CARS.COM — The redesigned 2018 Audi S5 may not look that different in photos from the outgoing car, but in person, the two-door coupe Audi showed at the 2016 Los Angeles Auto Show has a finer, more chiseled appearance. With the S5, it’s all in details like the intricate headlights and swooping-profile body line that add dimension to the previously simply designed coupe. A lower hood line and lower stance flatten the profile and make the S5 look lower and longer than the outgoing car.
