Transmissions
multitronic
A continuously variable transmission available on front-wheel-
drive models, multitronic operates across an exceptionally
wide range of gear ratios thanks to its steel link-plate chain
construction. This leads to superb driving comfort, as well as
smooth acceleration over the entire range of engine speeds. It
also intelligently monitors gradient, road conditions and the
way you use the accelerator pedal for increased fuel economy,
while offering eight simulated gear ratios so you can adopt the
driving style of a manual.
tiptronic
The automatic 6-speed tiptronic transmission is available on A4
models with quattro® permanent all-wheel-drive. The technology
incorporates the efficient Dynamic Shift Programme, which
enables crisp, fast gear changes, as well as reduced weight
and optimised gear-shifting. In the ‘D’ (Drive) and ‘S’ (Sport)
programmes, tiptronic responds efficiently to every driver input,
helping to prevent unwanted gear changes. But you can also
override automatic mode by moving the gear lever into a tiptronic
shift-gate, enabling a sportier driving style.
S tronic
Driving is all about thinking ahead, which is just what the
S tronic dual-clutch transmission does in the Audi A4. It
works almost as two separate systems, one engaging the
odd-numbered and the other the even-numbered gears.
So when you’re accelerating in second, it has third gear waiting
for you. And once you make the switch, it’s already thinking
about fourth. With two clutches working together, you can
change gears almost instantly while experiencing smooth,
uninterrupted power.
