Regenerative brakes improve the X2’s fuel efficiency by converting inertia back into energy instead of wasting it. The RDX doesn’t offer a regenerative braking system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW X2 higher (7 out of 10) than the Acura RDX (6). This means the X2 produces up to 1.1 pounds less smog-producing pollutants than the RDX every 15,000 miles.

Transmission

The X2’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The RDX doesn’t offer launch control.

Brakes and Stopping

For better stopping power the X2’s front brake rotors are larger than those on the RDX:

The X2’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the RDX are solid, not vented.

The X2 stops much shorter than the RDX:

Tires and Wheels

The X2’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.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the X2 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The RDX doesn’t offer run-flat tires.

Suspension and Handling

The X2 xDrive28i handles at .91 G’s, while the RDX A-Spec AWD pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

The X2 sDrive28i xDrive executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the RDX AWD (25.9 seconds @ .68 average G’s vs. 27.7 seconds @ .62 average G’s).

For better maneuverability, the X2’s turning circle is 1.7 feet tighter than the RDX’s (37.2 feet vs. 38.9 feet).

Chassis

The BMW X2 may be more efficient, handle and accelerate better because it weighs about 300 to 350 pounds less than the Acura RDX.

The X2 is 1 foot, 2.6 inches shorter than the RDX, making the X2 easier to handle, maneuver and park in tight spaces.

Passenger Space

For enhanced passenger comfort on long trips the X2’s rear seats recline. The RDX’s rear seats don’t recline.

Payload

The X2 has a higher standard payload capacity than the RDX (899 vs. 838 lbs.).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that BMW service is better than Acura. J.D. Power ranks BMW 8th in service department satisfaction (above the industry average). With a 12% lower rating, Acura is ranked 12th.

Ergonomics

The X2’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The RDX’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To help drivers avoid possible obstacles, the X2 has standard cornering lights to illuminate around corners when the turn signals are activated. The RDX doesn’t offer cornering lights.

The X2’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The RDX doesn’t offer an automated parking system.

Recommendations

Consumer Reports® recommends the BMW X2, based on reliability, safety and performance.
