Compare the2023 Mercedes CLAVS 2022 Acura TLX

The CLA’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The TLX doesn’t offer pre-crash pretensioners.

The CLA’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The TLX doesn’t offer a whiplash protection system.

The CLA has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the TLX’s blind spot costs extra.

To help make backing out of a parking space safer, the CLA has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the TLX.

Both the CLA and the TLX 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, lane departure warning systems and around view monitors.

There are over 41 percent more Mercedes dealers than there are Acura dealers, which makes it easier should you ever need service under the CLA’s warranty.

A hardened steel chain, with no maintenance needs, drives the camshafts in the CLA’s engine. A rubber cam drive belt that needs periodic replacement drives the TLX’s camshafts. If the TLX’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

As tested in Motor Trend the Mercedes CLA is faster than the Acura TLX turbo 4 cyl.:

On the EPA test cycle the CLA gets better mileage than the TLX:

The CLA offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The TLX doesn’t offer an SMG or a conventional manual transmission.

The CLA stops much shorter than the TLX:

The CLA’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 TLX’s standard 50 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the CLA can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The TLX doesn’t offer run-flat tires.

The CLA’s 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 CLA 250 4MATIC handles at .86 G’s, while the TLX A-Spec SH-AWD pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The CLA 250 4MATIC executes Motor Trend’s “Figure Eight” maneuver quicker than the TLX A-Spec SH-AWD (26.5 seconds @ .67 average G’s vs. 26.9 seconds @ .64 average G’s).

For better maneuverability, the CLA’s turning circle is 4 feet tighter than the TLX’s (36.1 feet vs. 40.1 feet). The CLA’s turning circle is 4.1 feet tighter than the TLX Technology/A-Spec/Advance/Type S’ (36.1 feet vs. 40.2 feet).

The Mercedes CLA may be more efficient, handle and accelerate better because it weighs about 350 to 750 pounds less than the Acura TLX.

The CLA is 10 inches shorter than the TLX, making the CLA easier to handle, maneuver and park in tight spaces.

To make loading groceries and cargo easier when your hands are full, the CLA’s 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 seat and mirrors in the TLX, the CLA 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 power windows standard on both the CLA and the TLX have locks to prevent small children from operating them. When the lock on the CLA 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 CLA’s 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 standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are standard on the CLA to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The TLX doesn’t offer heated windshield washer nozzles.

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

The CLA’s optional 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 TLX has an automatic rear view mirror, but its side mirrors don’t dim.

The CLA’s 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.

Motor Trend performed a comparison test in its January 2021 issue and they ranked the Mercedes CLA 250 4MATIC higher than the Acura TLX A-Spec SH-AWD.
