If you look at the site below, there's a reference to something being called a SEQUENTRONIC in the new C-Class Hatchback:

Electronic gear changes with the new SEQUENTRONIC
A further new development to make its debut in the C-class sports coupé is the optionally available automated six-speed gearbox, SEQUENTRONIC. The dynamic driving experience is enhanced still further by its fast, agile and precise gear changes, whilst fuel consumption is actually reduced. The driver's intention to change gear is communicated to the gearbox by electrical impulses, making mechanical linkages and the clutch pedal superfluous. A light tap on the shift lever is all that is needed for the system to declutch, change gear and engage the clutch again. In automatic mode, the SEQUENTRONIC system makes life easier for the driver, since it changes gear (on its own) according to the particular driving situation.

This seems different from the current Mercedes "TouchShift" which is more or less a Steptronic like unit.

Any thoughts...?
