The Koenigsegg Agera RS just became the fastest production car ever

Forget the Bugatti Veyron, the record for the fastest production car has been smashed yet again. Over the weekend, a Koenigsegg Agera RS piloted by test driver Niklas Lilja clocked an average speed of 277.9mph on two runs, making it the fastest production car in the world.

Like the land speed record, the production car speed record requires at least two runs to take place at similar times, with an average speed derived from the two.

The first run, conducted on an 11-mile section of closed road in Las Vegas hit

 284.55mph in one direction, while a second run in the opposite direction managed a top speed of 271.19mph. The latter was also done into a headwind, and also with an uphill gradient, so it’s still pretty impressive.

Koenigsegg managed to get part of Highway 160 closed for up to two days – but the brief nature of the record meant that a few hours was more than enough time. According to, the owner’s son-in-law arranged the road closure, as he works in the film industry.

The new record means the Koenigsegg has now bettered the Bugatti Veyron Super Sport, which has a top speed of 269.86 – as well as the Hennessey Venom GT, which achieved a V-Max of 270.49 mph a few years ago.

But the most insane thing? As the name of the record suggests, the Koenigsegg is now the world’s fastest production car – which means it hasn’t been tweaked or upgraded in any way. Then again, any car with a 5.0-lite twin-turbo V8 engine probably doesn’t need to be tuned at all.
