For enhanced safety, the front and rear seat shoulder belts of the Mercedes A-Class 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 Acura TLX doesn’t offer pretensioners for the rear seat belts.

The A-Class’ 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 TLX doesn’t offer a driver alert monitor.

Both the A-Class and the TLX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front-wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all-wheel drive, lane departure warning systems, blind spot warning systems and around view monitors.

The A-Class offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The TLX’s suspension doesn’t offer adjustable shock absorbers.

The A-Class’ drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The TLX doesn’t offer drift compensation steering.

The A 220 4MATIC handles at .95 G’s, while the TLX V6 SH-AWD pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

The A 220 executes Motor Trend’s “Figure Eight” maneuver quicker than the TLX (26.5 seconds @ .68 average G’s vs. 27 seconds @ .74 average G’s).

For better maneuverability, the A-Class’ turning circle is 2.7 feet tighter than the TLX V6’s (36.1 feet vs. 38.8 feet). The A-Class’ turning circle is 3.4 feet tighter than the TLX SH-AWD’s (36.1 feet vs. 39.5 feet).

A low lift-over trunk design makes loading and unloading the A-Class easier. The A-Class’ trunk lift-over height is 26.1 inches, while the TLX’s liftover is 27.5 inches.

To make loading groceries and cargo easier when your hands are full, the A-Class’ available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The TLX doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Unlike the driver-only memory system in the TLX, the A-Class has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The A-Class offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The TLX doesn’t offer a heads-up display.

The power windows standard on both the A-Class and the TLX have locks to prevent small children from operating them. When the lock on the A-Class is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The TLX prevents the driver from operating the other windows just as it does the other passengers.

The A-Class’ rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The TLX’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To help drivers avoid possible obstacles, the A-Class offers optional cornering lights to illuminate around corners when the turn signals are activated. The TLX doesn’t offer cornering lights. The A-Class also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The A-Class’ optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The TLX doesn’t offer an automated parking system.
