How does Audi A5 engine compare to other cars in its class?

I've heard mixed reviews about the Audi A5 engine but I'm considering it as a potential purchase. Can anyone provide insight on how it stacks up against other engines in its class in terms of performance and reliability?

Audi A5's engine has a great balance of power and fuel efficiency. I've had mine for 3 years now and it's still running strong.

In terms of performance, the Audi A5's engine is definitely one of the best in its class. However, it is known to have some reliability issues after a few years of use.

I've driven several cars in this class and the Audi A5's engine is by far the most smooth and responsive.
