Safety

To help make backing safer, the RDX’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Macan doesn’t offer a cross-path warning system.

Both the RDX and the Macan have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive, blind spot warning systems and around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the RDX its highest rating: “Top Pick Plus” for 2019, a rating granted to only 46 vehicles tested by the IIHS. The Macan has not been tested, yet.

Warranty

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

There are over 42 percent more Acura dealers than there are Porsche dealers, which makes it easier should you ever need service under the RDX’s warranty.

Engine

The RDX’s 2.0 turbo 4-cyl. produces 24 more horsepower (272 vs. 248) and 7 lbs.-ft. more torque (280 vs. 273) than the Macan’s standard 2.0 turbo 4-cyl.

To lower fuel costs and make buying fuel easier, the Acura RDX uses regular unleaded gasoline (premium recommended for maximum performance). The Macan requires premium, which can cost 20 to 55 cents more per gallon.

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 Macan 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 a seven-speed automatic is available for the Macan.

Tires and Wheels

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 Macan’s standard 60 series front tires.

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

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 Macan doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

For greater off-road capability the RDX has a greater minimum ground clearance than the Macan (8.2 vs. 8 inches), allowing the RDX to travel over rougher terrain without being stopped or damaged.

Chassis

The Acura RDX may be more efficient, handle and accelerate better because it weighs about 250 to 300 pounds less than the Porsche Macan.

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

Cargo Capacity

The RDX has a much larger cargo volume with its rear seat up than the Macan with its rear seat up (31.1 vs. 17.6 cubic feet). The RDX has a much larger cargo volume with its rear seat folded than the Macan with its rear seat folded (79.8 vs. 52.9 cubic feet).

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

Ergonomics

The RDX 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 Macan doesn’t offer a remote starting system.

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 Macan.

The RDX Advance has a standard heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Macan doesn’t offer a heads-up display.

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

While driving with high beams on, sensitive light sensors standard on the RDX detect other vehicles which could be blinded and automatically switch to low beams. The Macan doesn’t offer automatic dimming high beams.

Model Availability

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

Economic Advantages

According to The Car Book by Jack Gillis, the RDX is less expensive to operate than the Macan because it costs $173 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the RDX than the Macan, including $91 less for a water pump, $723 less for a muffler, $6 less for a starter, $169 less for fuel injection, $308 less for front struts and $824 less for a timing belt/chain.

Recommendations

The Acura RDX outsold the Porsche Macan by almost three to one during 2018.
