Christian von Koenigsegg's namesake company is small, but it builds some of the most advanced supercars in the world. The Regera, for example, is a 1500-horsepower plug-in hybrid that doesn't have a gearbox. It's incredible.
What a lot of people don't know, though, is that Koenigsegg has a sister company called Freevalve. And Freevalve is working to sell the world's first camless engine. By getting rid of camshaft and the throttle body, Koenigsegg says you get better power, torque, efficiency, fuel economy, and emissions. It's an engine that can run on multiple fuels, run as a two-stroke, use the Atkinson Cycle, and shut down cylinders independently. It's a marvel of engineering and is the way of the future for the internal combustion engine.
All that sounds awesome, but how does that actually work? Obviously, it's pretty complicated, but our favorite car nerd, Engineering Explained does a great job of breaking it all down. Check out his explanation below and get ready to have your mind blown.

Well why not... it’s a matter of computerized solenoid control of the valves. Once that is done, no mechanical linkage to open the valves is needed, and no throttle or throttle body is needed. Why wasn’t this seen decades ago — was there a problem with engineering actuators that were robust enough or economical enough? With what-ifs, one could even envision vacuum tube technology driving the valves with an analog control system, meaning this could have been done in the early 20th century. So why not then, why now?
Very cool. I wonder how long the actuators can endure that hostile environment?
I suppose it could have short push rods to isolate the actuators from the intense heat.
This was tried in the past. The issue was mainly CPU horsepower, and external hydraulic pumps for the valve actuators.
With the advent of direct gas injection, high pressure rail diesel injector design, and stupid fast microcontrollers, this would be very feasible technology.
The automotive business is famously cautious, even stodgy, when it comes to engine innovations. The immense cost and risk involved require years of testing and prototyping and tight control over budgets and pricing.
Sounds awesome??? Without cams it's going to sound like a squeaky rat with his nads caught in a vice, right? No thanks, give me my big cams (which have the side benefit of driving libs mad).
As long as the electrical power is good and you do not get hit by EMP, all is well!

Gimme a chopped ‘34 Ford coupe, full-fendered, with a nice Flathead with Edlebrock heads and Tri-cards.
Didn't quite have the same roar, though, as the nearly 5,000 shaft horsepower engines for the Chinooks.

I would prefer their car, the Koenigsegg One:1
Incredible thing. 273 mph top end.
You need to see the “Hitler discovers they’ve put a Wankel engine in his car” video.

The other basic skill everyone should know is how to post an image.

There is a lot more there than you probably need.
