2020 Koenigsegg Jesko

... too much.

1y ago

The Koenigsegg Jesko is a limited production mid-engine sports car produced by Swedish automobile manufacturer Koenigsegg. Introduced at the 2019 Geneva Motor Show, the car succeeds the Agera. The name Jesko is a tribute to the company founder's father, Jesko von Koenigsegg

The engine is a development of the 5.0-litre twin-turbocharged V8 engine used in the Agera. It has four valves per cylinder each with a bore and stroke of 92 mm × 95.25 mm (3.62 by 3.75 inches) and a compression ratio of 8.6:1. The engine has a power output of 955 kW (1,298 PS; 1,281 hp) on normal gasoline and has a power output of 1,195 kW (1,625 PS; 1,603 hp) and 1,500 N⋅m (1,106 lb⋅ft) of torque at 5,100 rpm on E85 biofuel.

Changes from the Agera's engine include the use of a new 180-degree flat-plane crankshaft that saves 5 kg (11 lb) and increases the redline from 8,250 rpm to 8,500 rpm. The Jesko also utilises active rubber mounts from the Regera that reduce engine vibrations in the cabin. The two large turbochargers are equipped with a 20-litre air tank made from carbon fibre, coupled with an electric compressor which feeds pressurised air to the turbochargers at a pressure of 20 bar (290 psi) in order to reduce turbo lag. The engine has pressure sensors for each cylinder in order to achieve real time cylinder monitoring for the multipoint fuel injection system.

The engine is mated to an in-house developed 9-speed multi-clutch transmission called the "Light Speed Transmission (LST)" by the manufacturer.

The new transmission has a weight of 90 kg (198 lb) and it is at least 50% shorter in length than the previous 7-speed dual-clutch unit. It has 21 possible gear combinations (the gears are arranged in two sets of three gears) and seven clutches allowing the driver to jump to any gear without disturbing the ratio. The transmission has a shift time ranging from 20 to 30 milliseconds. It also has an overdrive mode called "Ultimate Power on Demand" that is designed to skip directly to the optimal gear depending on user input, rather than down or upshifting sequentially to that gear.

Chassis and suspension

Unlike its predecessors, the high-downforce variant of the Jesko has Koenigsegg's 'Triplex' dampers at the front and the rear combined with traditional Öhlins dampers. A rear horizontal rear damper prevents the rear from pressing on the ground during hard acceleration. The front dampers stabilise the car at high speeds while an active rear steering ensures further stability at all performance levels.

The carbon tub used in the Jesko is 40 mm (2 in) longer and 22 mm (1 in) wider from that of its predecessor in order for more passenger room. The tub has been redesigned and incorporates an aluminium monocoque structure for increased rigidity

Wheels, brakes and tyres

The car comes standard with forged aluminium center locking wheels, with diameters of 20 inches at the front and 21 inches at the rear. Lighter carbon fibre wheels are available as an option, weighing 5.9 kg (13 lb) at the front and 7.7 kg (17 lb) at the rear. The tyres are Michelin Pilot Sport Cup 2's with codes of 265/35 20 for the front and 345/30 21 for the rear. Michelin Pilot Sport Cup 2 R tyres dedicated for track driving are also available as an option. The braking system uses ventilated carbon-ceramic discs.


The use of a redesigned monocoque improves leg and headroom in the interior of the Jesko when compared to previous Koenigsegg models. Though weight saving is a priority for interior features, the car is still equipped with amenities such as a climate control system, an infotainment system with a 9.0-inch screen, Apple CarPlay and USB phone charging. The car has a unique screens mounted in the steering wheel spokes and a 5.0-inch screen mounted behind the steering wheel displaying vital information to the driver. The seats will be made from hollow carbon fibre but will be electrically adjustable.


The Jesko is equipped with a large carbon fibre front splitter at the front and a boomerang shaped wing at the rear generating 800 kg (1,764 lb) of downforce at 249 km/h (155 mph), 1,000 kg (2,205 lb) at 275 km/h (171 mph) and 1,700 kg (3,748 lb) at its top speed which is yet to be revealed. The low drag variant of the car, which is yet to be introduced, is claimed to have a top speed in excess of 483 km/h (300 mph) in the right conditions by the manufacturer.
