8-speed Tiptronic S in the Panamera Diesel reduces fuel consumption and improves comfort. How? With a particularly wide gear ratio spread. The relatively low engine speeds in the upper gears reduce noise levels in the interior, especially on the motorway. 8-speed Tiptronic S shifts automatically and adapts to your driving style. Of course, you can still change gear manually at the gear selector itself or using the two ergonomic gearshift switches on the steering wheel.
