Compare the2025 Acura MDXVS 2025 BMW X7

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 X7 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 X7 doesn’t offer height-adjustable front seat belts.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Acura MDX achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The BMW X7 has not been tested.

Both the MDX and the X7 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 achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2025 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated moderate overlap front crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The X7 has not yet been evaluated by the IIHS for 2025.

Acura’s powertrain warranty covers the MDX 2 years and 20,000 miles longer than BMW covers the X7. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X7 ends after only 4 years or 50,000 miles.

On the EPA test cycle the MDX gets better mileage than the X7:

An engine control system that can shut down some of the engine’s cylinders helps improve the MDX’s fuel efficiency. The X7 doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Acura MDX uses regular unleaded gasoline (premium recommended for maximum performance). The X7 requires premium, which can cost on average about 84.9 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 X7 doesn’t offer a cap-less fueling system.

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 X7.

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 X7 doesn’t offer vehicle monitored tire inflation.

For better handling and stability, the track (width between the wheels) on the MDX is 1.3 inches wider in the front and .9 inches wider in the rear than the average track on the X7.

The MDX Type S executes Motor Trend’s “Figure Eight” maneuver quicker than the X7 xDrive40i (25.7 seconds @ .72 average G’s vs. 26.1 seconds @ .7 average G’s).

For better maneuverability, the MDX’s turning circle is .2 feet tighter than the X7 w/Rear Steering’s (40.5 feet vs. 40.7 feet). The MDX’s turning circle is 2.2 feet tighter than the X7 xDrive40i’s (40.5 feet vs. 42.7 feet).

For greater off-road capability the MDX Type S has a greater minimum ground clearance than the X7 (9.4 vs. 8.7 inches), allowing the MDX to travel over rougher terrain without being stopped or damaged.

The Acura MDX may be more efficient, handle and accelerate better because it weighs about 1200 pounds less than the BMW X7.

The MDX is 5.2 inches shorter than the X7, making the MDX easier to handle, maneuver and park in tight spaces.

The MDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The X7 doesn’t offer active noise cancellation.

The MDX has 1.8 inches more front legroom, 1.9 inches more front shoulder room, .9 inches more rear legroom, 2.2 inches more rear shoulder room and 7 inches more third row shoulder room than the X7.

The MDX’s cargo area provides more volume than the X7.

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 X7’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.

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 9% lower rating, BMW is ranked 10th.

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 X7 only has an intermittent setting, so in a hard rain visibility isn’t as good.

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 X7 doesn’t offer a house-current electrical outlet.

The MDX is available in both front-wheel drive and four-wheel drive configurations. The X7 doesn’t offer a two-wheel drive configuration.

Insurance will cost less for the MDX owner. The Complete Car Cost Guide estimates that insurance for the MDX will cost $6960 to $12715 less than the X7 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 X7 only retains 46.74% to 50.28%.
