Safety

Over 200 people are killed each year when backed over by motor vehicles. The UX Series offers optional Parking Support Brake which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The 500X doesn’t offer backup collision prevention brakes.

The UX Series offers optional Parking Support Alert to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The 500X doesn’t offer a front parking aid.

Both the UX Series and the 500X have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.

Warranty

Lexus’ powertrain warranty covers the UX Series 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 UX Series’ corrosion warranty is 1 year longer than the 500X’s (6 vs. 5 years).

Reliability

The camshafts in the UX Series’ engine are driven by a hardened steel chain, with no maintenance needs. The 500X Pop’s camshafts are driven by a rubber belt that needs periodic replacement. If the 500X’s cam drive belt breaks the engine could be severely damaged when the pistons hit the opened valves.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Fiat vehicles. J.D. Power ranks Lexus first in reliability, above the industry average. With 93 more problems per 100 vehicles, Fiat is ranked 29th.

Engine

The UX 200’s standard 2.0 DOHC 4 cyl. produces 9 more horsepower (169 vs. 160) than the 500X Pop’s standard 1.4 turbo 4 cyl.

Regenerative brakes improve the UX Series Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The 500X doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Lexus UX Series uses regular unleaded gasoline. The 500X Pop requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

Transmission

The Lexus UX Series comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the 500X.

The UX Series has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The 500X doesn’t offer a CVT.

Tires and Wheels

For better traction, the UX Series has larger tires than the 500X (225/50R18 vs. 215/60R16).

The UX Series’ tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the 500X Pop’s standard 60 series tires.

For better ride, handling and brake cooling the UX Series has standard 18-inch wheels. Smaller 16-inch wheels are standard on the 500X Pop.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the UX Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The 500X doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the UX Series’ wheelbase is 2.7 inches longer than on the 500X (103.9 inches vs. 101.2 inches).

For better maneuverability, the UX Series’ turning circle is 2.1 feet tighter than the 500X’s (34.2 feet vs. 36.3 feet).

Chassis

The design of the Lexus UX Series amounts to more than styling. The UX Series has an aerodynamic coefficient of drag of .33 Cd. That is lower than the 500X (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the UX Series get better fuel mileage.

Passenger Space

The UX Series has .7 inches more front legroom, .5 inches more front hip room, .8 inches more front shoulder room, .1 inches more rear hip room and .1 inches more rear shoulder room than the 500X.

Cargo Capacity

The UX Series has a much larger cargo area than the 500X with its rear seat up (21.7 vs. 12.2 cubic feet).

To make loading groceries and cargo easier when your hands are full, the UX Series’ available liftgate can be opened just by a gesture, leaving your hands completely free. The 500X doesn’t offer a hands-free gesture to open its cargo door, forcing you to put cargo down if your hands are full.

Servicing Ease

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

Ergonomics

The UX Series’ optional easy entry system raises the steering wheel 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 UX Series offers an optional heads-up display that projects speed 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.

The UX Series 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 has an automatic headlight on/off feature standard only on the Trekking/Lounge.

Optional air-conditioned seats in the UX Series 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.

To keep a safe, consistent following distance, the UX Series has a standard Dynamic Radar Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The 500X doesn’t offer an adaptive cruise control.
