The Borgward Hansa 2400 was an executive six-cylinder saloon (E-segment) presented in 1951, and manufactured by the Bremen based auto-manufacturer Carl F. W. Borgward GmbH from 1952 to 1959.

The Hansa 2400 commenced production in 1952 as a large fastback saloon, its profile reminiscent of the recently introduced Hudson Super Wasp. A year later a longer-wheelbase notchback limousine version appeared.

The engine was a six-cylinder engine of 2337 cc with a claimed power output of 82 bhp  and a top speed of 150 km/h.

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. It was produced from 1954 to 1962.

11,150 Isabellas were produced in 1954, an early indicator that commercially this would be the most successful Borgward ever. Unfortunately, early models were afflicted by teething troubles. 

A road test at launch reported a maximum speed of 130 km/h. 

Borgward had many unsold Isabellas when it went bankrupt in 1961. By the end, 202,862 Isabellas had rolled off the Borgward production line.

The Borgward P100 is a large four-door sedan first presented in September 1959 at the Frankfurt Motor Show, and produced between January 1960 and July 1961.

The straight-6 2240 cc engine derived from that fitted in earlier Borgward six-cylinder sedans, of which the most recent had been the Borgward Hansa 2400 Pullman. Performance figures included a power output of 100 bhp and a maximum speed of around 161 km/h.

The design featured the ponton, three-box design pioneered by Borgward in 1949, but now filled out to the relatively angular corners, reminiscent of the style being popularised by Pininfarina.
