Safety

For enhanced safety, the front and rear seat shoulder belts of the Lexus UX Series have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW X4 doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Lexus UX Series are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X4 doesn’t offer height-adjustable seat belts.

The UX Series has standard Secondary Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The X4 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the UX Series and the X4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available blind spot warning systems, rear parking sensors and rear cross-path warning.

Warranty

Lexus’ powertrain warranty covers the UX Series 2 years and 20,000 miles longer than BMW covers the X4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X4 ends after only 4 years or 50,000 miles.

Regenerative brakes improve the UX 250h’s fuel efficiency by converting inertia back into energy instead of wasting it. The X4 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 X4 requires premium, which can cost 20 to 55 cents more per gallon.

Transmission

The UX Series has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The X4 doesn’t offer a CVT.

Suspension and Handling

For better maneuverability, the UX Series’ turning circle is 5.8 feet tighter than the X4’s (34.2 feet vs. 40 feet).

Chassis

The Lexus UX Series may be more efficient, handle and accelerate better because it weighs about 700 to 850 pounds less than the BMW X4.

The UX Series is 10.5 inches shorter than the X4, making the UX Series easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The UX Series has a much larger cargo volume than the X4 with its rear seat up (21.7 vs. 18.5 cubic feet).

To make loading groceries and cargo easier when your hands are full, the UX Series’ liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The X4 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than BMW. J.D. Power ranks Lexus third in service department satisfaction. With a 14% lower rating, BMW is ranked 8th.

Ergonomics

The UX Series has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The X4 doesn’t offer a remote starting system.

Model Availability

The UX Series is available in both front-wheel drive and four-wheel drive configurations. The X4 doesn’t offer a two-wheel drive configuration.
