Audi rules out faster TT

To leave enough room in the line-up for the muscular R8, exclusively revealed in this week's mag, Auto Express can also reveal that the TT S line is as hot as the new coupé is likely to get - because bosses have no plans for a high-performance version.

The S line upgrades are purely cosmetic. They include handsome alloys inspired by the rims on the RS4, while revised bumpers with a carbon fibre chin spoiler and rear valance also appear. Prices have yet to be announced.
