During initial release, the only way to get this is as follows
Navigate to Season 1 Episode 1 " The Holy Trinity " under the Singleplayer menu
Use " Scene Select " to navigate to the "Scene 15"
( The McLarent P1 from this scene is the easiest to do it )
The very first camera at the end of the straight is ideal to touch 160 mph.
Fully press the throttle - R2
Use very very minimal steering towards left to stay on track till you reach the camera at 160.
The Trophy pops immediately and you can crash after you pass the camera.
