The new-generation Audi RS4 has been spied testing in Avant form at the Nürburgring, prior to going on sale later this year.
The S4 was revealed at the Geneva motor show in March, so we expect this generation of RS4 to follow shortly, in both Avant and saloon variants.
Although a previously spied prototype is badged as an S4, the extended wheelarches gave it away as an RS. This version is clearly identifiable as the RS4, however, because of its large twin exhausts and aggressive front-end styling.
Powering the new model will be a tweaked version of the 349bhp turbocharged V6 that features in the S4. An output of around 500bhp is expected, meaning the new RS4 will be competitive against its main rivals, the 503bhp Mercedes-AMG C63 S and the 425bhp BMW M3. By comparison, the current RS4 features a naturally aspirated 4.2-litre V8 engine with 444bhp.
