It packs quite possibly the most powerful internal combustion engine of any homologated production car in history.
Koenigsegg has revealed its at the Geneva Motor Show, and it certainly lives up to the standard set by its . Meet the all-new Koenigsegg Jesko named after Jesko von Koenigsegg, the father of company Founder and CEO, Christian von Koenigsegg.
The Jesko is powered by a re-designed twin-turbo V8 engine, which produces 1,280 hp on regular gasoline and 1,600 hp on E85 fuel in certain markets. That makes it the most powerful Koenigsegg internal combustion engine ever made, and quite possibly the most powerful internal combustion engine of any homologated production car in history. Peak torque sits at 1,106 lb-ft at 5100 rpm.
The V8 unit features a new 180-degree flat-plane crankshaft, new intake, bigger turbos with air injection, and more precise pressure control. It also features the world’s lightest production V8 crankshaft weighing just 27.5 pounds, allowing the Jesko to produce more power with greater efficiency while achieving a higher 8500 rpm rev limit.
In an industry first, Koenigsegg says the engine has been re-designed to house a tumble valve on intake and individual pressure sensors for each cylinder in order to achieve real-time, precision monitoring of every cylinder.
The Jesko’s momentous power is sent through a nine-speed multi-clutch transmission designed in-house. Koenigsegg calls it the "Light Speed Transmission," which does away with traditional synch rings and allows the driver to change to the optimal gear for acceleration, regardless of that gear’s relationship to the current gear. For example, the Light Speed Transmission will allow you to shift directly from 7th to 4th at lightning speed, without waiting for synchronization. It also only weighs 198 pounds and has a compact design, allowing more room for the advanced underfloor aerodynamics.
Like other Koenigseggs, the Jesko is built on a monocoque chassis that is 1.5 inches longer and 0.8 inches taller than its predecessor, allowing for more generous headroom and legroom. Elongated wishbones combine with the largest wheel bearings used in a road car to provide "the ultimate in responsiveness and feel.” The Jesko also features an additional active damper on the front suspension and a new active rear-wheel steering system to improve responsiveness. An aggressive aerodynamics package also features a massive rear wing to help the Jesko provide over 2,200 pounds of downforce at 170 mph – that’s a 30 percent increase over the Koenigsegg One:1 at similar speeds, and a 40 percent increase over the Agera RS.
Elsewhere, the front splitter is the deepest ever designed for a Koenigsegg and features enlarged, active under-body flaps to either maximize or release downforce. Even the rear wing mirrors provide 44 pounds of downforce while directing airflow to the rear of the vehicle. The Jesko rides on new optional carbon fiber wheels that are the lightest and strongest production wheels of their size, measuring 20” x 9.5” at the front and 21” x 12” at the rear. Michelin Pilot Sport Cup 2 tires come as standard - these were the same tires worn by the .
As with other Koenigseggs in the past, the Jesko’s lightweight carbon roof can be removed, transforming the car a coupe to a roadster in minutes. Interior luxuries include a TFT touchscreen, USB inputs, inductive phone charging, Bluetooth connectivity, automated climate control, leather or alcantara trim with contrast stitching, a digital warning system, electrically adjustable mirrors, adjustable pedals and steering, and parking sensors. The infotainment system includes a five-inch, digital dashboard mounted on the steering wheel and a nine-inch central display. The Jesko steering wheel also has two small touchscreens with haptic controls for easy access to functions including phone, audio, and the vehicle lift system.
