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.

I wonder why they chose to use a driveshaft to drive the front wheels. In my mind it would make more sense to power the rear wheels with the combustion engine and put the two big electric motors at the front.
Maybe they want to more accurately and quickly vector the torque at the rear wheels?
They must have learned a lot since the “Qamfree” venture launched in China. Would be neat to know what the knowledge sharing actually looked like.
Impressive as hell.
Reading the headline I was “oh cool, they look at the old engines”… Didn’t the CC have like 650hp in the mid-90ies?
I want this engine and it’s A.I. engine management in my Rx7 Turbo II. The weight distribution would be the same or better.
