With McLaren still reluctant to disclose the official Nurburgring lap time of their P1 hyper car and the LaFerrari too indifferent to even try it, Koenigsegg One:1 is now stepping in to challenge Porsche 918 Spyder’s record of 6 minutes 57 seconds.

The world’s first Megacar with a power to weight ratio of 1 to 1 is yet to be fully tested by independent journalists, but sources close to the company say Christian von Koenigsegg is very confident the One:1 will accomplish everything he has claimed for it, and then some. He reportedly believes his Megacar will take a “very significant chunk” out of 918’s time.

Koenigsegg One:1 is a monster of a car with a 1,340 horsepower twin-turbo engine and dry weight of 1,340 kg. Only five units of this model will ever be made, so chances are those figures will never be verified by an independent source. But still, the Agera One:1 is undoubtedly one of the fastest cars in the world right now. It is, however, rear-wheel-drive and a lot harder to drive fast than Porsche 918. So we still have our doubts about it smashing the all-wheel-drive 918’s record.

Latest reports from Sweden suggest Koenigsegg is aiming for a Nurburgring lap time in the neighborhood of 6:30.
