Audi points to more powerful versions of the RS6 and RS7: Both feature a 4.0-liter V8 with two turbochargers that delivers 592 hp (441 kW / 600 hp) and 800 Nm (590 lb-ft) of torque. Thanks to an eight-speed automatic transmission and quattro all-wheel drive, the cars can rocket from 0 to 100 km / h in just 3.6 seconds.
These are some pretty impressive numbers, but in the future more powerful variants are expected. This should not be too surprising as the predecessor generations RS6 and RS7 were offered in the performance version. They had a 4.0-liter V8 with two turbochargers, which developed up to 597 (445 kW / 605 hp) and 553 lb-ft (750 Nm) of torque.
While the company was not ready to talk about new variants, the people responsible at Audi Sport gave a few pointers in an interview Road & Track, Among them was Oliver Hoffman, who confirmed that “we will have plug-in hybrid technology in our RS portfolio”. He suggested that they would be a step above the basic RS models, and this strongly implies that plug-in hybrid powertrains are used in the new performance variants.
There were rumors of plug-in hybrid versions of the RS6 and RS7 and they are expected to use the same twin-turbo V8 as the standard model. However, you could also borrow some components of the A7 Sportback 55 TFSI e, namely its 14.1 kWh lithium-ion battery and 141 hp (105 kW / 143 hp) electric motor.
In related news, Audi sports officials confirmed plans for an RS Q8 and said it will be unveiled later this year. This probably means it will be unveiled at the Los Angeles Auto Show along with the e-tron Sportback.
