There's no denying that Audi is planning more variants of the TT and R8, but most of the speculation revolves around fitting both models with high-output engines to produce RS variants. The TT-RS is expected to house a turbocharged, five-cylinder engine making around 350 hp and the R8 will benefit from some form of forced induction, with either a V8 or V10 mill taking the place of the stock 4.2-liter V8 – not to mention the V12 TDI mill. But what about weight reduction?

According to Inside Line, Audi is considering "Sport" variants of both models, a concept that was executed back in 2005 with the introduction of the TT Quattro Sport, which featured a slight bump in power, revised suspension, Recaro thrones and nixed some of the superfluous material inside. Unfortunately, it never made it Stateside.

The new "Sport" versions of each model would use a similar philosophy, and in the case of the R8, that could mean a boost in power to around 500 hp, limiting some of the creature comforts like heated seats, climate control and stereo, and replacing the hood, engine cover, dash, doors and roof with carbon fiber components. And while Inside Line was speculating, they threw on some carbon ceramic brakes for good measure. All told, that could drop the R8's curb weight by some 200 pounds, dropping its 0-60 time into the high three-second range and paying dividends in the handling department. Inside Line expects both models to make it to production next year as 2010 models, although distribution in the U.S. is still an open question.
