The MX-5 Miata has standard Smart City Brake Support, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The TT doesn't offer collision warning or crash mitigation brakes.
The MX-5 Miata’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The TT doesn’t offer a lane departure warning system.
To help make backing out of a parking space safer, the MX-5 Miata’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The TT doesn’t offer a cross-path warning system.
Both the MX-5 Miata and the TT 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, daytime running lights, blind spot warning systems and rearview cameras.
