For enhanced safety, the front and rear seat shoulder belts of the Lexus RX 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 Mazda CX-50 doesn’t offer pretensioners for its rear 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 RX are reminded to check the back seat if they opened the rear door before starting out. The CX-50 doesn’t offer a back seat reminder.

With its standard Pre-Collision System with Pedestrian Detection, the Lexus RX is better at preventing collisions with pedestrians than the Mazda CX-50, according to the Insurance Institute for Highway Safety:

37 MPH Low beams	-32 MPH	-14 MPH
Warning Issued-Low beams	1.5 sec	1.4 sec

The RX has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The CX-50 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 RX and the CX-50 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, 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, driver alert monitors, available all wheel drive and around view monitors.

Warranty

The RX comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The CX-50’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Lexus’ powertrain warranty covers the RX 1 year and 10,000 miles longer than Mazda covers the CX-50. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the CX-50 ends after only 5 years or 60,000 miles.

The RX’s corrosion warranty is 1 year longer than the CX-50’s (6 vs. 5 years).

Reliability

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Mazda vehicles. J.D. Power ranks Lexus above average in initial quality. With 32 more problems per 100 vehicles, Mazda is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Mazda vehicles. J.D. Power ranks Lexus above average in long-term dependability. With 33 more problems per 100 vehicles in the first three years of ownership, Mazda is rated lower.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Lexus vehicles are more reliable than Mazda vehicles. Consumer Reports ranks Lexus first in overall reliability. Mazda is ranked 7th.

Engine

The RX has more powerful engines than the CX-50:

	Horsepower	Torque
RX 350h 2.5 DOHC 4-cylinder hybrid	246 HP	233 lbs.-ft.
RX 350 2.4 turbo 4-cylinder	275 HP	317 lbs.-ft.
RX 450h+ 2.5 DOHC 4-cylinder hybrid	304 HP
RX 500h F Sport Performance 2.4 turbo 4-cylinder hybrid	366 HP	406 lbs.-ft.
CX-50 2.5 DOHC 4-cylinder	187 HP	186 lbs.-ft.
CX-50 2.5 turbo 4-cylinder	256 HP	320 lbs.-ft.

As tested in Consumer Reports the RX 350h 2.5 DOHC 4-cylinder hybrid is faster than the Mazda CX-50 4 cyl.:

	RX	CX-50
Zero to 30 MPH	2.8 sec	3.4 sec
Zero to 60 MPH	7.8 sec	9.3 sec
45 to 65 MPH Passing	4.9 sec	5.7 sec
Quarter Mile	16 sec	17.2 sec
Speed in 1/4 Mile	89 MPH	84 MPH

Fuel Economy and Range

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

			MPG
RX
	AWD	350h 2.5 4-cyl. Hybrid	37 city/34 hwy
		500h 2.4 turbo 4-cyl. Hybrid	27 city/28 hwy
CX-50
	AWD	2.5 DOHC 4-cyl.	24 city/30 hwy
		2.5 turbo 4-cyl.	23 city/29 hwy

The RX 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 RX 350h/500h/450+’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 RX’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 (350 only). Mazda only offers an automatic engine start/stop system on the CX-50 Turbo.

The RX 350’s standard fuel tank has 1.9 gallons more fuel capacity than the CX-50 (17.8 vs. 15.9 gallons).

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus RX higher (7 out of 10) than the Mazda CX-50 (5 to 7). This means the RX produces up to 8 pounds less smog-producing pollutants than the CX-50 every 15,000 miles.

Transmission

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

The RX 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.

Brakes and Stopping

For better stopping power the RX’s brake rotors are larger than those on the CX-50:

	RX	RX F Sport	CX-50
Front Rotors	13.4 inches	15.7 inches	12.8 inches
Rear Rotors	13.4 inches	13.4 inches	12.8 inches

The RX’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 RX stops shorter than the CX-50:

	RX	CX-50
70 to 0 MPH	178 feet	181 feet	Car and Driver

Tires and Wheels

For better traction, the RX has larger tires than the CX-50 (235/60R19 vs. 225/65R17).

The RX’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 RX has standard 19-inch wheels. Smaller 17-inch wheels are standard on the CX-50. The RX’s optional 21-inch wheels are larger than the 20-inch wheels on the CX-50 Premium Plus/Turbo.

Suspension and Handling

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

The RX 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.

For a smoother ride and more stable handling, the RX’s wheelbase is 1.4 inches longer than on the CX-50 (112.2 inches vs. 110.8 inches).

For better handling and stability, the track (width between the wheels) on the RX is .1 inches wider in the front and 1.2 inches wider in the rear than the average track on the CX-50.

The RX 450h+ executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the CX-50 (26.8 seconds @ .65 average G’s vs. 28 seconds @ .58 average G’s).

For better maneuverability, the RX 500h F Sport Performance’s turning circle is .6 feet tighter than the CX-50’s (35.4 feet vs. 36 feet).

Chassis

As tested by Car and Driver, the interior of the RX 450h+ is quieter than the CX-50 2.5 Turbo:

	RX	CX-50
Full-Throttle	72 dB	80 dB

Passenger Space

The RX has .4 inches more front headroom, 3.1 inches more front hip room, 2.2 inches more front shoulder room, 3.9 inches more rear hip room and 2.9 inches more rear shoulder room than the CX-50.

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

Cargo Capacity

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

To make loading groceries and cargo easier when your hands are full, the RX Premium/Luxury/F Sport’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.

Towing

Standard Trailer Sway Control on the RX 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.

Servicing Ease

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.

Ergonomics

The RX 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 RX Premium/Luxury/500h F Sport’s standard 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 RX’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.

The power windows standard on both the RX and the CX-50 have locks to prevent small children from operating them. When the lock on the RX is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The CX-50 prevents the driver from operating the other windows just as it does the other passengers.

If the windows are left open on the RX the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Lexus service department.) The driver of the CX-50 can only close the windows from inside the vehicle, with the ignition on.

The RX’s standard Smart Access allow you to unlock the doors from any outside door handle, open the cargo door, and start the vehicle, all without removing the key from the pocket or purse. Advanced Keyless Entry and Start standard on the CX-50 doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The RX Luxury/500h F Sport offers available headlight washers to keep headlight output high. The CX-50 doesn’t offer headlight washers.

The RX’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 RX Premium/Luxury/F Sport has standard front air conditioned seats and the RX offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The CX-50 doesn’t offer air-conditioned seats in the rear.

Both the RX and the CX-50 offer rear vents. For greater rear passenger comfort, the RX 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 RX Hybrid offers an optional 115-volt a/c outlet in the cargo area, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The CX-50 doesn’t offer a house-current electrical outlet.

The RX Premium+/Luxury/F Sport’s optional Advanced Park can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Optional Remote Advanced Park will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The CX-50 doesn’t offer an automated parking system.

Model Availability

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

Economic Advantages

The RX will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the RX will retain 58.33% to 60.37% of its original price after five years, while the CX-50 only retains 53.88% to 56.04%.

Recommendations
