When you build automobiles that retail for the sum of a few million dollars a pop, you can bet that some pretty neat technology is involved. In this regard, Koenigsegg, a world-famous Swedish supercar company, certainly doesn’t disappoint.  In this article for exotic technology geeks, we will look at some of the wild stuff you will find in new Koenigsegg Jesko supercars.

Flat-plane crankshaft

The engine destined for the Jesko is based on the famous Koenigsegg Regera V-8. This engine kicks out 1280 horsepower on pump gas or 1,600 hp on E85 gas. That’s partly because the Jesko’s V8 has a flat-plane crank that weighs just 27.5 lbs and milled from a solid steel billet. To reduce the vibration you’d get from a flat-plane crank engine while as it approaches redline, Koenigsegg’s engine architect, Dr. Thomas Johansson, designed super-light connecting rods made from an ultra-strong steel alloy. 

Turbos with pre-spool

Koenigsegg’s larger turbos would mean even more lag, but the Jesko’s engine uses pressurized air to spool up the compressor and heat up the catalytic converters more quickly on cold start. In principle, the folks at Warren Henry Auto Group say the system is similar to Volvos’ PowerPulse technology but Koenigsegg came up with a new design with pressurized air stored in a carbon fiber tank and blasting into the turbos at up to 290 psi. 

Three injectors per cylinder

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

In-cylinder pressure sensors

Koenigsegg also threw in individual in-cylinder pressure sensors, a first for street cars. This allows the in-house-designed Engine Management System to monitor and control each cylinder at maximum efficiency which results in 1,106 pound-feet of torque to accompany the 1280 pump-gas horses.

Light Speed Gearbox

The gearbox is unlike anything you’ve ever seen. The Light Speed Gearbox (LST) has nine forward gears and seven wet multi-disc clutches. Yet at just 198 lbs, it weighs significantly less than your average dual-clutch transmission. It’s also half as long as Koenigsegg’s previous seven-speed transmission and thanks to the simultaneous engaging and disengaging of those clutches, it offers “near light-speed” gear changes. 

Active engine mounts

The Jesko is also equipped with the Regera’s active engine mounts, which give comfort during ordinary driving yet stiffen up for hard driving. Together with the rear-axle steering, these active mounts promise outstanding handling.

Wheels

Koenigsegg offers both a forged aluminum and a hollow carbon fiber wheel designs, 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. 

Triplex suspension

The Jesko offers Koenigsegg’s Triplex Suspension system, which was 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 upfront.

Interior

Once inside, what’s really new is the steering wheel display and controls. The wheel itself is still made of carbon fiber, and sports 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.
