Disclaimer: I do not intend to predict the outcome of any crash test of an Indian MG Astor from the following data, however, it may have some relevance. No one asked for it, so feel free to ignore this post if it doesn't interest you.
I've been looking at scores of different versions of the MG ZS around the world in previous crash tests, and have made the following observations.
I've been able to locate results of four NCAP tests of the ZS in total - three of the fossil-fuel car and one of the EV (which is shared across two NCAPs).
Since it is pointless to compare star ratings for the tests, I'll be looking at just the frontal offset test scores for the cars. A few points to note - firstly, all the results involved use the newer HIC15 head injury criterion, as opposed to the HIC36 criterion used by the SaferCarsForIndia program by Global NCAP which currently operates in India. I have a feeling that the performance limits have been adjusted to meet the same percentage risk of head injury, however, this goes unconfirmed and I welcome any inputs in this regard. Secondly, the performance limits for chest compression have been revised and hence made more stringent in these tests, i.e., the lower performance limit (the value above which the region is marked red) has been changed from 50mm (SaferCarsForIndia) to 42mm, and since the score for a region is determined through linear interpolation, the colour of the body region will be affected in different protocol. Third, and most important,
we have absolutely no idea whether the Astor sold in India will perform similarly to the ZSs tested internationally before. For this reason alone, I think this little exercise of mine may be pointless. We know all too well by now that we shouldn't use data from international cars for ones sold in India.
For the sake of this comparison, I will ignore the above changes. While it is possible to determine the range of values the chest compression score would take under Global NCAP protocol, it is rather cumbersome, time-consuming, and gives no definitive outcome (you only get a range of values) (pretty much like this exercise of mine). Anyone who is willing to do it is welcome, but I will not. For reference, I will list equivalent Global NCAP scores for the chest for the two results published by ANCAP (since they have printed the exact score already in the detailed test report - the other NCAPs haven't) but I will not use it for fair comparison.
1) 2017 MG ZS, petrol, Euro NCAP (3 star rating)
This car scored 12.2/16 points in the frontal offset test, which is squarely in 4-star territory in a Global NCAP test (even if it gets marked up for seatbelt reminders).
The worst performing chest is yellow, which may improve to green and hence increase the test score in a Global NCAP test, though I don't know by how much (as I said before, it is possible to find a range).
2) 2017 MG ZS, petrol, ANCAP (independently tested locally in Australia) (4 star rating)
The car scored 10.46/16 points in the frontal offset test, which sits in 3-star territory in a Global NCAP test although it could score 4 stars if it gets marked up for seatbelt reminders.
Again, the worst performing chest is yellow, so the score could improve in a Global NCAP test. ANCAP has listed the chest score as 2.79 points in their PDF, which indicates a chest compression reading of 28.05mm. This corresponds to a Global NCAP score of 3.16 points, thus bringing the offset test score to 10.83, still in 3-star territory (4 with seatbelt reminder points). However, I believe there may be a flaw in my assumption here since the data at the bottom of the PDF shows that the chest compression was 30.47mm. Anyone who can understand why this is is more than welcome to point it out.
3) 2017 MG ZS EV, EuroNCAP (result shared by ANCAP) (5 star rating)
This car scored 14.71 points for frontal impact which is in 5-star Global NCAP territory (after some additional requirements).
Again, the worst performing chest is yellow, so the score could improve in a Global NCAP test. ANCAP has listed the chest score as 3.83 points in their PDF, which indicates a chest compression reading of 22.85mm. This corresponds to a Global NCAP score of 3.87 points, thus bringing the offset test score to 14.75, which is in 5-star territory
4) 2020 MG ZS petrol, ASEAN NCAP (2 airbags) (5-star rating)
This car scored 14.27 for frontal impact, which is in 5-star Global NCAP territory.
Here the worst performing chest is orange but since the score could only go up, it's safe to say this version would be a 5-star car if tested by Global NCAP if additional requirements are met.
My point in doing this was - why is there an inconsistency in results and which version will we get in India? It looks like some changes to the restraint systems were made for different versions, but I cannot figure out what they are or whether will make it to India. Of course, I could just hold my horses for two days, but I'm very curious, because

MG Astor will be one of the safest car in the segment. As per source, MG is planning to launch Astor with 5 Star NCAP safety rating.

I cannot figure out whether this means MG has sponsored a Global NCAP test and has agreed to have the results revealed at launch, or whether they are simply going to advertise the ASEAN NCAP rating (like Nissan is doing) of the fourth car tested above, despite the fact that ASEAN NCAP ratings are not valid for India and the cars come from different factories (and were tested to different protocol). If they do the latter, how are we supposed to ascertain that the changes that seem to have been made to later iterations of the ZS like the ASEAN-spec car will be made to the Indian Astor?
Insider information, if any, about the Astor's NCAP rating would be greatly appreciated.
