The new Jesko, shown at the NY International Auto Show from April 19 to 28, 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 – the all-new Megacar from Koenigsegg – is powered by a newly designed, 1,280 to 1,600 horsepower (depending upon fuel used), twin-turbocharged V8 engine that benefits from significant changes to the Agera engine it replaces. At the core of the engine is the world’s lightest V8 crankshaft. Weighing just 27 pounds, Koenigsegg’s new flat-plane 180-degree crankshaft allows Jesko to produce more power, with greater efficiency, while achieving a higher 8,500rpm rev limit.
The crankshaft is milled at small manufacturing house located in southern Sweden. It is made to Koenigsegg’s in-house design from a single solid steel billet. Its flat-plane design allows even firing across engine banks and an even more visceral engine sound. Koenigsegg has countered the tendency that flat-plane engines have towards greater vibration by designing new super-light connecting rods and pistons. Koenigsegg’s engine architect, Dr. Thomas Johansson, designed the connecting rods. The connecting rods and bolts are made from premium Swedish steel, light as previous generation rods made from titanium, but even stronger.
The piston’s curved face shapes the combustion chamber in such a way so as to reduce peak pressure while maintaining high average pressure. The ceramic coating on the face of the lightweight pistons prevent hot spots and detonation when the engine runs at maximum power. Minimal reciprocating weight is important because Koenigsegg engines have a very long stroke and at 8,500rpm, efficiency of movement becomes critical.
The Koenigsegg Jesko features an all-new nine-speed, multi-clutch LST transmission – the second transmission to be 100% designed and built in-house, following the Direct Drive system designed for the Regera. The Koenigsegg Light Speed Transmission (LST) represents a scale of evolution not seen since the development of modern dual-clutch technology at the turn of the century.
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 80s, 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.
