I understand your intentions, but blindly believing modern cars are safer just because they’re modern isn’t exactly a good mentality either.
For instance: the Volkswagen Up!! Being safer than the Renault kwid which is still better than the equally modern fiat panda, which got the lowest possible grade.
Remember: the auto industry will not make safer automobiles without pressure, I know this because the volkswagen T2 was built all the way to 2014 only getting performance or interior updates because of the lack of pressure on them to make a safer vehicle for that class.
Edit: also do note that the kwid built on Brazil is significantly different from the Indian kwid, meaning that one got 3 stars and the other only one.
As a side note: the Volkswagen Up! performed well when it was tested in 2014 by latinncap
