Koenigsegg Jesko deep dive: 7 clutches, 1,600 hp, $ 3M

While you develop a substitute automotive for the quickest automotive on the planet, a basic replace shouldn’t be going to chop the mustard. Fortuitously, this was not an issue for Koenigsegg, as a result of none of what the Swedish efficiency model does is what you’ll name typical. That is clearly evident in Koenigsegg's Jesko, which was unveiled Tuesday on the Geneva Worldwide Motor Present in 2019 to switch the Agera hypercars lineup.

Named within the honor of Jesko von Koenigsegg, father of the founder and founding father of Koenigsegg, Christian von Koenigsegg and savior of the corporate in its infancy, the brand new automotive takes up the ideas of the monitor centered on the monitor of the Agera and sees the bar of efficiency climb larger. regardless of substantial enhancements in consolation stage.

A redesigned monohull construction made from carbon fiber round an aluminum honeycomb permits for elevated top and top clearance of the legs in comparison with the Agera, as nicely improved visibility. The dihedral steeple-shaped doorways, which rotate once they lengthen outward, have additionally been redesigned in order to open barely outward and better to assist keep away from scratches attributable to annoying excessive edges and facilitate entry and exit. There are additionally high-end supplies equivalent to leather-based and Alcantara, whereas the 2 seats, geared up with carbon fiber shells, are electrically adjustable, as are the steering column and the pedal field.

The little sticky flywheel has contact controls with haptic suggestions. Behind the wheel is a gaggle of compact digital devices, part of which turns when the steering wheel turns. The central a part of the cluster stays mounted and comprises very important info equivalent to velocity, velocity and enhance strain, however the outdoors, which incorporates gauges indicating the gas stage, the gas strain, the strain of the engine. oil and temperature, strikes with the wheel in order that info isn’t obtained. obscured by the rays. As a contact of freshness, the dashboard of the Jesko can be geared up with an analog pressure meter.

Like all Koenigseggs, the Jesko's roof may be eliminated. This time, nevertheless, the roof has screws for elevated rigidity. Sadly, there isn’t a place to place it within the entrance, as with the Agera. Name it a sacrifice to the gods of aerodynamics.

There will probably be two variations of Jesko. One in all them is the high-support model proven in Geneva, which is meant to develop greater than three,000 kilos of assist and is the perfect possibility for the monitor. And nonetheless within the works is a good quicker mannequin. It should have a smaller splitter and wing, which can scale back the assist but in addition the drag, which can lead to the next most velocity. Additionally, you will have the ability to retailer the roof on the entrance of this mannequin. It bears the code title Jesko 300 and, sure, the quantity refers back to the estimated most velocity of the automotive, higher than 300 mph.

Weight management was one other essential issue within the improvement of Jesko; Koenigsegg boasts that the dry weight of the automotive is barely 2,910 kilos. The aforementioned carbon monocoque, but in addition a lightweight physique of carbon fiber and Kevlar mix, contributed to this aim. Carbon fiber additionally extends to the wheels (aluminum is customary), which measures 20 inches on the entrance and 21 inches on the rear. These are the most important wheels ever mounted on a Koenigsegg, however they’re additionally the lightest: they weigh 13 kilos on the entrance and 16.three kilos on the again. Customary Michelin Pilot Sport Cup 2 tires or Michelin Pilot Sport Cup 2 R tires are wrapped round every of the non-compulsory wheels.

For suspension, Koenigsegg's attribute triplex damper design is described at each ends (the older model of Koenigseggs solely used the design on the rear). Every wheel has its personal damper actuated by a rod and a 3rd damper joins each. This helps to scale back the shocks transmitted between the wheels by the anti-roll bar. The result’s a lowered squat throughout heavy acceleration and elevated trip consolation, which permits for a bigger anti-roll bar. The rest of the suspension contains double triangles, with carbon fiber getting used for the again. And there’s additionally an electronically adjustable driving top that can decrease the automotive virtually to the bottom in monitor mode. The rear steering can also be included within the Jesko and the drive solely applies to the rear wheels.

The engine of the Jesko is a brand new mannequin though it presents the well-known configuration of the corporate, double 5.Zero-liter turbocharger. There are 4 valves per cylinder, two overhead cams, a flat floor crankshaft and dry sump lubrication. Peak gas consumption generates 1,280 horsepower at 7,800 rpm with common gasoline however switches to E85 gas and energy rises to 1,600 hp, 100 greater than a Bugatti Chiron . The utmost torque is 1106 lb-ft, generated at 5,100 rpm.

Koenigsegg said that he had opted for a flat-bottomed crank as a result of its design allowed for higher effectivity whereas reaching the next rpm restrict at 8500 rpm. The sound of the engine must also be way more threatening, which is a attribute characteristic of the flat crankset. Particular consideration has been given to weight discount, particularly for connecting rods and pistons because the engine has a comparatively lengthy stroke and a excessive rotation velocity. The pistons even have a curved face with a particular ceramic coating to assist forestall shocks.

Bigger turbos assist to attain excessive effectivity. Bigger turbos usually result in an elevated delay. To deal with this downside, Koenigsegg has developed an air injection system that gives excessive strain air (290 psi) to drive the compressor wheels at an early stage. The system relies on a small electrical compressor that fills a 20 liter carbon fiber tank with pressurized air.

Every V-Eight cylinder is provided with strain sensors that enable the engine administration system to observe and function every cylinder from one stroke to a different for elevated effectivity. That is essential for emissions rules, as Jesko is anticipated to adjust to requirements as much as 2026, together with California. A 3rd gas injector for every cylinder, a "tumble" valve on the consumption facet to extend turbulence when the air enters the engine (permits to acquire a quicker burn price, which results in higher effectivity) was added, in addition to a heating system for catalytic therapy. Converters at optimum temperatures at an early stage additionally assist improve effectivity.

Koenigsegg refers to Jesko's 9-speed automated transmission, the Mild Velocity ‚Äč‚ÄčTransmission, a compact design that weighs solely 198 kilos, lower than many double-clutch gearboxes with fewer gears. The addition of 9 ahead speeds makes it doable to benefit from Jesko's very large energy and torque ranges. Word that the automotive's engine delivers 737 lb-ft of two,700 rpm as much as 6,170 rpm.

One other benefit of the Koenigsegg transmission over DCTs is that it might probably change instantly between all of the gears, virtually immediately. For instance, if you’re crusing in seventh gear and the fourth is the optimum velocity for a most acceleration of the second, the Jesko will let the drivers downshift immediately. This contrasts with the CSDs that should transfer to an adjoining report.

The 7-clutch design permits the transmission to maintain all of the unused experiences at present prepared for modification. A report choice system known as Final Energy On Demand, or UPOD, makes use of the car and engine velocity to find out the proper ratio for max energy and directs the transmission to have interaction that ratio, no matter the way it pertains to the present report. . The UPOD is activated at any time when the velocity paddles or the shift lever mounted on the middle console are moved to a second notch. By transferring them solely to the primary notch, the gear change desired by the motive force will probably be executed.

Koenigsegg will solely construct 125 Jeskos and, because the automotive is licensed to be offered worldwide, it ought to ultimately attain US sellers. Costs begin at round $ three million.
