* Emissions Regulations: The 1.6 FSI engine was a naturally aspirated petrol engine, which struggled to meet increasingly stringent emissions standards, especially the Euro 6 standards that were introduced in 2015.
* Fuel Efficiency: Newer turbocharged engines offered better fuel economy and performance compared to the naturally aspirated 1.6 FSI. This made them more appealing to consumers and aligned with VW's goals of producing more efficient vehicles.
* Market Demand: The 1.6 FSI engine wasn't as popular as other engine options offered in the Touran, especially the more powerful 1.4 TSI and 2.0 TDI engines.
* Technological Advancements: VW focused on developing more advanced engine technologies, such as the 1.4 TSI and 2.0 TDI engines, which offered better performance, fuel economy, and emissions.
Therefore, the 1.6 FSI was gradually phased out as newer, more efficient and environmentally friendly engine options became available. It wasn't necessarily dropped abruptly, but rather gradually replaced as VW shifted its focus to other engine technologies.
