"Megacar" returns to the 'Ring in search of a fast lap time.

If you’re near the Nürburgring, keep your eyes peeled for the Koenigsegg One:1 shown in this video, which is currently running on the famous track as engineers test the car's mettle.

In this clip, the One:1 sounds absolutely menacing, its engine roaring and whistling as it tackles well-known sections of the Nürburgring. While it’s not clear whether the driver was doing an all-out hot lap, the One:1 certainly was no slouch.

Seeing the car at the ‘Ring has been a long time coming. When Koenigsegg revealed its mighty One:1 back in 2014, it billed the car not as a supercar or hypercar, but as a “Megacar.” The Swedish company hoped to put its ultra-high-performance machine to the test at the Nürburgring, but was foiled when a racing crash resulted in speed limits blanketing the famous track for most of 2015. With the limits lifted earlier this year, Koenigsegg decreed it would return to the Green Hell to set a lap time.

Koenigsegg said in an April 2016 blog post that the company wasn’t necessarily aiming to set a new lap record this year, only that it would spend as much time as possible testing on the German track. The One:1 will test only on private days, not public days, with Koenigsegg factory driver Robert Serwanski at the helm. “Will we gun for a record this year? Maybe,” the company said. “It depends on many, sometimes mundane, factors such as track access/availability, driver availability, the weather and other commitments that may pose a conflict in terms of timing.”

Visually, the Koenigsegg One:1 spotted here looks just like the examples that have graced international auto show stands, with perhaps the most identifying feature being the car’s enormous rear wing that sprouts on dramatic supports from the rear decklid. Five-spoke carbon-fiber wheels, a deep front splitter, and an aggressive rear diffuser add even more visual menace. Beneath the surface, the One:1 uses a 5.0-liter biturbo V8 good for the equivalent of 1,322 horsepower and 1,011 lb-ft of torque, while a seven-speed dual-clutch transmission divvies up power to the rear wheels.

Stay tuned later this year to find out whether Koenigsegg’s test driver did indeed set a new lap record in the wild carbon-fiber machine.
