Infiniti will debut a new engine next month at the 2016 Paris Motor Show (Mondial de l’Automobile). The automaker spent more than 20 years developing Variable Compression-Turbocharged or VC-T technology for full production.
These variable compression ratio engines signify a brand milestone.
“VC-T technology is a step change for Infiniti,” said Roland Krueger, President of Infiniti Motor Company.
Krueger underscored the importance of the engines to Infiniti and their customers. One of the automaker’s primary goals in developing VC-T technology was to increase overall performance and capability.
“This technological breakthrough delivers the power of a high-performance 2.0-liter turbo gasoline engine with a high level of efficiency at the same time,” he said. Variable Technology
Infiniti’s VC-T engines are not bound by a fixed compression ratio. Instead, they can determine when to raise or lower the height of the piston’s reach, changing engine displacement and ultimately varying compression ratio. Depending on the change, Infiniti’s VC-T engine can operate anywhere between 8:1 (for high performance) and 14:1 (for high efficiency).

Similar to how variable cam timing works, the vehicle automatically calculates and applies the optimum ratio, based on the driving environment at hand. Infiniti’s VC-T engines ar...
