How Koenigsegg’s 3-cylinder engine makes 600 horsepower

Posted by in category: engineering

The Koenigsegg Gemera is a four-seat hypercar that can do 0–62 mph in a claimed 1.9 seconds, but perhaps the most remarkable thing about this Swedish rocket ship is its 2.0-liter twin-turbocharged inline-3, which makes a staggering 600 horsepower (plus 443 pound-feet of torque).

Jason Fenske at Engineering Explained has the details on how Koenigsegg extracted so much power from such a small engine. It starts with the cylinders. There may not be many of them, but they are pretty big. They’re actually larger than the cylinders in Koenigsegg’s 5.0-liter V8, Fenske noted.

Koenigsegg’s new Gemera makes over 1700 horsepower, with close to a third of that figure coming from a 3-cylinder engine.
