Tires and Wheels

For better traction, the Clarity Plug-In Hybrid has larger tires than the Volt (235/45R18 vs. 215/50R17).

The Clarity Plug-In Hybrid’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Volt’s standard 50 series tires.

For better ride, handling and brake cooling the Clarity Plug-In Hybrid has standard 18-inch wheels. Only 17-inch wheels are available on the Volt.

Suspension and Handling

For superior ride and handling, the Honda Clarity Plug-In Hybrid 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 Chevrolet Volt has a rear torsion beam axle, with a semi-independent rear suspension.

The Clarity Plug-In Hybrid has standard front and rear stabilizer bars, which help keep the Clarity Plug-In Hybrid flat and controlled during cornering. The Volt’s suspension doesn’t offer a rear stabilizer bar.

For a smoother ride and more stable handling, the Clarity Plug-In Hybrid’s wheelbase is 2.2 inches longer than on the Volt (108.3 inches vs. 106.1 inches).

For better handling and stability, the track (width between the wheels) on the Clarity Plug-In Hybrid is 1.6 inches wider in the front and .7 inches wider in the rear than on the Volt.

The Clarity Plug-In Hybrid’s front to rear weight distribution is more even (57% to 43%) than the Volt’s (58.5% to 41.5%). This gives the Clarity Plug-In Hybrid more stable handling and braking.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Clarity Plug-In Hybrid a Mid-size car, while the Volt is rated a Compact.

The Clarity Plug-In Hybrid has 11.2 cubic feet more passenger volume than the Volt (101.5 vs. 90.3).

The Clarity Plug-In Hybrid has 1.3 inches more front headroom, .1 inches more front legroom, 2.1 inches more front hip room, 3.2 inches more front shoulder room, 1.3 inches more rear headroom, 1.5 inches more rear legroom, 4.3 inches more rear hip room and 4.1 inches more rear shoulder room than the Volt.

Cargo Capacity

The Clarity Plug-In Hybrid has a much larger trunk than the Volt (15.5 vs. 10.6 cubic feet).


When two different drivers share the Clarity Plug-In Hybrid Touring, the memory seats make it convenient for both. Each setting activates different, customized memories for the driver’s seat position. The Volt doesn’t offer memory seats.

The Clarity Plug-In Hybrid’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Volt’s passenger windows don’t close automatically.

If the windows are left open on the Clarity Plug-In Hybrid 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 Volt can only close the windows from inside the vehicle, with the ignition on.

The Clarity Plug-In Hybrid’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Chevrolet charges extra for heated mirrors on the Volt.

The Clarity Plug-In Hybrid’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 Volt doesn’t offer dual zone air conditioning.

Both the Clarity Plug-In Hybrid and the Volt offer rear vents. For greater rear passenger comfort, the Clarity Plug-In Hybrid has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Volt doesn’t offer rear air conditioning vents, only heat vents.
