The Sonic has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Impreza doesn’t offer variable-assist power steering.

The Sonic Premier Hatchback handles at .84 G’s, while the Impreza 2.0i Limited 5-door pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The Sonic Premier Hatchback executes Motor Trend’s “Figure Eight” maneuver quicker than the Impreza 2.0i Limited 5-door (27.3 seconds @ .62 average G’s vs. 27.9 seconds @ .6 average G’s).

For better maneuverability, the Sonic LS/LT’s turning circle is .9 feet tighter than the Impreza’s (34.5 feet vs. 35.4 feet).

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

The Sonic LT/Premier’s available front and rear power windows all lower 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 Impreza’s rear power window switches have to be held the entire time to open them fully.

Consumer Reports rated the Sonic’s headlight performance “Good,” a higher rating than the Impreza’s headlights, which were rated “Fair.”

The Sonic 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 Impreza has an automatic headlight on/off feature standard only on the Premium/Sport/Limited.

On extremely cold winter days, the Sonic’s optional (except LS/RS/5-Door) heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Impreza doesn’t offer a heated steering wheel.
