The One is number one.
Mercedes-AMG's new Formula 1-based supercar has claimed the production car record at Germany's Nurburgring Nordschleife track.
The winding, rough and nearly 13-mile long circuit is used by automakers as a benchmark for the real-world performance of their sports cars.
The $2.7 million One lapped the damp track in 6 minutes, 35.183 seconds, which beat the old record held by a Porsche 911 GT2 RS by 8 seconds.

"I didn’t expect that we would be able to set such a lap time with these track conditions. In some crucial areas of the track, it hadn’t dried completely yet and was therefore tricky."
The One looks like a Le Mans racer, but is powered by a version of the Mercedes-AMG Formula One car's 1.6-liter V6-based hybrid powertrain.
