fastest car in the world 2023
The Koenigsegg Jesko is a limited production mid-engine sports car, introduced at the 2019 Geneva Motor Show. Named after the founder’s father, Jesko von Koenigsegg, the car is sold out before the show ended. It comes in two variations: “Absolut” for top speed and “Attack” for track-focused performance.
Fastest car in the world 2023
The automotive world has been aiming for the 300-mph mark, with some cars moving well past that threshold. The Koenigsegg Jesko Absolut, a top-performing car, recorded a 330 mph top speed in 2023. Its twin-turbocharged 5.0-liter V8 engine produces 1,600 horsepower and 1,106 pound-feet of torque. However, the car also boasts a super-slippery 0.278 drag coefficient and a nine-speed transmission called a Light Speed Transmission (LST), which shifts at almost light speed.
The gearbox is impressive, featuring several wet multi-disc clutches and a lightweight construction. The Jesko Absolut is not the only car or automaker to achieve this impressive speed. Not only does it have a powerful engine, but its engineers have also given it a unique design.
The Jesko engine is a development of the 5.0-litre twin-turbocharged V8 engine used in the Agera. It has four valves per cylinder and a compression ratio of 8.6:1. The engine has a power output of 955 kW at 7,800 rpm and 1,000 N⋅m of torque at 2,700 to 6,170 rpm on normal gasoline and 1,195 kW and 1,500 N⋅m of torque at 5,100 rpm on E85 biofuel. The engine features a 180-degree flat-plane crankshaft, active rubber mounts from the Regera, and two large turbochargers with a 20-litre carbon fibre air tank and an electric compressor. The engine also has pressure sensors for each cylinder for real-time cylinder monitoring for the multipoint fuel injection system.
The engine is connected to a 9-speed multi-clutch transmission called the “Light Speed Transmission (LST),” which is at least 50% shorter in length than the previous 7-speed dual-clutch unit. The LST has 9 forward gear combinations, with an input shaft with 3 fixed gears, a secondary shaft with 3 gears fixed to the output shaft, and 3 clutched gears mated to the input shaft and an output shaft with 4 clutched gears. This allows the transmission to change gears without interruption in power delivery.
The engine’s crankshaft is mated directly to the LST, using the rotating mass of the transmission components instead of a traditional flywheel. The transmission has a shift time of 20 to 30 milliseconds and an overdrive mode called “Ultimate Power on Demand.” The transmission is controlled by an onboard computer, using engine and road speed data to engage a gear. Gears are selected by the driver using shift paddles or the gear selector.
Wheels, brakes and tires
The car comes with forged aluminium centre lock wheels, with options for lighter carbon fibre wheels. The tyres are Michelin Pilot Sport Cup 2’s, with codes 265/35 20 for front and 345/30 21 for rear. Track-driving Michelin Pilot Sport Cup 2 R tyres are also available. The braking system uses ventilated carbon-ceramic discs. The car weighs 5.9 kg at the front and 7.7 kg at the rear.
Chassis and suspension
The high-downforce Attack variant of the Jesko features Koenigsegg’s ‘Triplex’ dampers at the front and rear, combined with traditional Öhlins dampers. It also features a horizontal rear damper to prevent the rear from pressing on the ground during hard acceleration. The carbon body tub is 40mm longer and 22mm wider than its predecessor, providing more passenger room and an aluminium monocoque structure for increased rigidity.
The Jesko, a Koenigsegg model, has been redesigned with a monocoque for improved leg and headroom. It also features a climate control system, an infotainment system with a 9.0-inch screen, Apple CarPlay, and USB phone charging. The car also has unique screens mounted in the steering wheel spokes and a 5.0-inch screen behind the steering wheel. The seats are made of hollow carbon fibre and electrically adjustable.
The Jesko, a car with ‘Autoskin’ capabilities, shares Koenigsegg’s Regera’s capabilities, allowing remote door and hood operation. It also allows hydraulically lifting of front and rear axles for additional ground clearance. The doors have been redesigned for wider openness and increased ground clearance, and the roof features screws for high-speed driving stability.
The Jesko, a compact car, will be limited to 125 units annually, with 40-50 units produced each year. It will be homologated worldwide, unlike its predecessors. The Jesko will be offered in high-downforce Attack or low-drag Absolut configurations, with slight differences between the two. The Attack variant features a dual front and rear ‘Triplex’ damper system and aerodynamic features for track use. The first pre-series production Jesko was revealed in July 2021, with delivery slated for spring 2022. The first car was delivered in June 2023. All build slots for the Jesko were sold out in March 2019.
