Currently, the cheapest Volkswagen you can buy in the US is the Jetta, which retails for $16,720 and is powered by a 2.0-liter 4-cylinder engine making 115. It's also available with the 2.0-liter 140 hp TDI and the 210 hp 2.0 TSI turbo. Following that logic, the Polo would have to be sold with a basic 1.6-liter engine and maybe in GTI form as well. A 1.2-liter TSI would make far more sense, but we're not holding our breath.
Motor Trend also says a subcompact CUV will be sold in the US. It would be based on the MQB platform and look a bit like the CrossBlue Concept from earlier this year. Much of the architecture would be shared with the Polo. However, they also say this CUV won't be ready until 2016 or 2017.
Currently, VW sells something called a Cross Polo in Europe. It's a jacked up version of the Polo with black plastic and slightly wider track. However, we expect that given the popularity of subcompact crossover, a whole new body will be designed for the America-bound CUV.
