It wasn’t until July last year that the new line-up made its way to Australia, however, and a confirmed mid-2017 launch for this new hero pair will mean a similar wait for those with a preference for the RennSport pedigree.
As with the latest RS3 Sportback, the new TT RS is driven by an uprated version of Audi’s beloved 2.5-litre five-cylinder turbocharged petrol engine.
But, while that little monster gained an already impressive boost from 250kW and 450Nm to a new 270kW and 465Nm, the new TT RS models are packing 294kW and 480Nm - a leap of 44kW and 17Nm beyond the numbers of their predecessors.
And while the previous TT RS coupe claimed a likewise thrilling 0-100km/h time of 4.1 seconds, Audi says the new coupe will hit the ton in 3.7 seconds, with the roadster a hair behind on 3.9 seconds.
By comparison, the new $354,900 R8 V10, with its 397kW 5.2-litre heart, lists a 0-100km/h time of 3.5 seconds.
Both TT RS bodies are fitted with a seven-speed S tronic auto transmission exclusively, once again sending power to the familiar quattro all-wheel drive system.
Apart from their huge power, tweaks for the TT RS models include a 10mm lower ride, optional RS sports suspension magnetic ride adaptive dampers controlled via the Audi Drive Select system, 19-inch alloy wheels and optional 20-inch forged lightweight wheels.
There’s also the familiar RS aero and styling, including specific bumpers at both ends, new skirts and a rear wing.
The 2017 TT RS also marks the first appearance of Matrix OLED lighting technology at the rear of any Audi model.
The new TT RS models will make their European-market debut in the coming months, with an Australian launch set for the middle of next year. Local pricing and equipment will be confirmed closer to then.
