Regenerative brakes improve the UX Series Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The QX50 doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Lexus UX Series uses regular unleaded gasoline. The QX50 requires premium, which can cost 20 to 55 cents more per gallon.

Tires and Wheels

The UX Series’ tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the QX50’s standard 55 series tires.

Suspension and Handling

For better maneuverability, the UX Series’ turning circle is 2.2 feet tighter than the QX50’s (34.2 feet vs. 36.4 feet).

Chassis

The Lexus UX Series may be more efficient, handle and accelerate better because it weighs about 350 to 500 pounds less than the Infiniti QX50.

The UX Series is 7.8 inches shorter than the QX50, making the UX Series easier to handle, maneuver and park in tight spaces.

Ergonomics

Standard smartphone integration for the UX Series allows the driver and passengers access to select programs on their smartphones, including playing internet radio stations and other connected activities without taking their eyes off the road or their hands from the wheel. The QX50 doesn’t offer factory integrated smartphone program access.
