"The work we do between the end of one season and the start of the next is absolutely critical," he says, speaking v-e-r-y s-l-o-w-l-y, "because the design of the diffuser and main body parts is frozen at the start of the year. DTM is very limited compared to F1, so we have to examine the regulations very carefully to find the areas of potential. I'll give you an example. We have scope for development in the area between the ground and 275mm above the ground, which is roughly where the doors stop. In other words, we can work on the underbody and the floor..."
Most of the focus, then, is on aero and air flow. Mühlmeier talks about Audi's ‘closed loop' process that sees the CFD boffins identify new approaches, before trying them out on wind-tunnel models. After that, the resulting data is fed back to the boffins, who then feed it back into the system and start all over again. Imagine all those algorithms.
