The Goggomobil T250 was introduced by Glas at the 1954 IFMA international bicycle and motorcycle show. The T250 was a conventional-looking two door sedan with a rear-mounted 245 cc air-cooled two-stroke straight twin engine.
Design changes were made to the T250 in 1957. Two windshield wipers were used instead of the earlier system with one wiper, and the sliding windows in the doors were changed to wind-up windows. Also at this time the T300 and T400 became available; these had larger engines of 300 cc and 400 cc respectively.
The last design change for the T sedan came in 1964, when the rear-hinged suicide doors were replaced by conventional front-hinged doors.
214,313 sedans were built when production ended on 30 June 1969.
