Terry,
          Renault developed a system using pneumatics. However what most people
don't understand is that they are replacing the valve springs with "air
bags" NOT ACTUATING
THE VALVES. To my knowledge all current F1 engines have pneumatic valve trains.
This is why they are able to pull the massive rpm they use.
