There are few changes for the compact QX50, which saw its wheelbase stretched last year to increase rear-seat passenger space. Its 3.7-litre V6 engine provides the SUV with 325 horsepower, managed by a seven-speed automatic transmission and an all-wheel drivetrain. Only one version of the QX50 is offered, but with several option packages that add, among other things, an 11-speaker sound system, navigation and a host of electronic safety driving aids.
