1954 Porsche 356 Glöckler Coupé
- Engine
- 1.5L four-cam flat-four (Fuhrmann vertical-shaft design), four-speed gearbox

The sole coupe variant among Walter Glöckler's six Porsche-based racing specials, this 1954 Glöckler-Porsche 356 was built on an original Pre-A chassis with aluminum bodywork by C.H. Weidenhausen — the same coachbuilder responsible for the first two Porsche 550 RS Prototypes. Powered by an early Fuhrmann four-cam engine, it debuted at the 1954 Liège–Rome–Liège rally. Acknowledged as a direct predecessor of the Porsche 550, the car was repatriated to Germany in 1993 and comprehensively restored after 2005.
