Development on the car had begun in earnest, some ten months prior to its unveiling. Upon launch, designer Gustav Brunner said; "The TF103 was a highly competitive package. Unfortunately, we couldn't get all of the performance out of it. Theoretically, the TF104 is an evolutionary step up from the TF103, but in fact, the TF104 shares not a single part that we used with the TF103. We improved every single inch of the chassis, and redesigned every important internal component. We achieved a great leap ahead aerodynamically, made the car lighter overall, and increased the rigidity of the chassis".
