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.

BMW ‘i’ Brand 46 dealer network for i3 & i8

Each i-Brand centre will have specialist technical capabilities so they can work on the i range of cars and their high-voltage batteries, and BMW say there will also be a wider network for servicing and maintenance of their electric cars. The first of the -Brand cars to go on sale from BMW will be the city car i3 (which will also come with the option of a range extender engine to make it truly useful) later in 2013 followed by the i8 supercar. Prices are yet to be confirmed even for the i3, but we’re expecting the i3 to start around the £35k mark and the i8 – when it does arrive – costing something closing in on £100k.

Goodwood FoS really does create sales for supercar makers

Is the Goodwood Festival of Speed just an excuse for petrolheads to gather, or do supercar makers actually see sales rise as a result? If you’re a real petrolhead, there really is no better car show on earth than the Goodwood Festival of Speed (which starts this weekend). Yes, other car shows offer some of what Goodwood does – Villa D’Este, Pebble Beach and Salon Prive are all very good – but none have the depth of petrolhead goodness you’ll find on offer at Goodwood.
