Both the CT4 and WRX have child safety locks to prevent children from opening the rear doors. The CT4 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The WRX’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Cadillac CT4 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 CT4’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the WRX.

The CT4 Premium Luxury/Sport offers an optional HD Surround Vision 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 CT4 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 CT4 has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Only the WRX Limited/GT offers rear cross-path warning.

Both the CT4 and the WRX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available all wheel drive.

Warranty

The CT4 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car. The WRX’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Cadillac’s powertrain warranty covers the CT4 1 year and 10,000 miles longer than Subaru covers the WRX. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the WRX ends after only 5 years or 60,000 miles.

The CT4’s corrosion warranty is 1 year longer than the WRX’s (6 vs. 5 years).

Reliability

The battery on the CT4 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the CT4’s battery 20 to 30 degrees cooler, its life is increased by years. The WRX’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Cadillac vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Cadillac above average in initial quality. With 28 more problems per 100 vehicles, Subaru is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than Subaru vehicles. J.D. Power ranks Cadillac above average in long-term dependability. With 24 more problems per 100 vehicles in the first three years of ownership, Subaru is rated below average.

Engine

The CT4’s optional 2.7 turbo 4-cylinder produces 39 more horsepower (310 vs. 271) and 92 lbs.-ft. more torque (350 vs. 258) than the WRX’s 2.4 turbo 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the CT4 gets better mileage than the WRX:

			MPG
CT4
RWD	Auto	2.0 turbo 4-cyl.	23 city/34 hwy
		2.7 turbo 4-cyl.	21 city/31 hwy
AWD	Auto	2.0 turbo 4-cyl.	22 city/31 hwy
		2.7 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

An engine control system that can shut down some of the engine’s cylinders helps improve the CT4’s fuel efficiency. The WRX doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the CT4’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.

The CT4 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The WRX doesn’t offer a cap-less fueling system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac CT4 higher (6 to 7 out of 10) than the Subaru WRX (3). This means the CT4 produces up to 24.5 pounds less smog-producing pollutants than the WRX every 15,000 miles.

Transmission

The Cadillac CT4 comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the WRX.

Brakes and Stopping

For better stopping power the CT4 Sport’s brake rotors are larger than those on the WRX:

	CT4 Sport	WRX
Front Rotors	12.6 inches	12.4 inches
Rear Rotors	12.4 inches	11.4 inches
Opt Rear Rotors		11.8 inches

Tires and Wheels

The CT4’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the WRX’s optional 40 series tires.

For better ride, handling and brake cooling the CT4 offers optional 19-inch wheels. The WRX’s largest wheels are only 18-inches.

The CT4 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The WRX doesn’t offer vehicle monitored tire inflation.

Having a flat tire is dangerous, inconvenient and expensive. The self-sealing tires available on the CT4 can automatically seal most punctures up to 3/16 of an inch, effectively preventing most flat tires. The WRX doesn’t offer self-sealing tires.

Suspension and Handling

For a smoother ride and more stable handling, the CT4’s wheelbase is 4.2 inches longer than on the WRX (109.3 inches vs. 105.1 inches).

The CT4’s front to rear weight distribution is more even (54% to 46%) than the WRX’s (59.9% to 40.1%). This gives the CT4 more stable handling and braking.

Chassis

The front grille of the CT4 Premium Luxury uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The WRX doesn’t offer active grille shutters.

Towing

The CT4 has a 1000 lbs. towing capacity. The WRX has no towing capacity.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Subaru. J.D. Power ranks Cadillac second in service department satisfaction. With a 28% lower rating, Subaru is ranked 16th.

Ergonomics

When two different drivers share the CT4 Premium Luxury/Sport, the memory seats and mirrors make it convenient for both. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The WRX doesn’t offer a memory system.

The CT4 Premium Luxury/Sport’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The WRX doesn’t offer an easy entry system.

The CT4 Premium Luxury/Sport offers an optional heads-up display that projects speed, tachometer, warning 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 CT4’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 CT4 and the WRX have locks to prevent small children from operating them. When the lock on the CT4 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 CT4’s front and rear power windows all lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The WRX’s standard power windows’ rear power window switches have to be held the entire time to open them fully.

On a hot day the CT4’s driver can lower all the windows from a distance using the keyless remote. The driver of the WRX can only operate the windows from inside the vehicle, with the ignition on.

The CT4 Premium Luxury/Sport’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The WRX’s manually variable intermittent wipers have to be constantly adjusted.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the CT4 has standard extendable sun visors. The WRX doesn’t offer extendable visors.

The CT4’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 CT4 Premium Luxury/Sport is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The WRX’s mirrors don’t automatically adjust for backing.

Optional air-conditioned seats in the CT4 Premium Luxury/Sport 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.

On extremely cold winter days, the CT4’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The WRX doesn’t offer a heated steering wheel.

The CT4 Sport 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 CT4 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 CT4 and the WRX offer rear vents. For greater rear passenger comfort, the CT4 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 Cadillac CT4 has a standard wireless phone charging system (Qi) in the center console. The WRX doesn’t offer wireless personal charging.

Model Availability

The CT4 is available in both rear-wheel drive and all-wheel drive configurations. The WRX doesn’t offer a two-wheel drive configuration.
