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.

Mercedes GLA – the A-Class SUV – will arrive in production guise at Frankfurt

The production version of the Mercedes GLA Concept (pictured) will debut at Frankfurt 2013 It’s only three months since the new Mercedes GLA debuted at the Shanghai Motor Show as a concept, but it’s already close to arriving in production guise. In fact, it looks like the new GLA – based on the new Mercedes A-Class underpinnings – will arrive in production form at next month’s Frankfurt Motor Show, ahead of going on sale in early 2014. The new GLA is aimed squarely at the competition from the BMW X1 and Audi Q3, and if it delivers as well as the A-Class has it stands a very good chance of becoming the pick of the premium compact SUVs.
