Early cars
Hans Trippel, born near Darmstadt in 1908, was a German designer and racing driver who is best remembered for amphibious cars [5]. According to the Wheatcroft Collection, he built his first amphibious prototype in 1932 and began producing the SG6 at Homburg, in the Saar, in 1934 [2]. Hagerty also dates the SG6 design to 1934, while Wikipedia, drawing on German sources, says Trippel began designing prototypes in 1935, set up a factory in Hamburg in 1936 and built the SG6 from 1937 [1][4].
Rather than fitting a floating body onto a car chassis, Trippel built the SG6 around a streamlined tub-shaped body with the running gear fitted inside [4]. Early cars had four-wheel drive, an Adler four-cylinder engine and a propeller for use in water [2][3]. Trippel aimed them at civilian buyers such as large estates, forestry work and hunting and fishing parties [2]. In September 1938, as publicity, an SG6 drove from Hamburg to Naples and then crossed about 28 km (17 mi) of open water to the island of Capri [4].
Wartime production
The German army placed an order for 20 SG6s, and military versions followed [4]. After Germany defeated France in 1940, Trippel took control of the Bugatti factory at Molsheim in Alsace [2][5]. Wikipedia cites a lease signed on August 12, 1940, that moved his company's headquarters there [4]. The SG6/41, built at Molsheim from 1941, had an Opel 2.5 L six-cylinder engine of 55 hp and, by Wikipedia's figures, weighed 1,660 kg (3,660 lb) and reached 95 km/h (59 mph) on land and 14.5 km/h (9 mph) in water [4]. The Wheatcroft Collection gives the military models a top speed of 50 mph (80 km/h) and says Molsheim built about 20 a month [2].
Estimates of total SG6 output range from about 800 to about 1,000 [2][3][4]. Production ended in 1943, as the army turned to the lighter and cheaper Volkswagen Type 166 Schwimmwagen [4]. The French site MVCG notes that the army ordered roughly fifteen times as many Volkswagens as Trippels [3].
Trippel was an active supporter of the Nazi regime and a member of the SA, according to Wikipedia, and the Wheatcroft account gives him the rank of Obersturmbannführer [5][2]. After the war, French authorities held him for about three years [3][5].
Link to the Amphicar
Trippel went on testing amphibious designs in the 1950s [3]. At the 1959 Geneva motor show he showed a prototype called the Eurocar Alligator, which first used a 948 cc Austin A35 engine and then the 1,147 cc engine of the Triumph Herald [1]. Hagerty reports that he persuaded the German government to back the project as an export opportunity [1].
The design became the Amphicar 770, introduced at the 1961 New York Auto Show and built by the Quandt Group at Lübeck and Berlin-Borsigwalde [6]. Hagerty gives its price as about DM 10,000 in 1961 [1]. About 3,878 Amphicars were made, and the last were sold in 1968 [1][6].
Survivors
Few SG6s survive. One is displayed at the Musée des Blindés, the tank museum in Saumur, France, and the Wheatcroft Collection owns another that passed a swimming test in 2012 [3][4][2].
