Using vehicle speed sensors, smart airbags in the ILX deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The ILX’s side airbags will shut off if a child is leaning against the door. The A-Class’ airbags don’t have smart features and will always deploy full force.

To help make backing safer, the ILX’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The A-Class doesn’t offer a cross-path warning system.

Both the ILX and the A-Class have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras and available blind spot warning systems.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the ILX the rating of “Top Pick” for 2017, a rating granted to only 154 vehicles tested by the IIHS. The A-Class has not been tested, yet.


Acura’s powertrain warranty covers the ILX 2 years and 20,000 miles longer than Mercedes covers the A-Class. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A-Class ends after only 4 years or 50,000 miles.


J.D. Power and Associates rated the ILX first among small premium cars in their 2018 Initial Quality Study. The A-Class isn’t in the top three in its category.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Acura vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Acura 4 places higher in reliability than Mercedes.


The ILX’s 2.4 DOHC 4 cyl. produces 13 more horsepower (201 vs. 188) than the A-Class’ 2.0 turbo 4 cyl.


An eight-speed automatic (SMG) is standard on the Acura ILX, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A-Class.

Tires and Wheels

For better traction, the ILX has larger standard tires than the A-Class (215/45R17 vs. 205/55R17). The ILX A-SPEC’s tires are larger than the largest tires available on the A-Class (225/40R18 vs. 205/55R17).

The ILX’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the A-Class’ standard 55 series tires. The ILX A-SPEC’s tires have a lower 40 series profile than the A-Class’ 55 series tires.


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

Passenger Space

The ILX has .5 inches more front legroom, .5 inches more front shoulder room and .1 inches more rear legroom than the A-Class.

Cargo Capacity

The ILX has a much larger trunk than the A-Class (12.4 vs. 8.6 cubic feet).
