According to Subaru, the WRX STI Type RA NBR Special has set a new lap record for the four-door sedans at the Nüburgring Nordschleife race track with a time of 6:57.5!
There is something to note here, however: the Subaru WRX STI Type RA NBR Special is not a production car – it's pretty obvious just by looking at it. In fact, it was designed to "show the capabilities of the Subaru sedan and all-wheel drive", and features a rally-spec 2,0-litre Boxer engine.
Dominick Infante, the Subaru product communications manager, said that they brought the WRX STI Type RA NBR Special "to set a record and call attention to the WRX STI Type RA that we will launch later this year. The WRX STI Type promises a great deal, with improved performance and styling and even better handling dynamics than the current car".
Courtesy of Prodrive, the car is a custom-built race car, and the 2017 WRX STI was used as a base, with a full roll-cage welded into the standard unibody.
This modified WRC-spec engine features a 75mm intake, while the turbo runs at 25 psi of boost. The result is about 475kW at 8 500 r/min. The car runs on slicks and uses a WRC gearbox with an automatic clutch and is modified with hydraulics for paddle-shift operation.
In addition, there is also a redesigned aero-package that Subaru says will deliver improved handling and top speed!
