THE BREAKDOWN The RS5 will be Audi's first plug-in hybrid RS model. Aside from an entry-level EV, the next-generation Q7, and the first-ever Q9, Ingolstadt will spice up its lineup with a long-awaited RS model. The next-generation model will be Audi Sport’s first plug-in hybrid. Motor1's Take: Some purists will scoff at the idea of a plug-in hybrid RS, but that’s how the cookie crumbles with Euro 7 looming. Hopefully, the same will be true for the RS6, although that V8 is also likely to be part of a plug-in hybrid setup.
