The
Koenigsegg Jesko is a limited production mid-engine
sports carproduced by the Swedish automobile manufacturer
Koenigsegg. The car was introduced at the
2019 Geneva Motor Show and was completely sold out before the show ended. Succeeding the
Agera, the Jesko is named as a tribute to the company founder's father, Jesko von Koenigsegg. There are two variations of the car, the "Absolut" and the "Attack
The engine is a development of the 5.1 L (5,065 cc)
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 1,280 hp (1,298 PS; 954 kW) at 7,800 rpm and 1,000 N⋅m (738 lb⋅ft) of torque at 2,700 to 6,170 rpm on normal petrol and has a power output of 1,600 hp (1,622 PS; 1,193 kW) 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.
