    Koenigsegg is readying a 483kph ballistic missile to take over the world

    That really isn’t a typo. 483kph. In other words, the magical 300mph barrier. With their new road rocket, Koenigsegg is aiming to go where no other hypercar maker has gone before.

    Sure there have been incredibly fast hypercars before it, cars like the Koenigsegg Regera, McLaren P1, Bugatti Chiron and Hennessey Venom to name a few; but it seems that the Swedish hypercar maker is dead set on passing that threshold long before anyone else.

    And this is what they plan on doing it with – the new Koenigsegg Jesko. The Jesko is a tribute to Christian Von Koenigsegg's father, Jesko Von Koenigsegg, and replaces the Agera as the new ‘megacar” in their line-up. It should be mentioned that the Jesko is primarily built as a high-performance track car, with focus on high aerodynamic downforce and more precise handling. Whereas Koenigsegg's other current production model, the Regera, is designed as a grand touring-oriented offering.

    The engine in the Jesko is a development of the 5.0-litre twin-turbocharged V8 engine used in the Agera. In terms of specifics, it has four valves per cylinder each with a bore and stroke of 92 mm × 95.25 mm and a compression ratio of 8.6:1. While that might not grab your attention, perhaps its outputs will – 955kw on pump fuel or 1,193kw and 1,573nm on E85 biofuel. That’s a whisker under 1,600 horsepower! Comparatively, the Agera “only” produced 1,000kw.

    Changes from the Agera's engine include the use of a new 180-degree flat-plane crankshaft that saves 5kg and pushes the Jesko’s redline from 8,250 rpm to 8,500 rpm. The Jesko also utilizes active rubber mounts from the Regera that reduce engine vibrations in the cabin. The two large turbochargers are equipped with a 20-litre tank made from carbon fibre, coupled with an electric compressor which feeds air to the turbochargers at a pressure of 20 bar 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.

    Much like the Regera, it features a rather special transmission. The transmission is an in-house developed 9-speed multi-clutch transmission called the "Light Speed Gearbox". The new transmission is a full 90kg lighter than the Agera’s 7-speed dual-clutch unit, and weighs just 90kgs, including wet clutches, flywheel, fluids, starter motor and oil pumps.

    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. Impressively, the transmission has a shift time ranging from just 20 to 30 milliseconds. There is also an overdrive mode called "Ultimate Power on Demand" that is designed to skip directly to the optimal gear depending on driver input, rather than down or upshifting sequentially to that gear.

    The Jesko is equipped with a large carbon fibre front splitter at the front and a boomerang shaped wing at the rear that can generate up to 800kgs of downforce at 250kph, 1,000kgs at 275kph and 1,700kgs at its maximum speed. These figures are a 30% increase over the Koenigsegg One:1 at similar speeds, and a 40% increase over the Agera RS. This would put it right up against the McLaren Senna which also generates similar downforce. However, while the Jesko tips the scales at 1,420kgs; the Senna weighs in at just 1,374kgs. But despite those similar numbers, in the power stakes, the Senna trails the Jesko with its ‘paltry’ output of 588kw versus 1,193kw in the Swede.

    In spite of the Jesko being a hardcore track terror, Koenigsegg have made provisions for driver and passenger creature comforts. There are amenities such as a climate control system, an infotainment system with a 9.0-inch screen, Apple CarPlay and USB phone charging. It also has 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 carbon monocoque used in the Jesko is 40mm longer and 22mm wider than the Agera to create more passenger room.

    Unlike its predecessors, the Jesko has 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. It also 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 5.9kgs at the front and 7.7kgs at the rear. As expected, the braking system uses ventilated carbon-ceramic discs.

    The Koenigsegg Jesko inherits the Agera RS's mantle as the ‘ultimate road-legal megacar’ with a laser-like focus on optimal track performance. It ushers in a new era for Koenigsegg, extending the company's legacy of futuristic innovation and scintillating performance. The Jesko is priced from US$2.8 million (ZAR 40 million), with Production of the Jesko limited to 125 units, available in high and low drag variants with 40-50 units being produced each year
