Later on in the early 1970’s AC again had plans to enter the 3 wheeler/economy car market. The prototype again used the single wheel at the front format, this time in a larger fibre glass four seat body. Again the engine was rear mounted (giving better stability on the single front wheel trike layout) and was a fairly powerful twin cylinder 500cc unit made by Steyr Puch. At least 3 prototypes were made. Sadly, it never reached full scale production.
