To supply the Volkswagen Tiguan diesel version in the United States, at least three years will wait yet. This is not because there is no demand for this model. Volkswagen leaders explained that dealers and buyers demanded the version of TDI, starting from the year of launch of the model in 2009. Then VW said that he was studying the possibility of launching a diesel option in the United States. VW begins to review 2012 Tiguan. VW planner John Ryan noted that European supplies are 27% more effective than similar models from 2.0-liter gasoline turbine engine I-4. The technology of the diesel engine is inexpensive, but will require a lot of means to develop in order to reduce the level of emissions of CO2 to meet the current standards. Tiguan TDI models use 2.0-liter diesel engine with turbocharged I-4. This engine is also used on golf TDI and Jetta TDI. However, Ryan noted that since Tiguan is a heavier model, it will be necessary to use the catalyst system (known as Adblue) based on urea, and not on nitrogen oxide used on smaller TDI models. Volkswagen cars are already using Adblue on Passat TDI and TOUAREG TDI, but this system is more expensive than the comparable NOX system. This is not a problem for premium models such as Touareg, but Tiguan is an entry -level vehicle. Therefore, it is impossible to increase the price of the model without making it competitive.
