The Acura RDX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The NX doesn’t offer a front passenger side knee airbag.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the RDX. But it costs extra on the NX.

Both the RDX and the NX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, 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 National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Acura RDX is safer than the Lexus NX:

	RDX	NX
	Driver
STARS	4 Stars	4 Stars
Neck Injury Risk	26%	34.2%
Neck Stress	262 lbs.	303 lbs.
Neck Compression	23 lbs.	41 lbs.
	Passenger
STARS	4 Stars	4 Stars
Chest Compression	.6 inches	.6 inches
Neck Injury Risk	30%	34.9%
Neck Stress	99 lbs.	136 lbs.
Leg Forces (l/r)	362/441 lbs.	413/450 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Acura RDX is safer than the Lexus NX:

	RDX	NX
	Front Seat
STARS	5 Stars	5 Stars
Hip Force	217 lbs.	238 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
HIC	124	134
Hip Force	462 lbs.	600 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	11 inches	13 inches
Spine Acceleration	39 G’s	48 G’s
Hip Force	704 lbs.	892 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Acura RDX is safer than the NX:

	RDX	NX
Overall Evaluation	GOOD	GOOD
Structure	GOOD	GOOD
	Driver Injury Measures
Head/Neck	GOOD	GOOD

Warranty

There are over 12 percent more Acura dealers than there are Lexus dealers, which makes it easier should you ever need service under the RDX’s warranty.

Reliability

J.D. Power and Associates rated the RDX first among compact premium suvs in their 2025 Initial Quality Study. The NX was rated second.

Engine

As tested in Motor Trend the Acura RDX is faster than the Lexus NX:

	RDX	NX 350h AWD	NX 350 AWD
Zero to 60 MPH	6.4 sec	7 sec	7.3 sec
Quarter Mile	14.8 sec	15.4 sec	15.5 sec
Speed in 1/4 Mile	94.7 MPH	89 MPH	92.1 MPH

Fuel Economy and Range

Both the RDX and the NX have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All RDXs have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. The NX 350h/450h+ doesn’t offer a way to disable start/stop.

To lower fuel costs and make buying fuel easier, the Acura RDX uses regular unleaded gasoline (premium recommended for maximum performance). The NX 350 AWD requires premium, which can cost on average about 84.9 cents more per gallon.

The RDX has 2.6 gallons more fuel capacity than the NX (17.1 vs. 14.5 gallons), for longer range between fill-ups.

The RDX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The NX doesn’t offer a cap-less fueling system.

Transmission

A 10-speed automatic is standard on the Acura RDX, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the NX.

Brakes and Stopping

The RDX stops much shorter than the NX:

	RDX	NX
60 to 0 MPH	116 feet	131 feet	Motor Trend
60 to 0 MPH (Wet)	129 feet	152 feet	Consumer Reports

Tires and Wheels

For better traction, the RDX A-Spec’s tires are larger than the largest tires available on the NX (255/45R20 vs. 235/60R18).

The RDX’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the NX’s standard 60 series tires. The RDX A-Spec’s tires have a lower 45 series profile than the NX’s optional 50 series tires.

For better ride, handling and brake cooling the RDX has standard 19-inch wheels. Smaller 18-inch wheels are standard on the NX.

The RDX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The NX doesn’t offer vehicle monitored tire inflation.

The RDX has a standard space-saver spare (not available on A-Spec) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the NX; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

For a smoother ride and more stable handling, the RDX’s wheelbase is 2.4 inches longer than on the NX (108.3 inches vs. 105.9 inches).

The RDX A-Spec handles at .83 G’s, while the NX 350 AWD pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

The RDX A-Spec executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the NX 450h+ Premium AWD (27 seconds @ .65 average G’s vs. 28.4 seconds @ .57 average G’s).

For greater off-road capability the RDX has a greater minimum ground clearance than the NX 350 F Sport Handling AWD (8.2 vs. 7.7 inches), allowing the RDX to travel over rougher terrain without being stopped or damaged. The RDX’s minimum ground clearance is .1 inch higher than on the NX (8.2 vs. 8.1 inches).

Chassis

The RDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The NX doesn’t offer active noise cancellation.

Passenger Space

The RDX has 1.3 inches more front headroom, .6 inches more front legroom, 3.4 inches more front shoulder room, 2.3 inches more rear legroom and 2.6 inches more rear shoulder room than the NX.

Cargo Capacity

The RDX has a much larger cargo volume with its rear seat up than the NX with its rear seat up (31.1 vs. 22.7 cubic feet). The RDX has a much larger cargo volume with its rear seat folded than the NX with its rear seat folded (79.8 vs. 46.9 cubic feet).

Towing

The RDX’s standard towing capacity is much higher than the NX’s (1500 vs. 0 pounds).

Ergonomics

The RDX’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the NX.

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

If the windows are left open on the RDX the driver can close all of them at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the NX can only close the windows from inside the vehicle, with the ignition on.

Consumer Reports rated the RDX’s headlight performance “Good,” a higher rating than the NX’s headlights, which were rated “Fair.”

The Acura RDX has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Lexus charges extra for Homelink® on the NX.
