The world’s fastest production car on (Guiness) record – the Bugatti Veyron Super Sport – produces 1,183 horsepower and weighs more than 4,000 pounds.

Now take the Bugatti, crank up the horsepower, lower its weight and you have the all-new Koenigsegg One:1.

The Swedish manufacturer calls its newest invention the world’s first production ‘megacar’ because of its 1,000-kilowatt power rating, which converts to approximately 1,340 horsepower. Equally impressive is that the Koenigsegg machine carries a 1:1 power-to-weight ratio – hence the ‘One:1′ branding – meaning the car weighs in at just 1,340 kilograms (2,954 pounds).

This is all achieved through a twin-turbocharged 5.0-liter V-8 on top of a lightweight carbon fiber chassis and body. Hammer through the seven-speed dual-clutch gearbox and you’ll be rocketing from 0-248 mph in just 20 seconds.

Unbelievable, right? Well it’s one thing to see it on paper (or a screen) and it’s another to see it in action. Car guru Shmee150 headed to an abandoned airstrip in Sweden to get an up-close look at the monstrous One:1. Check this out:
