It is a car that thrives on long-distance grand touring, where its stability and power come into their own, yet it remains perfectly at home running mundane errands through a congested city centre.
For a performance coupe, the TT RS is surprisingly usable in day-to-day conditions. Its compact footprint makes navigating busy urban centres a breeze, and parking is rarely a source of stress compared to larger performance cars. The 305L boot space is adequate for a weekend getaway, provided one packs efficiently. While the ride can be firm in Sport mode, it is easily moderated for more comfortable daily driving.

Achieving 30 mpg on a steady run is a welcome benefit of the V6 layout, though enthusiastic driving will see that figure plummet. Servicing intervals are well-structured, though the Quattro driveline does require specific attention to remain in peak condition.
