New Koenigsegg Jesko chases record-breaking 300mph top speed
If Koenigsegg’s own simulations are correct, the Jesko is theoretically capable of over 300mph – given a long enough run and a tyre strong enough to handle the intense forces of travelling at that speed.
If true, Koenigsegg would be taking the record from itself – its Agera RS holds the crown currently, with a top speed of 277mph.
How does it achieve that level of performance? It’s all down to the world’s lightest production V8 engine – a remarkable twin-turbocharged 5.0-litre unit – that weighs just 189kg. It produces 1,262bhp as standard but that’s on conventional petrol – when run on high-performance E85 ethanol, the Jesko produces an incredible 1,578bhp.
That power is fed through a nine-speed transmission with six clutches – again, very light at just 90kg – which sends power to the rear wheels. Koenigsegg’s computerised the system for greater driveability, and claims that the Jesko can pre-empt the driver’s intentions, lining up the correct gear based on road speed and engine revolutions.
The whole setup sits within a brand-new carbon fibre tub chassis, and suspension highlights include a rear damper to prevent the car ‘squatting’ under hard acceleration as well as active rear-wheel steering.
Aerodynamics are the name of the game on the car’s exterior, keeping the Jesko stable at high speeds. The enormous front splitter and vast, centre-mounted rear wing generate 1,400kg of downforce at the Jesko’s still-undisclosed top speed.
Despite its singular focus on speed, the Jesko is quite luxurious inside – driver and passenger enjoy climate control and an infotainment system with Apple CarPlay and Android Auto.
The price? More than £2m, and speed-freak oligarchs will have to be quick, as Koenigsegg’s only making 125 units.
