Jesko – the all-new megacar from Koenigsegg – is powered by a newly designed, 1280hp (1600hp on E85 in some markets), twin-turbocharged V8 engine that benefits from significant changes to the Agera engine it replaces.
At the core of the newly designed engine is the world’s lightest 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 located in southern Sweden. It is made to Koenigsegg’s in-house design from a single solid steel billet.
The 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.
The connecting rods were designed by Koenigsegg’s engine architect, Dr. Thomas Johansson. The connecting rods are made from premium Swedish steel. At just 540g – including bolts – they’re as light as previous generations 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 piston prevents hot spots and detonation when the engine runs at maximum power. The piston weighs just 290 grams. Minimal weight is important because Koenigsegg engines have a very long stroke and at 8500rpm, efficiency of movement becomes critical.
