Have a supercar in your garage that you want to run to its limit? Head to VMax200. The event is held several times a year on airfields across the UK, and allows drivers to push their high-performance machinery to the limit.

A Koenigsegg, it should come as little surprise, just set the record at the latest one. And not for the first time, either. The car in question is badged as the Agera RSN. That last letter, we gather, was probably tacked on by its commissioning owner, Neil Miller. But at its root, it’s an Agera RS – the last one that will ever be made, in fact.

Neil took the wheel, with his son riding shotgun, at the Kendew Barracks near Leicester. And he managed to hit a top speed of 234 miles per hour – or about 377 km/h on the metric scale. Not bad for an amateur, and a testament to the car’s abilities. But Koenigsegg’s factory driver managed more.

Koenigsegg Beats Koenigsegg

After tinkering with the setup (and taping off some of the seams), Niklas Lilja coaxed the hypercar up to 242 mph (389 km/h). “The car was strong all day,” said Lilja. “We had to do a little fine tuning on the active rear wing as we progressed through the day so we probably left a few mph on the table for next time.”

That was enough to set a new record for the recurring event by a single digit. The previous record was also set by a Koenigsegg. The One:1 managed 240 mph (386 km/h) two years ago with LMP1 racer Oliver Webb behind the wheel. That car, if you can believe it, was electronically limited to that speed. The bottom line is that we won’t be surprised if a Koenigsegg – this or another – breaks that record again.
