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.
