In fact, this is what happened after the tough times of Volkswagen’s diesel generation. All types of engines stopped being produced, at least for two years after the big scandal. 2018 VW Jetta TDI is part of the project, 2018 is the time when the company plans to start back diesel engines. At least they are serious to do so, but for the American market will be very difficult because in 2019 the regulation of diesel engines more stringent. It looks like the TDI version will not be marketed in America.
2018 VW Jetta TDI will likely only exist in Europe market with better system and technology. Volkswagen is not alone in this case, there is Audi and Porsche are also using the same basic engine. They will strive to make significant changes to their previous diesel engine type. Audi is optimistic to keep the 3.0-liter engine when the problem is resolved. Smentara Porsche is also still trying to maintain the diesel engine in the body Cayenne Diesel.
We can not expect much with the 2018 VW Jetta TDI, this is just a model that is still far from being expected. Until this problem can not be solved by the company then any diesel model in the Volkswagen range seems too early to be expected. If you are one of the TDI model fans then this should stop for an indefinite time. Maybe the previous model can entertain you.
