Trademark Audi TT coupe and roadster set to undergo a mid-cycle refresh in 2018

The Audi TT has been a stalwart in the Audi passenger car line-up since its introduction in 1998. Now in its third generation, Audi has been spotted putting the final touches to a mid-life facelift before its official reveal later this year, keeping the model fresh ahead of all-new rivals like the upcoming BMW Z4 and Alpine A110.

The most obvious takeaway from these images are new front and rear bumpers hidden beneath Audi’s usual swirly camouflage. The grille pattern is new, too, more closely emulating the Audi R8 supercar. We suspect that the car in these images is an S-line car, due to the relatively aggressive bumper treatments and sills.

The third-generation TT was originally designed under the two-man design leadership of Wolfgang Egger and Stefan Sielaff. The pair coaxed Audi’s design team towards an angular aesthetic that suffered some criticism for looking both bland and indistinct between model lines.

To rectify this, Audi poached VW designer Marc Lichte to try to reform Audi’s design language in 2014, which is bearing its first fruits in the all-new Audi A8 and A7. This new, more ‘emotional’ design direction should be seen in this updated TT.

Updated front and rear lighting is expected, with LED Matrix technology for the front and OLED rear units expected to be offered for the first time on a TT other than the RS. The current TT’s engine line-up is expected to continue to include a range of turbocharged four-cylinder petrol and diesel options connected to either a manual or S-tronic dual-clutch gearbox.

The Volkswagen Group’s new 1.5-litre EVO engine is also expected to be offered as a new entry point. The TT RS will maintain its lovely 2.5-litre turbocharged five-cylinder engine.
