Audi rolled out an update for the TT coupe and roadster a few months back, revising the sportier TTS models along with 'em. And now it's extended the facelift to the top-of-the-line, performance-focused TT RS as well.

Motivation comes again from Ingolstadt's acclaimed 2.5-liter turbocharged five-cylinder engine, producing the same 400 horsepower and 354 lb-ft of torque as before. But the German automaker has spruced up the styling inside and out to keep the model fresh and at the head of the pack as sister/rival Porsche keeps coming up with more potent versions of its 718 Boxster/Cayman.

That big gaping maw packs more radiators to improve cooling, underscored by a new front splitter, and flanked by new air inlets. The rear wing's been redesigned as well, instantly identifying this as the most hardcore version of Audi's fashion-forward coupe and convertible.

The interior's been spruced up with a new 12.3-inch infotainment display, with optional MMI navigatation system and Bang & Olufsen audio. Otherwise the only visual enhancement to speak of inside the performance-focused cockpit is the red mark at the steering rim's 12 o'clock, helping the driver center the variable steering rack.

Channeled to all four wheels through a seven-speed dual-clutch transmission, those 400 horses rocket the TT RS coupe to 62 in just 3.7 seconds and on to a top speed limited to 155 miles per hour (or derestricted to 174). Removing the speed limiter isn't the only option, though.

Buyers will also be able to opt for the adaptive suspension, choose between eight exterior paint choices (including a new Kyalami Green, Pulse Orange, and Turbo Blue), a host of appearance options, matrix LED lighting (OLED at the back) to replace the standard LED headlights, and (of course) a fixed roof or a fabric one.

No word on delivery date or price for the US, but in Europe the 2019 Audi TT RS will be available in the spring starting from 67,700 Euros for the Coupe and 70,500 Euros for the Roadster.
