PHOENIX — When the next-generation Infiniti QX50 crossover arrives next year as a 2019 model, it will be powered by a 2.0-liter turbocharged four-cylinder engine introducing a technology never seen before in a regular production vehicle: variable compression.
Under development at Nissan for 20 years, the Variable Compression – Turbo — VC-T engine — has a device that changes the distance the pistons travel in their cylinders by as much as 6 mm, or about a quarter of an inch.
