The MX-5 Miata has standard Secondary Collision Reduction, which automatically apply 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.
The MX-5 Miata’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the Emira.
The MX-5 Miata 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 MX-5 Miata has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Lotus charges extra for Rear Cross Traffic Alert on the Emira.
Both the MX-5 Miata 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 and daytime running lights.
