Using vehicle speed sensors and seat sensors, smart airbags in the Insight deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Insight’s side airbags will shut off if a child is leaning against the door. The Prius’ airbags don’t have smart features and will always deploy full force.

Compared to metal, the Insight’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Toyota Prius has a metal gas tank.

Both the Insight and the Prius have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.

For better traction, the Insight has larger tires than the Prius (215/55R16 vs. 195/65R15).

The Insight’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Prius L Eco/LE’s standard 65 series tires.

For better ride, handling and brake cooling the Insight has standard 16-inch wheels. Smaller 15-inch wheels are standard on the Prius L Eco/LE.

The Insight’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Prius doesn’t offer drift compensation steering.

For better handling and stability, the track (width between the wheels) on the Insight is 1.1 inches wider in the front and 1.4 inches wider in the rear than the average track on the Prius.

The Insight EX handles at .87 G’s, while the Prius L Eco pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The Insight Touring executes Motor Trend’s “Figure Eight” maneuver 1.9 seconds quicker than the Prius L Eco (27 seconds @ .63 average G’s vs. 28.9 seconds @ .55 average G’s).

The Insight EX/Touring has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Prius doesn’t offer a remote starting system.

The Insight’s power parking brake sets with one touch and releases with one touch or automatically. The Prius’ parking brake has to released manually.

The Insight’s power window, power lock and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Prius’ cruise control switches are unlit, making them difficult to find at night and operate safely.

Consumer Reports rated the Insight’s headlight performance “Very Good,” a higher rating than the Prius’ headlights, which were rated “Good.”

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Insight’s headlights were rated “Good” by the IIHS, while the Prius’ headlights are rated “Acceptable.”

The Insight 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 has an automatic headlight on/off feature standard only on the XLE/Limited.

The Insight Touring’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 doesn’t offer dual zone air conditioning.
