What’s it like?
Loud. Or at least it is with the ‘S’ button depressed. This changes the throttle map and opens the exhaust baffles to tell the world that there’s something more potent than a four-pot lurking under the bonnet. The five-cylinder arrangement gives a characteristic off-beat thrum under full throttle and the occasional pop and splutter on downchanges.
The surprise here is quite how boisterous the engine is for the usually super smooth Audi brand. It can get intrusively bassy when loaded from low revs, but switching ‘S’ off, trims this back to an acceptable level.
Sounding the part is one thing, but the better news is that the TT RS has the performance to match: 0-62mph takes just 4.6sec, and unrestricted it will run to 174mph. To say it has a strong mid-range is a bit of an understatement, with that peak torque available from 1600rpm all the way to 5300rpm. But equally it is not shy of revving right to the redline.
