Subaru built a 4 door monster, with 300 ADDED hp, and took the ring in 6:57:578

Subaru’s Nürburgring beast is now one of the fastest cars around the track thanks to a lot of “optional” extras and the work by rally masters Prodrive. It recorded a ‘Ring time of just 6:58.9.

Subaru was able to accomplish this feat by building the WRX STI Type RA NBR Special, a time attack monster set up for the grueling 12.8-mile circuit. The 2.0-liter four-cylinder turbocharged Boxer engine is up on power—300 extra horsepower to be exact—thanks to a fully built motor from Prodrive and a turbo that runs a staggering 25 psi of boost.

The motor is also able to rev to a preposterous 8,500 rpm redline. The purpose-built race car features a WRX gearbox, heavily redesigned aerodynamics including a rear wing with a drag reduction system, and a full roll cage for added strength and stiffness.
