Who do you think will be the first to break the ‘300mph’ (483 km/h) mark? Hypercar makers have each claimed that their vehicle will be the first to hit the highly coveted top speed for a production car. Will be it Bugatti, with the Chiron? Hennessey Performance with the Venom F5? Or, will it be current production vehicle speed record holder Koenigsegg with their all-new hypercar?

At the 2019 Geneva Motor Show, the Swedish supercar builder revealed the successor to the Agera RS called Jesko. CEO Christian von Koenigsegg also added during its debut that the car is capable of over 300 mph based on their simulations.

Before going into details, let's start with its name. The name Jesko comes from Christian’s father, Jesko von Koenigsegg, who helped him set up the supercar business back when he was still 22 years old. Now that Jesko is 80 years old, Christian named the new model after him as a way of thanking his father.

The Jesko continues to use Koenigsegg’s familiar twin-turbo 5.0-liter V8 setup previously used in the Agera, but has been heavily modified. For starters, the V8 engine now uses a new lightweight, flat-plane crankshaft which is 5kg lighter than the previous unit, an updated intake system, and larger turbos with an ‘anti-lag’ system. The result is 1,280 horsepower on regular gasoline and 1,600 horsepower on E85 fuel.

Hooking up to the engine is Koenigsegg's in-house developed 9-speed, multi-clutch gearbox which the company call’s Light Speed Transmission. Unlike a regular dual-clutch gearbox, the Light Speed Transmission uses seven individual clutches that allows it to shift faster with almost no torque interruption. It allows the car to jump gears between any ratio be it 2nd to 7th or 9th to 4th.

The paddle shifters and console shifter have a dual-stage operation where actuating them into the first position allows the vehicle to shift normally going through each gear. Engage the shifter all the way, however, and the computer automatically jumps into a gear that offers the best acceleration possible.

Externally, the Jesko still carries the familiar Koenigsegg shape and some design cues from the outgoing Agera. The brand’s signature wraparound windshield continues but now has a taller roofline. Up front, there’s a more aggressive bumper with large intakes. The headlights look similar to the one found in the Regera but are smaller and slimmer in design.

The rear appears to be a departure from the Agera’s designs but continues to sport the top-mounted rear wing. Despite that, the carbon fiber monocoque chassis is all-new, giving the Jesko a curb weight of only 1,420kg.

With a new engine, new transmission, and new chassis, will Koenigsegg be the first to break the 483 km/h barrier? We will have to wait and see.
