Is this a tease for the 2015 Volvo XC90?

We’re not entirely sure what to make of a new tease video from Volvo that’s dropped in to our inbox.

The video shows an ‘outdoor’ man walking form a vehicle at the edge of a lake towards a lighthouse  and as the shot pulls out we can see the vehicle he’s walking away from, and it’s clearly an SUV or Crossover.

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.
