A recent refresh aims to keep the sporty coupé in the limelight, and we want to find out which model best backs up style with substance. To do so, we test the £36,150 TT 2.0 TFSI quattro S line S Tronic, complete with four-wheel drive, against the more practical and powerful Scirocco R 2.0 TSI 280 DSG range-topper, which comes in at £34,035.
