On the EPA test cycle the NX running its gasoline engine gets better mileage than the CX-50:

The NX 450h can travel with zero emissions for 37 miles. The CX-50 can’t move without running its internal combustion engine.

Regenerative brakes improve the NX 350h/450h’s fuel efficiency by converting inertia back into energy instead of wasting it. The CX-50 doesn’t offer a regenerative braking system.

Regardless of its engine, the NX’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip (not available 350h/450h+). Mazda only offers an automatic engine start/stop system on the CX-50 Turbo.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus NX higher (6 to 7 out of 10) than the Mazda CX-50 (3 to 7). This means the NX produces up to 24.5 pounds less smog-producing pollutants than the CX-50 every 15,000 miles.

An eight-speed automatic is available on the Lexus NX, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the CX-50.

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 CX-50 doesn’t offer a CVT.

The NX’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the CX-50 are solid, not vented.

The NX stops shorter than the CX-50:

For better traction, the NX has larger tires than the CX-50 (235/60R18 vs. 225/65R17).

The NX’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the CX-50’s standard 65 series tires.

For better ride, handling and brake cooling the NX has standard 18-inch wheels. Smaller 17-inch wheels are standard on the CX-50.

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 CX-50 doesn’t offer run-flat tires.

For superior ride and handling, the Lexus NX has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Mazda CX-50 has a rear torsion beam axle, with a semi-independent rear suspension.

The NX has standard front and rear stabilizer bars, which help keep the NX flat and controlled during cornering. The CX-50’s suspension doesn’t offer a rear stabilizer bar.

The NX offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The CX-50’s suspension doesn’t offer adjustable shock absorbers.

The NX 350 AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the CX-50 2.5 S (27.3 seconds @ .63 average G’s vs. 28 seconds @ .58 average G’s).

The NX has 2.7 inches more front hip room, .4 inches more front shoulder room, .4 inches more rear hip room and .4 inches more rear shoulder room than the CX-50.

For enhanced passenger comfort on long trips the NX’s rear seats recline. The CX-50’s rear seats don’t recline.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the NX. The CX-50 doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the NX’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The CX-50 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Standard Trailer Sway Control on the NX uses the Vehicle Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The CX-50 doesn’t offer electronic trailer sway control.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Mazda. J.D. Power ranks Lexus first in service department satisfaction. With a 41% lower rating, Mazda is ranked 11th.

The NX 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 CX-50 doesn’t offer a remote starting system.

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 CX-50 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 CX-50 does not have an oil pressure gauge.

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 CX-50 doesn’t offer headlight washers.

The NX’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the CX-50 Preferred/Premium/Turbo.

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 is only available on the CX-50 Select/Preferred/Premium/Turbo.

Both the NX and the CX-50 offer rear vents. For greater rear passenger comfort, the NX has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The CX-50 doesn’t offer rear air conditioning vents, only heat vents.

The NX 350h/450h+’s optional Advanced Park can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The CX-50 doesn’t offer an automated parking system.

The NX is available in both front-wheel drive and four-wheel drive configurations. The CX-50 doesn’t offer a two-wheel drive configuration.

Both are recommended, but 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 Mazda CX-50 by over two to one during 2022.
