Global NCAP Requirements for 5-star rating Unlike Euro-NCAP or Australasian-NCAP, Global NCAP doesn't award a combined overall star rating. Instead it tests and rates vehicle for Adult Occupant Safety and Child Occupant Safety separately.
I am attaching copies of the relevant assessment criteria as used by GNCAP.
Normally the latest assessment protocol/criteria are always uploaded in the respective NCAP website. Currently on GNCAP website, for adult occupant protection, the latest version is "Version 1.0, August 2017". Assuming we are referring to 5-star rating for Adult occupant protection, following is the criteria: Quote: 3.3 Scoring & Visualisation
The protection provided for adults for each body region are presented visually, using coloured segments within body outlines. The colour used is based on the points awarded for that body region (rounded to three decimal places), as follows:
Green 4.000 points
Yellow 2.670 - 3.999 points
Orange 1.330 - 2.669 points
Brown 0.001 - 1.329 points
Red 0.000 points
For frontal impact, the body regions are grouped together, with the score for the grouped body region being that of the worst performing region or limb. Results are shown separately for driver and passenger. The grouped regions are:
- Head and Neck,
- Chest,
- Knee, Femur, Pelvis (i.e. left and right femur and knee slider)
- Leg and Foot (i.e. left and right lower leg and foot and ankle).
The contribution of the frontal impact test to the Adult Occupant Protection Score is calculated by summing the body scores for the relevant body regions, taking the lower of the driver and passenger scores. The total achievable score is 17.00 points and the overall scores are then used to generate star ratings as follows:
Frontal Impact:- 14.00 – 16.00 points + 1 point SBR + 4ch ABS + ECE95* --> 5 stars
- 11.00 – 13.99 points --> 4 stars
- 8.00 – 10.99 points --> 3 stars
- 5.00 – 7.99 points --> 2 stars
- 2.00 – 4.99 points --> 1 star
- 0.00 – 1.99 points --> 0 stars
*To be eligible for 5 stars the car must score over 14 points in the ODB test (after application of modifiers).
In addition, it must have the full point on SBR, 4 Channel ABS and offer some side impact performance protection. To demonstrate the latter, a MDB test must be sponsored by the manufacturer on an actual Global NCAP market car of the identical specification as the frontal crash car according to the test specification of ECE R95. The MDB test would need to be performed even in cases where under the regulatory requirements the vehicle would be exempted due to various reasons, for example seating position. In order to qualify for 5 stars, the performance criteria of ECE95 should be met. The test results may be published by Global NCAP. Where the car is equipped with a side protection airbag (curtain or thorax side airbag) the airbags should be standard fitted.
In order to avoid the highly undesirable situation of a vehicle gaining a rating of multiple stars when an important body region is poorly protected, the rating will be limited to no more than 1 star regardless of the total number of points scored.

Basically this means that for vehicles which are already rated 4 stars, for them to reach 5-star rating, only the following are required: - Achieve a score greater than 14.00 for front offset-deformable barrier (ODB).
-- Currently none of the 4-star rated cars have a score greater than 14.00 -- Nexon has the highest score of 13.56, but this would be including SBR score for driver seat. -- Having driver knee airbag helps for better score in front ODB test. Yaris has an advantage here. - 4-Channel ABS
- Seat belt reminder (SBR) for all front row seats
- Conformity to a side impact crash test using a Moving Deformable Barrier (MDB): The vehicle would ideally need side and curtain airbags to pass the same.
Other safety features like ESP, SBR for rear seat or any of the passive/active ADAS systems are not mandatory at the moment for achieving a 5-star rating as per GNCAP. This is not particularly tough to achieve and far less stringent than the ENCAP, ANCAP or IIHS ratings.
To be able to achieve 5-star rating for entire model line-up base car will need to be tested. Else if manufacturer is happy to sponsor the test and rate a higher spec variant or one with safety pack option, they may do so also. The model will then have two ratings, one for the base variant and one for the higher spec/safety-pack variant.
So the Yaris looks more likely to be the manufactured in India vehicle that could achieve 5-star rating across its variant range for adult occupant protection. Quote:

As of now, for achieving 5-star rating in G-NCAP test, availability of ESP is not mandatory, nor rewarded with additional points.
