Compare the2023 Acura TLXVS 2022 Mercedes A-Class

For enhanced safety, the front seat shoulder belts of the Acura TLX are height-adjustable to accommodate a wide variety of driver and passenger heights.

The TLX’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the A-Class.

To help make backing out of a parking space safer, the TLX’s optional rear cross-path warning system uses sensors 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 TLX and the A-Class have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear 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, driver alert monitors, available all wheel drive, blind spot warning systems and around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the TLX its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 112 vehicles tested by the IIHS. The A-Class has not been tested, yet.

Acura’s powertrain warranty covers the TLX 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.

Acura pays for scheduled maintenance on the TLX for 2 years and 24,000 miles. Acura will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the A-Class.

The battery on the TLX is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the TLX’s battery 20 to 30 degrees cooler, its life is increased by years. The A-Class’ battery is in the hot engine compartment.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the TLX’s reliability 11 points higher than the A-Class.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Acura vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Acura 16 places higher in reliability than Mercedes.

The TLX’s standard 2.0 turbo 4-cylinder produces 84 more horsepower (272 vs. 188) and 59 lbs.-ft. more torque (280 vs. 221) than the A-Class’ 2.0 turbo 4-cylinder. The TLX Type S’ standard 3.0 turbo V6 produces 167 more horsepower (355 vs. 188) and 133 lbs.-ft. more torque (354 vs. 221) than the A-Class’ 2.0 turbo 4-cylinder.

The TLX has 2.4 gallons more fuel capacity than the A-Class (15.9 vs. 13.5 gallons), for longer range between fill-ups.

The TLX 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 A-Class doesn’t offer a cap-less fueling system.

A 10-speed automatic is standard on the Acura TLX, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A-Class.

For better stopping power the TLX’s brake rotors are larger than those on the A-Class:

The TLX stops much shorter than the A-Class:

For better traction, the TLX has larger standard tires than the A-Class (235/50R18 vs. 205/55R17). The TLX Type S’ tires are larger than the largest tires available on the A-Class (255/35R20 vs. 225/40R19).

The TLX’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the A-Class’ standard 55 series tires. The TLX Type S’ tires have a lower 35 series profile than the A-Class’ optional 40 series tires.

For better ride, handling and brake cooling the TLX has standard 18-inch wheels. Smaller 17-inch wheels are standard on the A-Class. The TLX Type S’ 20-inch wheels are larger than the 19-inch wheels optional on the A-Class.

The TLX 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 A-Class doesn’t offer vehicle monitored tire inflation.

For a smoother ride and more stable handling, the TLX’s wheelbase is 5.6 inches longer than on the A-Class (113 inches vs. 107.4 inches).

For better handling and stability, the track (width between the wheels) on the TLX is 2.3 inches wider in the front and 3.7 inches wider in the rear than on the A-Class.

The TLX Type S handles at .97 G’s, while the A 220 pulls only .87 G’s of cornering force in a Motor Trend skidpad test.

The TLX Type S executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the A 220 (25 seconds @ .75 average G’s vs. 26.5 seconds @ .68 average G’s).
