I’m enthralled by the Koenigsegg TFG. That would be the Tiny Friendly Giant engine that the Swedish automaker has created for its new Gemera super sedan. It’s a twin-turbocharged 2.0-liter three-cylinder engine that produces 600 horsepower. How does such a small wonderful thing make 300 hp per liter? Our friend Jason Fenske is here to explain the engineering behind it all.
Not only is the power amazing, but so is the technology that builds it up. The TFG engine doesn’t have a camshaft. It uses Freevalve technology where the intake and exhaust valves open independently through pneumatic actuators. Timing, lift, duration, etc, all of that is electronically controlled and infinitely adjustable.
The TFT is a technical marvel and I love it. To learn a whole lot more about it, click play on the Engineering Explained video above.
