The RDX’s 2.0 turbo 4-cylinder produces 91 more horsepower (272 vs. 181) and 99 lbs.-ft. more torque (280 vs. 181) than the Outlander’s 2.5 DOHC 4-cylinder.

As tested in Consumer Reports the Acura RDX is faster than the Mitsubishi Outlander:

In heavy traffic or at stoplights the RDX’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Outlander doesn’t offer an automatic engine start/stop system.

The RDX has 2.6 gallons more fuel capacity than the Outlander (17.1 vs. 14.5 gallons), for longer range between fill-ups.

The RDX stops shorter than the Outlander:

The RDX’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Outlander ES’ standard 60 series tires.

For better ride, handling and brake cooling the RDX has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Outlander ES.

The RDX AWD has a standard space-saver spare (not available on FWD/A-Spec) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Outlander; it requires you to depend on roadside assistance and your vehicle will have to be towed.

The RDX offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Outlander’s suspension doesn’t offer adjustable shock absorbers.

The RDX has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Outlander doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the RDX’s wheelbase is 1.8 inches longer than on the Outlander (108.3 inches vs. 106.5 inches).

For better handling and stability, the track (width between the wheels) on the RDX is 1.5 inches wider in the front and 1.6 inches wider in the rear than on the Outlander.

For excellent aerodynamics, the RDX has standard flush composite headlights. The Outlander has recessed headlights that spoil its aerodynamic shape and create extra drag.

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

The RDX has 1 inch more front hip room, 1.8 inches more front shoulder room and .7 inches more rear shoulder room than the Outlander.

The RDX has a much larger cargo volume than the Outlander with its rear seat up (31.1 vs. 11.7 cubic feet).

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the RDX. The Outlander doesn’t offer locking storage for small valuables.

The RDX uses gas struts to support the hood for easier service access. The Outlander uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Acura service is better than Mitsubishi. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 17% lower rating, Mitsubishi is ranked 12th.

The power windows standard on both the RDX and the Outlander have locks to prevent small children from operating them. When the lock on the RDX is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Outlander prevents the driver from operating the other windows just as it does the other passengers.

The RDX’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Outlander’s standard passenger windows don’t open or close automatically.

If the windows are left open on the RDX the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Outlander can only operate the windows from inside the vehicle, with the ignition on.

The RDX’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Outlander’s power window, power lock and power mirror switches are unlit, making them difficult to find at night and operate safely.

The RDX’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mitsubishi only offers heated mirrors on the Outlander SE/SEL.

The RDX’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Outlander offers an automatic rear view mirror, but its side mirrors don’t dim.

Standard air-conditioned seats in the RDX A-Spec/Advance keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Outlander doesn’t offer air-conditioned seats.

Insurance will cost less for the RDX owner. The Complete Car Cost Guide estimates that insurance for the RDX will cost $2405 to $7210 less than the Outlander over a five-year period.
