The second last paragraph reads:

"Audi remains tight-lipped on further developments for its RS lineup, but genior Ingolstadt officials do not rule out plans for even more radical versions of the S3, S6 and SS - the latter of which is said to run a twin-turbocharged 4.2-liter V-8."

I think it was a typo....it should be S8
