Safety

Using vehicle speed sensors and seat sensors, smart airbags in the Passport deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Passport’s side airbags will shut off if a child is leaning against the door. The RDX’s airbags don’t have smart features and will always deploy full force.

Both the Passport and the RDX have standard driver and passenger frontal airbags, side-impact head airbags, front wheel drive, 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, rearview cameras, available all wheel drive, blind spot warning systems, rear parking sensors and rear cross-path warning.

Warranty

There are almost 4 times as many Honda dealers as there are Acura dealers, which makes it much easier should you ever need service under the Passport’s warranty.

Reliability

The engine in the Passport has a single overhead cam for simplicity. The engine in the RDX has dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Honda vehicles are more reliable than Acura vehicles. J.D. Power ranks Honda 12th in reliability, above the industry average. With 19 more problems per 100 vehicles, Acura is ranked 20th.

Engine

The Passport’s 3.5 SOHC V6 produces 8 more horsepower (280 vs. 272) than the RDX’s 2.0 turbo 4 cyl.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the Passport’s fuel efficiency. The RDX doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Honda Passport uses regular unleaded gasoline. The RDX requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

The Passport has 2.4 gallons more fuel capacity than the RDX (19.5 vs. 17.1 gallons), for longer range between fill-ups.

Brakes and Stopping

For better stopping power the Passport’s brake rotors are larger than those on the RDX:

Rear Rotors

Tires and Wheels

For better traction, the Passport has larger standard tires than the RDX (245/50R20 vs. 235/55R19). The Passport Touring/Elite’s tires are larger than the largest tires available on the RDX (265/45R20 vs. 255/40R20).

The Passport Sport/EX-L’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the RDX’s standard 55 series tires.

For better ride, handling and brake cooling the Passport has standard 20-inch wheels. Smaller 19-inch wheels are standard on the RDX.

Suspension and Handling

For a smoother ride and more stable handling, the Passport’s wheelbase is 2.6 inches longer than on the RDX (110.9 inches vs. 108.3 inches).

For better handling and stability, the average track (width between the wheels) on the Passport is 2.6 inches wider in the front and 2.1 inches wider in the rear than the track on the RDX.

Passenger Space

The Passport has 11.9 cubic feet more passenger volume than the RDX (115.9 vs. 104).

The Passport has .5 inches more front headroom, 4.1 inches more front hip room, 2.3 inches more front shoulder room, 1.8 inches more rear headroom, 1.2 inches more rear legroom, 7.4 inches more rear hip room and 5.3 inches more rear shoulder room than the RDX.

For enhanced passenger comfort on long trips the Passport’s rear seats recline. The RDX’s rear seats don’t recline.

Cargo Capacity

The Passport has a much larger cargo volume than the RDX with its rear seat up (41.2 vs. 31.1 cubic feet).

Towing

The Passport’s standard towing capacity is much higher than the RDX’s (3500 vs. 1500 pounds). Maximum trailer towing in the Acura RDX is only 1500 pounds. The Passport offers up to a 5000 lbs. towing capacity.

Ergonomics

The Passport Touring/Elite has a 115-volt a/c outlet, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The RDX doesn’t offer a house-current electrical outlet.
