In the final model year, BMW made numerous improvements to the sedan in order to address criticism that had been levelled relating to lack of space and the hard front suspension. Design modifications significantly strengthened the all-steel body and the interior was lengthened by 20 cm. The greater length was primarily beneficial for passengers seated in the rear. The newly developed front swing axle held out the promise of better road holding and increased driving safety. However, contrary to expectations, the softer cushioning resulted in reduced overall stability and directional stability, leading to strident negative reviews from the trade press.
