The guys of Pro-street.dk spotted the German S-line sports car from Ingolstadt lapping the Green Hell. At the Los Angeles Auto Show 2011 will see the introduction of both the Audi S6 and S7. They will use the same 4.0 liter engine. The output is 440hp for the S6 and 470hp for the S7. Power will be channeled to a rear-biased Quattro all-wheel-drive system through Audi’s seven-speed dual-clutch automated manual.
