Infiniti's VC-Turbo S.U.V.: A 'Leap Ahead' in Efficiency The technology, displayed by Nissan's Infinity luxury brand and called VC-Turbo, would make it possible for the first time in a production-ready vehicle to vary the compression ratio in the engine's combustion chambers while the car is being driven. It matters because the compression ratio — the relationship between the smallest and largest volume in an engine cylinder during the piston stroke — is among the factors that determine the fuel efficiency and the power of an internal-combustion motor. A lower compression ratio is desirable when the goal is to use less fuel and to produce fewer greenhouse gas emissions. A higher ratio is what you want when the purpose is to drive fast, temporarily ignoring fuel economy and environmental concerns. Engine experts consider Infiniti's breakthrough a potential big deal.
