Fun and sporty, the A3 was miniaturized to 1:32 scale for an engaging slot car experience. Rather than old school pistol-grip controllers, each Audi car featured integrated pinhole cameras that streamed in real-time to iPads that were operated by players. Tipping the tablet forward and back controlled the throttle with ease. Onlookers tracked races via displays that cut between the action from cameras triggered by IR sensors as the cars sped past. The custom-designed track, housed inside a custom-designed glass enclosure, contemporized a piece of nostalgia.
