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.

Suzuki S-Cross concept (2012) first pictures

Suzuki will launch the S-Cross crossover in late 2013, as a Golf-sized 4x4 to succeed the SX4. It's a bigger vehicle than today's SX4 and marks the end of the collaboration with Fiat which spawned the Sedici. The Italians will now turn to inhouse partner Jeep while Suzuki develops the new S-Cross itself.

Ford Iosis X concept

With an abundance of small SUVs entering the European market, Ford has been conspicuously absent from this segment, something that the Iosis X will hope to quell. Using the same 'kinetic design' theme as the Iosis concept from last year, the Iosis X puts a coupe-like window graphic and roofline upon thick sills, similar in this respect to the Opel Antara concept. But while Opel will have their model on the road imminently, those wanting the Ford equivalent will have to wait until early 2008 for the forms to be toned down and put in showrooms.
