Koenigsegg Gemera: The 2,300 HP Mega-GT That Redefines the Supercar
by AutoExpert | 19 December, 2025
Supercars have always played by the same rule: big engine, big noise, big numbers. Ferrari, Lamborghini, Bugatti — they all swear by eight cylinders or more, sometimes way more. In this world, downsizing usually means compromise.
Koenigsegg didn’t get the memo.
Instead of chasing displacement, the brand decided to see how small a supercar engine could go without losing its edge. The result was the Gemera — a four-seat hypercar powered, at least in theory, by a three-cylinder engine.
Yes, three.
The engine is called the Tiny Friendly Giant, and it’s exactly as unhinged as it sounds. It’s a 2.0-liter twin-turbo three-cylinder that makes close to 600 horsepower on its own. Add Koenigsegg’s wild electric motor into the mix and total output jumps north of 1,300 horsepower. That’s enough to shove this family-friendly hypercar from zero to 60 mph in under two seconds.

The trick isn’t just boost. The engine doesn’t even use traditional camshafts. Instead, computers control each valve individually, letting the motor adapt in real time depending on how it’s being driven. It revs to 8,500 rpm, runs cleaner than you’d expect, and weighs about as much as a large American V-twin motorcycle.

The electric side is just as ridiculous. Koenigsegg’s “Dark Matter” motor produces around 800 horsepower by itself and sends power wherever it’s needed. The Gemera can run front-wheel drive, rear-wheel drive, all-wheel drive, gas, electric, or any combination in between — all without the driver thinking about it.
And somehow, it still has room for four people.

Ironically, buyers weren’t ready for something this different. Most customers chose the optional twin-turbo V-8 instead, which pushed Koenigsegg to pause plans for the three-cylinder version. But the company says the idea isn’t dead — just waiting for the right moment.
Whether it ever reaches full production or not, the Gemera already made its point. In the supercar world, bigger has always meant better. Koenigsegg proved that smarter might be even faster.
