Fuel consumption of both the 150kW tune and the high-power version, which is up from 180kW to 193kW, both fall to 6.6 litres per 100 kilometres, representing economy improvements of six and eight per cent respectively based on European data. Torque is understood to carry over unchanged at 400Nm for the entry model and 550Nm for the higher tune.
Carbon dioxide emissions dip to 173-174 grams per kilometre, while the introduction of a ‘selective catalytic reduction’ catalytic converter is said to significantly reduce the amount of nitrogen oxides in the exhaust fumes.
Touareg V6 TDI models gain a coasting function, where the standard eight-speed automatic transmission is disengaged to utilise kinetic energy when no acceleration is required.
Aerodynamic refinements to the Touareg’s body and underbody and low rolling resistance tyres contribute further to the efficiency gains.
Volkswagen Australia general manager communications Karl Gehling confirmed the updated model would reach local showrooms in the first half of 2015.
Highlights of the updated model include refreshed exterior styling, new interior materials, retuned suspension, a ‘stop and go’ function for the adaptive cruise control system, and a new mobile online services feature with integrated Google Street View, Google Earth and Google points of interest searches.
Australian specifications will be confirmed in the coming months, closer to the 2015 Volkswagen Touareg's local introduction.
