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.
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.

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. The X2 M35i’s optional tires have a lower 40 series profile than the RDX A-Spec’s 45 series tires.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard 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 .83 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 250 to 300 pounds less than the Acura RDX.
The X2 is 1 foot, 3.2 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 (941 vs. 838 lbs.).
The X2 has a higher maximum payload capacity than the RDX (970 vs. 838 lbs.).
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.
Consumer Reports rated the X2’s headlight performance “Very Good,” a higher rating than the RDX’s headlights, which were rated “Good.”
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 by itself, with the driver only controlling speed with the brake pedal. The RDX doesn’t offer an automated parking system.
