Car and Driver

Tires and Wheels

For better traction, the Niro EV has larger tires than the Prius Prime (215/55R17 vs. 195/65R15).

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 Prius Prime’s standard 65 series tires.

For better ride, handling and brake cooling the Niro EV has standard 17-inch wheels. Only 15-inch wheels are available on the Prius Prime.

Suspension and Handling

The Niro EV has standard front and rear gas-charged shocks for better control over choppy roads. The Prius Prime’s suspension doesn’t offer gas-charged shocks.

For better handling and stability, the track (width between the wheels) on the Niro EV is 1.8 inches wider in the front and 1.8 inches wider in the rear than on the Prius Prime.


The Niro EV is 10.7 inches shorter than the Prius Prime, making the Niro EV easier to handle, maneuver and park in tight spaces.

Passenger Space

The Niro EV has standard seating for 5 passengers; the Prius Prime can only carry 4.

The Niro EV has 5.1 cubic feet more passenger volume than the Prius Prime (96.6 vs. 91.5).

The Niro EV has .7 inches more front headroom, 1.8 inches more front shoulder room, .5 inches more rear headroom, 2.6 inches more rear legroom and 2.1 inches more rear shoulder room than the Prius Prime.


The power windows standard on both the Niro EV and the Prius Prime have locks to prevent small children from operating them. When the lock on the Niro EV is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Prius Prime prevents the driver from operating the other windows just as it does the other passengers.

To improve rear visibility by keeping the rear window clear, the Niro EV has a standard rear wiper. The Prius Prime doesn’t offer a rear wiper.

The Niro EV has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The Prius Prime has an automatic headlight on/off feature standard only on the Premium/Advanced.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Niro EV has standard extendable sun visors. The Prius Prime doesn’t offer extendable visors.

When the Niro EV with available tilt-down mirrors 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 Prius Prime’s mirrors don’t automatically adjust for backing.

Standard air-conditioned seats in the Niro EV EX Premium keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Prius Prime doesn’t offer air-conditioned seats.

The Niro EV’s 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. The Prius Prime doesn’t offer dual zone air conditioning.

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