Audi Brings Two New US-Market RS Cars To NYC Auto Show: 400 HP TT RS And RS 3 Sedan – Forbes
Audi will present two RS models for the U.S. market at the New York auto show next week. Both TT RS and RS 3 sedan are powered by an all-new 400 horsepower 2.5-liter 5-cylinder turbo. As is customary with the current generation of Wunder Turbos, maximum torque of 354 lb.-ft. is available over a wide spread, between 1700 and 5850 rpm. Both cars should be very easy to exploit. Both vehicles have a 7-speed dual-clutch transmission that offers the sort of launch control function one finds in all VW Group performance vehicles, from Porsches and Lamborghinis to Audis.
Quattro all-wheel drive is standard in both cars, and mandatory to put so much power down. An electrohydraulic multi-plate clutch can send nearly 100 percent of available torque to the rear wheels, and can constantly adjust distribution of torque to help maximize grip and control.
Also following patterns of the VW Group, including even VW Golf R, there are four distinct drive modes: comfort, auto, dynamic and individual. Individual allows a mix-and match of powertrain and suspension calibrations. Each of the various modes allows the driver to change shift points, steering weight and action, throttle response and, if equipped with the optional magneto-rheological dampers, suspension damping. In cars of this sort, magneto-rheological dampers seem as mandatory as quattro—this is not the place to get tight with cash. Magneto-rheologicals enhance ride quality on a bumpy highway, and help on a mountain road.
Optional carbon-ceramic front disc brakes are expensive to buy and maintain, and are only a benefit to extremely aggressive drivers because they only perform to optimum when good and hot. Both cars have standard 8-piston monobloc brake calipers and metal rotors—that’s a lot of brake. Carbon-ceramic front brake discs are available and are roughly 8 lbs. lighter, which might slightly enhance steering feel and the suspension’s action on turn-in, though with power flowing to the front wheels an RS will not match the steering purity of competing rear-drive cars. When really driven hard, these carbon-ceramic brakes are far less likely to fade, but they are also prone to scratchy noise when cold. When cold, they do not possess the same consistent initial bite that the less exotic metal brakes do.
