High-performance station wagons are no strangers to Audi, with the company currently testing the Avant version of the 2019 S6.

The fifth generation of the company’s executive sedan is at the final stages of development, with Audi expected to reveal the new A6 at the upcoming Geneva Motor Show.

Those lusting after the more powerful S6 version however will have to wait until 2019. The sportiest A6 this side of an RS model will follow the downsize trend, ditching the 4.0-liter V8 for the sake of a twin-turbo 2.9-liter V6.

It’s essentially the engine used by the Porsche Panamera and, of course, the Audi RS4 and RS5 models, but the latest reports suggest a power figure of more than 450hp. If true, this will make the 2019 S6 more powerful than the original RS6 and make it capable of running sub-4 seconds for the 0-62mph procedure.

On the outside, the next S6 will be distinguished by a more aggressive body kit featuring larger air inlets and sharper edges around the bumpers, alongside with bigger wheels and brakes. A quad-exhaust setup will also be there.

The cabin will follow the same recipe with the A7 and the A8, meaning a tech-heavy dashboard that features a dual-touchscreen setup for the infotainment and climate controls, along with the spicier S touches, meaning sportier seats, a flat-bottom steering wheels and shiny trim bits.

All this performance and technology might lead some people into thinking why would someone ever need an RS6. Set to launch in 2020, the mighty RS6 is reportedly going to borrow the crazy 671hp plug-in hybrid powertrain of the Porsche Panamera Turbo S E-Hybrid in order to show the BMW M5 who’s the real speed king.
