Won't come until the redesigned model is launched
The United States has been stuck with a petrol-powered Tiguan, but increasing demand for diesel engines could force Volkswagen to offer a TDI variant.
VW product planner John Ryan revealed the model is under consideration but there are currently a few holdups. First and foremost, the current 2.0-liter TDI engine - that is offered in the Golf TDI and Jetta TDI - would have to be equipped with an expensive urea-based catalyst system to meet U.S. emission standards. While the company already uses that type of system on the Touareg TDI, the cost would make a Tiguan TDI prohibitively expensive.
Even those issues were resolved; strong TDI demand in Europe has pushed American availability to the backburner.
Despite the problems, Ryan hinted that Volkswagen might iron out the obstacles when the next-generation Tiguan is introduced in 2015.
