More powerful Audi TT still in the works?

Spy photographer Hans G. Lehman caught a prototype Audi TT that insiders say might be a high-performance variant of the new coupe. Dubbed the "TT-S," the vehicle is said to have the 2.0-liter 4-cylinder engine from the new Audi S3. Recently, there has been speculation that a more powerful version of the TT will not be offered. The car pictured appears very similar to the recently-introduced TT S-Line package, but has exhaust pipes on either side of the rear apron, rather than on one side as with the S-Line kit.
