More than 20 years in development, INFINITI’s new four-cylinder turbocharged gasoline VC-Turbo engine represents a major breakthrough in internal-combustion powertrain technology. VC-Turbo technology signifies a new chapter in the story of the internal combustion engine – engines are no longer limited by a fixed compression ratio. The ingenuity of VC-Turbo engine technology lies in its ability to transform itself and seamlessly raise or lower the height the pistons reach. As a consequence, the displacement of the engine changes and the compression ratio can vary anywhere between 8:1 (for high performance) and 14:1 (for high efficiency). The sophisticated engine control logic automatically applies the optimum ratio, depending on what the driving situation demands.
