Audi offers a generous selection to customers looking for a refined, coupe-like luxury car. There are three distinct body styles to choose from including coupe, cabriolet and five-door Sportback, plus a choice of three engines. The base 248-horspower turbo-four gives way to a turbocharged V6 rated at 349 horsepower in the sportier S5, while a 444-horsepower, twin-turbo 2.9-litre V6 motivates the RS 5. If you’re a performance enthusiast, that last one is a must.
