Compare the2025 Acura MDXVS 2025 Toyota 4Runner

For enhanced safety, the front and second-row seat shoulder belts of the Acura MDX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Toyota 4Runner doesn’t offer pretensioners for its second-row seat belts.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Acura MDX achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Toyota 4Runner has not been tested.

For better protection of the passenger compartment, the MDX uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The 4Runner uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the MDX and the 4Runner have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.

The Acura MDX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2025 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated moderate overlap front crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The 4Runner has not yet been evaluated by the IIHS for 2025.

The MDX comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The 4Runner’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Acura’s powertrain warranty covers the MDX 1 year and 10,000 miles longer than Toyota covers the 4Runner. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 4Runner ends after only 5 years or 60,000 miles.

The MDX’s standard 3.5 SOHC V6 produces 12 more horsepower (290 vs. 278) than the 4Runner’s standard 2.4 turbo 4-cylinder. The MDX Type S’ standard 3.0 turbo V6 produces 29 more horsepower (355 vs. 326) than the 4Runner’s optional 2.4 turbo 4-cylinder hybrid.

As tested in Motor Trend the Acura MDX V6 is faster than the Toyota 4Runner turbo 4 cyl.:

	MDX	4Runner
Zero to 60 MPH	7.5 sec	7.8 sec
Quarter Mile	15.8 sec	15.9 sec

On the EPA test cycle the MDX 3.5 SOHC V6 FWD gets better fuel mileage than the 4Runner Limited RWD (19 city/26 hwy vs. 20 city/24 hwy).

An engine control system that can shut down some of the engine’s cylinders helps improve the MDX’s fuel efficiency. The 4Runner doesn’t offer a system that can shut down part of the engine.

Regardless of its engine, the MDX’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. Toyota only offers an automatic engine start/stop system on the 4Runner Limited/i-FORCE MAX.

The MDX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The 4Runner doesn’t offer a cap-less fueling system.

A 10-speed automatic is standard on the Acura MDX, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the 4Runner.

For better stopping power the MDX’s front brake rotors are larger than those on the 4Runner:

	MDX	MDX Type S	4Runner
Front Rotors	13.8 inches	14.3 inches	13.4 inches

The MDX stops shorter than the 4Runner:

	MDX	4Runner
60 to 0 MPH	122 feet	127 feet	Motor Trend

For better traction, the MDX Type S’ tires are larger than the largest tires available on the 4Runner (275/40R21 vs. 265/70R17).

The MDX’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 4Runner SR5’s standard 70 series tires. The MDX Type S’ tires have a lower 40 series profile than the 4Runner TRD Sport/Limited/Platinum’s 55 series tires.

For better ride, handling and brake cooling the MDX has standard 19-inch wheels. Smaller 17-inch wheels are standard on the 4Runner SR5. The MDX Type S’ 21-inch wheels are larger than the 20-inch wheels on the 4Runner TRD Sport/Limited/Platinum.

The MDX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The 4Runner doesn’t offer vehicle monitored tire inflation.

Having a flat tire is dangerous, inconvenient and expensive. The self-sealing tires available on the MDX can automatically seal most punctures up to 3/16 of an inch, effectively preventing most flat tires. The 4Runner doesn’t offer self-sealing tires.

The MDX Type S has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The MDX’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The 4Runner doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the MDX’s wheelbase is 1.6 inches longer than on the 4Runner (113.8 inches vs. 112.2 inches).

The MDX Type S handles at .87 G’s, while the 4Runner TRD Off-Road Premium pulls only .72 G’s of cornering force in a Motor Trend skidpad test.

The MDX Type S executes Motor Trend’s “Figure Eight” maneuver 2.3 seconds quicker than the 4Runner TRD Off-Road Premium (25.7 seconds @ .72 average G’s vs. 28 seconds @ .6 average G’s).

Unibody construction lowers the MDX’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The 4Runner doesn’t use unibody construction, but a body-on-frame design.

The MDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 4Runner doesn’t offer active noise cancellation.

The MDX has 4.1 inches more front hip room, 3.9 inches more front shoulder room, .3 inches more rear headroom, 3.7 inches more rear legroom, 1.7 inches more rear hip room and 2.5 inches more rear shoulder room than the 4Runner.

The MDX’s cargo area provides more volume than the 4Runner.

	MDX	4Runner
Behind Third Seat	18.1 cubic feet	12.1 cubic feet
Third Seat Folded	48.4 cubic feet	44.8 cubic feet
Second Seat Folded	95 cubic feet	84.4 cubic feet

J.D. Power and Associates surveys of service recipients show that Acura service is better than Toyota. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 27% lower rating, Toyota is ranked 24th.

The MDX offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 4Runner doesn’t offer a remote starting system.

Unlike the driver-only memory seat and mirrors in the 4Runner Premium/Limited/Trailhunter/TRD Pro/Platinum, the MDX offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The MDX’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The 4Runner doesn’t offer an easy entry system.

The MDX’s standard Keyless Access System allows you to unlock the doors from either front door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Smart Key standard on the 4Runner doesn’t offer a sensor on the cargo door The MDX’s optional Keyless Access System also allows you to unlock the doors from either rear door handle.

The MDX’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The 4Runner’s standard manually variable intermittent wipers have to be constantly adjusted.

To improve rear visibility by keeping the rear window clear, the MDX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the 4Runner only has an intermittent setting, so in a hard rain visibility isn’t as good.

Manual rear side window sunshades are available in the MDX to help block heat and glare for the rear passengers. The 4Runner doesn’t offer rear side window sunshades.

The MDX’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 4Runner offers an automatic rear view mirror, but its side mirrors don’t dim.

The MDX Advance has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the 4Runner.

The MDX has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the 4Runner Limited/Platinum/Trailhunter/TRD Pro.

The Acura MDX has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Homelink® is only available on the 4Runner Premium/Limited/Platinum/Trailhunter/TRD Pro.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Acura MDX has a standard wireless phone charging system (Qi) in the center console. Only the 4Runner TRD/Limited/Platinum/Trailhunter offers wireless charging.
