Audi RS4 and RS5 to keep V8s
According to Fourtitude, the 4.2-liter FSI V8 will soldier on in the RS4, and will also find a home in the RS5, which is currently undergoing testing both in Germany and the U.S. While a boost in output wasn't divulged, engineers will supposedly keep displacement the same, while decreasing frictional losses and possibly incorporating a new version of Audi's Valvelift system. If all goes according to plan, expect at least 450 hp from the direct-injected 4.2 and don't be surprised to find the tweaked V8 in the revised R8 around the same time.
