Audi, Zac Efron Zac Efron sporting his new Audi S5 May 9, 2011 Check out Zac Efrons sweet Audi S5. All black is a good color for this car. We think the Audi S5 is one of the best coupes on the road. It’s sylish and sexy. If Audi could only bring over the RS5 and make the price around 60k we would have a winner.
