Can't really argue against that, even though Volkswagen's 3-cyl 1.0 TSI is still more expensive to manufacture than a naturally-aspirated 4-cyl 1.6 MSI fitted to most export versions of the Brazilian-made Volkswagen T-Cross for instance. Had it been something like replacing a 4-cyl 1.6L with a 3-cyl 1.5L instead, and both being naturally-aspirated, would've made more sense not only from a cost perspective but also due to all those claims regarding pumping losses and other factors leading to some effective impact to the overall efficiency of an engine.
