In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the XT4 are reminded to check the back seat if they opened the rear door before starting out. The 500X doesn’t offer a back seat reminder.

The Cadillac XT4 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 500X doesn’t offer a front passenger side knee airbag.

Over 200 people are killed each year when backed over by motor vehicles. The XT4 Premium Luxury/Sport offers optional Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 500X doesn’t offer backup collision prevention brakes.

The XT4’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 500X and is only available on 500X Sport.

The XT4 Premium Luxury/Sport offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The 500X only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The XT4 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 and moves the vehicle back into its lane. A system to reveal vehicles in the 500X’s blind spot costs extra.

To help make backing out of a parking space safer, the XT4 has standard Rear Cross Traffic Alert and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. Fiat charges extra for Rear Cross Path Detection on the 500X, and only on the Sport and the 500X’s Rear Cross Path Detection does not include automatic braking.

Both the XT4 and the 500X have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras and available all wheel drive.

Warranty

Cadillac’s powertrain warranty covers the XT4 2 years and 20,000 miles longer than Fiat covers the 500X. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 500X ends after only 4 years or 50,000 miles.

The XT4’s corrosion warranty is 1 year longer than the 500X’s (6 vs. 5 years).

There are over 56 percent more Cadillac dealers than there are Fiat dealers, which makes it much easier should you ever need service under the XT4’s warranty.

Reliability

J.D. Power and Associates rated the XT4 third among compact premium suvs in their 2023 Initial Quality Study. The 500X isn’t in the top three in its category.

Engine

The XT4’s 2.0 turbo 4-cylinder produces 58 more horsepower (235 vs. 177) and 48 lbs.-ft. more torque (258 vs. 210) than the 500X’s 1.3 turbo 4-cylinder.

Fuel Economy and Range

An engine control system that can shut down some of the engine’s cylinders helps improve the XT4’s fuel efficiency. The 500X doesn’t offer a system that can shut down part of the engine.

The XT4 FWD’s standard fuel tank has 3.2 gallons more fuel capacity than the 500X (15.9 vs. 12.7 gallons), for longer range between fill-ups. The XT4 AWD’s standard fuel tank has 3.6 gallons more fuel capacity than the 500X (16.3 vs. 12.7 gallons).

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Cadillac XT4 higher (7 out of 10) than the Fiat 500X (6). This means the XT4 produces up to 1.1 pounds less smog-producing pollutants than the 500X every 15,000 miles.

Brakes and Stopping

For better stopping power the XT4’s brake rotors are larger than those on the 500X:

	XT4	500X
Front Rotors	12.6 inches	12 inches
Rear Rotors	12.4 inches	10.95 inches

The XT4’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the 500X are solid, not vented.

The XT4 stops shorter than the 500X:

	XT4	500X
60 to 0 MPH	118 feet	123 feet	Motor Trend
60 to 0 MPH (Wet)	141 feet	146 feet	Consumer Reports

Tires and Wheels

For better traction, the XT4 has larger standard tires than the 500X (235/60R18 vs. 215/60R17). The XT4’s optional tires are larger than the largest tires available on the 500X (245/45R20 vs. 225/55R18).

For better ride, handling and brake cooling the XT4 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the 500X AWD. The XT4’s optional 20-inch wheels are larger than the 19-inch wheels optional on the 500X Sport.

The XT4 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 500X doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The XT4 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 or off-road. The 500X’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the XT4’s wheelbase is 8.2 inches longer than on the 500X (109.4 inches vs. 101.2 inches).

For better handling and stability, the track (width between the wheels) on the XT4 is 2.5 inches wider in the front and 2.4 inches wider in the rear than on the 500X.

The XT4’s front to rear weight distribution is more even (58.4% to 41.6%) than the 500X’s (60.3% to 39.7%). This gives the XT4 more stable handling and braking.

The XT4 Sport AWD handles at .89 G’s, while the 500X pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

The XT4 Sport AWD executes Motor Trend’s “Figure Eight” maneuver 2.4 seconds quicker than the 500X (26.3 seconds @ .66 average G’s vs. 28.7 seconds @ .59 average G’s).

Chassis

The front grille of the XT4 Premium Luxury/Sport uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The 500X doesn’t offer active grille shutters.

The XT4 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 500X doesn’t offer active noise cancellation.

Passenger Space

The XT4 has 9.6 cubic feet more passenger volume than the 500X (101.3 vs. 91.7).

The XT4 has .3 inches more front headroom, 2.7 inches more front legroom, 1.2 inches more front hip room, 2.7 inches more front shoulder room, .5 inches more rear headroom, 4.7 inches more rear legroom and 2.3 inches more rear shoulder room than the 500X.

The front step up height for the XT4 is 2.4 inches lower than the 500X (17” vs. 19.4”). The XT4’s rear step up height is 2.1 inches lower than the 500X’s (17.5” vs. 19.6”).

Cargo Capacity

The XT4 has a much larger cargo volume with its rear seat up than the 500X with its rear seat up (22.5 vs. 14.1 cubic feet). The XT4 has a much larger cargo volume with its rear seat folded than the 500X with its rear seat folded (48.9 vs. 39.8 cubic feet).

The XT4’s cargo area is larger than the 500X’s in almost every dimension:

	XT4	500X
Length to seat (2nd/1st)	37.5”/67.4”	n/a
Max Width	50”	41.3”
Min Width	38.7”	37.8”
Height	26.6”	28.8”

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the XT4. The 500X doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier, especially for short adults, the XT4 has a standard power liftgate, which opens and closes automatically by pressing a button, or on the XT4 Premium Luxury/Sport, by just kicking your foot under the back bumper, completely leaving your hands free. The 500X doesn’t offer a power liftgate.

Towing

Maximum trailer towing in the Fiat 500X is limited to 2000 pounds. The XT4 offers up to a 3500 lbs. towing capacity.

Standard Trailer Sway Control on the XT4 uses the StabiliTrak® sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The 500X doesn’t offer electronic trailer sway control.

Servicing Ease

The XT4 uses gas struts to support the hood for easier service access. The 500X uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

Ergonomics

When two different drivers share the XT4 Premium Luxury/Sport, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position (with optional power wheel adjuster) and outside mirror angle. The 500X doesn’t offer a memory system.

The XT4 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 500X doesn’t offer an easy entry system.

The XT4’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 500X does not have an oil pressure gauge.

The XT4 Premium Luxury/Sport 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 500X doesn’t offer a heads-up display.

On a hot day the XT4’s driver can lower all the windows from a distance using the keyless remote. The driver of the 500X can only operate the windows from inside the vehicle, with the ignition on.

The XT4 has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The 500X only offers an automatic headlight on/off feature as an extra cost option.

When the XT4 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 500X’s mirrors don’t automatically adjust for backing.

The XT4 Premium Luxury/Sport’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 500X has an automatic rear view mirror, but its side mirrors don’t dim.

Both the XT4 and the 500X offer available heated front seats. The XT4 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the 500X.

Optional air-conditioned seats in the XT4 Premium Luxury/Sport keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The 500X doesn’t offer air-conditioned seats.

On extremely cold winter days, the XT4’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The 500X doesn’t offer a heated steering wheel.

The XT4 has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable and it can provide a boundary between children. The 500X doesn’t offer a rear seat center armrest.

The XT4 Premium Luxury/Sport offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the 500X.

The XT4 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 500X Sport.

For greater rear passenger comfort, the XT4 has standard rear a/c vents to keep rear occupants more comfortable. The 500X doesn’t offer rear vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Cadillac XT4 Premium Luxury/Sport offers an optional wireless phone charging system (Qi) in the center console. The 500X doesn’t offer wireless personal charging.

The XT4 Premium Luxury/Sport’s optional Automatic Park Assist can parallel park by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The 500X doesn’t offer an automated parking system.

Model Availability

The XT4 is available in both front-wheel drive and four-wheel drive configurations. The 500X doesn’t offer a two-wheel drive configuration.

Economic Advantages

According to The Car Book by Jack Gillis, the XT4 is less expensive to operate than the 500X because typical repairs cost much less on the XT4 than the 500X, including $215 less for a fuel pump.

Recommendations

The Cadillac XT4 outsold the Fiat 500X by almost 25 to one during 2022.
