This can be completed in the "Airport Terminal D" Drift Event. Make sure you set the event difficulty to hard for the Hard Way to Hell achievement / trophy. Use any drift vehicle you are comfortable with and keep an eye on your multiplier. You should be able to reach a multiplier of 50 if you do not hit any walls and maintain your drifts. This may take a couple tries, but keep at it.
