Koenigsegg Jesko - The World's Most Powerful Production Engine


The Koenigsegg Jesko's engine is packed with clever engineering. The 5.0L twin-turbo V8 engine produces 1600 horsepower on E85 fuel, with 1500 Nm of torque! Koenigsegg claims it's the most powerful.
Koenigsegg's latest megacar, the Jesko, will likely be it's last purely internal combustion engine powered vehicle. The car's numbers are unreal. 1600 HP. 1000 kg of downforce. It features Koenigsegg's Light Speed Transmission, a 9-speed, 7-clutch transmission capable of crazy fast shifts from any one gear to any other.
At the heart, is the twin-turbo V8. It's now a flatplane crankshaft, a departure from the Agera's crossplane crankshaft. This means it now revs higher, to 8500 RPM. Features include the ability to run on E85 or gasoline, triple fuel injectors per cylinder, tumble flow intake ports, a compressed air system to eliminate turbo lag, ceramic coated pistons to reduce hot spots, and individual pressure sensors to optimize engine timing. This video will dive into all the details!

    Bonus Fact! The pistons have a ceramic coating on the top to prevent hot spots from accumulating and causing detonation at full power.

Pronunciation is not what this video is about.

    The most powerful engine in the World is the 2021 Bugatti Chiron Supersport rated at 1600hp although I've seen one indicated at 1614hp. And that's on normal regular PUMP gas. E85 is NOT a "pump" gas in the United Kingdom at any petrol station whatsoever. It's also 105 Octane rating and increases fuel consumption +25% upwards. Anyway Bugatti doesn't it and it has far superior torque curves. End of.

    Electrically assisted Turbochargers would be a nice solution here, too - also offering to convert excessive exhaust power (isentrope turbine power - of ALL the mass flow) into electric power instead of wasting them with said valve. Kinda the better VGT for high-power engines... ... hybrid drivetrains need to leave behind their reputation as joyless and unemotional solutions, but start being made into the engine-centered piece of fine art that is possible - the presence of a 48V system offers a lot of cool things that either act as direct advantage or as enabler for engine-intern improvements ... but that would lead too far here and now. Anyway - a great channel, great vidos in general!

    On regular 93 Octane it makes 1280 Hp. On E85 it makes 1600 hp. The SSC Tuatara makes 1350 hp on 91 Octane, 1430 hp on 93 Octane, and 1750 hp on E85. It's also an emissions legal production engine. Chiron SS 300 makes 1578 Hp on 93 Octane and is an emissions legal production car engine. Obviously the Venom F5 makes even more but the car is not complete so we don't know anything about emissions and homologation etc. The original Venom GT was not homologated, did not undergo emissions testing, and was officially registered as a Lotus by the US govt. I'm not sure why koenigsegg is making this claim. Maybe they were just late and didn't notice the competition. Or they probably knew most people don't fact check before talking.

    Hybrids can use regenerative breaking to charge batteries. I wonder if the same concept can be used to pressurize air tanks. 1) A car breaks going into a turn or down a hill 2) Regenerative braking pressurizes a carbon air tank 3) The pressurized air is used to quickly spool the turbo when accelerating Of course I'm leaving out the fun part... exactly how the breaking energy is used to pressure the air tank. Wonder if Engineering Explained knows how.

    Wouldnt the crank position sensor be able to calculate when peak pressure occurs just by position of the pistons? So what then is the point of the pressure sensor? Not a mechanic however I know enough to get by. I'm just curious if you even need that sensor to get the same result. Surely that could be calculated in other ways is all Im saying. Although maybe the pressure sensor would just be more accurate and precise at making peak power regardless of the piston to possibly answer my own question.
