Infiniti’s potent 325-horsepower 3.7-liter V6 remains the sole engine; seven-speed automatic transmission; rear- or all-wheel drive.
Infiniti’s naming system can still prove problematic, even a year after its introduction. All SUVs and tall-wagons start with QX and the number that follows dictates its relative position in the lineup, not its engine displacement. So, the EX, which is essentially a Q40 wagon in wolf’s clothing, is now known as QX50. But other than the name adjustment and associated identification, there aren’t any changes to the package for 2015. That’s fine, though, since it retains the stout 325-horsepower 3.7-liter V6 as the sole engine choice. The only transmission remains the seven-speed automatic and the QX50 can be had in either rear- or all-wheel-drive. The interior of this five-seater is an inviting mix of organic shapes and attention to detail. Cloth seats are standard and leather an option. Of the technologies used, one of the most interesting is “self-healing” paint with the ability to, in a process that takes up to week depending on surface temperature, absorb small scratches and return the finish to a close-to-new condition. The optional “Around View Monitor” uses four cameras to show a top-down view of the EX as you’re backing into a parking spot: there’s no excuse for bruising your bumper now. As well, the optional lane-departure system warns when you’re unintentionally changing lanes and can help put the vehicle back where it belongs by automatically applying the left- or right-side brakes. The base model arrives well equipped with the usual assortment of power/luxury goodies including standard Bluetooth connectivity, dual-zone climate control and 18-inch wheels, while the maxed-out Journey trim adds the leather seats, power folding second-row seat and front-/rear sonar system to prevent bumping objects and other vehicles when navigating in close quarters.
