Volkswagen and some attempts to get rid of naturally-aspirated engines since 2003: why the Virtus is an example of turbocharging being far from one-size-fits-all?
The presence of a turbocharger might not be a maintenance nightmare at all, yet it does have its fair share of complexity due to the high temperatures a turbocharger tends to operate and how it may require a stricter observance of the minimum specifications for motor oil. Sure using a lower-grade oil in a modern naturally-aspirated engine may not be a good recommendation at all, and neither adapting a carburettor instead of the electronic fuel injection like it often happens in Argentina as the do-it-yourself culture is still quite common there and inviting to some makeshift, even though it may lead to other electronic systems to fail considering the greater integration between the engine management system, some accessories, and safety devices such as ABS brakes and traction and stability controls. It's also worth to notice in some countries the Virtus was introduced only with manual transmission and the 1.6 MSI engine, such as South Africa where it's sourced from India and named Polo Sedan instead, and its powertrain contrasts with the all-turbo lineup and the availability of the DSG transmission for the South African Polo hatchback.
