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.

Vintage cars cross the auction block at Meadow Brook

An impressive array of gleaming classics crossed the block on Saturday at RM Auctions' Vintage Cars of Meadow Brook sale in a white linen event that showcased the grandeur and glamor of automaking in the Motor City in the early part of the Twentieth Century. The 16 annual auction, held on the eve of the Concours of America at Meadow Brook, is located about a half an hour north of Detroit on the grounds of a mansion where the widow of auto pioneer John Dodge one lived. Unlike the other RM auction, held in an convention hall on the other side of town in the spring, the Meadow Brook event carries an austere demeanor, and the automobiles roll with a similar vibe.

More Saab products coming, Muller says

Saab's new Dutch owner, Spyker Cars NV, intends to spin additional models off its new Phoenix platform after it yields a redesigned Saab 9-3. Saab dealers will receive the latest 9-3 in 2012, Spyker founder and Saab Automobile AB Chairman Victor Muller said Thursday at the CAR Management Briefing Seminars in Traverse City, Mich. The dealers, who have been starved for product as former owner General Motors attempted to sell or liquidate the brand, also will obtain a Cadillac-based 9-4X crossover when it goes into production in April 2011 in Mexico.
