Koenigsegg Jesko Has 1600 HP & 300-MPH?

The Koenigsegg Jesko Has 1600 HP and Promises a 300-MPH Top Speed

It also has a nine-speed gearbox with seven clutches.




According to Christian von Koenigsegg, founder of the supercar company that bears his name, the Jesko is probably the last Koenigsegg without some form of electrification. Yet it should still have enough power and downforce to surpass 300 MPH. And even though it's the successor to the car that's already the fastest in the world, this Agera RS replacement is a clean sheet design. It's built around a longer chassis, hiding a heavily upgraded V-8 that makes 1600 hp when it's running on E85, and a nine-speed gearbox with seven clutches, the like of which we've never seen before.

But perhaps most importantly to Christian, the Jesko is named after his father—who, in a time of great need, poured his life's savings into the Koenigsegg car company.




Now 80 years old and as active as ever, Jesko von Koenigsegg has every reason to be proud of what his son and family have achieved. From humble beginnings 25 years ago, Koenigsegg Automotive is now a juggernaut in the hypercar world. So forget the internal codename "Ragnarok," and say hi to the Koenigsegg Jesko. You'll find that it's more than worthy of the name.





Koenigsegg will build 125 Jeskos in two variants. The track-focused version you see here is designed to produce more than 3000 lbs of downforce with Koenigsegg's revolutionary Triplex suspension at front and rear. The low-drag Jesko version is a more road-friendly machine with a standard front suspension that leaves enough room in the front trunk to stow the removable targa roof.

And good news: No matter which spec you choose, the Jesko will be homologated worldwide—unlike some other extreme performance cars that aren't road legal in certain nations.


Here's everything you need to know about Koenigsegg's ultimate car.

It's a clean brute

We've talked about how special the Koenigsegg V-8 is before. For its last appearance before Koenigsegg goes electrified and camless across the board, the team has really gone the extra mile. You get 1280 horsepower on pump gas, or 1600 hp on E85. That's partly because the Jesko's V8 has a flat-plane crank that weighs just 27.5 lbs, milled from a solid steel billet in southern Sweden. To reduce thevibration you'd get from a flat-plane crank engine while as it approaches 8500rpm, Koenigsegg's engine architect, Dr. Thomas Johansson, came up with new super-light connecting rods that are made from an ultra-strong Swedish steel alloy. Including the bolts, they weigh 19 pounds, which makes them exactly as light as the titanium rods of the Regera engine, but even stronger. Then, there's the pistons.




They weigh 0.63 pounds each, with a ceramic-coated curved face that happens to be the strongest in production. As a result, they can take a crazy amount of pressure while allowing the long-stroke V8 to rev to 8500 rpm.

The Jesko may not use Koenigsegg's camless Freevalve heads, but the ones it has are cast by Formula One suppliers Grainger and Worrall, with an extra "tumble" valve on the intake side to increase turbulence in the air-fuel mix.


Koenigsegg's even-larger turbos would mean even more lag, but the Jesko's engine features a clever system that uses pressurized air to spool up the compressor wheels and heat up the catalytic converters more quickly on cold start. In principle, the system is similar to one used on Volvo's PowerPulse diesel, but Koenigsegg came up with a patent-pending turbo housing design, with pressurized air stored in a carbon fiber tank and blasting into the turbos at up to 290 psi. And with the catalytic converters reaching operating temperature in no time, this twin-turbo Koenigsegg V8 will comply with future global emission standards planned for as far away as 2026.

More air demands more fuel, so the engine now sports three fuel injectors per cylinder. The third injector lives in the intake plenum, squirting in fuel directly above the intake runner for each cylinder. The extra blip of fuel also cools the cylinder, making for a cleaner combustion and less strain on the engine at the top of the power range.

Koenigsegg also threw in individual in-cylinder pressure sensors, a first for road cars. This allows the in-house-designed Engine Management System to monitor and control each cylinder at maximum efficiency. All this results in 1106 pound feet of torque to accompany your 1280 pump-gas horses.

To get the most out of this design, the Light Speed Transmission uses a two-stage control. Both the paddles and the central shift lever have notched mechanisms. A light pull lets you upshift or downshift to the next ratio. Pull further and you'll unleash the "ultimate power on demand" mode, where the system determines the optimum gear for maximum acceleration (or deceleration) and engages that gear immediately.

The Jesko comes with a short-throw "stick-shift" of sorts, in addition to the paddles. Because, why not?

Everything at your fingertips

The Jesko's monocoque is 1.57 inches longer and 0.86 inches taller than the Regera, giving you more headroom and legroom. It's also as rigid as the F1-style pre-preg carbon fiber would suggest, measured at 47,941 lb-ft per degree. That's stiff.

Once inside, what's really new is the steering wheel display and controls. The wheel itself is still made of carbon fiber, now sporting an integrated central screen whose displayed graphics stay level even as the screen rotates with the wheel. Additionally, there are two small configurable touchscreens at your fingertips, which work just like any swipe-capable surface, programmable for future functions as they become available.

With the hydraulics already in place, the Jesko also features the Autoskin upgrade introduced with the Regera, where the car can automatically open and close all its doors and hatches on command. The redesigned dihedral synchro-helix doors now open slightly further outwards and upwards, to make things easier when parked by a high curb. The Autoskin system also includes sensors to protect the automated doors from opening into other objects.

Christian von Koenigsegg's final touch is an analog G-force meter. Located in front of the driver where the instrument panel would normally be, this hand-made piece is a nod to gadget geeks, and, perhaps, fighter-jet pilots.

Teasing the air

The exterior design is the work of Joachim Nordwall, but since Koenigsegg believes this car will be capable of over 300 MPH with its 1600 ethanol-fed horses, most of the Jesko's shapes were necessarily drawn with the help of a wind tunnel.

Helping the car stick is Koenigsegg's deepest front splitter yet (with active flaps behind it), an equally substantial rear diffuser, and the largest top-mounted active boomerang-shaped wing allowed by the law. Even the rear view mirrors help, adding 44 pounds of downforce. In total, the Jesko makes 1763 pounds of downforce at 155 mph, rising to 2200 pounds at 170 mph, and maxing out at 3086 pounds at speeds we can only guess. But as mentioned above, the car is geared to achieve (or exceed) 300 mph, with 30 percent more downforce than the One:1 has.


Double Triplex

Of course, too much downforce could break a car. Not the Jesko, thanks to a monocoque which uses a carbon fiber and aluminum sandwich construction with integrated fuel tanks and rollover bars, and reinforcements made of the strongest fiber in the world, Dyneema.

Bolted to all that is the Triplex Suspension system, which Koenigsegg developed for the Agera in 2010. This setup adds a third, horizontally-oriented damper to the middle of the suspension, keeping the car level without compromising grip. Previous Koenigseggs only featured the Triplex design at the rear, but the high-downforce Jesko adds the Triplex design up front, along with a huge air scoop where the roof storage space used to be.

Koenigsegg also uses the industry’s longest front and rear wishbones, enlarged wheel bearings in lightweight housings, and adjustable dampers manufactured by ÷hlins and further customized with self-developed electronics at the Koenigsegg factory. With their adjustable bump and rebound damping, as well as spring ratio and ride height, these dampers work perfectly with Koenigsegg’s own traction and stability control programs.

The Jesko is also equipped with the Regera's active engine mounts, which give comfort at low speeds and stiffen up for hard driving. Together with the rear-axle steering, this setup promises outstanding handling in a straight line and around corners.

Koenigsegg even spared a thought for trackday enthusiasts: The Jesko's front and rear clamshells are split down the middle, to make it easier to replace crunched body panels. The Jesko uses Michelin Pilot Sport Cup 2 tires as standard, or Pilot Sport Cup 2 Rs if you promise to keep them dry at all times. The latter have a 10 percent larger contact patch and stiffer sidewalls.

The sticky rubber is stretched over larger wheels. Koenigsegg offers both a forged aluminum and a hollow carbon fiber wheel design, 20 by 9.5 inches up front, 21 by 12 out back. Despite being larger than before, the newly-designed carbon wheels weigh just 13 lbs up front, 16.3 at the rear. With these carbon wheels fitted, Koenigsegg was able to bless the Jesko with its largest carbon ceramic brakes ever. From 0 to 250 to 0 again? Again, again and again.

Jesko von Koenigsegg picked up horse racing through his father, who bred and raced horses as a gentleman jockey. Jesko himself spent 20 years as a successful amateur jockey. So it's fitting that the first Koenigsegg Jesko is finished in white with green accents—the colors worn by the jockeys of the Koenigsegg stables.

Not unlike Lord March of Goodwood, Christian von Koenigsegg never caught the horse racing bug. He prefers his horsepower to be gasoline-fueled. But we think the elder Koenigsegg will find much to enjoy in his son's automotive tribute.

Why Koenigsegg Doesn't Use a Dual Clutch Gearbox


The Koenigsegg Jesko's nine-speed seven-clutch gearbox is an absolutely insane bit of engineering. Here's how it works, explained by Christian von Koenigsegg himself.



Koenigsegg's new Light Speed Transmission is perhaps the most impressive component of the 1600-horsepower Koenigsegg Jesko. Designed and built in house, this compact nine-speed is lighter, faster, and more capable than any automatic gearbox on the market. Here's Christian von Koenigsegg's explanation of why they had to come up with it:

If you look back at the Agera, the DCT was always kind of an option for us, but there was nothing existing that could take our up to 1100 pound feet of torque. And if something would have been developed, it would have been like 440 lbs. If you take something like Ferrari and McLaren are using in their V8 cars, their gearbox is for maximum 660 pound feet of torque, and they weigh 275 lbs. Here, we have something capable of 1100 lbs. of torque, with two more gears, which (including the starter motor, all the clutches and the flywheel) weighs 198 lbs. And itís tiny! And you have the advantage of being able to shift from any gear to any gear, lightning fast. Hence the Light Speed name.




Itís also pretty cool, as we donít really have a flywheel on the outside, or a clutch, because they are all inside the casted aluminum housing. So when youíre in neutral, you have super low inertia engine with a super-lightweight crankshaft and connecting rods to the pistons. So, itíll rev like a Formula One engine on idle. And sound completely crazy.




In many ways, itís very simple. We have eight actuators, and eight pressure sensors. One for each hydraulic clutch. There are seven clutches, but thereís an eighth for the electronic differential. We carry that over from the Agera RS. And then thereís one actuator for reverse, and six for the forward gears, on three shafts. So, two clutches per shaft. That makes it possible to mix and match three gears in pairs.

In many ways, it's very simple. And in all the other ways, it's the most bonkers automatic gearbox ever produced. Made in Sweden

There is something positive to be said for human achievement. We live in a rare time in human history where people can have a singular passion to reach unbelievable levels of artistic quality. By the way, his Father looks like a viking.

I can't decide whether I'd like the racing version or the street version. I guess I'll order one of each.

Wow, just wow.

This reminds me of the McLaren F1 when it came out, in that it's the result of the uncompromising, singular vision of one man.

Seriously, that gearbox...

Wonder what Christian could do if you got into Formula 1 racing (ala Adrian Newey or Gordon Murray)?

Like Turbopun said, this is the McLaren F1 of our time.
That gearbox is the stuff of dreams. Hope we see others use that gearbox.
Now...where on earth are they going to do a speed test at that speed!!
Props to Christian K.

It's already sold out!!

Thanks for the article & pics. I saw the Jesko in Geneva this year, amazing in terms of art & design, incredible incredible machine! Would be a dream to go through the factory and speak to Christian about how his vision is realized in these fantastic machines.

Different model, but interesting.

Koenigsegg Only Needs One Carbon Monocoque for All Its Crash Testing

It would be too expensive for the Swedish hypercar builder to crash-test multiple cars. It's cheaper to engineer the most important car to be crashed over and over again.


Swedish hypercar builder Koenigsegg may only produce a handful of cars per year, but it still has to meet the same safety standards as any other automaker. That means a lot of crash testingósomething that could be impossibly expensive for a small company like this, were it not for the strength of its carbon-fiber monocoques.

As founder Christian von Koenigsegg explains in this excellent new video from Apex.One, Koenigsegg only needs to use one monocoque to do all the crash testing necessary for a new model. "We destroy the bodywork on the outside, subframes, crash members and so on, but not the most integral and most expensive part of the car," he said.

"This is very unusual," he continued. "If you take a large car manufacturer, it's much cheaper for them to take a car out of the production line, crash it, throw it away, and take another one. In our case, it's completely different. It's cheaper to rebuild and repair, smashing the same car."

Apex.One got access to remarkable footage of the Koenigsegg Regera going through various crash tests. It's a visceral demonstration of just how strong the car is. Even taking a sledgehammer to the carbon-fiber bodywork doesn't seem to leave so much as a dent.

Koenigsegg isn't like any other carmaker on the planet, building machines that redefine our definition of what's possible in the automotive world. That's what makes it so funny to see it have to deal with the same regulatory hurtles as everyone else. It's a bizarre incongruity, and you really ought to see it for yourself.
