Compared to its predecessor he has become rounder. This also applies to the windows and leads to slightly more interior space. Unfortunately also increases the belt line, what the car in the interior lets appear not necessarily friendlier. Even the slightly harder suspension raises it off the Kadett A, makes it clearly more uncomfortable, but also with more payload capacity. In this respect, the Kadett belongs with its comparatively enormous trunk of the best in its class. A level which was never reached again.
The revision after two years is doing well its undercarriage and brakes. From the outside, the variants are hardly to differ. Interesting is the name of the rear axle chosen by Opel, the with the term 'central joint' conceals a little, that it is a slightly corrected leaf spring rigid axle and thus about the simplest possible suspension for driven rear axles. The guide will be a bit more accurate by a support pipe about the rear part of the cardan shaft. In 1967, it is replaced by a coil spring rigid axle and now delivers pretty good results.
There is the Cadet B in a plentitude of options including L-and Coupe version. It is, however, remained in the memory actually only in the rally version. Later there is even the limousine in rally look. At the time (1970) then other engines are also available for the Kadett. It has a particularly long construction time for Opel and is well one of the most successful models in the history of the company.
