Tech has been in F1 for a while. Neat to see it working it's way into road cars. Ultra high RPM 4 cycle engines.
With torque based race engines now, I would think the need for a ultra fast valve train has diminished.
Koenigsegg has developed a camless engine. It uses pneumatic actuators to open and close valves. The benefits seem pretty impressive. Makes me wonder how an Ecoboost 3.5L would run with this technology?
