For enhanced safety, the front and rear seat shoulder belts of the Lexus UX 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 Kia Niro doesn’t offer pretensioners for its rear seat belts.

The Lexus UX 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 Niro doesn’t offer a front passenger side knee airbag.

Using vehicle speed sensors and seat sensors, smart airbags in the UX deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The UX’s side airbags will shut off if a child is leaning against the door. The Niro’s side airbags don’t have smart features and will always deploy full force.

The UX has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Niro 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.

Over 200 people are killed each year when backed over by motor vehicles. The UX offers an optional Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Niro doesn’t offer backup collision prevention brakes.

The UX offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Niro doesn’t offer all-wheel drive.

The UX offers optional Intuitive Parking Assist to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The Niro doesn’t offer a front parking aid.

The UX 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. Only the Niro LXS/LXS SE/Touring SE/EX Premium offers a blind spot warning system.

To help make backing out of a parking space safer, the UX has standard Rear Cross-Traffic Alert, helping the driver avoid collisions. Only the Niro LXS/LXS SE/Touring SE/EX Premium offers rear cross-path warning.

The UX has standard Safety Connect®, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Niro doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the UX and the Niro have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the UX its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The Niro has not been fully tested, yet.

Warranty

The UX’s corrosion warranty is 1 year and unlimited miles longer than the Niro’s (6/unlimited vs. 5/100,000).

Reliability

J.D. Power and Associates rated the UX second among small premium suvs in their 2023 Initial Quality Study. The Niro isn’t in the top three in its category.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Lexus vehicles are more reliable than Kia vehicles. Consumer Reports ranks Lexus second in overall reliability. Kia is ranked 9th.

Engine

The UX’s 2.0 DOHC 4-cylinder hybrid produces 42 more horsepower (181 vs. 139) than the Niro’s 1.6 DOHC 4-cylinder hybrid.

As tested in Motor Trend the Lexus UX is faster than the Kia Niro:

	UX	Niro
Zero to 60 MPH	8.3 sec	9.9 sec
Quarter Mile	16.3 sec	17.4 sec
Speed in 1/4 Mile	87.3 MPH	80.3 MPH

Transmission

The UX 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 Niro doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the UX’s brake rotors are larger than those on the Niro:

	UX	Niro
Front Rotors	12 inches	11 inches
Rear Rotors	11.1 inches	10.3 inches

The UX stops much shorter than the Niro:

	UX	Niro
60 to 0 MPH	128 feet	138 feet	Motor Trend
60 to 0 MPH (Wet)	143 feet	152 feet	Consumer Reports

Tires and Wheels

For better traction, the UX has larger tires than the Niro (225/50R18 vs. 205/60R16).

The UX’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Niro LX/LXS/EX Premium’s standard 60 series tires.

For better ride, handling and brake cooling the UX has standard 18-inch wheels. Smaller 16-inch wheels are standard on the Niro LX/LXS/EX Premium.

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

Suspension and Handling

The UX has variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Niro doesn’t offer variable-assist power steering.

The UX 250h F Sport Handling AWD handles at .80 G’s, while the Niro LXS pulls only .78 G’s of cornering force in a Motor Trend skidpad test.

The UX 250h F Sport Handling AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the Niro LXS (28.1 seconds @ .62 average G’s vs. 28.6 seconds @ .58 average G’s).

For better maneuverability, the UX’s turning circle is .6 feet tighter than the Niro’s (34.2 feet vs. 34.8 feet).

Passenger Space

The UX has .3 inches more front legroom, .1 inches more front hip room and 4 inches more rear hip room than the Niro.

Cargo Capacity

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

To make loading and unloading groceries and cargo easier when your hands are full, the UX’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The Niro doesn’t offer a power or hands-free opening liftgate.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Kia. J.D. Power ranks Lexus first in service department satisfaction. With a 63% lower rating, Kia is ranked 26th.

Ergonomics

When three different drivers share the UX F Sport Handling, the memory seats and mirrors make it convenient for all three. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The Niro doesn’t offer a memory system.

The UX’s optional 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 Niro doesn’t offer an easy entry system.

The UX offers an optional heads-up display that projects speed, tachometer, warning 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 Niro doesn’t offer a heads-up display.

The UX’s power parking brake sets with one touch and releases with one touch or automatically. The Niro’s parking brake has to be released manually.

The UX’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Niro’s standard rear power window switches have to be held the entire time to open them fully. Only its driver’s window closes automatically.

If the windows are left open on the UX the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Lexus service department.) The driver of the Niro can only operate the windows from inside the vehicle, with the ignition on.

The UX Premium/F Sport’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Niro’s manually variable intermittent wipers have to be constantly adjusted.

The UX’s LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the Niro’s standard projector halogen headlights and light instantly. LED lights also last over twenty times longer than halogen.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The UX offers available headlight washers to keep headlight output high. The Niro doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the UX offers optional cornering lights to illuminate around corners when the turn signals are activated. The Niro doesn’t offer cornering lights. The UX F Sport also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The UX’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Kia only offers heated mirrors on the Niro Touring SE/EX Premium.

The UX’s optional 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 Niro offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the UX and the Niro offer rear vents. For greater rear passenger comfort, the UX has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Niro doesn’t offer rear air conditioning vents, only heat vents.
