Dubbed MultiAir, the hydraulically-actuated variable valve timing (VVT) technology was first announced as a concept two years ago, and offers a more controllable flow of air during the combustion cycle in comparison with mechanical VVT systems. Vastly reduced fuel consumption and emmissions plus significantly more power are claimed, and the technology is even more effective when used with a supercharger or a diesel engine. Read More
