This race is located in Showcase Events -> Factory Spec Racing ->Formula Ford Cup at Hockenheimring.
This race requires you to use the Ford Formula Ecoboost 200, a RWD, open-wheeled, single-seat car which is much like an Ariel Atom.
As such, this race is 8 laps long and you start 14th in a field of 24 on the Full Circuit of Hockenheim. It is very easy for the leader to get away from you if you play on harder drivatar difficulty.
This car breaks loose very easy (a lot of snap oversteer on corner exit). To combat this, either let TCS do the work or be very easy and make sure the car is 100% straight before going full bore on the power.
Hopefully this helps, and let me know if there's anything I can improve about this guide!
EDIT2: One user seemed to have a problem popping this if they raced 'dirty', but others have confirmed that dirty racing does NOT usually void the achievement.
