That has got to be one of the best Audi concepts and if it does get produced, no doubt the best looking Audi imo.

everything flows, smooth design - love it :p

Found out some new really innovative features to the A7 3.0tdi

When the engine is started from Cold part of the coolant is diverted so that the engine warms up quicker. Sounds like a good idea.

"As engineers began to develop the BlueTDI, their first goal was to achieve further overall combustion optimization in the engine. The world premiere of such an innovation is being celebrated in the BlueTDI - the combustion chamber sensor. Integrated in the glow plug, the sensor continuously measures pressure conditions in the cylinder and reports the data to engine management.

This enables perfect control of injection and combustion in each cylinder; it is even possible to compensate for fluctuating qualities of fuel. Ideal combustion helps to reduce raw emissions. It also optimizes smooth running and noise behavior.

The intensively refined common rail injection system serves the same purposes. With a newly designed pump, the system builds up 2,000 bar of pressure - also an innovation. The piezo injectors have been significantly modified too. Their smaller eight-hole nozzles inject miniscule spray volumes into the combustion chambers. This, together with the higher pressure combine to produce an injection that is even more precise and dynamic - detailed work that as a whole has resulted in one of the most economical and cleanest six-cylinder diesel engines in the world.
