An Audi RS3 competed against an Audi RS3 with a particulate filter.

Rumor has it that the GPF implementation in gasoline engines worsens their performance. Carwow’s journalists decided to find out whether this is true or not. They did it in their usual way, through drag racing. Two sports hatchbacks with the same engines and specifications took their spot at the starting line. One of them is Audi RS3 2017 equipped with an ordinary engine, while the other was released in 2020 and has a 2.5-liter TFSI engine with implemented GPF technology.
