Koenigsegg has congratulated Bugatti on its recent record of 304mph in a prototype Chiron… while also noting how a ‘high-speed’ version of the Jesko – the company’s rival hypercar – might go even higher than 300mph.

“We want to congratulate them,” a Koenigsegg spokesperson told TopGear.com. “It’s a great achievement. If the homologated production version of the same car can drive faster than 458kph – or 447kph as average speed in two directions – then it will take the crown from the Agera RS as the fastest production car until now.”

Koenigsegg of course, set a record with that customer Agera RS back in 2017. Koenigsegg test driver Niklas Lilja managed a two-way average of 447kph on a closed road in Nevada.

Bugatti has noted how the Chiron could have gone 25kph quicker had it run somewhere like Nevada – higher altitude, less performance but also less drag – opting instead for the confines of its huge Ehra-Lessien oval.

Koenigsegg too, reckons its upcoming Jesko should be capable of going faster than 483kph. Named after company boss Christian von Koenigsegg’s father, the Jesko replaces the Agera RS, and features a 5.0-litre twin-turbo V8 producing 1,578bhp and 1,500nm of torque on E85 biofuel.

“We have said before and say now, a high-speed version of the Jesko should be capable of driving faster than 483kph,” the spokesperson told us.

“The same tools we used to estimate the Agera RS were used to come to this conclusion, and in the Agera RS we underestimated the speed a bit.”

Just when we’ll get to see that top speed run remains unconfirmed for now, but Bugatti’s 489kph blast has got the very highest calibre of speed merchants talking. Not least since the company has now ruled itself out of future top speed runs, Bugatti boss Stephan Winkelmann noting that he intends to work instead on special models.

Lining up alongside Koenigsegg then, is SSC - with the new Tuatara - and Hennessey’s Venom F5, the latter aimed squarely at Angelholm. Indeed, John Hennessey has explicitly called out his rivals in Sweden as being the benchmark. 

“It builds beautiful and fast cars,” he told us. “And when the guys from Angelholm go out to set a speed record they do it the right way.”
