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.

You may not have heard of BYD, but it’s the world’s biggest rechargeable battery manufacturer. It also has the largest global market share for mobile phone chargers and keypads. Interesting stuff, but why is this is of interest to MSN Cars?

Film Friday: A Wonderful New World of Fords has descended from the heavens!

In a day when every automaker seems to be eager to latch on to the smallest details -- a few pounds of weight shaved here and there, some silly feature designed to keep you and your family protected in an accident, a flashier infotainment setup -- to sell their product, this 1960 Ford spot is a breath of fresh air. There's none of this oh-so-carefully hedged “our cars are pretty OK!” nonsense in this spot for the 1960 Thunderbird, Falcon and Galaxie. There's nary a world about fuel economy (OK, one mention -- the Falcon supposedly gets up to 30 mpg).
