It’s no secret anymore that Bugatti has broken the speed record with a top speed of 304.77, but John Hennessey has already made a jab at the fact it was with a modified car, and in only one direction. You can read about that here.

Today, Koenigsegg has also had the time to ford their own response, and it’s about as back handed as Hennessey’s.

A spokesperson told TopGear.com the following:

“It’s a great achievement. If the homologated production version of the same car can drive faster than 284.55mph – or 277.9mph as average speed in two directions – then it will take the crown from the Agera RS as the fastest production car until now.”

I think their point was very obvious. Bugatti has not broken any records until they test the car in the exact same way as every other car that has gone before it. This means a two-way measurement, with an average speed extracted from it.

Koenigsegg also hint at the performance of their upcoming Jesko. Named after CEO Christian von Koenigsegg’s father, the Jesko uses a 5.0-litre twin-turbo V8 to produce 1,578bhp and 1,106lb ft og torque using E85 fuel. This, according to the Swedish company, should exceed the performance of the Chiron.

“We have said before and say now, a high-speed version of the Jesko should be capable of driving faster than 300mph,” 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.”

Still to comments on the Chiron’s record is SSC, with their highly strung Tuatara. We”re reaching out to them to see if they have any comments on the viability of Bugatti’s run.
