Koenigsegg and Bugatti are always trying to outdo each other. Bugatti set the hypercar benchmark with the reveal of the Chiron last year, a mad successor to the Veyron with 1,500 hp. Koenigsegg's response was the insane Regera, which also packs 1,500 hp to match the Chiron's outrageous output. Bugatti dominated the headlines last month after the Chiron broke an astonishing speed record, reaching 0-249-0 mph (0-400-0 kph) in just 41.96 seconds. However, it was only a matter of time before Bugatti's Swedish supercar rival fought back.

It looks like Koenigsegg may have set a new hypercar speed record, as a Bugatti-baiting photo has been posted on the automaker's social media channels showing what looks like an Agera RS speeding down a runway with the tagline "0-400-OMG," strongly implying that Bugatti's record has been beaten. Koenigsegg promises that more information about the record will be "coming soon." The Agera RS improves on the Agera R and S models by utilizing technology derived from the incredible One:1, which has a power to weight ratio of 1bhp per kg. It's powered by a twin-turbo 5.0 liter V8 that produces 1,160 horsepower.

Its kerb weight is just 1395 kg, and aerodynamic elements such as an active spoiler and dynamic underbody flaps help increase downforce to maximise its track performance to attempt an attack on the Bugatti Chiron's record run. Has the Koenigsegg Agera RS beaten the Chiron's 0-249-0 mph record? It sounds like we won't have long to find out, so watch this space. Don't expect this rivalry to end any time soon either, as Bugatti will be removing the limiter to chase a new outright speed record for a production car in the Chiron next year.
