This Is How The Koenigsegg Gemera's Inline-Three Develops 600bhp
The Koenigsegg Gemera is awash with mind-blowing details. The most fascinating element is surely the engine - despite having only three cylinders and displacing just 2.0 litres, it produces 600bhp.
It’s also mounted in the middle yet powers the front wheels and has a seven-clutch gearbox, but less focus on one thing at a time - in this case, the output. How, exactly, has Christian and his team pushed so much out of such a small and light (70kg) package? Thankfully, YouTube’s most prominent whiteboard enthusiast Engineering Explained is here to make sense of what’s going on inside the Tiny Friendly Giant’s diminutive frame.
We’d recommend watching the whole thing and absorbing all of the knowledge Jason Fenske lays down, but what we will say is there are a few main areas that help the TFG achieve a specific output two and a half times greater than the next highest three-pot.
The TFG has huge bores and a very long stroke, but despite that, it’s capable of revving to 8500rpm. In other words, you have big pistons moving very far and very quickly. It also has a very clever sequential turbocharger setup and a ‘FreeValve’ cylinder head that controls the valves via pneumatic actuators, negating the need for a conventional camshaft.
Makes you wonder - how is Koenigsegg going to top this level of engineering geekery?

Fun fact about this car: Mechanically speaking, this is the world’s first rear/mid engined front wheel drive (RF layout) production car since the Dymaxiom, Maroon car and the Gregory sedan prototypes which were made from 1930s to 1947.
This is probably the weirdest engine I have ever seen in my life, its piston speed is as Jason said 26.5m/s that is the exact same as a Formula 1 engine, this is insane, you have F1 piston speeds in a road car!
And the pistons are way bigger than an F1 engine
I have an urge to swap this into my miata
Ahem I believe Christian Von Koenigsegg will want a word with you about that first….and hes got a team of lawyers with him from what I see
This project would have my full support, hybrid or not.
That turbo setup with the individual valve ports is super unique, I’ve never seen something like that outside this never-raced Alfa Romeo engine from the 80s.
How are you supposed to service this thing?
I think Koenigsegg would do that easily enough for you
Article need to be edited, the Gemera uses Koenigsegg Direct Drive, similar system used in the Regera, not 7-clutch gearbox.
