Engineers typically use these roads for validation of transmission 
and braking systems, which one would expect this early in the car’s 
development. As this is only a mid-cycle update (the second-generation 
Touareg has been on sale since 2011), the visual changes to the car will
 be modest. Camouflage gear on the front and rear sections of this 
prototype suggest we’re likely to see some new bumpers, a revised grille
 and possibly some changes to the lights. Inside, Volkswagen is expected
 to update the infotainment system by installing its latest modular 
unit.
The
 system is based around a capacitive touch-screen mounted in the dash 
that will allow the driver to control most of the vehicle functions via 
the screen, or by using voice or steering wheel controls. Though it’s 
yet to be confirmed, we could also see output of some of the Touareg’s 
engines increased for the 2015 model year. The 3.0-liter turbodiesel V-6
 in the TDI model could see its current 225-horsepower rating boosted to
 somewhere around 260 horsepower and overseas we could see a 
four-cylinder engine added to the lineup. Source www.motorauthority.com
