The All new Audi RS5 TDI concept was released with several shots, and promises to deliver its production version with an Electirc Turbocharger as opposed to the current Biturbo V6 version, which will work via an immediate boost in power unlike an ordinary Turbocharger that needs to wait for exhaust gasses.

The Audi RS5 TDI will feature a 48 Volt electrical system, which is already in production vehicles in the Audi lineup, says Prof. Dr. Ulrich Hackenberg.

The Car will features a V6 TDI with three turbo, two of which are backed by the electric turbo which spins the compressor wheel to over 70,000rpm resulting in an great surge of power with almost none of the turbo lag.

The Audi RS5 TDI concept will be equipped with a 48-volt power system that is responsible for providing all the energy need to power the electric turbo, utilizing brake recuperation and storing that energy/electricity in the lithium-ion battery onboard.

Now you might be expecting big power figures, but the Audi RS5 TDI relies on tourque with 553 Lb-Ft of it and 385 hp which is less than the current 450hp RS5. But it still manages to sprint from 0-100 in 4 seconds which is a half second faster. The big news here is that it manages 44mpg of diesel (5.3l/100km), as opposed to the current model with 18mpg (13L/100km)

While we think that hybrid technology is pretty cool, we don’t see how three turbos powered by an electric turbo makes any sense.
