UPDATE: It turns out this is the separate F12 e Sport prototype, which Audi researchers have been using to develop a modular electric car platform. It is not the production R8 e-tron.

Audi has already told us about the motorsport-inspired digital rear view mirror it plans to install in its upcoming R8 e-tron, but now we have details of two other digital displays that may appear in the electric supercar.

A prototype for the R8 e-tron on display at a recent event in Germany shows a fully digital instrument panel located behind the steering wheel, with the normal tachometer being replaced by a power meter.

Though this isn’t that out of the ordinary (a number of luxury and performance cars are switching to customizable digital instrument panels), also fitted to this prototype is a large digital center stack with touch capability, which is something relatively new, especially so for Audi, an automaker known for building cars with intuitive and tactile controls.

As this latest video, via Plug-In Cars, reveals, the R8 e-tron’s new digital center stack integrates all the controls for the car, such as for the climate control, audio and most likely everything else that will be adjustable in the R8 e-tron. It appears there are no other buttons located on the dash.

As electric car fans will note, the setup is very similar to that found in the Tesla Model S, which also uses a large digital touch-screen for its center stack.

We should know soon just what Audi has planned for its R8 e-tron, as the electric supercar is expected to make its debut in production trim at this week’s 2012 Paris Auto Show, before going on sale by the end of the year.

It will produce a peak 308 horsepower and 604 pound-feet of torque, and be capable of going from 0-60 mph in just 4.6 seconds.

The cars will be produced in a small facility at Audi’s main plant in Neckarsulm, in the south of Germany, and production will be limited, meaning they will be pricey, with some suggesting they will be the most expensive model in Audi's portfolio.

Stay tuned for an update.
