Are you in the market for a new hypercar, one with a 5.0L twin-turbo V8 and 1280 horsepower? If so, Swedish manufacturer Koenigsegg has an answer for you with their brand-new Jesko.

Actually, the Jesko makes 1280 horsepower on standard gasoline. Fed a diet of E85 biofuel, its output rises to an even 1600 ponies. The twin-turbo V8 is endowed with a new 180-degree flat-plane crankshaft, new intake, and bigger turbos with air injection when compared to similar engines made by the company in the past. At the heart of this newly designed engine is purported to be the world’s lightest production V8 crankshaft, weighing just 12.5kg.

The tendency of flat-plane engines towards increased vibration is apparently countered by active engine mounts which were first used in the Regera, as well as super-light connecting rods and pistons. The crankshaft is hewn from a solid billet of Swedish steel and its light weight is partially responsible for the engine’s sky-high 8500rpm redline.

Jesko’s new Light Speed Transmission, designed in-house at Koenigsegg and bearing one of the most creative transmission names of our time, is a 9-speed multiclutch unit that does away with traditional synch rings. Most DCT units typically have two clutches: one for even numbered gears and another for odd numbered gears. This allows for fast gear changes but adds weight.

Koenigsegg’s LST comprises several wet, multidisc clutches in a compact package. The LST is capable of quick up and downshifts between gears thanks to the simultaneous opening and closing of clutches, allowing for allegedly seamless acceleration or deceleration. The unit uses vehicle and engine speed to determine the correct gear, directing the transmission to engage that gear no matter its relationship to whatever cog the unit is currently using. If the car is in 7th gear, for example, but 4th is the optimal gear for maximum acceleration at that time, the computer can bypass downshifts to 6th and 5th, shoving the car directly from 7th to 4th. This is significant tech.

Jesko features a monocoque that is 40mm longer and 22mm taller than its predecessor, allowing for generous headroom and legroom, meaning that real humans have a chance of piloting this car. Koenigsegg has also equipped Jesko with an active rear steering system that should increase responsiveness at both high and low speeds. Michelin Pilot Sport Cup 2 tires come as standard, with Cup 2 R tires available as an option.

The aero addenda will not have escaped your notice, said to provide over 1000kg of downforce at speed. That huge double-profile rear wing looks the business, while the front splitter is the deepest ever fitted to a factory Koenigsegg. And, yes, the comany’s awesome dihedral doors are present and accounted for. The Jesko measures about 170mm shorter than an Aventador, if you’re wondering.

The Jesko name was selected in honour of Jesko von Koenigsegg, the father of company founder Christian von Koenigsegg. This is a nice touch and an honour your author cannot bestow upon his own father unless painting his name on a demolition derby car counts, which I highly doubt. No release date for the Koenigsegg Jesko was mentioned As for price, if you have to ask, you probably couldn’t afford it.
