Tomorrow’s world: Fiat's MultiAir engine tech

By Jesse Crosse Motor Industry 14 October 2009 16:50 Fiat this year launches what it claims is a big step forward in variable valve timing: MultiAir. It's the first time that a manufacturer has made a properly variable valve system a production reality, and will slowly be rolled out across most of Fiat's and Alfa's car ranges.How does Fiat's MultiAir vary from existing variable valve timing (VVT) systems?Current VVT systems rely on mechanical systems to open and close the valves.
