Why is the 2021 Audi A4's engine considered to be one of the best in its class?

I've heard a lot of great things about the 2021 Audi A4's engine, but I'm not sure what makes it stand out from its competitors. Can someone provide an explanation?

The 2021 Audi A4 boasts a powerful 2.0L turbocharged 4-cylinder engine, which is well-known for its smooth acceleration and impressive fuel efficiency. It's also equipped with a 12V mild hybrid system, providing an extra boost of power when needed. From my personal experience, this engine delivers an exhilarating driving experience while still being practical for daily use.

The key to the 2021 Audi A4's exceptional engine performance lies in its advanced engineering and cutting-edge technology. Its highly efficient TFSI (Turbo Fuel Stratified Injection) system delivers precise fuel injection for optimal power and fuel economy. As a bonus, the engine also produces a sporty and satisfying sound that will surely leave a lasting impression.
