Beauty, performance, & the V8 sound makes the s5 as class of its own. I have owned a BMW, Acura, Infinity and Land Rover, I have to say that this Audi S5 is the best car I have ever owned! The engineering, performance, and technology is superior. As well it is a blast to drive. 0–60 mph (0–97 km/h) time is around 4.4 seconds (coupé) & 4.5 seconds (sportback), with a limited top speed of 155 mph (249 km/h).
