Main candidate is the RS4 which may make it stateside by next year. A more favorable euro-dollar exchange rate and converging emissions regulations are helping the business case for taking low-volume RS models to North America.

Audi will be bringing more RS models to the U.S. market, the German automaker has confirmed.

At the recent Audi Forum at the company's headquarters in Ingolstadt, in the German state of Bavaria, Stephan Reil, head of development for Audi Quattro, cited the more favorable euro-dollar exchange rate as well as converging emissions regulations as factors helping the business case for taking low-volume RS models stateside.

Audi only recently announced that the TT-RS was headed for the U.S. market and the premium automaker has delayed the introduction of the RS5 model until 2012 when the entire A5 range gets a make-over.

Out of the running for an RS-variant are Audi's range of SUVs as well as the A8 which Reil says is too big.

So which model(s) is Reil talking about?

Mainly the RS4 which he says will arrive "maybe next year."
