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 Niro 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 Niro EX/SX has standard Parking Collision-Avoidance Assist 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.

When descending a steep, off-road slope, the Niro’s standard Downhill Brake Control allows you to creep down safely. The 500X doesn’t offer Downhill Brake Control.

The Niro’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 Niro 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 Niro has standard Rear Cross-Traffic Collision Warning and Rear Cross-Traffic Collision-Avoidance Assist 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 Niro 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 front and rear parking sensors.

Warranty

The Niro comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The 500X’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Kia’s powertrain warranty covers the Niro 6 years and 50,000 miles longer than Fiat covers the 500X. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the 500X ends after only 4 years or 50,000 miles.

There are over 2 times as many Kia dealers as there are Fiat dealers, which makes it much easier should you ever need service under the Niro’s warranty.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Niro’s reliability 45 points higher than the 500X.

Fuel Economy and Range

On the EPA test cycle the Niro gets better mileage than the 500X:

		MPG
Niro
	1.6 4-cyl. Hybrid	53 city/54 hwy
	Touring 1.6 4-cyl. Hybrid	53 city/45 hwy
500X
	1.3 turbo 4-cyl.	24 city/30 hwy

Regenerative brakes improve the Niro’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 Kia Niro uses regular unleaded gasoline. The 500X requires premium for maximum efficiency, which can cost on average about 82.8 cents more per gallon.

The Niro has a standard locking fuel door with a power remote release convenient to the driver. The fuel filler door is not lockable on the 500X. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Environmental Friendliness

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

Transmission

The Niro 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 500X doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

The Niro stops shorter than the 500X:

	Niro	500X
60 to 0 MPH	121 feet	123 feet	Motor Trend
60 to 0 MPH (Wet)	144 feet	146 feet	Consumer Reports

Suspension and Handling

For a smoother ride and more stable handling, the Niro’s wheelbase is 5.9 inches longer than on the 500X (107.1 inches vs. 101.2 inches).

For better handling and stability, the average track (width between the wheels) on the Niro is 1.4 inches wider in the front and 1.9 inches wider in the rear than the track on the 500X.

The Niro SX handles at .84 G’s, while the 500X pulls only .76 G’s of cornering force in a Motor Trend skidpad test.

The Niro SX executes Motor Trend’s “Figure Eight” maneuver quicker than the 500X (27.9 seconds @ .59 average G’s vs. 28.7 seconds @ .59 average G’s).

For better maneuverability, the Niro’s turning circle is 1.5 feet tighter than the 500X’s (34.8 feet vs. 36.3 feet).

Chassis

The Kia Niro may be more efficient, handle and accelerate better because it weighs about 50 to 250 pounds less than the Fiat 500X.

The design of the Kia Niro amounts to more than styling. The Niro has an aerodynamic coefficient of drag of .29 Cd. That is significantly lower than the 500X (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Niro get better fuel mileage.

The front grille of the Niro 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.

Passenger Space

The Niro has 13.4 cubic feet more passenger volume than the 500X (105.1 vs. 91.7).

The Niro has 1.4 inches more front headroom, .1 inches more front legroom, 2 inches more front shoulder room, 1.8 inches more rear headroom, 5 inches more rear legroom, .8 inches more rear hip room and 2.6 inches more rear shoulder room than the 500X.

Cargo Capacity

The Niro has a much larger cargo volume with its rear seat up than the 500X with its rear seat up (22.8 vs. 14.1 cubic feet). The Niro has a much larger cargo volume with its rear seat folded than the 500X with its rear seat folded (63.7 vs. 39.8 cubic feet).

To make loading and unloading groceries and cargo easier when your hands are full, the Niro SX’s power liftgate can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The Niro’s power liftgate can also be opened or closed by pressing a button. The 500X doesn’t offer a power or hands-free opening liftgate.

Servicing Ease

The Niro 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 Niro SX, 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 500X doesn’t offer a memory system.

The Niro SX’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.

On a hot day the Niro’s driver can lower the front 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 Niro has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. When the ignition turns off, the headlights turn off after a delay timed to allow you to securely get to your front door. The 500X only offers an automatic headlight on/off feature as an extra cost option.

When the Niro SX 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.

Standard air-conditioned seats in the Niro SX 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 Niro SX’s standard 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 Niro 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 Niro 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 Niro EX/SX 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 Kia Niro EX/SX has a standard wireless phone charging system (Qi) in the center console. The 500X doesn’t offer wireless personal charging.
