Nissan previews Resonance Detroit show concept

Nissan has teased its Resonance crossover concept ahead of its official debut next week in Detroit. The image of the concept, which Nissan says is the latest in a series of crossover designs "fusing bold styling with a hybrid-electric powertrain," shows a sharp flowing character line running along the side as well as the L-shaped LED rear lamps that can be found on the Nissan Juke. We can also see that the Resonance features a floating roof, created by the C-pillar not joining up to the roof but curving down to leave a break to the roof, giving the impression that it is floating over the rear window.

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.
