Whilst a number of supercars publish theoretical top speeds, Swedish manufacturer Koenigsegg demonstrated its Agera RS can reach a top speed of 447kmh – making it the proven fastest car in the world.
On November 4, 2017, the Nevada Department of Transportation closed an 11-mile stretch of road just outside Las Vegas. Koenigsegg turned up with a customer-owned Agera RS and Koenigsegg factory driver Niklas Lilja put down two high-speed runs (in opposing directions). The average pace (including one run at 459 kmh) was recorded by the Guinness Book of World Records.
Koenigsegg develops and produces most of the main systems, subsystems and components needed for their cars in-house instead of relying on subcontractors. It also develops programs of plug-in electric cars’ systems and next-generation reciprocating engine technologies.
In January 2019, Koenigsegg sold a 20 percent minority stake in the company to a Chinese funded company, National Electric Vehicle Sweden (NEVS), for $171 million. They also announced the formation of a new joint venture to make cars using technologies from both companies.
