Safety Comparison

For enhanced safety, the front seat shoulder belts of the Acura RDX 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 X3 doesn’t offer height-adjustable seat belts.

Using vehicle speed sensors and seat sensors, smart airbags in the RDX deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The RDX’s side airbags will shut off if a child is leaning against the door. The X3’s side airbags don’t have smart features and will always deploy full force.

Both the RDX and the X3 have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, front seatbelt pretensioners, plastic fuel tanks, four wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all wheel drive.

Warranty Comparison

Acura’s powertrain warranty covers the RDX 2 years and 20,000 miles longer than BMW covers the X3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X3 ends after only 4 years or 50,000 miles.

Tires and Wheels Comparison

For better ride, handling and brake cooling the RDX has standard 18 inch wheels. Smaller 17 inch wheels are standard on the X3 xDrive28i.

The RDX has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the X3, 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.
