On June 16, 2023, the Koenigsegg Regera reclaimed one of the automotive world’s most demanding performance records by accelerating from a standstill to 400 km/h, or approximately 249 mph, and returning to a complete stop in just 28.81 seconds. The achievement established a new 0–400–0 km/h record for a homologated production car, meaning the vehicle was based on a road-legal model approved for customer use rather than a purpose-built racing prototype.
Unlike a traditional top-speed attempt, the 0–400–0 challenge tests nearly every aspect of a high-performance vehicle. The car must launch effectively, maintain extraordinary acceleration at increasingly high speeds and then slow safely and rapidly from nearly 250 mph. During its record-setting run, the Regera reached 400 km/h in 20.68 seconds before braking to a stop in another 8.13 seconds. The entire exercise covered approximately 1.9 kilometers, or about 1.2 miles.
The record was set at Örebro Airport in Sweden with Koenigsegg development driver Markus Lundh behind the wheel. Although production of the Regera had already ended, the company returned to the model because it believed improved track conditions and newer Michelin Pilot Sport Cup 2 R tires could unlock performance that had not been available during the car’s earlier record attempts.
The Regera Retakes Its Crown
The Regera had previously established a 0–400–0 km/h record of 31.49 seconds in 2019. That achievement remained unbeaten until May 2023, when the all-electric Rimac Nevera completed the same test in 29.93 seconds. Koenigsegg responded just one month later, lowering the mark by more than a second and demonstrating that the aging Regera still possessed remarkable performance potential.
Introduced in 2015, the Regera combined a twin-turbocharged V-8 engine with electric motors and Koenigsegg’s unusual Direct Drive system. Rather than using a conventional multispeed transmission, the system delivered power through a largely fixed-ratio arrangement designed to reduce weight and mechanical losses. The result was a luxury-focused hybrid hypercar capable of producing approximately 1,500 horsepower while delivering relentless acceleration at high speed.
The 2023 result also continued a long tradition of Koenigsegg using production cars as rolling demonstrations of engineering capability. Rather than focusing exclusively on maximum speed, the company has repeatedly pursued acceleration, braking and combined performance records that reveal how effectively an entire vehicle works as a system.
How Fast Is the Record Today?
The Regera’s 28.81-second record did not remain the benchmark for long. On June 26, 2024, the newer Koenigsegg Jesko Absolut completed the 0–400–0 km/h test in 27.83 seconds, lowering the company’s own record by nearly a full second. The Jesko Absolut was developed as Koenigsegg’s lowest-drag model and uses a twin-turbocharged V-8 capable of producing up to 1,600 horsepower when running on E85 fuel.
As of July 2026, the current record for a homologated road car belongs to the Jesko Absolut. On August 7, 2025, Markus Lundh returned to Örebro Airfield and completed the full 0–400–0 km/h run in only 25.21 seconds. The Jesko accelerated to 400 km/h in 16.77 seconds and required another 8.44 seconds to stop, improving the Regera’s celebrated 2023 mark by 3.6 seconds. MORE: What celebrity owns a Koenigsegg?
Although the Regera no longer holds the record, its 2023 achievement remains significant. It reclaimed the title years after the model entered production, briefly defeated one of the world’s quickest electric cars and helped set the stage for the even faster Jesko Absolut. In the rapidly evolving world of hypercars, records rarely last forever, but each one marks another step toward redefining what a road-legal automobile can accomplish.
