The Outlander’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The RDX doesn’t offer a driver alert monitor.

Both the Outlander and the RDX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive, lane departure warning systems and around view monitors.

Warranty

The Outlander comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The RDX’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Mitsubishi’s powertrain warranty covers the Outlander 4 years and 30,000 miles longer than Acura covers the RDX. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the RDX ends after only 6 years or 70,000 miles.

The Outlander’s corrosion warranty is 2 years longer than the RDX’s (7 vs. 5 years).

Mitsubishi pays for scheduled maintenance (up to 3 visits) on the Outlander for 1 year and 18000 miles longer than Acura pays for maintenance for the RDX (2/30,000 vs. 1/12000).

There are over 15 percent more Mitsubishi dealers than there are Acura dealers, which makes it easier should you ever need service under the Outlander’s warranty.

Reliability

The RDX’s redline is at 7000 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The Outlander has a 6000 RPM redline.

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

To lower fuel costs and make buying fuel easier, the Mitsubishi Outlander uses regular unleaded gasoline. The RDX requires premium for maximum efficiency, which can cost on average about 84.9 cents more per gallon.

Transmission

The Outlander has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The RDX doesn’t offer a CVT.

Brakes and Stopping

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

13.8 inches

12.4 inches

Rear Rotors

13 inches

12.2 inches

The Outlander’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.

Suspension and Handling

For better maneuverability, the Outlander’s turning circle is 2.2 feet tighter than the RDX’s (36.7 feet vs. 38.9 feet).

For greater off-road capability the Outlander ES/Trail has a greater minimum ground clearance than the RDX (8.3 vs. 8.2 inches), allowing the Outlander to travel over rougher terrain without being stopped or damaged. The Outlander SE/SEL’s minimum ground clearance is .2 inch higher than on the RDX (8.4 vs. 8.2 inches).

Chassis

The Mitsubishi Outlander may be more efficient, handle and accelerate better because it weighs about 50 to 250 pounds less than the Acura RDX.

The front grille of the Outlander uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The RDX doesn’t offer active grille shutters.

Passenger Space

The Outlander has standard seating for 7 passengers; the RDX can only carry 5.

The Outlander has 21.5 cubic feet more passenger volume than the RDX (125.5 vs. 104).

The Outlander has 1 inch more front headroom, .1 inches more front legroom, .8 inches more rear headroom, 1.5 inches more rear legroom and 3.4 inches more rear hip room than the RDX.

For enhanced passenger comfort on long trips the Outlander’s middle and third row seats recline. The RDX’s rear seats don’t recline.

Towing

The Outlander’s standard towing capacity is much higher than the RDX’s (2000 vs. 1500 pounds).

Standard Trailer Stability Assist on the Outlander uses the Active Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The RDX doesn’t offer electronic trailer sway control.

Ergonomics

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Outlander S-AWC has standard headlight washers to keep headlight output high. The RDX doesn’t offer headlight washers.

Manual rear side window sunshades are available in the Outlander to help block heat and glare for the rear passengers. The RDX doesn’t offer rear side window sunshades.

Model Availability

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