What are the performance specifications of the Audi A5's engine?

I am considering purchasing an Audi A5 and want to understand the specific performance capabilities of its engine. Can anyone provide details on horsepower, torque, and fuel efficiency?

The Audi A5 comes equipped with a standard 2.0-liter turbocharged 4-cylinder engine, providing 248 horsepower and 273 lb-ft of torque. It also boasts an impressive fuel efficiency of 27 mpg in the city and 34 mpg on the highway.

If you're looking for even more power, the Audi S5 features a 3.0-liter V6 engine with 349 horsepower and 369 lb-ft of torque. However, fuel efficiency drops slightly to 20 mpg in the city and 28 mpg on the highway.
