For enhanced safety, the front and rear seat shoulder belts of the Volkswagen GTI 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 Cadillac CT4 doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Volkswagen GTI are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Cadillac CT4 doesn’t offer height-adjustable seat belts.

The GTI has a standard Automatic Post-Collision Braking System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The CT4 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.

Both the GTI and CT4 have rear cross-traffic warning, but the GTI has Rear Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The CT4’s Rear Cross Traffic Alert doesn’t automatically brake.

The GTI’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 CT4 doesn’t offer a driver alert monitor.

Both the GTI and the CT4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.

Warranty

The GTI’s corrosion warranty is 1 year longer than the CT4’s (7 vs. 6 years).

Volkswagen pays for scheduled maintenance on the GTI for 2 years and 20,000 miles. Volkswagen will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Cadillac only pays for the first scheduled maintenance visit on the CT4.

There are over 11 percent more Volkswagen dealers than there are Cadillac dealers, which makes it easier should you ever need service under the GTI’s warranty.

Reliability

The Volkswagen GTI’s engine uses a cast iron block for durability, while the CT4’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

From surveys of all its subscribers, Consumer Reports’ March 2025 Auto Issue reports that Volkswagen vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Volkswagen 3 places higher in reliability than Cadillac.

Engine

The GTI’s 2.0 turbo 4-cylinder produces 4 more horsepower (241 vs. 237) and 15 lbs.-ft. more torque (273 vs. 258) than the CT4’s standard 2.0 turbo 4-cylinder.

As tested in Car and Driver the Volkswagen GTI is faster than the Cadillac CT4 2.0 turbo 4-cylinder:

	GTI	CT4
Zero to 60 MPH	5.1 sec	5.8 sec
Zero to 100 MPH	12.2 sec	15.2 sec
5 to 60 MPH Rolling Start	5.5 sec	6.5 sec
Passing 30 to 50 MPH	2.7 sec	3.5 sec
Passing 50 to 70 MPH	3.8 sec	4.3 sec
Quarter Mile	13.6 sec	14.3 sec
Speed in 1/4 Mile	105 MPH	97 MPH
Top Speed	155 MPH	138 MPH

Fuel Economy and Range

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

			MPG
GTI
	FWD	2.0 turbo 4-cyl.	24 city/32 hwy
CT4
	RWD	2.0 turbo 4-cyl.	22 city/32 hwy
		2.7 turbo 4-cyl.	21 city/31 hwy
	AWD	2.0 turbo 4-cyl.	21 city/31 hwy
		2.7 turbo 4-cyl.	21 city/29 hwy

To lower fuel costs and make buying fuel easier, the Volkswagen GTI uses regular unleaded gasoline (premium recommended for maximum performance). The CT4 requires premium, which can cost on average about 84.9 cents more per gallon.

The GTI has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the CT4. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Transmission

The GTI 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 CT4 doesn’t offer an SMG or a conventional manual transmission.

The GTI Automatic’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 CT4 doesn’t offer launch control.

Brakes and Stopping

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

	GTI	CT4	CT4 Sport
Front Rotors	13.4 inches	11.8 inches	12.6 inches

The GTI stops much shorter than the CT4:

	GTI	CT4
100 to 0 MPH	304 feet	324 feet	Car and Driver
70 to 0 MPH	150 feet	158 feet	Car and Driver
60 to 0 MPH	104 feet	123 feet	Motor Trend

Tires and Wheels

The GTI’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 CT4 Luxury’s 45 series tires.

For better ride, handling and brake cooling the GTI has standard 18-inch wheels. Smaller 17-inch wheels are standard on the CT4 Luxury.

The GTI has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the CT4; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the CT4 don’t have a run-flat feature, either.

Suspension and Handling

The GTI offers an available 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 CT4’s suspension doesn’t offer adjustable shock absorbers.

The GTI Autobahn handles at .98 G’s, while the CT4 Premium Luxury pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

The GTI executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the CT4 Premium Luxury AWD (25 seconds @ .74 average G’s vs. 26.5 seconds @ .67 average G’s).

Chassis

The Volkswagen GTI may be more efficient, handle and accelerate better because it weighs about 250 to 550 pounds less than the Cadillac CT4.

The GTI is 1 foot, 6.3 inches shorter than the CT4, making the GTI easier to handle, maneuver and park in tight spaces.

Passenger Space

The GTI has .2 inches more front headroom, .4 inches more front hip room, .7 inches more front shoulder room, 1.6 inches more rear headroom and 1.6 inches more rear legroom than the CT4.

The front step up height for the GTI is 1.5 inches lower than the CT4 (15” vs. 16.5”). The GTI’s rear step up height is 2 inches lower than the CT4’s (15” vs. 17”).

Cargo Capacity

A low lift-over trunk design makes loading and unloading the GTI easier. The GTI’s trunk lift-over height is 26.5 inches, while the CT4’s liftover is 30 inches.

Ergonomics

The GTI’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The CT4 does not have an oil pressure gauge.

The GTI’s front and rear power windows all open or close 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 CT4’s rear power window switches have to be held the entire time to close them fully.

The GTI’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 CT4’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the GTI to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The CT4 doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the GTI has a standard rear wiper. The CT4 doesn’t offer a rear wiper.

The CT4 Premium Luxury/Sport’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The GTI’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

Both the Volkswagen GTI and Cadillac CT4 offer exterior mirrors that can be folded to provide convenience. The GTI features standard power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the CT4’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The GTI has standard heated front seats. Heated front seats cost extra on the CT4. The GTI Autobahn also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the CT4.

The GTI has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the CT4.

The GTI Autobahn’s Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The CT4 doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the GTI owner. The Complete Car Cost Guide estimates that insurance for the GTI will cost $930 to $3385 less than the CT4 over a five-year period.

Recommendations

The Volkswagen GTI outsold the Cadillac CT4 by 65% during 2024.
