Why does the Audi A3 use direct fuel injection?

I've noticed that many newer cars, including the Audi A3, use direct fuel injection. What benefits does this technology provide and why has it become so popular in recent years?

Direct fuel injection is a more efficient way to deliver fuel to the engine, resulting in better performance and fuel economy. It also allows for more precise control over the fuel-air mixture, leading to cleaner emissions. It has become popular due to stricter emission regulations and the desire for more powerful and efficient engines.
