The Juwel 6 was powered by a newly developed 6-cylinder side-valve engine of 2.46 litres, mounted ahead of the driver and delivering 45 hp at 3,200 rpm.
Power was delivered to the rear wheels through a single plate dry clutch and a three-speed gear box controlled using a centrally positioned floor-mounted gear stick.
The car sat on a U-profile pressed steel chassis with rigid axles and semi-elliptical leaf springing.
A front-wheel drive replacement had been identified in 1931, but for cost reasons this never passed beyond the prototype phase, though it may have provided inspiration for the Audi Front launched by a leading competitor two years later in 1933.
