The current C6 RS6 was discontinued in 2010 and there was no hints of a replacement in development.

It is great to see that Audi have not forgot its Bi-Turbo Quattro’s in this latest prototype to sneak its way from Neckarsulm home of the RS models up to the winter wonderland in northern Sweden.

This car is in mule form on first looks, like a current A6 based Avant sporting A8 wheels.

But on closure inspection we notice the aggressive front bumper leading its way back through to the Ceramic Disks front and back, this is no other than an upcoming RS6 Production prototype.

We are expecting the car to be powered by a V8 Bi-Turbo 4.0 liter engine which is currently in use on the New Bentley Continental GT and the current S8.

But this car will be going head to head with the likes of the BMW M5 & the new AMG C63 so expect BHP to be around 580hp mated to a revised Bosch ESP and EBD safety system and the usual Quattro AWD with DRC.

Enjoy the remarkably uncamouflaged mule and keep an eye out for the production prototypes around april this year.
