The Adler Standard 8 is a large passenger car introduced in 1928 by the Frankfurt auto-maker, Adler.[1] It was a big eight cylinder "limousine" (saloon) closely modelled on the manufacturer's Standard 6 which had first appeared in public in October 1926. However the Standard 8 had a longer 3325 mm wheelbase as well as a 50 mm wider track. Although it closely resembled the Standard 6, the Standard 8 was larger all round. The Standard 8 engine had eight cylinders, but individually the cylinder dimensions, at 75 mm x 110 mm, were identical to those on the six cylinder car as well as on the four cylinder with the Adler Favorit which appeared in 1929.
The structure of the Standard 8 was conservative, with a tall six-light body mounted on an overslung chassis with rigid axles. In these respects, as with the engine, it closely resembled the smaller Adler Standard 6. Just two standard bodied cars were advertised at launch, being the Large 4 door "Limousine" (saloon/sedan) and a 2+2 seater cabriolet priced respectively at 10,800 and 11,500 Marks. The Adler Standard 8 was conservatively engineered and attractively priced: the comparably sized but more powerful and technically innovative 4622 cc Mercedes-Benz 18/80 Typ Nürburg 460 came with an advertised price of 15,000 Marks for a Pullman-Limousine bodied car.[2]
