The Audi S5 Cabriolet's fully electronic roof can be lowered with a one-touch function in 15 seconds, even at speeds of up to 31 mph. A powerful engine allows the driver to sprint from 0 to 60 mph in 6 seconds. There's also a suite of infotainment and safety features, including adaptive cruise control with stop-and-go traffic jam assist. In all, a very cool offering from Audi.
