The 2026 Kia Niro HEV offers four distinct trims, each designed for a different type of buyer. If you're looking for efficient hybrid transportation with room for the family, the Niro HEV lineup delivers up to 4.4 L/100 km combined fuel economy. Here's how the LX, EX, EX PREMIUM, and SX trims stack up.
All four trims share the same 1.6L hybrid powertrain - a gasoline engine paired with a permanent magnet synchronous motor for a combined 139 hp and 195 lb-ft of torque. Power goes to the front wheels, and every Niro HEV comes with Drive Mode Select to adjust throttle response and steering feel. Cargo space is generous across the board: 646 litres with the rear seats up, expanding to 1,805 litres when you fold them down - enough for a full grocery run, hockey bags, and camping gear.

LX: The Value Play
The LX is built for buyers who want hybrid efficiency without paying for extras they won't use. It delivers 4.4 L/100 km combined - competitive for a small crossover with this much interior space. You get 16-inch alloy wheels, an 8-inch display audio system with Apple CarPlay and Android Auto, and a 4.2-inch TFT LCD instrument cluster. Heated front seats and dual-zone automatic climate control are standard, which is rare at this price point.
Safety equipment includes the full suite of collision warning and automatic braking systems - all standard, even on the base LX. Lane keeping and follow assist, forward collision-avoidance assist, blind spot collision-avoidance assist, and rear cross-traffic avoidance assist are included. The rearview camera has dynamic guidelines to help with tight parking spots.
The LX is ideal if you're a commuter or small family who values fuel savings over tech upgrades. It's the most affordable way into the Niro HEV lineup without sacrificing the core hybrid benefits.
EX: The Sweet Spot
The EX adds the tech and convenience features most buyers actually want. You get the 10.25-inch multimedia interface with integrated navigation, a wireless phone charger, and a heated steering wheel. Kia Connect is included, giving you remote start, vehicle status checks, and stolen vehicle tracking from your phone. The seats are upgraded to a cloth and synthetic leather combination, and the steering wheel and shift knob are wrapped in synthetic leather.
Smart cruise control with Stop & Go is standard on the EX - it maintains your set speed and following distance, and can bring the Niro to a complete stop in traffic. Highway driving assist (HDA) adds lane centering to keep you centered in your lane on the highway. Rear parking sensors are included.
Fuel economy remains 4.4 L/100 km combined, same as the LX. The EX is the trim for buyers who want a more refined daily driver without stepping up to the premium trims. If you spend a lot of time in the car, the heated steering wheel and wireless charging make a noticeable difference.
EX PREMIUM: The Family Favourite
The EX PREMIUM builds on the EX with features that make family life easier. The power sunroof opens up the cabin, and the smart power liftgate opens automatically when it detects the key fob - helpful when your hands are full of groceries or sports equipment. The 10.25-inch TFT LCD Supervision instrument cluster replaces the smaller screen from the EX, giving you a larger, clearer view of speed, fuel economy, and hybrid system status.
Inside, the driver's seat gains power adjustment and lumbar support. LED interior lighting is standard, making it easier to find dropped items at night. Front parking sensors are added to the rear sensors from the EX, giving you full coverage when manoeuvring in tight spaces.
Fuel economy is still 4.4 L/100 km combined. The EX PREMIUM is the trim for buyers who want the Niro HEV to feel like a step up from a basic commuter car - more comfort, more convenience, and a more polished interior.
SX: The Premium Experience

The SX is the top trim, built for buyers who want the Niro HEV to feel upscale. It rides on 18-inch alloy wheels and features full LED headlights with LED fog lights. The exterior gets black and chrome accents on the grille and skid plates, plus split-chrome door handles. Laminated front windows reduce road noise, and the power-folding mirrors add a touch of luxury.
Inside, the seats are upgraded to synthetic leather with air-cooling for the front seats - a rare feature in this segment. Heated rear seats are standard, making the SX a better choice for families with kids. The Harman Kardon premium audio system delivers richer sound than the standard setup, and the heads-up display projects speed and navigation directions onto the windshield so you don't have to look down at the cluster.
Digital Key lets you unlock and start the Niro HEV with your smartphone - no key fob required. The driver's seat memory function saves your preferred seating position, and the power-adjustable passenger seat ensures both front occupants can find their ideal position. Rain-sensing wipers and an auto-dimming rearview mirror round out the convenience features.
Fuel economy on the SX is 4.8 L/100 km combined (5.2 L/100 km highway) - slightly higher than the other trims due to the larger wheels and added weight. The SX is the trim for buyers who want the Niro HEV to feel like a premium vehicle, not just an efficient one.

Which Trim Is Right for You?
If you're focused on value and fuel savings, the LX delivers everything you need at the lowest price. If you want a more refined daily driver with navigation and wireless charging, the EX is the sweet spot. Families who need extra convenience will appreciate the power liftgate and larger digital cluster on the EX PREMIUM. And if you want the Niro HEV to feel like a premium vehicle, the SX adds air-cooled seats, premium audio, and a heads-up display.
All four trims share the same efficient hybrid powertrain and generous cargo space. The differences come down to comfort, convenience, and tech.
