The Story Of Subaru WRX STI Type RA NBR Special Nurburgring Lap – Video
Le Mans driver Richie Stanaway in the Subaru WRX STI Type RA NBR Special at the famous 12.8-mile Nürburgring Nordschleife race track, achieving a time of 6 : 58. 9.
The WRX STI Type RA NBR Special was designed to show the capabilities of the Subaru sedan and Symmetrical All-Wheel Drive. This time attack car has set lap records at the Isle of Man TT, the Goodwood Festival of Speed hill climb (where it was also 3rd fastest overall) and now it has conquered the 12.8-mile (20.6-kilometer) lap around the Nurburgring Nordschleife in less than seven minutes. Achieving a time of six minutes and 59 seconds, the Prodrive built time attack car is equipped with a rally spec 2.0-liter Boxer engine and Subaru Symmetrical All-Wheel Drive.
The WRX STI Type RA NBR Special is a custom built race car built by Prodrive using a 2017 stock WRX STI with a full roll cage welded into the standard WRX STI unibody for added strength and stiffness. It has a modified 2.0-liter Subaru WRC-spec boxer motor. It uses a 75-mm intake, and the turbo runs at 25 psi of boost. This produces more than 600 horsepower at 8,500 rpm. The car has 9-inch-wide slick tires all around. It uses a WRC gearbox with an automatic clutch, modified with hydraulics for paddle-shift operation. Shift times are some of the fastest at 20 to 25 milliseconds. A redesigned aero-package, different than last year’s TT car set up, delivers improved handling and top speed on the NBR Special. At top speed, the whole package produces about 650 pounds of downforce. The design includes a Drag Reduction System rear wing that is similar to the technology found in Formula 1 cars. With its combined electric and hydraulic operation, the wing can deploy for full downforce/drag under braking or in fast turns and then open for less downforce/drag on long straights. The driver has full control of the DRS via a steering wheel mounted control.
