1956 Borgward Isabella
Despite its aspirational positioning in the marketplace, the Isabella had a smaller engine (and was marginally shorter) than its immediate predecessor, the Borgward Hansa. Late in 1952, the firm had launched their six cylinder Hansa 2400 model. The larger car never found many buyers; but in 1954, it made commercial sense to keep the two models from competing too directly with each other.
11,150 Isabellas were produced in 1954, an early indicator that commercially this would be the most successful Borgward ever. The early cars enjoyed an enthusiastic reception in the market place. Unfortunately, early models were afflicted by teething troubles, reflecting a rushed development schedule, and the marketplace would later prove unforgiving as Borgward's Stuttgart based rival, Daimler-Benz demonstrated that new models did not have to involve customers experiencing such problems.
The Isabella was constructed without a separate chassis, applying the monocoque technique which during the 1950s was becoming the norm. Like its predecessor, the car was designed with a modern ponton, three-box design, but the line of the Isabella was more curvaceous than that of the first Hansa, and the car’s body made greater use of chrome trim. The Isabella featured a swing axle at the back: it was supported by coil springs on all four wheels. The four-cylinder 1493 cc engine had a claimed power output of 60 bhp (45 kW), and was connected by means of a then innovative hydraulic clutch to the four speed full synchromesh gear box. Gear changes were effected by means of a column mounted lever.
