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 WRX doesn’t offer pre-crash pretensioners.

The Mercedes AMG CLA has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The WRX doesn’t offer a front passenger side knee airbag.

The AMG CLA offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The WRX only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

The AMG CLA has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the WRX Limited/GT offers a blind spot warning system.

To help make backing out of a parking space safer, the AMG CLA has standard Rear Cross-Traffic Alert and Active Brake Assist automatically engages the brakes to help avoid a collision. Only the WRX Limited/GT offers rear cross-path warning.

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 WRX doesn’t offer a driver alert monitor.

Both the AMG CLA and the WRX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available lane departure warning systems.

Warranty

The AMG CLA comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The WRX’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Reliability

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Subaru vehicles. With 2 fewer problems per 100 vehicles, JD Power ranks Mercedes higher than Subaru.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mercedes vehicles are more reliable than Subaru With 31 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Mercedes higher than Subaru.

Engine

The AMG CLA 35’s standard 2.0 turbo 4-cylinder produces 31 more horsepower (302 vs. 271) and 37 lbs.-ft. more torque (295 vs. 258) than the WRX’s 2.4 turbo 4-cylinder. The AMG CLA 45’s standard 2.0 turbo 4-cylinder produces 111 more horsepower (382 vs. 271) and 96 lbs.-ft. more torque (354 vs. 258) than the WRX’s 2.4 turbo 4-cylinder.

Fuel Economy and Range

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

			MPG
AMG CLA
AWD	Auto	2.0 turbo 4-cyl.	20 city/28 hwy
		2.0 turbo 4-cyl.	21 city/29 hwy
WRX
AWD	Manual	2.4 turbo flat-4	19 city/26 hwy
AWD	Auto	2.4 turbo flat-4	19 city/25 hwy

In heavy traffic or at stoplights the AMG CLA’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The WRX doesn’t offer an automatic engine start/stop system.

Transmission

The Mercedes AMG CLA comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the WRX.

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 more internally efficient than a CVT but just as easy to drive. The WRX doesn’t offer an SMG.

To facilitate fast shifting and allow the driver to focus on the road, the AMG CLA offers an optional up-shift light to indicate when the engine is approaching redline. The WRX doesn’t offer an up-shift light.

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 WRX doesn’t offer launch control.

Brakes and Stopping

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

	AMG CLA	AMG CLA 45	WRX
Front Rotors	13.8 inches	14.2 inches	12.4 inches
Rear Rotors	13 inches	13 inches	11.4 inches
Opt Rear Rotors			11.8 inches

The AMG CLA stops shorter than the WRX:

	AMG CLA	WRX
60 to 0 MPH	109 feet	112 feet	Motor Trend

Tires and Wheels

For better traction, the AMG CLA 45’s tires are larger than the largest tires available on the WRX (255/35R19 vs. 245/40R18).

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 WRX’s standard 45 series tires. The AMG CLA’s optional tires have a lower 35 series profile than the WRX’s optional 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 WRX. The AMG CLA’s optional 19-inch wheels are larger than the 18-inch wheels optional on the WRX.

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 WRX doesn’t offer run-flat tires.

Suspension and Handling

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 WRX doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the AMG CLA’s wheelbase is 2.3 inches longer than on the WRX (107.4 inches vs. 105.1 inches).

For better handling and stability, the average track (width between the wheels) on the AMG CLA is 2.1 inches wider in the front and 1.3 inches wider in the rear than the average track on the WRX.

The AMG CLA 45 handles at .99 G’s, while the WRX Limited pulls only .96 G’s of cornering force in a Motor Trend skidpad test.

The AMG CLA 45 executes Motor Trend’s “Figure Eight” maneuver quicker than the WRX Limited (24.1 seconds @ .8 average G’s vs. 24.8 seconds @ .75 average G’s).

Cargo Capacity

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

Ergonomics

When three different drivers share the AMG CLA, the memory seats and mirrors make it convenient for all three. Each setting activates different, customized memories for the driver and front passenger’s seat positions and outside mirror angle. The WRX doesn’t offer a memory system.

The AMG CLA’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The WRX doesn’t offer an easy entry system.

The AMG CLA offers an optional heads-up display that projects speed, tachometer and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The WRX doesn’t offer a heads-up display.

The AMG CLA’s power parking brake sets with one touch and releases with one touch or automatically. The WRX has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

The power windows standard on both the AMG CLA and the WRX 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 WRX prevents the driver from operating the rear windows just as it does the other passengers.

The AMG CLA’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The WRX’s standard rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the AMG CLA the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the WRX can only operate the windows from inside the vehicle, with the ignition on.

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 WRX’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard 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 WRX doesn’t offer heated windshield washer nozzles.

The AMG CLA’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Subaru only offers heated mirrors on the WRX Premium/Limited/GT.

When the AMG CLA is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The WRX’s mirror doesn’t automatically adjust for backing.

Optional air-conditioned seats in the AMG CLA keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The WRX doesn’t offer air-conditioned seats.

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 WRX.

The AMG CLA has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the WRX Premium/Limited/GT.

Both the AMG CLA and the WRX offer rear vents. For greater rear passenger comfort, the AMG CLA has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The WRX doesn’t offer rear air conditioning vents, only heat vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes AMG CLA offers an optional wireless phone charging system (Qi) in the center console. The WRX doesn’t offer wireless personal charging.

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 WRX doesn’t offer an automated parking system.
