The C5 RS6 is also quicker than most sports cars with a simple ECU tune, although a bit heavy for the track in street kit. When the RS6s were racing a few years ago, in race spec they were easily besting all comers in SPEED World Challenge GT including lighter and newer 911s, M3s, CTS-V, etc


And of course the 19080's Sport Quatto was no slouch ;)
