Audi is taking aim at the new Porsche Boxster and its yet-to-be-revealed sister model, the upcoming second-generation Cayman, with a spectacular 174-mph version of the TT RS, pictured here officially for the first time. Called the TT RS plus, the powered-up coupe and roadster pairing is set to join what is shaping up as a formidable display of new Audi models--including the third-generation A3 and the RS4 Avant--at the Geneva motor show in early March. The centerpiece of the new range-topping TT is a tuned version of Audi's turbocharged 2.5-liter, five-cylinder direct-injection gasoline engine as used by the go-fast TT RS, the RS3 Sportback and the limited-production A1 quattro.
