 Pneumatic valve springs gave Renault an advantage with its turbocharged engines, often said to be one of the most powerful.However, reliability and poor handling of their chassis kept the cars from success until 1989, when Renault provided Williams with a new V10 engine that began a winning streak.Pneumatic valve springs are also found in several Moto GP motorcycle engines, debuting in 2002 with the Aprilia RS Cube.
