Compare the2026 Mercedes AMG CLAVS 2025 Acura TLX

The AMG 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 AMG 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 AMG CLA offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The TLX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG CLA. But it costs extra on the TLX.

Both the AMG CLA and TLX have rear cross-traffic warning, but the AMG CLA has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The TLX’s Rear Cross Traffic Monitor doesn’t automatically brake.

Both the AMG 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available lane departure warning systems and around view monitors.

There are over 40 percent more Mercedes dealers than there are Acura dealers, which makes it easier should you ever need service under the AMG CLA’s warranty.

A hardened steel chain, with no maintenance needs, drives the camshafts in the AMG 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.

J.D. Power and Associates’ 2025 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Acura With 6 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Mercedes higher than Acura.

The AMG CLA 35’s standard 2.0 turbo 4-cylinder hybrid produces 30 more horsepower (302 vs. 272) and 15 lbs.-ft. more torque (295 vs. 280) than the TLX’s standard 2.0 turbo 4-cylinder. The AMG CLA 45 S’ standard 2.0 turbo 4-cylinder hybrid produces 61 more horsepower (416 vs. 355) and 15 lbs.-ft. more torque (369 vs. 354) than the TLX Type S’ standard 3.0 turbo V6.

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

			MPG

		2.0 turbo 4-cyl.	22 city/29 hwy
TLX
	AWD	2.0 turbo 4-cyl.	21 city/29 hwy
		3.0 turbo V6	19 city/25 hwy

Regenerative brakes improve the AMG CLA’s fuel efficiency by converting inertia back into energy instead of wasting it. The TLX doesn’t offer a regenerative braking system.

The AMG 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 AMG CLA’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The TLX doesn’t offer launch control.

For better stopping power the AMG CLA’s standard brake rotors are larger than those on the TLX:

	AMG CLA	TLX
Front Rotors	13.8 inches	13 inches

The AMG CLA’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the TLX are solid, not vented.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the AMG 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 AMG 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 AMG CLA 45 S handles at .99 G’s, while the TLX A-Spec SH-AWD pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The AMG CLA 45 S executes Motor Trend’s “Figure Eight” maneuver 2.8 seconds quicker than the TLX A-Spec SH-AWD (24.1 seconds @ .8 average G’s vs. 26.9 seconds @ .64 average G’s).

For better maneuverability, the AMG CLA’s turning circle is 2.1 feet tighter than the TLX’s (38.1 feet vs. 40.2 feet).

The AMG CLA is 9.8 inches shorter than the TLX, making the AMG CLA easier to handle, maneuver and park in tight spaces.

To make loading groceries and cargo easier when your hands are full, the AMG CLA’s 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 AMG 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 AMG CLA and the TLX have locks to prevent small children from operating them. When the lock on the AMG 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 AMG CLA’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. Smart Entry standard on the TLX doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The AMG 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 optional on the AMG 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 AMG CLA offers optional cornering lights to illuminate around corners when the turn signals are activated. The TLX doesn’t offer cornering lights. The AMG CLA also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The AMG CLA’s standard 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 Mercedes AMG CLA has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors are only offered on the TLX Type S.

The AMG CLA offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the TLX.

The AMG CLA’s 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 AMG CLA 45 S higher than the Acura TLX A-Spec SH-AWD.

The Mercedes CLA outsold the Acura TLX by 51% during 2024.
