The Subaru WRX STI Type RA NBR is not only the most suffixed car in histroy, but the fastest four-door around the Nürburgring, with a time of just 6m 57.5s.

In the world of Nürburgring lap times – shadier than a Frank Miller graphic novel – that pegs it at just half a second slower than a Porsche 918 Spyder. Which is a bona-fide hypercar featuring much power at its disposal.

It’s also comfortably quicker than the Lamborghini Aventador SV nutjob (6m 59s). We’re told the time was achieved “using the Nürburgring timing equipment and was officially verified by track officials”.

Don’t believe them? There’s video evidence below, released a few weeks after the record via some in-car footage. It’s interesting to watch for the noises the engine and transmission make, as much as picking out the driver’s lines and observing the G-meter. We love how Subaru’s matched the Eighties-tastic fonts of its road cars with the timing graphics on the vid, too.

Want some background on the car? The Type RA bit stands for ‘Record Attempt’; the sole reason for this car’s existence. We assume the NBR means, well, the Nürburgring. For such an attempt, you won’t be surprised to learn this little Scooby went to market and came back with a lot of rally-infused aggression. And by market, we mean Prodrive, who built the thing.

There’s a roll-cage and a redesigned aero-pack that includes DRS and enables 650lb of downforce – the only currency super-saloons and supercars trade in these days. Then there’s the engine. It’s a modified 2.0-litre turbo boxer, featuring a 75mm intake, 25 PSI of turbo boost, and a modified WRC gearbox with paddle-shifts (20ms fast) running through all-wheel-drive. The net result is in excess of 600bhp. Not bad. Not bad at all.

“We brought the WRX STI Type RA NBR Special here to set a record and call attention to the WRX STI Type RA that we will launch later this year,” explains Subaru comms manager Dominick Infante. Ah yes, there’ll be a production-spec WRX STI Type RA available to purchase, with actual money, later on in the year.

Sadly, that road-car does without the 600bhp of this NBR Special, instead producing somewhere around the 310bhp mark. Should still be a riot, mind.
