I'll start by saying this: I mean no offence to you, sir, or any creta owner. I'll link the IIHS study pertaining to the video you sent above (the link in description was dead, so I googled the new link with updated tests):
https://www.iihs.org/topics/vehicle-size-and-weight https://www.iihs.org/news/detail/iih...cles-for-teens
I'll quote some excerpts from the links above and the same can be duly cross checked from the given source.

A bigger, heavier vehicle provides better crash protection than a smaller, lighter one, assuming no other differences. |
This line was confusing at first, but it becomes clear in the light of the tests conducted (read below).
Quote:
IIHS demonstrated the role of size and weight in a series of crash tests in 2019, pairing a midsize SUV and small car made by Kia and a large car and minicar made by Toyota in collisions with each other. Both of the smaller vehicles, the 2018 Kia Forte and 2018 Toyota Yaris iA, had good ratings in the five IIHS tests relevant to driver protection, but they performed poorly in collisions with the larger vehicles.
|
It may be inferred that the relatively smaller/lighter cars had good crash test ratings vs unknown ratings of the cars being considered here. In fact, googling the crash test ratings of all the models mentioned in the tests, from the respective years, suggests that all the cars crash tested had good crash ratings (this might be what the above line '
assuming no other differences' alludes to).
Quote:
The structures of the Forte, which weighs 928 pounds less than the Sorento, and the Yaris iA, which weighs 1,033 pounds less than the Avalon, didn't hold up as well against the larger vehicles as in the car-to-barrier tests on which IIHS ratings are based.

Roughly translates to ~421 kg and ~469 Kg respectively. The point of contention here is, what type of weight is used in judging the crash worthiness? The kerb weight? The Gross weight? I decided to stick to kerb weight for the time being, please correct me if needed. Any help here would be appreciated. So I tried finding the kerb weight of Indian Creta, but it seems Hyundai has omitted this part from the Indian owner's manual, hence I used the weight of the African Creta, which may or may not be representative of the Indian Creta; I hope it serves the purpose of being informative, if not absolute. I will attach the images and mention the sources for the same below.
The kerb weights are as follows:
Petrol Creta:1165-1230 Kg
Petrol City: 1107-1153 Kg
Diesel Creta: 1270 Kg
Diesel City: 1191-1217 Kg

In larger-sized vehicles, the longer distance from the front of the vehicle to the occupant compartment provides more protection in frontal crashes, which account for more than half of passenger vehicle occupant deaths. The longer that distance, the more the frame of the vehicle can be crushed before it crushes the people inside.

I do not have the required data of the respective distances to compare. Maybe someone can come chime in
Quote:
Weight is important when two vehicles collide. The bigger vehicle will push the lighter one backward during the impact. That puts less force on the people inside the heavier vehicle and more on the people in the lighter vehicle.

The part that probably supports your assumption.
Quote:
Large vehicles aren't as big a threat to people in small vehicles as they used to be. A lighter vehicle will always be at a disadvantage in a collision with a heavier vehicle. But in recent years automakers have reduced the threat SUVs and pickups pose by more closely aligning their energy-absorbing structures with those of cars. |
Now, the Creta is not an SUV in the traditional sense, which to be fair, the Sorento labelled as midsize SUV by IIHS in the test above isn't either, both being monocoque; the difference lies in Sorento having a good crash rating vs the unknown rating of the Indian Creta, in addition to being significantly heavier than the Kia Forte vs not as significant weight differences between the Indian City and the African Creta, especially if you compare equivalent variants of the two (i.e. petrol automatic Creta vs petrol Automatic City, and so on). What the above also points to, is, modern SUV's being less fatal to the passengers of the cars they collide with as compared to the old, traditional SUV's.
Considering my interpretation of the points above (please do correct me in case I wrongly interpreted the linked articles), I think it would be unfair to give Creta the weight advantage when speculating its crash worthiness against the City, especially since its Korean sister Seltos fared poorly in crash tests, which was supposedly built on the same platform (I might be inaccurate on this one, please correct me in such a case).
This leads me to a hypothetical question. In the hypothetical case of City being a 5 star car and Creta faring the same as Seltos, 3 star; would the kerb weight difference of 40-80 Kg between equivalent variants of the two, tip the crash worthiness in favour of Creta/Seltos?
Again, I'll repeat what I said at the start, this is not meant to offend any owners/ berate any product. Please view it as a mere opinion and/or a curious question.
