Mexico-made Infiniti QX50 to feature groundbreaking variable compression engine
As the new Infiniti plant in Aguascalientes, Mexico is about to officially begin production of the new QX50, Nissan’s premium brand invited a few automotive journalists to drive early pilot-build versions of the SUV at the company’s test track in Phoenix, Arizona.
Such models, as well as those to be delivered to auto dealers starting somewhere in 2018, feature a 2.0-liter turbocharged four-cylinder engine with variable compression, a technology Nissan has kept under development 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, offering dramatic improvements in power and efficiency, says WardsAuto in its report.
It is expected to deliver a combined city-highway EPA-rated fuel economy gain of 27% over the QX50s’s outgoing 3.7-liter V-6. The VC-T engine is rated at 268 hp and 288 pound-feet of torque. That’ll allow the 2019 QX50 to reach 60 mph almost one second faster than its four-cylinder competitors.
