The first production Koenigsegg One:1 has arrived in Germany and has caused a computer glitch in the country’s car registration system.

The Swedish megacar has exactly 1,341 HP which is the equivalent of one megawatt or exactly 1,000 kW, while Germany’s registration system only accepts vehicles with kilowatts in the three figure range. The One:1 wasn’t able to be registered until the system was updated by software mechanics to accommodate the power figures.

We remind you that one of the fastest cars these days has a 5.0-liter V8 twin-turbo engine from the Agera R which has been upgraded to 1,341 HP (1,000 kW) and 1,371 Nm (1,011 lb-ft). When it was revealed during the Geneva Motor Show back in March this year, the car was described as the “world's fastest homologated production car” with a simulated top speed of more than 440 km/h (273 mph).

Only six examples of the One:1 will be made and all of them have already been sold.
