What is semi automatic?

Hi Teresa,

In general it's used to describe an automatic gearbox that can also be switched into a mode where the driver takes control of the gear changes. There's no clutch operation needed. Most of the time, what is referred to as a semi automatic transmission uses the same components as a manual gearbox, but the clutch operation is done by electro hydraulic means. Some people refer to the latest generation of dual-clutch gearboxes as semi automatics too.

In summary, it's an automatic, but with extra functionality. Note that they're not usually as smooth to drive as conventional automatics.
