Koenigsegg Jesko, the extreme hypercar with the fastest engine in the world
Koenigsegg Jesko
Last summer, production began - within the industrial plant located in Sweden, in Ängelholm - of Koenigsegg Jesko, the extreme hypercar heir to the Agera RS. It is, without a shadow of a doubt, a vehicle designed and developed to grab the title of fastest production car in the world. Well, in this regard, the founder of the house Christian von Koenigsegg himself seems to be convinced and, through a video, illustrated the incredible characteristics of the hypercar, underlining the acceleration peaks that Jesko is able to reach.In the course of some tests that have been carried out, it seems to have emerged that the 5-liter V8, starting from the minimum, reached 7,800 rpm, limited in neutral, but in running condition the 8,500 rpm Therefore, Christian von Koenigsegg, said that, with such high numbers, it is possible to guarantee greater control of the vehicle but also a more immediate reaction to the commands. In short, we could be facing the hypercar with the most responsive engine in the world. Koenigsegg Jesko is equipped with a transmission developed by LST (Light Speed Transmission). Designed to become the fastest and most responsive gearbox ever made, seven oil bath multi-plate clutches are used - positioned within a compact and lightweight structure - thanks to which it is possible to accelerate and decelerate avoiding interruptions. In this way it will be possible to exploit the engine torque as much as possible.
The extraordinary vehicle is equipped with a 5-liter V8 capable of delivering a power of 1,600 hp and 1,500 Nm of torque with E85 fuel. However, the power is reduced if a normal 95 octane petrol is used, reaching “only” 1,280 hp. Recall that only 125 copies of the very powerful Koenigsegg Jesko will be made, the price of which should be around 2.5 million euros. The first hypercars of the Swedish brand will be delivered during the spring of next year.
Cold-starting a Bugatti Chiron and revving a Koenigsegg Jesko

Those quad exhaust tips aren’t on the regular Bugatti Chiron, and they sound phenomenal early in the morning.
The Bugatti Chiron Super Sport 300+ is a rare and awesome car, first revealed in 2019 and one of the few cars to top 300mph (482kmh).
In fact, it was the first, with a prototype without a speed limiter clocking a verified 490kmh on August 2, 2019, prompting a number of cars following up with claims to beat the Chiron’s top speed.
That prototype used a modified 8.0-litre W16 engine, producing 1177kW with no changes to the transmission or all-wheel drive system, as well as numerous weight-saving measures. Bugatti carried the engine over into the limited production run, which included a new exhaust.
Turns out, an exhaust tuned for producing as much power as possible with little regard to emissions sounds pretty damn good.

A video from October 2020 shows a Chiron Super Sport 300+ starting up on at a rainy Bonhams event (going by the flags around the car) and it sounds like an old World War II fighter plane. Or in short – absolutely brilliant.

If you want to go very fast in a straight line, and have a bank account with about eight digits (not including overdraft), it’s hard to beat the Chiron Super Sport.
It’s a different sort of awesome to Koenigsegg’s recent engine video, which shows the 5.1-litre twin-turbocharged V8 revving from idle to the 7500rpm limit in less than a second.
That’s not far off how quickly a superbike engine can rev, which are about a fifth the size with much smaller and lighter internals.
Koenigsegg says its new V8 has a crankshaft weighing just 12.5 kilos, while the pistons themselves weigh just 290 grams each.
The conrods are made from “premium Swedish steel” and weigh 540g each, including bolts, which is apparently as light as previous generations’ titanium units while being stronger. How that’s possible is beyond me.
Even more interesting is that the design of the engine incorporates a long stroke, which typically doesn’t lend itself well to fast, high-revving applications.
