What is FSI direct-injecton???

 

Its a system that Audi has, it basically sprays fuel straight into the cylinder instead of of mixing it with air before it enters the heads and eventually cylinders. I dont know why, but I guess it gives more power, according to Audi

 

This might explain it better than me..click a4 features then FSI
