How does Koenigsegg Freevalve work?
By doing away with the camshaft and replacing it with a compact actuator above each tappet, the Freevalve system allows each valve to be individually controlled. Most modern engines use twisting cam drive pulleys to open and close the valves earlier or later to help emissions.
What is Freevalve engine?
The Freevalve concept, also known as fully variable valve actuation, offers the unique ability to have independent control of the intake and exhaust valves in an internal combustion engine. This allows a greater degree of control over the engine which in turn provides significant performance benefits.
What is Koenigsegg free valve technology?
Freevalve technology (which Koenigsegg off-shoot Freevalve explains in detail here) controls the opening and closing of its valves with pneumatic actuators instead of with a turning camshaft.
Who makes engines for Koenigsegg?
Ford motor
The first Koenigsegg engine appeared in the CCX, and 20 to 25 percent of its parts came from the Ford motor. Today’s Koenigsegg engines include only about 5 percent Ford engine parts. The Swedish automaker also now produces multiple engines, including naturally aspirated and twin-turbocharged varieties.
Is Koenigsegg Gemera Electric?

How does a camshaft work?
A camshaft is a rod which rotates and slides against a piece of machinery in order to turn rotational motion into linear motion. This change of motion is accomplished by the camshaft moving further and closer from the axis of rotation as the camshaft is pushed by the machinery.

What fuel does the Koenigsegg Gemera use?
The engine can run on both E85 bio fuel and gasoline and has a titanium exhaust system manufactured by Akrapovič. Being the first all-wheel-drive model, the Gemera has all-wheel steering and torque vectoring.
How does the Koenigsegg FreeValve engine work?
If you can imagine an engine free of the mechanical constraints of a steel camshaft (or four), you have the basics of the Koenigsegg Freevalve engine. As opposed to a camshaft dictating valve position, each valve has its own actuator controlling the valve position and timing.
What are the benefits of Freevalve engines?
The benefits of Freevalve are undeniable, however, granting an engine massive amounts of additional flexibility to operate at high levels under a wide variation of conditions. Things like fuel quality, fuel type, air temp, air quality and so many other factors can be adjusted for.
How does the Koenigsegg direct drive transmission work?
The Koenigsegg Direct Drive Transmission removes the traditional gearbox from the car. As the gearbox is responsible for both added weight and efficiency losses, any chance to remove this double-negative is welcome.
What’s the most interesting thing about the Koenigsegg TFG?
And perhaps the most interesting thing about the car is its engine. Koenigsegg calls the engine the Tiny Friendly Giant, or TFG for short, and it’s an apt name.
