The tiptronic transmission system is a form of automatic transmission available on selected Audi models with quattro permanent all-wheel-drive. The technology converts high-torque engine power into both sporty performance and operating convenience, with crisp, fast gear changes, reduced weight and an optimised gearshift strategy. More spontaneous gear changes are a particular benefit, especially when down-shifting. Both in the ‘D’ (Drive) and ‘S’ (Sport) programme, the advanced electronics used in tiptronic respond efficiently to every driver input, helping to prevent unwanted upshifts when cornering.
