This matters very little right now, because of how restrictive the ACO's rules are with using KERS as a power boost system (it's automatically activated), and that Audi and Peugeot currently aren't running such a system, as if the diesels have a torque shortage anyways
Also, the Fourtitude article says that the photogs were discouraged by Audi from taking photos directly into the cockpit. That said, there's Audi Sport's own photo of Dumas in the car (which prompted the steering wheel discussion), and there are a few photos into the car showing the wheel and the dashboard, and a brief description of the dash.
I'd expect Audi to release more detailed photos at the LM test weekend or the next round to studio shots.
