For enhanced safety, the front and rear seat shoulder belts of the Honda Prelude have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Toyota GR86 doesn’t offer pretensioners for its rear seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Prelude are reminded to check the back seat. The GR86 doesn’t offer a back seat reminder.
The Honda Prelude has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GR86 doesn’t offer a front passenger side knee airbag.
Using vehicle speed sensors and seat sensors, smart airbags in the Prelude deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Prelude’s side airbags will shut off if a child is leaning against the door. The GR86’s side airbags don’t have smart features and will always deploy full force.
The Prelude has a standard Post-Collision Braking System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GR86 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The Prelude has standard Parking Sensors to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The GR86 doesn’t offer a front parking aid.
The Prelude has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the GR86 Premium/Yuzu Edition offers a blind spot warning system.
To help make backing out of a parking space safer, the Prelude has standard Cross Traffic Monitor, helping the driver avoid collisions. Only the GR86 Premium/Yuzu Edition offers Rear Cross Traffic Alert.
Both the Prelude and the GR86 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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.
