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.

Ford F-150 SVT Raptor gets turned into 'The Beast'

Looks like we've got ourselves a good ol' fashioned truck horsepower war brewing. Hot on the heels of the debut of the Chevrolet Silverado-based Reaper by Lingelfelter and the Callaway-tuned Chevrolet Silverado, German tuner Geiger has brought out their version of the Ford F-150 SVT Raptor dubbed "The Beast." Apparently, the company felt that the standard Raptor just didn't produce enough power, but their take on the already mental truck is slightly different from Hennessey's approach. Geiger has added a 2.9-liter supercharger to the 6.2-liter V8, bringing the horsepower output up from 411-hp to 572-hp.
