This is Audi’s idea of a TT in the GT3 RS or Superleggera mould: the TT Ultra Quattro concept.
Thanks to a ruthless diet and an uprated 2.0-litre TFSI turbo petrol engine, the all-wheel drive TT Ultra will launch to 62mph in 4.2sec, (1.3sec faster than a regular Audi TTS) and hit 173mph flat out.
Just how light is the Audi TT Ultra?
Exactly 300kg lighter than a standard TTS, at 1111kg. A large part of that saving comes from a modified body structure: a carbon rear end, transmission tunnel and B-pillars all shed kilos, as do magnesium floor and door hinge components.
Carbonfibre is everywhere on the TT Ultra. The bonnet is made from the black weave, as are the side skirts, interior trim panels, and the bracing strut across the rear seats. Brakes are of course carbon ceramic, and even the wheel hubs use carbonfibre, mated to aluminium spokes.
