Koenigsegg succeeded in creating a super powerful three-cylinder engine nicknamed the ‘Friendly Giant’ (TFG). This unit is the centerpiece of the Gemera hybrid ‘megacar’ which is scheduled to go into production in 2022. With a capacity of just 2,000 cc, power output is claimed to reach 608 PS/600 Nm. Sure, there’s twin-turbo support, but technology in the interior also plays a big role in the TFG’s greatness.
If you look at the contents of the TFG cylinder head, you will definitely not find camshafts like car engines in general. It follows the latest Freevalve technology so that each valve can move automatically. The system uses air pressure to push the valves, and then the open position is taken by electro-hydraulics – which also slows the movement of the valve.
The method provides many benefits for performance and efficiency. Air can enter the combustion chamber more easily because the valve can open quickly – without adjusting the cam profile. The engine’s brain (ECU) controls each valve. It provides flexibility in adjusting intake and exhaust air timing from intake to exhaust, as well as how long and how far the valve will open.

The change was definitely able to create a different perspective machine. Imagine being like a person who has mood swings but can be controlled when needed. Sometimes it can give bad behavior like a worn competition camshaft, sometimes it can be as tame as a car without oil. One cylinder can also be fully deactivated to make it more economical.
Not forgetting the technology used to control the two turbo rounds. Although only three cylinders, the turbo has two units that move in steps. The distribution of rotating shifts instead of relying on a valve in the turbo pipe. Three of the six exhaust valves are dedicated to driving each turbine, and the free valve is responsible for dividing the blasts. Launches the YouTube channel Engineering Explained, this exhaust gas loop is converted to an additional air pressure of up to 29 psi.
The Freevalve and twin-turbo combination provides incredible output for the 2,000 cc three-cylinder engine. As mentioned earlier, the standard engine extraction can produce 608 PS and a peak torque of 600 Nm. Amazing isn’t it? Gemera doesn’t stop there when it comes to energy. Assisted by three electric motors, the general excavation can carve out 1,724 PS and a torque of 3,500 Nm. That is why it is included in the megacar category.
Back to TFG, even though it has the potential to be powerful it doesn’t mean it is wasteful or polluting. Fuel consumption is claimed to be 15-20 percent more efficient than a 2,000 cc injection engine. Emissions are 60 percent cleaner than a conventional three-cylinder engine with camshaft. It is even referred to as CO2 neutral if you are using second generation alcohol based fuel. (Krm/Odi)
