Safety Comparison

Both the MDX and the XT5 have standard driver and passenger frontal airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the MDX its highest rating: “Top Pick Plus” for 2017, a rating granted to only 54 vehicles tested by the IIHS. The XT5 is only a standard “Top Pick” for 2017.

Reliability Comparison

The engines in the MDX have a single overhead cam for simplicity. The engine in the XT5 has dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.

J.D. Power ranks Acura 8th in reliability, above the industry average. With 16 more problems per 100 vehicles, Cadillac is ranked 15th.

From surveys of all its subscribers, Consumer Reports’ April 2017 Auto Issue reports that Acura vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Acura 9 places higher in reliability than Cadillac.

Tires and Wheels Comparison

For better traction, the MDX has larger tires than the XT5 (245/60R18 vs. 235/65R18).

The MDX’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the XT5’s standard 65 series tires. The MDX’s optional tires have a lower 50 series profile than the XT5’s optional 55 series tires.

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 XT5 doesn’t offer vehicle monitored tire inflation.

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the MDX is 1.9 inches wider in the front and 1.9 inches wider in the rear than on the XT5.

The MDX SH-AWD handles at .83 G’s, while the XT5 pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

Chassis Comparison

The MDX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The XT5 doesn’t offer active noise cancellation.

As tested by Car and Driver, the interior of the MDX SH-AWD is quieter than the XT5 4x4:

Ergonomics Comparison

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. An easy entry system costs extra on the XT5.

The MDX’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The XT5’s rear power window switches have to be held the entire time to close them fully.

If the windows are left down on the MDX the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the XT5 can only raise the windows from inside the vehicle, with the ignition on.

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 XT5’s standard manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The MDX’s headlights were rated “Acceptable” by the IIHS, while the XT5’s headlights are rated “Marginal” to “Poor.”

The MDX offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The XT5 doesn’t offer a house-current electrical outlet.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the MDX is less expensive to operate than the XT5 because it costs $315 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the MDX than the XT5, including $278 less for an alternator, $40 less for front brake pads, $235 less for fuel injection and $356 less for a timing belt/chain.
