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 Emira doesn’t offer knee airbags.
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 Emira 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.
Over 200 people are killed each year when backed over by motor vehicles. The Prelude has standard Low Speed Braking Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Emira doesn’t offer backup collision prevention brakes.
The Prelude’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Emira.
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. A system to reveal vehicles in the Emira’s blind spot costs extra.
To help make backing out of a parking space safer, the Prelude has standard Cross Traffic Monitor, helping the driver avoid collisions. Lotus charges extra for Rear Cross Traffic Alert on the Emira.
Both the Prelude and the Emira have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights and rear parking sensors.
