For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG CLA 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.
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.
The AMG CLA’s 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 AMG CLA and the TLX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
There are over 42 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 ranks Mercedes 13th in reliability, above the industry average. With 37 more problems per 100 vehicles, Acura is ranked 26th.
From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Mercedes vehicles are more reliable than Acura vehicles. Consumer Reports ranks Mercedes 7 places higher in reliability than Acura.
The AMG CLA 35’s standard 2.0 turbo 4-cylinder produces 96 more horsepower (302 vs. 206) and 113 lbs.-ft. more torque (295 vs. 182) than the TLX’s standard 2.4 DOHC 4-cylinder. The AMG CLA 35’s 2.0 turbo 4-cylinder produces 12 more horsepower (302 vs. 290) and 28 lbs.-ft. more torque (295 vs. 267) than the TLX’s optional 3.5 SOHC V6. The AMG CLA 45’s standard 2.0 turbo 4-cylinder produces 92 more horsepower (382 vs. 290) and 87 lbs.-ft. more torque (354 vs. 267) than the TLX’s optional 3.5 SOHC V6.
On the EPA test cycle the AMG CLA 35 gets better fuel mileage than the TLX SH-AWD V6 (23 city/29 hwy vs. 20 city/29 hwy).
Regardless of its engine, the AMG CLA’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Acura only offers an automatic engine start/stop system on the TLX SH-AWD.
In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG CLA higher (5 out of 10) than the Acura TLX (3). This means the AMG CLA produces up to 16.5 pounds less smog-producing pollutants than the TLX every 15,000 miles.
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 brake rotors are larger than those on the TLX:
AMG CLA 45 opt.
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.
For better traction, the AMG CLA has larger tires than the TLX (235/35R19 vs. 225/55R17).
The AMG CLA 35’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the TLX’s standard 55 series tires. The AMG CLA’s optional tires have a lower 35 series profile than the TLX A-Spec’s 40 series tires.
For better ride, handling and brake cooling the AMG CLA 35 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the TLX.
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 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 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 is 5.9 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, just kicking your foot under the back bumper can open the AMG CLA’s available trunk, 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.
J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Acura. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 4% lower rating, Acura is ranked 6th.
Unlike the driver-only memory system 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 AMG CLA 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 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 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.
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 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 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.
