The previous R32 model was a well proven build, but the R32 wasn't without faults and suffered with uplift and balance issues. Along with that, Nissan was, as other Japanese companies were, under strict restrictions on power gains. So, to combat all those areas, Nissan created the sophisticated strength Programme. Nissan increased the width by about one inch on the R33 to the R32 and made it about 4 inches longer. This gave the R33 a longer wheelbase overall and lower stance mixed with new technology now from the computer aerodynamic age. Each line on the R33 was intended to give the car ultimate aerodynamics with wider gaps in the bumper and angles of air movement which allowed better cooling, in addition to the fuel tank lifted; the battery moved to the trunk. Rigidity points were added mixed with improvements on the Attessa and Hicas all now offered the R33 with the best aerodynamics, balance, and handling. Nissan engineers also found other ways to reduce weight, even by a few grams.
