Koenigsegg has a thing for the Geneva Motor Show, introducing its first customer car there, the CC82, in 2002. Since then, the Swedish carmaker has trucked wares like the CCX and CCXR, Agera, Regera, and Jesko from Angelholm to greet the world in the Romandy region of Switzerland. According to a report in The Supercar Blog, the ritual takes place again this year, with Koenigsegg supposedly debuting a concept called Mission 500. The concept, so the story goes, will preview the vehicle the hypercar maker plans to use to crack the 300-mile-per-hour barrier. The “500” in the name refers to 500 kilometers per hour, which equates to 310.6 miles per hour. There are rumors of two more cars on display, but the Mission 500 concept is the centerpiece.

Getting any production car to reach 300 miles per hour is a stellar feat, one accomplished last September by the Bugatti Chiron Super Sport 300+. The task is so difficult that every extra mile per hour beyond 300 could be considered its own Herculean conquest of several categories of physics. The Molsheim coupe ran 304.77 mph (490.48 kilometers per hour) at Volkswagen’s Ehra-Lessien track. If Koenigsegg can hit the magic 500, that additional 6 mph represents a gargantuan achievement.

It’s not clear if the Mission 500 concept is a new vehicle or based on the Jesko. Company boss Christian von Koenigsegg has said he has a 300-mph variant of the Jesko in mind that only needs some extreme aero to manage the task. The CEO has practical math to work with for his claim, his company having got the Agera RS up to 277.87 mph in 2017 — that speed averaged after runs in both directions, unlike the Chiron Super Sport run that was timed in one direction only. If the Mission 500 is Jesko-based, we’d expect to see the 5.0-liter V8 amidships that makes 1,577 horsepower and 1,106 pound-feet of torque on E85, or “just” 1,262 hp and 941 kW on 95-octane pump gas.

Top Fuel NHRA racer Brittany Force set a national record last year at 338.17 mph through the speed trap, using a 500-cubic inch (8.19-liter) supercharged V8 with 10,000 horsepower to do it. The idea that we could see a passenger car with navigation and two cupholders get within 30 mph of that speed is outstanding. Even better is the idea that, assuming the Swedes pull it off, Hennessey or SSC might attempt to beat it. Come on, Geneva.
