The Borgward Isabella is a car produced between 1954 and 1962 by Carl F. W. Borgward GmbH. The model was to be marketed as the Borgward Hansa 1500, but the name Isabella was used on test vehicles and proved popular with technical staff and the media. The car was subsequently renamed and only the first few hundred examples were produced without the Isabella badge. Despite its ambitious market position, the Isabella had a smaller engine than its predecessor, the Borgward Hansa.

The car was sold as a 2-door sedan, convertible, station wagon, 2+2 coupe, 2+2 convertible and 2-door pickup. It was powered by a 1.5-litre I4 engine with 75 hp (55 kW), which was mated to a 4-speed manual gearbox. Given the spacious cabin and impressive performance, the price of the car was perceived as very competitive. The model was able to reach a speed of 130 km/h with a consumption of 8.4 l/100 km.
