For enhanced safety, the front and second-row seat shoulder belts of the Acura MDX 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 BMW X5 doesn’t offer pretensioners for its second-row seat belts.

For enhanced safety, the front seat shoulder belts of the Acura MDX are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X5 doesn’t offer height-adjustable 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 MDX are reminded to check the back seat if they opened the rear door before starting out. The X5 doesn’t offer a back seat reminder.

Both the MDX and the X5 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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.

The Acura MDX has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned an “Acceptable” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and an “Acceptable” score in the revised pedestrian crash prevention test. The X5 is not even a standard “Top Safety Pick” for 2024.

Warranty

Acura’s powertrain warranty covers the MDX 2 years and 20,000 miles longer than BMW covers the X5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X5 ends after only 4 years or 50,000 miles.

Reliability

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Acura vehicles are more reliable than BMW vehicles. Consumer Reports ranks Acura fourth in overall reliability. BMW is ranked 9th.

Engine

The MDX Type S’ standard 3.0 turbo V6 produces 20 more horsepower (355 vs. 335) and 23 lbs.-ft. more torque (354 vs. 331) than the X5 40i’s standard 3.0 turbo 6-cylinder hybrid.

Fuel Economy and Range

On the EPA test cycle the MDX 3.5 SOHC V6 SH-AWD gets better fuel mileage than the X5 M50i (19 city/25 hwy vs. 16 city/22 hwy).

An engine control system that can shut down some of the engine’s cylinders helps improve the MDX’s fuel efficiency. The X5 doesn’t offer a system that can shut down part of the engine.

Both the MDX and the X5 have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All MDXs have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. A disable switch for start/stop is only offered on the X5 M50i.

To lower fuel costs and make buying fuel easier, the Acura MDX uses regular unleaded gasoline (premium recommended for maximum performance). The X5 requires premium, which can cost on average about 82.8 cents more per gallon.

The MDX 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 X5 doesn’t offer a cap-less fueling system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Acura MDX higher (5 out of 10) than the BMW X5 (3). This means the MDX produces up to 16.5 pounds less smog-producing pollutants than the X5 every 15,000 miles.

Transmission

A 10-speed automatic is standard on the Acura MDX, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the X5.

Brakes and Stopping

The MDX stops shorter than the X5:

	MDX	X5
70 to 0 MPH	170 feet	172 feet	Car and Driver
60 to 0 MPH	123 feet	127 feet	Motor Trend
60 to 0 MPH (Wet)	139 feet	142 feet	Consumer Reports

Tires and Wheels

The MDX 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 X5 doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The MDX Type S has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The MDX’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The X5 doesn’t offer a load leveling suspension.

For better handling and stability, the track (width between the wheels) on the MDX is 1.4 inches wider in the front and .7 inches wider in the rear than the average track on the X5.

The MDX Type S handles at .84 G’s, while the X5 xDrive40i pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the MDX’s turning circle is .8 feet tighter than the X5’s (40.5 feet vs. 41.3 feet).

For greater off-road capability the MDX Type S has a greater minimum ground clearance than the X5 (9.4 vs. 8.7 inches), allowing the MDX to travel over rougher terrain without being stopped or damaged.

Chassis

The Acura MDX may be more efficient, handle and accelerate better because it weighs about 450 to 550 pounds less than the BMW X5.

The MDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The X5 doesn’t offer active noise cancellation.

As tested by Car and Driver while at idle, the interior of the MDX Type S is quieter than the X5 xDrive40i (36 vs. 39 dB).

Passenger Space

The MDX has 1.8 inches more front legroom, 1.9 inches more front shoulder room, 1.1 inches more rear legroom and 2.2 inches more rear shoulder room than the X5.

Cargo Capacity

The MDX’s cargo area provides more volume than the X5.

	MDX	X5
Third Seat Folded	48.4 cubic feet	n/a
Third Seat Removed	n/a	33.9 cubic feet
Second Seat Folded	95 cubic feet	72.3 cubic feet

The MDX’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The X5’s tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

Payload and Towing

Standard Trailer Stability Assist on the MDX uses the Vehicle Stability Assist sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The X5 doesn’t offer electronic trailer sway control.

The MDX has a much higher standard payload capacity than the X5 (1173 vs. 827 lbs.).

The MDX has a higher maximum payload capacity than the X5 (1173 vs. 1030 lbs.).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Acura service is better than BMW. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 5% lower rating, BMW is ranked 7th.

Ergonomics

To improve rear visibility by keeping the rear window clear, the MDX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the X5 only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the MDX’s headlight performance “Very Good,” a higher rating than the X5’s headlights, which were rated “Fair.”

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The MDX’s headlights were rated “Good” by the IIHS, while the X5’s headlights are rated “Acceptable” to “Marginal.”

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Acura MDX has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the X5.

The MDX offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The X5 doesn’t offer a house-current electrical outlet.

Economic Advantages

Insurance will cost less for the MDX owner. The Complete Car Cost Guide estimates that insurance for the MDX will cost $3355 to $5225 less than the X5 over a five-year period.

The MDX will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the MDX will retain 50.63% to 53.63% of its original price after five years, while the X5 only retains 48.6% to 49.43%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura MDX will be $15239 to $16264 less than for the BMW X5.

Recommendations

Consumer Reports® recommends both the Acura MDX and the BMW X5, based on reliability, safety and performance.
