Audi S4 Avant spy shots

The piping-hot Audi RS4 may not be destined for consumption here in the United States, but its little brother, the S4, will continue to live on in America. Our spy photographers recently spotted this S4 prototype – in delicious Avant flavor – testing on the Nürburgring, showing off a newly facelifted front end.

Much like the A6 and A7, the revised S4 will wear Audi's reshaped grille with slanted upper corners – a design element that will also trickle down to the base A4 and the A5. Additionally, it appears that the front bumper has been tweaked, with larger lower air intakes that are reminiscent of what we see on the smaller TTS. Our spies also suggest that the S4's taillamps will receive a once-over, looking more akin to what's currently used on the A6/A7.

Mum's the word on powertrain upgrades, but we expect that Audi has a few tricks up its sleeve to keep the S4's performance prowess in check. Some minor tweaks to the car's cabin will likely be in store, as well. Look for the facelifted S4 to debut at the Frankfurt Motor Show this September.
