What is the most efficient engine option for an Audi A4?

I am looking for the best engine option for my new Audi A4. Which engine would provide the most power and fuel efficiency?

The 2.0-liter turbocharged four-cylinder engine is the most efficient option for the Audi A4. It provides 201 horsepower and up to 35 mpg on the highway.

If you're looking for a more powerful engine, the 3.0-liter V6 engine with 261 horsepower is a great option. However, it may sacrifice some fuel efficiency for the extra power.

For the best of both worlds, consider the A4 plug-in hybrid. It has a 2.0-liter turbocharged engine paired with an electric motor, providing 362 combined horsepower and up to 27 miles of all-electric range.
