The Audi RS5 has moved from a twin-turbo V6 to a 630 hp plug-in hybrid powertrain, marking the first electrified RS performance car from Audi Sport. This is important because performance sedans are headed towards hybrid powertrains to comply with emissions regulations and boost power. The RS5 has now merged combustion and electric forces, bringing limited EV range and new tech to the chassis. The refresh is mainly mechanical, as opposed to the last RS5, and signals the future of RS and BMW M models in the electrified performance segment.
