It’s hard to believe but the mighty RS nameplate is 25 years old. Since 1994, Audi has been adding horsepower and massive gobs of performance to its vehicles, starting with the RS 2.

Co-developed by Porsche, the car featured Audi’s signature turbocharged 5-cylinder engine. With its unique firing order, the wagon didn’t just look wild, it sounded it, too.

Back then, though, Audi only produced one RS model at a time. But in the late aughts, they realized that more RSs meant they could spread more joy to the world. As of right now, Audi Sport has made 25 RS models.

In 2017 alone, Audi released the RS 3 Sedan, the RS 5 Coupe, and the RS 4 Avant. This year, they’re promising 6 new RSs, including two completely new ones that have never been RS’d before.

Although Audi Sport wants to keep that a secret until its ready to reveal them, a look at recent spy photographs would suggest that an RS Q8 is on its way and that an RS Q5 might join it.
