Styling? It depends on what you are looking for, but the TT RS is the most aggressive of the two. In fact, it looks even more badass than the RS6. There's a gaping grille at the front, huge oval exhausts at the back and a tiny cockpit in the middle. But even though I'm an Audi fan, the 718 Cayman S strikes me as a more beautiful machine. "Perfect" is a word that could be used to describe the proportions.
The interior department favors Audi, as always. The RS model has the same de-cluttered dash and Virtual Cockpit we've already seen. You can also order carbon fiber trim for the doors and dash, which is a plus. The steering wheel arguably looks better too, thanks to the bright red button copied from the R8.
In a straight line, the TT RS will keep up with some old supercars. The coupe version takes just 3.7 seconds to reach 100 km/h while the roadster needs 0.2 seconds more.
Meanwhile, the Cayman S with PDK and Chrono requires 4.2 of your seconds to reach 100 km/h, partly because it features a 370 PS 2.5-liter engine. Of course, even though they have the same displacement, everything else about the engines of these rivals is different. The TT has a 5-cylinder sitting longitudinally at the front and sending power to all four wheels. Meanwhile, Porsche has a brand-new 4-cylinder boxer unit with a twin-scroll turbocharger delivering the goods at the back.
