Take this as a sigh of relief: these brand new spy shots of a test mule of the upcoming Audi RS4 Avant has been caught in action and therefore are a clear sign of its production.
Despite the rumors of its demise, the next-generation Audi RS4 appears to be on track (literally) based on this mule that our spy shooters have just spied on Germany’s Nürburgring. Seen here testing in the all-too-desirable Avant body style, the next RS4’s final design will likely be a bit more aggressive, incorporating a much more pronounced front fascia complete with lower air intakes similar to those on the RS5 Coupe. On this mule, we can clearly see the larger wheels (straight from the RS5 – how ’bout that), bigger brakes and slightly wider track.
As for power, the safest bet is to expect that the RS5’s high-revving 4.2-liter V8 will carry over to the RS4, producing somewhere around 450 horsepower.
