Audi has already shown us two concept versions of its V12-powered R8 diesel supercar but whether this means the concept is headed for production is still up in the air. Some officials within Audi claim there is a chance the car will be built, but at the same time there have also been several denials of the possibility of production.

The latest twist in the story is that a final decision will be made by the middle of the year after all considerations concerning the economy and market forces are taken into account. The information comes from Audi spokesman Josef Schlossmacher, who told Automotive News Europe the car could be in showrooms within two years if given the green light.

One of the biggest hurdles the R8 V12 TDI faces is the fact that Audi has plans to launch a new V10 RS-R8 flagship. One possible solution would be to use a smaller 4.2L V8 TDI engine instead of the V12. However, considering the niche status of both cars it doesn’t make sense for Audi to separately develop and launch two different range-topping R8 models. Another stumbling block for a diesel R8 are tough new emissions standards planned for both the U.S. and Europe in the near future, factors that will influence the final decision on the R8 V12 TDI due this summer.
