The 1999 Audi R8R is a difficult car to analyze.  Technically, there were three different variants;  the original concept car that was shown late '98 and took on the bulk of the early testing, the Sebring variant, and the Le Mans car.  Also consider that at the same time Audi was developing the R8C LMGTP.  It should have been clear from early on that Audi was very serious about their Le Mans effort if just slightly unsure of how to focus their energy.
