Going after a world record can be daunting, especially if you are the record holder. Back in 2017, the Agera RS ran 0-400 kph-0 in 33.29 seconds. To put that into perspective, 400 kph is 249 mph. This is a speed only a handful can reach, especially in such a short time. We figured that record would last for at least a decade, but the Koenigsegg Regera just set a new record for 0-400 kph-0.
On Monday, factory test driver Sonny Persson strapped into a new Koenigsegg Regera. Normally, runs like this are handicapped by the transmission, the Regera doesn’t have one. You notice the exhaust sound doesn’t change much at low speeds because the twin-turbo V8 is coupled to a generator. The voltage it makes is sent to electric motors on the rear axles.
Somewhere around 80 mph, a torque converter inside the generator closes its clutch, sending engine power directly to a 2.73 rear differential. It is at this point that the battery (supplied by Rimac) sends power to the generator, making it the 3rd onboard electric motor. This hybrid system is known as KDD (Koenigsegg Direct Drive), and it provides 697 horsepower & 664 lb-ft of torque. The twin-turbo V8 constantly makes 1,280 horsepower and 944 lb-ft of torque.
So what does a car do with 1,479 horsepower and 1,475 lb-ft? It reached 250 mph in 23.65 seconds, and back to 0 in 8.83. This is 1.3 seconds faster than the Agera RS. The official 0-400 kph-0 record now stands at 31.49 seconds. For comparison, the Bugatti Chiron does this in 42 seconds… Congrats to the team for this blistering run.
