The Wartburg was a car marque manufactured in East Germany.
The name "Wartburg" derives from Wartburg Castle on one of the hills overlooking the town of Eisenach where the cars were manufactured.
From the 1950s, Wartburgs had a three-cylinder two-stroke engine with only seven major moving parts (three pistons, three connecting rods and one crankshaft).
