Opel Blitz was the name given to various German light and middle-weight trucks built by Opel between 1930 and 1975.
During the years preceding the Second World War, Opel was Germany's largest truck producer. The Blitz name was first applied to an Opel truck in 1930 and by 1934 there were four base versions offered of the 1 tonne model along with fourteen versions of the larger 2/2½ tonne trucks.
A half-tracked version, using tracks and suspension based on that used on the Universal Carrier, was also produced as the Opel Maultier (mule). In Europe this truck was considered General Motors contribution to German successes.
It is also argued that Opel, a subsidiary of GM, used forced labor to reap unprecedented profits. However, to what degree GM controlled Opel at the time can be argued, but it is clear that GM did in fact play a role in giving Nazi Germany the Opel Blitz truck.
