Car and Driver |
Tires and Wheels
The Niro EV’s tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the bZ4X XLE’s standard 60 series tires.
Suspension and Handling
The Niro EV Wave handles at .87 G’s, while the bZ4X Limited AWD pulls only .80 G’s of cornering force in a Car and Driver skidpad test.
For better maneuverability, the Niro EV’s turning circle is 5.2 feet tighter than the bZ4X’s (34.8 feet vs. 40 feet).
Chassis
The Kia Niro EV may be more efficient, handle and accelerate better because it weighs about 550 to 750 pounds less than the Toyota bZ4X.
The Niro EV is 10.6 inches shorter than the bZ4X, making the Niro EV easier to handle, maneuver and park in tight spaces.
The front grille of the Niro EV uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The bZ4X doesn’t offer active grille shutters.
Passenger Space
The Niro EV has 5.3 cubic feet more passenger volume than the bZ4X (99.7 vs. 94.4).
The Niro EV has 1.9 inches more front headroom, 1 inch more rear headroom, 1.6 inches more rear legroom and 7.9 inches more rear hip room than the bZ4X.
Cargo Capacity
The Niro EV has a larger cargo volume with its rear seat folded than the bZ4X with its rear seat folded (63.7 vs. 56.9 cubic feet).
Servicing Ease
The Niro EV uses gas struts to support the hood for easier service access. The bZ4X 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 EV Wave, 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 bZ4X doesn’t offer a memory system.
The Niro EV Wave’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 bZ4X doesn’t offer an easy entry system.
The Niro EV offers an optional heads-up display that projects speed 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 bZ4X doesn’t offer a heads-up display.
To improve rear visibility by keeping the rear window clear, the Niro EV has a standard rear wiper. The bZ4X doesn’t offer a rear wiper.
When the Niro EV Wave 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 bZ4X’s mirrors don’t automatically adjust for backing.
Both the Kia Niro EV and Toyota bZ4X offer exterior mirrors that can be folded to provide convenience. The Niro EV 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 bZ4X’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.
The Niro EV Wave has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The bZ4X doesn’t offer a house-current electrical outlet.
The Niro EV Wave’s Smart Park Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart Park Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The bZ4X Limited’s automatic parking system does not offer parking by remote control.
Economic Advantages
Insurance will cost less for the Niro EV owner. The Complete Car Cost Guide estimates that insurance for the Niro EV will cost $555 to $1990 less than the bZ4X over a five-year period.
The Niro EV will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Niro EV will retain 54.32% to 55.04% of its original price after five years, while the bZ4X only retains 51.93% to 52.49%.
