Buy Dad a piece of the famed Mazda Laguna Seca Raceway

You might never get the chance to dominate the Corkscrew at Mazda Raceway Laguna Seca in Monterey, Calif., the way Nicky Hayden and Alex Zanardi did, but you can still make your mark on the famous stretch. A spectator terrace is being constructed atop the turn, and racing fans can buy a brick etched with a name or personal message to sit on the walk of fame. It sure beats a tie for Dad on Father's Day, and all of the money raised will go to improving the raceway.

We’re told it’s the same high-revving engine that powered the outgoing RS4, albeit spruced up with the latest Ingolstadt know-how.

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. Engineers have long understood the benefits of changing valve opening and closing times to tweak an engine's power and emissions performance, depending on the need for power or parsimony.Valves are an engine's nose and mouth – it inhales through inlet valves and exhales through exhaust valves.
