Subaru captures sedan lap record at Nurburgring.

The WRX STI Type RA NBR is the fast four-door \'round the \'Ring.

Subaru seems to be on a quest to seize records at the world's most famous motorsports venues. After setting records at the Isle of Man and Goodwood Festival of Speed, a Subaru now holds the record for fastest sedan around the famed Nurburgring circuit.

The Subaru WRX STI Type RA NBR clocked a 6:57.5, a time that's merely half a second behind the the $847,000 Porsche 918 Spyder, record holder for the fastest production car. Parsing the mouthful of a name, the WRX STI is the standard model name for Subaru's flagship sports sedan. Type RA stands for "Record Attempt," and of course NBR is an abbreviation of Nurburgring.

Granted, the Subaru isn't a production sedan, but the performance is nevertheless impressive. The WRX STI Type RA NBR was built by long-time Subaru collaborator Prodrive and equipped with what Subaru calls a "rally-spec" version of its 2.0-liter flat-four boxer. Taken from its WRC racers, the engine has been heavily modified to run 25 psi of boost from the turbo, generating about 600 horsepower at 8,500 rpm.

The body was heavily modified as well, with a race cage and an aero package that generates "about 650 pounds of downforce." Prodrive estimated a 179 mph top speed.

Previous sedan records at the Green Hell were held by the Alfa Romeo Giulia Quadrifoglio and Porsche Panamera Turbo. Subaru's effort was done to call attention to the production WRX STI Type RA to be released later this year, said spokesman Dominick Infante. Subaru says it will release a video of the record run shortly.
