h at 8.500rpm in its highest gear. The vehicle is fitted with 9-inch slick tires. It uses a WRX automatic gearbox, modified for the use of paddles. The speed of the gear changes are some of the fastest, with times of 20 to 25 milliseconds.
It incorporates a new and redesigned aerodynamic pack that offers the NBR Special improved maneuverability and increased speed. At full speed the complete package offers a downforce of 294kg. The design also incorporates an electrically and hydraulically actuated spoiler, which can be fully retracted or extended depending on whether you want to increase or decrease downforce when cornering or straightening. The driver has full control of the spoiler via buttons on the steering wheel that allow him to change his position completely in just 20 milliseconds.[sam_pro id = 0_1 codes = ”true”]
