Bruetsch Mopetta, built in Germany 1956-1958
Bruetsch Zwerg, built in Germany 1955-1958
Brutsch Avolette, built in France c1956, and then renamed L'Avolette 
Egon Brütsch was a wealthy German racer of motorcycles and automobiles who built performance sports cars powered by Maserati and Bugatti engines. In 1950 he began design of a microcar with a fibreglass body, similar in concept to the Messerschmitt and Goggomobil microcars.
Quite a number of very different designs eventuated, powered by engines which included a 48cc JLO, 200cc Sachs, 250cc Maico and a 400cc Lloyd . Reportedly a deal with Opel to build large quantities of one of his designs, the Rollera, fell through at the last moment.
The French Avolette firm built the V2-N powered by a Heinkel 175 or a powerful 500cc two-stroke Fiat. Bruetsch was also the designer of the Burgfalke, initially licenced to Victoria.
None of the Bruetsch designs met success in the marketplace, the last being built around 1958.
1. Brutsch is correct spelling for the French machine. L'Avolette was possibly built until 1958
2. Lloyd Motoren Werke GmbH, a division of Borgward.
3. It has been stated that Brütsch machines were licenced in the UK and built under the name of Tourette. This is not the case. The Tourette, although similar in appearance, was conceptualised some years earlier than the Breutsch.
