One of Audi’s next three RS model, the RS6 will be unveiled this fall at Frankfurt Motor Show. As we all know enough is never enough when we talk about cars. This is why, the 435 hp of the normal A6 didn’t pleased Audi, and they decided to upgrade the power into an RS version.

If you have seen spy shots of the model, you noticed that there are no big difference between the RS6 and the A6. The front is unchanged, but the lower edge of the front airdam is a little more robust than that of the S6 and the air intakes no longer feature a strip of LED lights across the top.

From one of the sportiest Audi’s, the RS4, the new model will get the double-spoke wheels. In the back you will see another design element exclusive to Audi's ultrahigh-performance RS models: a pair of oval exhausts tips.

The RS6 will be powered by a turbo charged version of the 5.2-liter V10 used in the S6 that will take to a power improvement between 50 and 100 horsepower. This will help the RS6 to easily compete with BMW M5 and Mercedes E63 AMG.

After it’s unveiling in September, the RS6 will come on the US market at the end of this year.
