The Koenigsegg Gemera Hypercar

The Koenigsegg Gemera is a four-seat hypercar that can accelerate from 0 to 100 km / h in 1.9 seconds. The most notable thing about this Swedish rocket, however, is the 2.0-liter in-line 3 turbo engine, which delivers a breathtaking 600 hp.

Engineering Explained’s Jason Fenske has the details on how Koenigsegg drained so much power from such a small engine. Start with the cylinders. There may not be many, but they are quite large. They are actually larger than the cylinders in Koenigsegg’s 5.0-liter V8, Fenske noted.

Koenigsegg also rated this engine up to 11. His twin turbines generate a lot of propulsion (29 psi), but the triple cylinder can accelerate like a normal engine. The maximum is 8,500 rpm and is considered a red line. This means that the pistons are moving very quickly. According to Fenske, the speed is almost the same as the current Formula 1 engines.

The 3-cylinder engine also uses Koenigsegg’s tubeless FreeValve system. This enables better control over valve operation and offers more power generation options. The disadvantages are complexity, cost (FreeValve will no longer be seen in a Ford Fiesta or Mini Cooper) and the additional power required to drive pneumatic actuators to open and close valves.

With FreeValve, however, the complicated 3-cylinder twin turbo setup worked. Each cylinder has a set of exhaust valves for each turbo. With FreeValve, one of these valves can remain closed at less RPM, which means that only one turbo is used. This allows the single turbo to be wound up more quickly. At higher speeds, the second valve opens and the exhaust gases are directed to both turbos.

The three-cylinder engine is installed behind the rear seats and operates with two electric motors totaling 1,700 hp. Part of this power can be transferred to the front wheels via a torque tube and clutch assembly, which will drive the Gemera four-wheel drive. The 16.6 kWh battery saves energy and enables about 30 miles of electric driving, as measured by the European test cycle.

Gemera production is limited to 300 units at an undetermined price. This is even exclusive compared to many other super sports cars, but it will still make the Gemera the most productive Königsegg to date.
