Overview
Wendler was a German coachbuilding company based in Reutlingen, Württemberg. Erhard Wendler established the business in 1840 as a carriage factory, placing it within the long tradition of specialist vehicle makers that constructed bespoke bodies rather than complete automobiles. The company initially concentrated on horse-drawn carriages. During the early 1920s it expanded into motor-vehicle body construction, a transition associated with designer Helmut Schwandner and the broader decline of the carriage trade. Wendler developed a reputation for individually styled and technically specialized bodies. Its output remained relatively small compared with mass-production manufacturers: approximately 60 bodies were produced during the 1920s, while annual production in the 1930s is reported at roughly 250 to 270 bodies. The company employed around 100 people during that period. Its customers included private and institutional buyers; one documented 1937 customer was the architect Wilhelm Ritter von Graf. After the Second World War, Wendler resumed coachbuilding and produced bodies in the then-modern ponton form, characterized by integrated front and rear fenders and a more aerodynamic, unified body profile. Series production continued until the end of the 1950s. As the automotive industry increasingly standardized body manufacturing and shifted toward high-volume production, Wendler moved away from regular series work and focused primarily on repairs and specialist construction. Porsche became one of Wendler's most significant automotive customers. Wendler produced lightweight alloy bodies for the Porsche 550 racing and sports car, with sources reporting 90 bodies and other accounts stating that the total exceeded 100. The relationship also led to experimental work. For the 1961 24 Hours of Le Mans, Wendler designed a Porsche-based coupé, although that proposed car was never built. The company subsequently developed its own Porsche-based automobile, designated W-RS 001. In its later years Wendler worked in vintage-car restoration and special-purpose construction, including armored limousines. These activities preserved the company's role as a low-volume specialist rather than a conventional automobile manufacturer. Wendler became insolvent in 2000. Operations continued for a period under the name Pgam AG, but the business ultimately closed. The brand is therefore historically important primarily for German bespoke coachbuilding, its postwar specialist work, and its production of lightweight Porsche bodies rather than for large-scale vehicle manufacturing.
History
Erhard Wendler opened the company in Reutlingen in 1840 as a carriage factory. Its first business was the construction of horse-drawn carriages, but the spread of motor vehicles created an opportunity for traditional carriage makers to adapt their skills to automobile bodies. Wendler began producing car bodies in the early 1920s. Designer Helmut Schwandner is associated with this strategic and technical reorientation. The company's interwar production remained small and bespoke. Around 60 bodies were built during the 1920s, and output rose to approximately 250 to 270 bodies during the 1930s. The workforce was about 100 employees. Wendler served individual clients and other customers requiring custom bodywork; the architect Wilhelm Ritter von Graf is documented as a customer in 1937. Following the Second World War, Wendler restarted car-body production. Its postwar bodies included ponton designs, reflecting the period's transition toward integrated, aerodynamic vehicle forms. The company maintained series production through the end of the 1950s, but the increasing dominance of standardized factory-built bodies reduced the market for independent coachbuilders. Wendler consequently concentrated more heavily on repairs and other specialist work. A major chapter in the company's history was its relationship with Porsche. Wendler manufactured lightweight alloy bodies for the Porsche 550. The commonly cited figure is 90 bodies, although other accounts report a total of more than 100. Wendler also designed a Porsche coupé for the 1961 24 Hours of Le Mans; the proposed car was not constructed. The company then pursued its own Porsche-based design, the W-RS 001. Later activities included restoration of historic vehicles and special construction, notably armored limousines. These services represented the continuing value of coachbuilding expertise in a market no longer centered on ordinary series-production bodies. Wendler entered insolvency in 2000. The business continued under the name Pgam AG for a time before closing permanently. Its surviving historical significance rests on its long continuity from carriage manufacture to automobile coachbuilding, its bespoke and lightweight bodywork, and its Porsche-related projects.

Coachbuilt automotive bodies · 1920
Custom car bodies
Wendler's core automotive business was the construction of low-volume and bespoke bodies for motor vehicles. The company transferred craftsmanship developed in carriage production to automobile design, serving customers who required individualized styling or specialist fabrication rather than standardized mass-produced bodies.
Postwar car bodies · 1945
Ponton-style bodies
After the Second World War, Wendler produced bodies in the ponton form. This design integrated the fenders into a smoother overall body shape and represented the modern postwar direction of passenger-car styling. Wendler continued series production of such specialist bodies until the end of the 1950s.
Lightweight sports-car bodies
Porsche 550 light-alloy bodies
Wendler built lightweight alloy bodies for Porsche 550 vehicles. The documented production figure is 90 bodies, although other accounts give a total of more than 100. This work is among the company's most notable contributions to specialist sports-car and competition-car construction.
Porsche-based special automobile
W-RS 001
