<P> As an additional package a standard Audi TT can be bought from factory with a special body kit upgrade to make it look like the Audi TT - RS version . The upgrade includes a fixed rear spoiler, and Alcantara / leather sports seats (Silk Nappa, Fine Nappa leather optional). </P> <P> 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 of 350 newton metres (258 lbf ⋅ ft) from 2,500 to 5,000 rpm . </P> <P> It was available with a choice of either a six - speed close - ratio manual transmission, or a six - speed' S tronic' transmission . In the United States, the S tronic gearbox was the only available transmission . Like all Audi "S" models, it was only available with quattro four - wheel drive as standard . </P> <P> The suspension was 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 emblazoned with a bold TTS logo, and a lap timer is prominent in the centre of the instrument cluster . 9Jx18"' 5 - parallel - spoke' design alloy wheels are standard, with 245 / 40 ZR18 high - performance tyres . 19"' 5 - spoke star' wheels and tyres are optional . The exterior has some changes over the standard model--with a TTS body styling: with redesigned front, with larger air intakes, redesigned rear bumper, side sill extensions, and four exhaust tailpipes . </P>
