Gustav Brunner
Designed by John Barnard and Gustav Brunner, the car's design was largely influenced by major regulation changes imposed by the FIA after the dreadful events during the year before: the V12 engine was reduced from 3.5 to 3.0 litre, while new side protection structures were added around the driver's helmet. The aerodynamics were revised with the sides shortened to fit the radiators and other accessories, while front and rear wings were also changed to reduce downforce according to the new regulations. The car also dropped the 'raised nose' design which it had been using for the previous three seasons. The T stood for Transverse, as the gearbox was mounted in this way, improving rear-end weight distribution.
