Because 600 horsepower isn't enough for some people.
The Audi RS6 Avant has been forbidden fruit to US customers for a very long time, but that changed last month when Audi announced the performance wagon is finally coming to America. It was joined by the new RS7 Sportback at Frankfurt, and both look absolutely stunning in the metal. With nearly 600 horsepower on tap, the RS6 and RS7 aren't exactly underpowered, but Audi has hinted that more powerful versions are in development.
During a preview event at the Frankfurt Auto Show, Audi Sport bosses said how the performance brand will embrace electrification in future models, suggesting that there will be hot plug-in hybrid variants of the RS6 and RS7.
"Six-hundred is high, but if you say, 'I would like to have a Competition [or] Performance model,' at the end if the market is there, you can afford it, then you can make it," Victor Underberg, Audi Sport's head of technical development, told Road and Track when asked if electric assistance could increase the output to over 600 hp.
Audi Sport co-managing director Oliver Hoffman added that future RS models will get the plug-in treatment, but didn't specify which models. However, it seems likely that the RS6 and RS7 will get plug-in-hybrid variants.
In the past, Audi has offered performance packages for the RS6 and RS7, but adding hybrid assistance will make them considerably more powerful. There have already been rumors that Audi is preparing to unleash a 700-hp hybrid version of the RS7, so it would make sense for the RS6 to get the same treatment since it shares the same setup.
In the meantime, the stock Audi RS6 Avant is powered by a 4.0-liter twin-turbocharged V8 with mild-hybrid assist producing 591 horsepower and 590 lb-ft of torque. This setup enables the speedy wagon to sprint from 0-62 mph in 3.6 seconds and hit a limited top speed. The Audi RS7 Sportback adopts the same 591-hp V8 and has identical performance specs to its RS6 sibling.
