Why does the Audi A5 have a four-cylinder engine instead of a V6 like other luxury cars?

I noticed that the Audi A5, while still a luxury car, has a four-cylinder engine compared to the V6 engines in other luxury cars like the Mercedes-Benz C-Class. Can someone explain the reasoning behind this decision?

The Audi A5 has a four-cylinder engine because it is lighter and more fuel-efficient, while still delivering the power and performance expected from a luxury car. Additionally, Audi has optimized their engines to provide comparable power to V6 engines, making them a smarter choice in terms of both performance and fuel economy.

Don't let the number of cylinders fool you - the Audi A5's four-cylinder engine is turbocharged and produces 248 horsepower, giving it the same power as V6 engines but with better fuel efficiency. In fact, the A5's engine has been praised for its smooth and quick acceleration. Plus, it helps keep the overall weight of the car down, enhancing its handling and agility.
