2020 Koenigsegg Jesko

Koenigsegg has unveiled an all-new megacar - the Koenigsegg Jesko - at the 2019 Geneva International Motor Show. Jesko inherits the mantle left by the Agera RS as the leading track-focused, road-legal car for those looking for the ultimate in vehicle performance.

Jesko is named for Jesko von Koenigsegg, the father of company Founder and CEO, Christian von Koenigsegg.

Jesko von Koenigsegg was a key presence at Koenigsegg Automotive during its formative years. His considerable business acumen helped steer the company through many early challenges. Now retired and in his 80's, Jesko von Koenigsegg and his wife, Brita, were on-hand at the 2019 Geneva Motor Show to see his namesake vehicle introduced to the world.

A More Powerful Twin-Turbo V8

Koenigsegg Jesko is powered by a re-designed twin-turbo V8 engine with a new 180-degree flat-plane crankshaft, new intake, bigger turbos with air injection, and more precise pressure control.

At the heart of this newly designed engine is the world's lightest production V8 crankshaft. Weighing just 12.5 kilos, Koenigsegg's new flat-plane 180-degree crankshaft allows Jesko to produce more power with greater efficiency, while achieving a higher 8500rpm rev limit.

The crankshaft is milled by a small manufacturing house in southern Sweden. It is made to Koenigsegg's in-house design from a single solid billet of high tensile Swedish Dievar steel. The flat-plane design allows even firing across engine banks and an even more visceral engine sound. The tendency of flat-plane engines towards greater vibration is countered by active engine mounts first used in the Regera, as well as newly designed, super-light connecting rods and pistons.

Light Speed Transmission (LST)

Koenigsegg Jesko's new Light Speed Transmission - designed in-house at Koenigsegg - is a 9-speed multiclutch unit that does away with traditional synch rings and makes changes between ANY gear possible at near light speed.

Modern DCT's typically have two clutches - one for even numbered gears and another for uneven numbered gears. One clutch/gear is engaged and driving while the control unit pre-selects what it anticipates is the next gear. This solution allows for fast gearchanges but comes with a significant weight penalty and the limitation of only changing to adjacent gears due to anticipation logic constraints.

The Koenigsegg LST allows the driver to change to the optimal gear for acceleration, regardless of that gear's relationship to the current gear. We call this system Ultimate Power on Demand.

For example, if you are in 7th gear and 4th gear is the optimal gear for maximum acceleration, the Koenigsegg LST will allow you to shift directly from 7th to 4th at lightning speed, without waiting for synchronisation. In a traditional DCT, a driver would have to shift through 6th and 5th gears before getting into 4th, a loss of precious time and momentum.
