Just when you thought a car from Hennessey or Bugatti would be the first “production” car to top 300MPH, the Swedes remind us that they are in the arena also. In particular, Koenigsegg, the impossibly capable car manufacturer located in Angleholm, Sweden debuts its new Jesko hypercar. And it’s a fast one. According to Koenigsegg, the Jesko has yet to actually go over 300mph but is doing so easily in simulations. Essentially, they would need to find somewhere to do it and someone crazy enough to drive it before a record could be actually be set.
The Jesko Drivetrain
Jesko is Christian Koenigsegg’s father, the man who helped him set up the supercar company when he was just 22-years old. Let’s start with the Jesko engine; its a heavily modified version of the Koenigsegg Agera’s 5.0-litre twin-turbo V8. It now has a flat-plane crankshaft that’s 5kg lighter than the Agera’s, which allows it to rev to 8,500 rpm. Active rubber engine mounts are borrowed from the Koenigsegg Regera which means that any dynamic imbalance vibrations from the flat crank are absorbed and eliminated. Turbo lag is reduced with a 20-liter carbon tank that fires jets of air into the turbos at high pressure to spool them up almost immediately. The result is 1,578HP and 1106lb ft of torque. Problem is, you need a mighty gearbox to cope with that sort of twist so Koenigsegg built its own from scratch. Dubbed the Light Speed Gearbox (LSG), it’s a 9-speed multi-clutch transmission with six clutches that one can select at any time. The result, says Warren Henry Auto (Miami, FL), is that you can jump from one gear to ANY other without going through the ratios between.
Pull the two-stage paddle shifting paddle all the way and the Jesko jumps to the gear that offers the best acceleration at that time. Koenigsegg’s evocative name for the system is UPOD – Ultimate Power on Demand. The Jesko also gets a Triplex damper at the front to complement the more traditional Ohlins dampers. The rear-wheel steering has also been added and it wears Koenisegg’s lightest ever carbon fiber wheels – 21-inch at the rear, 20-inch and at the front – fitted with Michelin Pilot Sport Cup 2s tires as standard. Each wheel is hand-made and takes 40 hours to finish…, the retail price for a set is $65,000.
And a Jesko driver won’t be wanting for luxury. For maximum showoff mode, the front hood, doors and rear clamshell hatch can all be opened at the touch of a button, there’s climate control, an infotainment system with Apple CarPlay, USB sockets and wireless charging for your phone. New for the Jesko is a screen attached to the wheel that displays all relevant information.
Only 125 Jeskos will be built, at a rate of around 40 to 50 a year, so compared to the 25 Agera RS and 80 Regeras sold, that’s progress. But with prices starting at just under $3m plus local taxes, it’s up there. However, a vast number of future production is already spoken for.
