The Koenigsegg Jesko Absolut Might Have An Unbeatable Top Speed
In theory, the Jesko Absolut can do 330 mph without specially made tiresby Robert Moore, on LISTEN 05:01
When the Geneva Auto Show was canceled, just about every other automaker stopped what they were doing and started tearing down their stands. Then there was Koenigsegg that continued to build its entire show-worthy outfit. Nobody really understood why until Christian von Koenigsegg kicked off a live presentation from that very booth. That’s when we learned about the awesome engineering feat that came courtesy of the new 2021 Gemera Hyper GT but before that happened we learned a lot about the new Jesko Absolut – a model that aims to be the fastest car Koenigsegg will ever build and one that, apparently, might be able to break not only the Bugatti Chiron Super Sport 300+’s record but the mythical road-car speed of 330 mph.
How Fast is the Koenigsegg Jesko Absolut?
For now, not even Koenigsegg knows how fast the Jesko can actually go. During its debut via a live-stream from Geneva, Christian von Koenigsegg was adamant that the Jesko Absolut would absolutely shatter the top speed record as we know it. The car will also be the fastest Koenigsegg ever made, but that’s a story for another today.
Today, we’re here to talk about how fast the Jesko Absolut might actually go. If it’s the fastest Koenigsegg ever, then we know it can go beyond the Agera RS’ top speed of 277.87 mph, but how fast is still a mystery. In an interview with Road and Track, Christian von Koenigsegg filled us in on some new information and even claimed that the car could, in theory, hit 330 mph (532 kph.) This was determined by taking a number of factors into account, the most important of which is the Absolut’s drag coefficient of just 0.278. That, factored in with Koenigsegg’s outrageous 5.0-liter V-8 and silky-smooth nine-speed automatic, make this crazy type of top speed possible. At the same time, CvK also remains confident that the Jesko Absolut can function as a daily driver as well.
"If you run the numbers, you take the frontal area, the cd, the power, the gear ratio, the power curve... the simulations say 532 km/h (330 mph), or something like that," Koenigsegg said. "It's, of course, a theoretical number, but that's what simulation tells us. We don't really have ambition to drive that fast. The end result will be location, driver willingness, and car's capability. But theoretically, it looks extremely fast."
During the live stream debut, CvK was clear to point out that there’s a lot of work to do before they can attempt a top-speed run. The only options for this kind of event are either a specially made test track – like the Johnny Bohmer Proving Grounds or VAG’s Ehra-Lessien Proving Grounds. The only problem is that the Former isn’t long enough, and it’s not likely VAG (which own’s Bugatti) would stand back and let a competitor beat the Chiron’s record. In the end, Koenigsegg will need to find a road or track that is at least 5.5 miles long, and the conditions need to be right.
”The problem is when you start reaching your top speed, and you want to get your last 5-10 mph, they come very, very slowly while the car is flying forward and just consuming miles so quickly.”
Perhaps there’s a nice, long chunk of road somewhere in the world where the Jesko Absolut can show us just what it’s got. At JBPG, for example, it’s estimated that the Absolut would only do about 85-percent of its top speed. And, even if the Jesko doesn’t topple 330 mph – it all boils down to the conditions, the feel of the car, and the balls on the driver, among other things – there’s a damn good chance that it could set a record that’s unbeatable for a long time to come.
Does the Jesko Absolut Need Special Tires to Hit Its Top Speed?
Tires are another big issue when it comes to these crazy top speed runs, and one would assume that for the Jesko Absolut to hit 330 mph (or anything close to it,) a special tire would have to be made. After all, blowing a tire at 100 mph can be deadly, so just imagine how catastrophic it would be to suddenly lose rubber at 320 mph+. Surprisingly, tires don’t seem to be much of a concern. The same tires used on the Agera RS were tested at 330 mph with an issue – something that surprised not only Koenigsegg but Michelin as well.
”Michelin, when they were there during our testing, they didn't believe their eyes. How kind our cars are to their tires.”
Of course, there will be plenty of verification made before that top speed run is tested in the real world, just for the safety of the driver, but if everything goes according to plan, the record attempt will be made within the year.
