This summer, the Audi RS3 Sedan set a new record for a compact car on the Nurburgring in production form. Today, we want to share the story of a much faster Audi with you, albeit one that has very little to do with the performance sedan from Ingolstadt. Friends, meet what is now considered to be the fastest all-wheel-drive Audi in the world.

The video above was filmed at the Arad International Airport, 2.4 miles (4 kilometers) west of the city of Arad in western Romania, where Konstantin Dinev from Bulgaria set a new record for the fastest Audi AWD with a time of 7.47 seconds on the quarter-mile run and a terminal speed of 188 miles per hour (303 kilometers per hour).

 

Under the hood, this Audi S2 has a 2.2-liter turbocharged inline-five engine fitted with a concrete-filled engine block from a 2.5-liter diesel. The new block helps the five-cylinder unit resist over four bars of boost coming from the massive turbocharger. The result is 1,350 horsepower (993 kilowatts) on the wheels or approximately 1,500 hp (1,103 hp) at the crank.

The power reaches the wheels through a special clutchless Liberty drag transmission working with compressed air to shift the gears. The power flow with this gearbox is never interrupted between gear changes, which allows for extremely consistent output from the engine to the wheels. The car was designed, assembled, and tested by Bulgaria’s Heed Auto team.

Speaking of that, we heard from the folks behind the project that this is the second-fastest Audi in the world overall, being beaten only by a rear-wheel-drive Audi in America doing the quarter-mile in the mid-six seconds. Unfortunately, we weren’t able to find more information about this car to confirm its existence.

As a final note, during the same race in Arad, a 1,000-hp (735-kW) Volkswagen Lupo hit the race semaphore, which was then hit again by a 1,200-hp (883-kW) BMW 3 Series E36. Luckily, no one was hurt in the accident and the semaphore was repaired just in time for the final round of drag races this past weekend. A video from the accident is attached below.
