The Subaru WRX STI Type RA NBR Special recently set a new lap record for a four-door sedan at the 12.8-mile Nürburgring Nordschleife race track, achieving a time of 6:57.5. The special WRX STI was driven by Richie Stanaway and now Subaru has released a video of the record setting lap.
Subaru says that the WRX STI Type RA NBR Special was designed to showcase the capabilities of the Subaru WRX STI’s all-wheel drive system and draw attention to the upcoming release of the production WRX STI Type RA. The WRX STI Type RA NBR Special has set lap records at the Isle of Man TT and the Goodwood Festival of Speed hill climb.
The Subaru WRX STI Type RA NBR Special is a Prodrive-built time attack car based on a standard 2017 WRX STI with a full roll cage welded into the standard WRX STI unibody. Under the hood it’s powered by a modified 2.0-liter Subaru WRC-spec boxer motor and Subaru Symmetrical All-Wheel Drive. The boxer engines uses uses a 75-mm intake, and the turbo runs at 25 psi of boost to give it more than 600 horsepower at 8,500 rpm. It uses a WRC gearbox with an automatic clutch, modified with hydraulics for paddle-shift operation – dropping shift times to 20 to 25 milliseconds.
It reached a top speed of 179 mph at 8,500 rpm in top gear at the “Ring”. The car also features 9-inch-wide slick tires all around. A redesigned aero-package delivers improved handling and top speed on the NBR Special. At top speed the whole package produces about 650 pounds of downforce.
