Standard equipment includes power windows and door locks, automatic speed control, leather - wrapped steering wheel, stereo radio and tapedeck with equalizer, illuminated visor vanity mirrors, 8,000 - rpm tachometer, 150 - mph (240 - kmh) speedometer, and gauges that

Compared with the last - gen TT RS, the 2.5 - liter
turbo five in the new - for - 2018 model breathes better (thanks to new cylinder head with variable valve lift and duration timing on the exhaust cam), weighs nearly 60 pounds less (an aluminum block, magnesium upper sump, and other fat - reducing
measures), and makes considerably more power, the byproduct of new port fuel injection and an increase in
boost pressure from 18.1 to 19.6 psi.
