The Dinky Auto-Union Racing Car. Launched twice in the United Kingdom and once, in France, the Auto Union racing car, 23d, first appeared in 1936. The pre-war version had no driver and a baseplate clipped into position, although some later pre-war models did have a driver and a round riveted baseplate. In 1936, the 100mm long model cost 7 old pence, which rose to 23 old pence, 1/11, by the time of the 1946, post-war relaunch.

In the UK version, rear axles extended through the rear wheel cowlings, which did not occur on the French model; mountings were within the cowlings. The ribbed wheel hubs replaced the earlier smooth type and were fitted with black herringbone tyres. Round rivets attached post-war baseplates. While in France, models had a single, sunken, central rivet. In the UK, the racing car came in a range of colours, silver, blue, red, green and yellow. Light green was the only colour used for the French version. The models carried a range of race numbers, 1-6.

In 1935, Auto Union built the actual 16-cylinder racing car for speed trials. Over a flying kilometre, the car reached 316 km/h.
