Here you go...ours has the 7 speed unit in it.
S tronic (6-speed)
The revolutionary S tronic gearbox combines the agility and responsiveness of a conventional 6-speed manual gearbox with the convenience and smooth, uninterrupted power of an automatic transmission. The technical basis of the S tronic gearbox is the double clutch. This consists of two lubricated plates with hydraulically-regulated contact pressure. One engages the odd-numbered gears, the other the even-numbered, enabling gear-shifts to be made in a fraction of a second, with no disruption to the power flow. Depending on how the mood takes you, you can either allow gear-changes to take place automatically or, for a sportier driving style, operate the S tronic system using the gear lever or steering wheel shift-paddles. The choice is yours.
S tronic (7-speed)
The extra gear, along with a dry-clutch set-up, results in improved fuel economy and lower CO2 emissions. As with the 6-speed S tronic gearbox, this gear system can be operated in fully automatic mode, or using the gear lever or steering wheel gear-change controls for an even more engaging drive.
