Tires and Wheels

For better traction, the Clarity Electric has larger tires than the Prius Prime (235/45R18 vs. 195/65R15).

The Clarity Electric’s tires provide better handling because they have a lower 45 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 Clarity Electric has standard 18-inch wheels. Only 15-inch wheels are available on the Prius Prime.

Suspension and Handling

For a smoother ride and more stable handling, the Clarity Electric’s wheelbase is 2 inches longer than on the Prius Prime (108.3 inches vs. 106.3 inches).

For better handling and stability, the track (width between the wheels) on the Clarity Electric is 2 inches wider in the front and 1.9 inches wider in the rear than on the Prius Prime.

The Clarity Electric’s front to rear weight distribution is more even (51.1% to 48.9%) than the Prius Prime’s (55.5% to 44.5%). This gives the Clarity Electric more stable handling and braking.

Passenger Space

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

The Clarity Electric has 9 cubic feet more passenger volume than the Prius Prime (100.5 vs. 91.5).

The Clarity Electric has 2.1 inches more front hip room, 5.5 inches more front shoulder room, 2.8 inches more rear legroom, 4 inches more rear hip room and 4.3 inches more rear shoulder room than the Prius Prime.


When two different drivers share the Clarity Electric, the memory seats make it convenient for both. Each setting activates different, customized memories for the driver’s seat position. The Prius Prime doesn’t offer memory seats.

If the windows are left open on the Clarity Electric 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. The driver of the Prius Prime can only operate the windows from inside the vehicle, with the ignition on.

The Clarity Electric 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 Clarity Electric has standard extendable sun visors. The Prius Prime doesn’t offer extendable visors.

Both the Clarity Electric and the Prius Prime have standard heated front seats. The Clarity Electric also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Prius Prime.

The Clarity Electric’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 Clarity Electric and the Prius Prime offer rear vents. For greater rear passenger comfort, the Clarity Electric 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.
