I completely disagree; Renault when buying Dacia, bought a company capable to produce a compact car at a ridiculously low price on an industrial platform that was proven (Clio) and on a market segment that is the bread and butter of all major European car manufacturer. However the same car was sold at almost twice the price within the EU single market as it was outside it.
Before that, you had the experience of FIAT with a single platform produced in Europe (FIAT Uno) and South America (Fiat Palio). It was a commercial success for the company. However, the price for the Palio was lower than the Uno, as it was targetting developing market.
The more mature market are not benefiting from technological development from those cars, as they are based on proven platform (read already paid for), or from the price reduction, as the competition is locked in place, and an aggressive price politic might actually be detrimental to the product perception. This is without even mentioning the cartel like behaviour or European car manufacturer.
I think you miss the point of the article, which is about Renault finding in India an opportunity to be as disruptive as Tesla is in the First World, with diametrally opposed products, but similar appeal to their respective markets by proposing an affordable yet radically new product.
