The Autobahn ring is based on the famous German highways. It is a very high speed circuit. Rear wheel drive and cars with good top end speed will do well on the events here.
Drifting on the harder course (right) is very hard. The hills on both sides of the tracks mean that if you hit them, you run a major risk of totaling your car.
Speed challenges here are the easiest you will come up against. It is very high speed but relatively simple corners mean that there isn't much danger, unless you misjudge the line then you will have a very big crash.
