After accidentally setting a new production-car lap record at the Suzuka circuit 
in Japan, the 2015 Koenigsegg One:1 “megacar” continues to do extraordinary things. The latest was setting a new 0-300-0-km/h (0-186-0-mph) record of an incredible 17.95 seconds, and lucky for us, the whole thing was caught on video.
The attempt took place at Koenigsegg’s vast factory test track, a disused runway originally built for the Swedish Air Force. The One:1 was fitted with a Vbox system for science, and some well-executed donuts were done to get some heat in the rear tires. Then, Koenigsegg test driver Robert Serwanski punches the throttle, and the thing is off the line like a scalded car. It only takes the 1,340-horsepower Koenigsegg 11.92 seconds to knock-off 0-300 km/h, while getting back to zero takes just 6.03 seconds. With deceleration like that it’s a wonder Serwanski’s eyes are still attached to his skull.
Oh, and just to make things fun, he made most of the run with his hands off the wheel.
“Look Ma… no hands!”
This was actually a practice run. Representatives from the Guinness Book of World Records will be on hand for the real thing, when it (in all likelihood) officially breaks Koenigsegg’s own record of 21.19 seconds set by a the 2011 Koenigsegg Agera R in 2011. That’s a massive 3.24-second improvement over the Agera R, which, with 1,115 horsepower, isn’t what you would call slow.
Koenigsegg calls the One:1 a “megacar” because is produces the equivalent of one megawatt, which, as previously mentioned, is 1,340 horsepower. It also weighs 1,340 kg (2,954 pounds). That’s one horsepower per kilogram, hence One:1. If Serwanski were to keep his foot on the throttle past 186 mph (and had a runway long enough) the One:1 would accelerate to its theoretical top speed of 400 km/h (248 mph) in just 20 seconds.
The One:1 will be heading to the Nürburgring Nordschleife soon to attempt a production lap record. That should be an incredible thing to witness, so stay tuned.
