how is Koenigsegg going to top this level of engineering geekery?

Getting 150-200bhp from a 3-cylinder engine is fairly normal these days, but how about triple that figure?! Koenigsegg recently released the Gemera – the first ever four-seater hypercar – and while it develops 1,700bhp in total, the most remarkable thing is that 600bhp of that comes from a 3-cylinder engine. As always, Christian von Koenigsegg has been as innovative as ever.


The  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.

Koenigsegg - This Is How The Koenigsegg Gemera's Inline-Three Develops 600bhp - Supercars and Hypercars
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  going to top this level of engineering geekery?

The Koenigsegg Gemera is the world's most wickedly weird hybrid ...
