Compare the2025 Lexus NXVS 2025 BMW X3

For enhanced safety, the front seat shoulder belts of the Lexus NX 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 X3 doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the NX are reminded to check the back seat if they opened the rear door before starting out. The X3 doesn’t offer a back seat reminder.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Lexus NX achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The BMW X3 has not been tested.

Both the NX and X3 have rear cross-traffic warning, but the NX has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The X3’s Cross Traffic Warning doesn’t automatically brake.

The NX’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The X3 doesn’t offer a driver alert monitor.

Both the NX and the X3 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The Lexus NX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2025 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated moderate overlap front crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The X3 has not yet been evaluated by the IIHS for 2025.

Lexus’ powertrain warranty covers the NX 2 years and 20,000 miles longer than BMW covers the X3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X3 ends after only 4 years or 50,000 miles.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Lexus above average in initial quality. With 32 more problems per 100 vehicles, BMW is rated below average.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the statistics that show that Lexus vehicles are more reliable than BMW vehicles. J.D. Power ranks Lexus first in reliability, above the industry average. With 55 more problems per 100 vehicles, BMW is ranked 9th.

From surveys of all its subscribers, Consumer Reports’ March 2025 Auto Issue reports that Lexus vehicles are more reliable than BMW vehicles. Consumer Reports ranks Lexus second in overall reliability. BMW is ranked 8th.

On the EPA test cycle the NX running on electricity gets better mileage than the X3:

On the EPA test cycle the NX running its gasoline engine gets better mileage than the X3:

The NX 450h can travel with zero emissions for 37 miles. The X3 can’t move without running its internal combustion engine.

The NX offers an available 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 X3 doesn’t offer a CVT.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the NX can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The X3 doesn’t offer run-flat tires.

For better maneuverability, the NX’s turning circle is 2 feet tighter than the X3’s (38 feet vs. 40 feet).

The Lexus NX may be more efficient, handle and accelerate better because it weighs about 50 to 500 pounds less than the BMW X3.

The NX is 3.7 inches shorter than the X3, making the NX easier to handle, maneuver and park in tight spaces.

The NX has .8 inches more front legroom and .3 inches more rear headroom than the X3.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than BMW. J.D. Power ranks Lexus second in service department satisfaction. With a 24% lower rating, BMW is ranked 10th.

The NX’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The X3 doesn’t offer an easy entry system.

The NX’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The X3 does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the NX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the X3 only has an intermittent setting, so in a hard rain visibility isn’t as good.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The NX offers available headlight washers to keep headlight output high. The X3 doesn’t offer headlight washers.

The NX has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the X3.

The NX is available in both front-wheel drive and four-wheel drive configurations. The X3 doesn’t offer a two-wheel drive configuration.

Consumer Reports® chose the Lexus NX as its “Top Pick,” the highest scoring vehicle in its category, based on reliability, safety and performance.

The Lexus NX outsold the BMW X3 by 3056 units during 2024.
