Speed Demon is a Bronze-level PSN trophy in Gran Turismo 5, Gran Turismo 6 and Gran Turismo 7. It is achieved upon reaching a top speed of 300 km/h (186 mph) in the PlayStation 3-era games, or 500 km/h (311 mph) in GT7.
A different version of the Speed Demon trophy in Gran Turismo Sport requires that the player earn gold in Speed-type challenges in Mission Challenges.
