The transmission is monitored and regulated by Audi's "Dynamic Regulating Programme" (DRP),[REF] which tracks the driver's inputs (from how the driver applies the throttle pedal),[REF] driving conditions, and engine load - to compute the optimal gear ratio for fuel efficiency or maximum performance, as mandated by the user [REF].
Early versions offered six ratios;[REF] in 2004, this was increased to seven, while new Audi models now have Multitronic transmission with eight ratios.
