Video: Koenigsegg Regera hypercar reclaims 0-400-0 km/h speed record

The Koenigsegg Regera – a twin-turbo V8-powered hybrid supercar from a niche manufacturer in Sweden – has unofficially reclaimed the production car record for the fastest time to accelerate from zero to 400km/h and back to a stop again.

In a video uploaded to YouTube, Koenigsegg showed off the claimed record-breaking run, which saw the Regera go from stationary to 400km/h to a full stop in 28.81 seconds.

The Swedish hypercar company claims the run beat the existing record – set last month by the Rimac Nevera electric car – by just 1.12 seconds, while the Regera topped its previous record time from 2019 by 2.68 seconds.

To reclaim the record from Rimac, the Swedish firm fitted the Regera with stickier Michelin Cup 2 R tyres and made its attempt on a smoother runway, allowing the driver to keep their foot to the floor for longer.

Koenigsegg’s video also included a run-down of the key figures from the test, which included a 0-400km/h time of just 20.68 seconds, while slowing down from 400km/h to a standstill took only 8.13 seconds – all in the space of 2061 metres.

The Koenigsegg Regera is powered by a twin-turbo, 5.0-litre V8 engine – producing up to 820kW and 1250Nm by itself – which is mated to a hybrid system with three electric motors.

A pair of 180kW electric motors power each rear wheel while the third is mounted on the engine’s crankshaft, providing up to 160kW of additional power – combining for a total system output of 1119kW.

The Regera sends its power to the rear wheels through a unique ‘direct drive’ unit, which has just one speed rather than a traditional multi-ratio transmission. 

Despite being about 300kW down on the Rimac Nevera’s peak outputs – and without all-wheel-drive – the Koenigsegg Regera is close to 700kg lighter than the electric hypercar, a factor which played a major role in it reclaiming the record.
