#InfinitQx50

Miles per gallon can vary from driver to driver. We all know that. Now, Infiniti is trying out an engine that can vary its compression ration from scenario to scenario.

Miles per gallon is also a key spec for the new QX50, since the variable compression ratio tech is responsible for a claimed improvement in combined fuel economy – 35 percent for front-drive vehicles and 30 for all-wheel-drive units.

As is the usual case on first drives, I had no chance to verify those numbers – which, according to Infiniti, work out to 27 mpg combined with front-wheel drive and 26 mpg with all-wheel drive. Improved fuel economy is just part of the picture when it comes to variable compression, which is making its production debut in the 2019 Infiniti QX50.
