Nearly two years ago, Koenigsegg managed to set a new 0-400-0 km/h world record when an Agera RS accomplished the feat in a blistering 33.29 seconds. Well, you can now forget about that because the Swedish carmaker has now broken its own record with a Regera, completing the run in just 31.49 seconds. That is 1.8 seconds quicker than the Agera RS, and a full 10.47 seconds faster than the Bugatti Chiron.

As a recap, the Regera features a 5.0 litre twin-turbo V8 and three electric motors – one on each rear wheel providing direct electric drive, and another on the crankshaft for torque-fill – giving it a total system output of 1,500 PS (1,479 hp) and 2,000 Nm of torque.

What makes the car unique is use of the patent-pending Koenigsegg Direct Drive (KDD) instead of a conventional multi-gear transmission, which sees a direct drive to the car’s rear axle from the combustion engine. In operation, the electric motors handle propulsion at speeds of less than 48 km/h, with the internal combustion engine only kicking into action beyond that.

“This was a good opportunity to showcase the true capability of the Regera’s one-of-a-kind Direct Drive transmission. As the Regera only has one gear we had to make use of it from standstill to the record top speed of 403 km/h (or 250 mph) limited by rpm,” said CEO and founder Christian von Koenigsegg.

The record attempt was conducted at the Råda airfield close to the town of Lidköping, although the company states, “as this runway is normally unused and dormant, the surface was not great for traction. Furthermore, it was not possible to drive in a straight line, as some bumps had to be avoided.”

Despite the less than ideal conditions, the Regera only took 22.87 seconds to accelerate to 400 km/h over 1613.2 metres. Deceleration to a controlled stop took 8.62 seconds over distance of 435.26 metres, and the total distance used for 0-400-0 km/h run was 2048.46 metres. The company noted that given better conditions, the feat could be completed in under 2,000 metres.

“What is really impressive is how incredible the Regera brakes – 8.62 seconds from 400 km/h to 0 km/h is just unheard of. It is a testament to the Regera’s balance, suspension, aerodynamics and of course its in-house design and built Koenigsegg brake callipers. The proven numbers now show the greatness of the Regera. Having said that, we know we can improve these already impressive numbers on a track with better conditions,” said Koenigsegg.

The person responsible for the attempt was company test driver Sonny Persson, and performance data for the run was captured using an AiM EVO5 data logger and AiM GPS08 together with a Racelogic VBOX 3i.
