2012 Mercedes A-Class: First Sketch

Mercedes A-Class - First Sketch This may well be the first sketch of the 2012 Mercedes A-Class, but with the 2012 A-Class likely to surface at the Shanghai Motor Show next month it seems highly likely we’re in for a run of ‘leaked’ information on the new baby Mercedes.

The famous London taxi design has come in for much criticism from cabbies for its unrefined drive, patchy reliability and questionable cabin ergonomics.

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.
