The Isabella was to have been marketed as the BORGWARD HANSA 1500 but the Isabella name was used on test vehicles and proved popular with engineering staff and media. The production car was subsequently renamed and only the first few hundred examples were built without Isabella badging. Hansa badging was also used through to 1957.
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.

THE ISABELLA AT LAUNCH
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 ,
The advertised launch price of DM 7,265 was higher than that of competitor family sedans from Opel and Ford , but significantly less than Mercedes Benz was asking for their 180 model. In view of the car's spacious cabin and impressive performance, the pricing was perceived as very competitive. A road test at launch reported a maximum speed of 130 km/h (81 mph) and fuel consumption of 8.4 l/100 km. The testers described the modern structure of the car in some detail: they particularly liked the wide cabin with its large windows, and they commended the effectiveness of the brakes. The inclusion of a cigarette lighter and a clock also attracted favourable mention. Unlike the Mercedes 180 however, (and unlike its predecessor) the Isabella was only delivered with two-doors.
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. Ground clearance was 6.9".
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.
A year after presenting the sedan, Borgward presented the Isabella estate version.
Also introduced in 1955 was a two-door cabriolet, known as the
Isabella TS and featuring a more powerful 75 bhp (56 kW) motor.
Production of the cabriolet was contracted to the firm Karl Deutsch in
Initial sales volumes were not maintained. Responding to a sales decline of almost a third in 1955 and 1956, Carl Borgward decided to produce a more beautiful Isabella with a shortened roof line. The Borgward Isabella Coupé was developed, and the four hand built prototypes were well received by the press. Borgward gave one of these prototypes to his wife, Elisabeth, who would continue to drive it into the 1980s. Commercial production of the coupé, powered by the more powerful TS version of the engine first seen in the cabriolet, commenced in January 1957. The coupe appears to have achieved its marketing objective of further distancing the Isabella’s image from similarly sized competitors from Opel and Ford. By 1958, the more powerful 75 bhp (56 kW) TS motor had also found its way into the more upmarket Isabella sedan and estate versions.
Vehicles were exported to several markets, including Australia, New Zealand and Malaya, where only 10 examples were sold.

THE ISABELLA IN COMPETITION
English Racing driver and tuner Bill Blydenstein raced a Borgward Isabella in the 1950s with some success.
END OF PRODUCTION
At the time of Borgward’s controversial bankruptcy in 1961, the
firm carried a substantial stock of unsold Isabellas. Nevertheless,
the model's production at the
Borgward enjoyed a brief afterlife: the production line was sold and
shipped to Mexico where later during the 1960s the P100 (Big Six) was
produced. The Isabella was never produced in Mexico. Back in the
German market, BMW’s stylish new 1500 , launched by the Bavarians in
1961, convincingly filled the niche vacated by the Isabella, and was
credited by at least one commentator with having rescued
