Infiniti’s Variable Compression-Turbo Charged (VC-T) Engine Promises Technological Breakthrough

Infiniti announced it will showcase, at the 2016 Paris Motor Show this month, its VC-T (Variable Compression-Turbocharged) engine which will be “a revolutionary next-step in optimizing the efficiency of the internal combustion engine.”

With more than 20 years in development, the VC-T engine is the world’s first production-ready variable compression ratio engine and, according to Infiniti, it’s the most advanced internal combustion engines ever built and it will represent a major innovation in internal-combustion powertrain technology.

The ingenuity of VC-T 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.

VC-T technology delivers multiple customer benefits including significantly reduced fuel consumption and emissions, greatly reduced noise and vibration levels; it is also lighter and more compact than comparable conventional engines.
