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 Encore GX 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 Encore GX doesn’t offer Downhill Brake Control.

Both the Niro and Encore GX have rear cross-traffic warning, but the Niro has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Encore GX’s Rear Cross Traffic Alert doesn’t automatically brake.

The Niro’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Encore GX doesn’t offer a driver alert monitor.

Both the Niro and the Encore GX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available front and rear parking sensors.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Niro is 6.1% to 6.7% less likely to roll over than the Encore GX.

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 Encore GX’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

Kia’s powertrain warranty covers the Niro 5 years and 40,000 miles longer than Buick covers the Encore GX. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Encore GX ends after only 5 years or 60,000 miles.

Reliability

A hardened steel chain, with no maintenance needs, drives the camshafts in the Niro’s engine. A rubber cam drive belt that needs periodic replacement drives the Encore GX’s camshafts. If the Encore GX’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Kia vehicles are better in initial quality than Buick vehicles. J.D. Power ranks Kia fourth in initial quality, above the industry average. With 1 more problems per 100 vehicles, Buick is ranked fifth.

From surveys of all its subscribers, Consumer Reports’ March 2025 Auto Issue reports that Kia vehicles are more reliable than Buick vehicles. Consumer Reports ranks Kia 2 places higher in reliability than Buick.

Engine

The Niro’s 1.6 DOHC 4-cylinder hybrid produces 2 more horsepower (139 vs. 137) and 33 lbs.-ft. more torque (195 vs. 162) than the Encore GX’s standard 1.2 turbo 3-cylinder. The Niro’s 1.6 DOHC 4-cylinder hybrid produces 21 lbs.-ft. more torque (195 vs. 174) than the Encore GX’s optional 1.3 turbo 3-cylinder.

As tested in Consumer Reports the Kia Niro is faster than the Buick Encore GX 1.3 turbo 3-cylinder:

	Niro	Encore GX
Zero to 30 MPH	3.3 sec	3.4 sec
Zero to 60 MPH	8.9 sec	9.4 sec
45 to 65 MPH Passing	5.6 sec	6.4 sec
Quarter Mile	16.9 sec	17.3 sec
Speed in 1/4 Mile	84 MPH	82 MPH

Fuel Economy and Range

On the EPA test cycle the Niro gets better mileage than the Encore GX:

			MPG
Niro
	FWD	1.6 4-cyl. Hybrid	53 city/54 hwy
		Touring 1.6 4-cyl. Hybrid	53 city/45 hwy
Encore GX
	FWD	1.2 turbo 3-cyl.	30 city/31 hwy
		1.3 turbo 3-cyl.	29 city/31 hwy
	AWD	1.3 turbo 3-cyl.	26 city/28 hwy

The Niro has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Encore GX. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

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 more internally efficient than a CVT but just as easy to drive. The Encore GX doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

The Niro stops shorter than the Encore GX:

	Niro	Encore GX
60 to 0 MPH	121 feet	122 feet	Motor Trend

Suspension and Handling

For superior ride and handling, the Kia Niro has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Buick Encore GX has a rear torsion beam axle, with a semi-independent rear suspension.

The Niro has standard front and rear stabilizer bars, which help keep the Niro flat and controlled during cornering. The Encore GX’s suspension doesn’t offer a rear stabilizer bar.

For a smoother ride and more stable handling, the Niro’s wheelbase is 5.1 inches longer than on the Encore GX (107.1 inches vs. 102 inches).

For better handling and stability, the average track (width between the wheels) on the Niro is 1.3 inches wider in the front and 1.3 inches wider in the rear than the track on the Encore GX.

The Niro SX handles at .84 G’s, while the Encore GX AWD pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the Niro’s turning circle is 2.1 feet tighter than the Encore GX’s (34.8 feet vs. 36.9 feet).

Passenger Space

The Niro has 10.8 cubic feet more passenger volume than the Encore GX (105.1 vs. 94.3).

The Niro has .8 inches more front headroom, .6 inches more front legroom, 1.4 inches more front hip room, .8 inches more front shoulder room, 1.5 inches more rear headroom, 3.8 inches more rear legroom, 2.3 inches more rear hip room and 1.8 inches more rear shoulder room than the Encore GX.

Cargo Capacity

The Niro has a larger cargo volume with its rear seat folded than the Encore GX with its rear seat folded (63.7 vs. 50.2 cubic feet).

Servicing Ease

The Niro uses gas struts to support the hood for easier service access. The Encore GX 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

The Niro SX’s front power windows both open or close with one touch of the switches. The Encore GX’s front passenger window doesn’t close automatically.

On a hot day the Niro’s driver can lower the front windows from a distance using the keyless remote. The driver of the Encore GX can only operate the windows from inside the vehicle, with the ignition on.

Both the Kia Niro and Buick Encore GX offer exterior mirrors that can be folded to provide convenience. The Niro offers available power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the Encore GX’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

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 Encore GX doesn’t offer air-conditioned seats.

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 Encore GX Avenir.

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