At the 2008 North American International Auto Show (NAIAS) in Detroit, Audi released the first Audi «S» model of the TT range – the Audi TTS quattro, with a heavily revised 2.0 TFSI engine. The cylinder block, cylinder head, and the fuel injectors have all been modified from the base 2.0 TFSI engine (ID: CDL). Together with other modifications, this engine produces a DIN-rated motive power output of 200 kilowatts (272 PS; 268 bhp), and generates a torque turning force of 350 newton metres (258 lbf·ft) from 2,500 to 5,000 rpm. The suspension is lowered by 10 millimetres (0.4 in) over the standard models, and includes «Audi Magnetic Ride» as standard and a new two-stage sports-biased Electronic Stability Programme (ESP). Radially ventilated front disc brakes are clamped by a single-piston gloss black caliper emblazened with a bold TTS logo, and a lap timer is prominent in the centre of the instrument cluster. 9Jx18″ ‘5-parallel-spoke’ design alloy roadwheels are standard, with 245/40 ZR18 high-performance tires. 19″ ‘5-spoke star’ wheels and tires are optional. The exterior: with redesigned front, with larger air intakes, redesigned rear bumper, side sill extensions, and four exhaust tailpipes.
