1956 Auto Union DKW F93
Auto Union marketed the model with its distinctive “3=6” designation, claiming the three-cylinder two-stroke engine delivered the same number of power strokes per crankshaft revolution as a six-cylinder four-stroke.
The 54.9 cu in longitudinally mounted engine produced 38 hp at 4,200 rpm, increasing to 40 hp for later versions. A front-wheel-drive layout with the engine positioned ahead of the front axle reduced weight and improved traction.
Introduced for 1956, the F93 featured a wider body than its F91 predecessor, with track increased by nearly four inches to improve stability and interior space.
An oval front grille replaced earlier horizontal slats, while the 92.5-inch wheelbase remained unchanged. A strengthened chassis incorporated improved suspension and braking systems.
A four-speed manual transmission with a column-mounted shifter was standard, with an optional Saxomat automatic centrifugal clutch available.
Auto Union built approximately 137,800 examples through 1959, including sedan, coupe, and estate variants, with 667 cabriolets bodied by Karmann. The model was succeeded by the Auto Union 1000.
