Vocis initially created a demonstrator vehicle using a donor Audi A3 3.2L DQ250 6 speed wet dual clutch transmission to showcase the Siena software and the company's DCT experience. This vehicle remains in use today and is regularly used to test customer programme software where development cars are in short supply (typical in many high value vehicle programmes).
In 2008 Vocis added another Audi A3, this time a 1.4L T/C DQ200 7 speed dry dual clutch
transmission to showcase experience in this area.
This latter vehicle has now been replaced with a new stop-start equipped version of the same vehicle to also show this capability for Vocis DCT control software.
