1958 was a turning point for the company. Firstly, it saw the return of the Auto Union brand, represented by the Auto Union 1000, a small saloon. At the same time the Auto Union 1000 Sp, a stylish coupé model, was produced for Auto Union by the Stuttgart coach builders, Baur. Secondly, Daimler-Benz acquired 87% of Auto Union, taking complete control in 1959. The production of DKW motorcycles and two-stroke engines ended almost immediately under Daimler-Benz ownership, who invested heavily in the Ingolstadt plant for Auto Union production, one of the first products of the merged company being the DKW F102 series, which used a Mercedes engine.
