Safety

For enhanced safety, the front shoulder belts of the Cadillac XT4 are height-adjustable, and the rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Fiat 500X has only front height-adjustable seat belts.

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.

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

The XT4 Premium/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.

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, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.

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).

Cadillac pays for the first scheduled maintenance on the XT4. Cadillac will pay for an oil change, lubrication and any other required maintenance. Fiat doesn’t pay scheduled maintenance for the 500X.

There are over 2 times as many Cadillac dealers as 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’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Cadillac vehicles are more reliable than Fiat vehicles. J.D. Power ranks Cadillac 27th in reliability. With 6 more problems per 100 vehicles, Fiat is ranked 29th.

Engine

The XT4’s 2.0 turbo 4 cyl. produces 60 more horsepower (237 vs. 177) and 48 lbs.-ft. more torque (258 vs. 210) than the 500X’s 1.3 turbo 4 cyl.

Fuel Economy and Range

An engine control system that can shut down half 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).

Brakes and Stopping

Tires and Wheels

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

The XT4 Premium/Sport’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the 500X AWD Trekking/Trekking Plus’ optional 55 series tires.

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 Premium/Sport’s optional 20-inch wheels are larger than the 18-inch wheels optional on the 500X AWD Trekking/Trekking Plus.

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 Trekking (26.3 seconds @ .66 average G’s vs. 28.7 seconds @ .59 average G’s).

Chassis

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 9.3 cubic feet more passenger volume than the 500X (101 vs. 91.7).

The XT4 has .3 inches more front headroom, 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.

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. 12.2 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. 32.1 cubic feet).

A standard locking glovebox 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 Premium/Sport has a standard power liftgate, which opens and closes automatically by pressing a button or, optionally on the XT4 Premium/Sport, by just kicking your foot under the back bumper, completely leaving your hands free. The 500X doesn’t offer a power liftgate.

Towing

The XT4’s standard towing capacity is much higher than the 500X’s (2500 vs. 0 pounds). Maximum trailer towing in the Fiat 500X is only 1000 pounds. The XT4 offers up to a 3500 lbs. towing capacity.

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.

J.D. Power and Associates surveys of service recipients show that Cadillac service is better than Fiat. J.D. Power ranks Cadillac third in service department satisfaction. With a 127% lower rating, Fiat is ranked 31st.

Ergonomics

When two different drivers share the XT4 Premium/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/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 Premium/Sport 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 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 Luxury’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The 500X’s standard manually variable intermittent wipers have to be constantly adjusted.

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/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/Sport has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The 500X offers 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/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. The 500X doesn’t offer a rear seat center armrest.

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 costs extra on the 500X and isn’t available on the 500X Pop.

The XT4’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The 500X Pop doesn’t offer automatic air conditioning.

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/Sport offers an optional wireless phone charging system (Qi) in the center console. The 500X doesn’t offer wireless personal charging.

The XT4 Premium/Sport’s optional Automatic Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The 500X doesn’t offer an automated parking system.
