A recent report published on the independent Audi website Fourtitude claims the next model RS4 and RS5 (B8-based) will use V8 engines. There has been a lot of speculation about the powerplants for the upcoming über-Audis, with some suggestion of a turbocharged 3.0 V6 being used. However, after speaking with an Audi executive the Fourtitude lads wrote “The RS4 and RS5 will get a high-revving engine like the outgoing RS4. The high-rev applications in the R8 and B7-generation RS4 have impressed Audi’s engine development teams and they wish to continue in that direction with the next-gen of Audi’s hottest models.”
Audi is expected to stick with 4.2 litre displacement used in the previous RS4 and power could be up by as much as 50hp on the 420hp available in the old model. Power will be put to ground through an optional 7-speed S tronic transmission and a revised quattro system. Follow the links below for more detail.
