How do the Audi A4's fuel economy and engine performance compare to other luxury sedans?

I'm considering purchasing a new luxury sedan and want to make sure the Audi A4 has good fuel economy and engine performance. I don't want to sacrifice one for the other. Can anyone provide insights and comparisons to other similar vehicles?

The Audi A4's fuel economy is on par with other luxury sedans in its class, averaging around 25 mpg city and 34 mpg highway. However, in terms of engine performance, the A4 stands out with its standard turbocharged 2.0-liter four-cylinder engine delivering 248 horsepower. This gives it a better power-to-weight ratio than its competitors, making it a top performer in its class.
