Global NCAP has expressed disappointment following a zero star ratings for crash test results across five models.
The Renault Kwid, Maruti Suzuki Celerio, Maruti Suzuki Eeco, Mahindra Scorpio and Hyundai Eon all tested low for adult occupant protection.
Despite being tested in three versions including one with airbags, the Renault Kwid still scored zero for safety.
Global NCAP secretary general David Ward said that car manufacturers should be considering car safety during the entire process of production.
"The latest SaferCarsforIndia results show how important it is for cars to have a body shell that can remain stable in a crash.
"This is an absolutely crucial pre-requisite for occupant safety together with fitment at least of front air bags.
"It is very surprising that a manufacturer like Renault introduced the Kwid initially lacking this essential feature.
"Global NCAP strongly believes that no manufacturer anywhere in the world should be developing new models that are so clearly sub-standard.
"Car makers must ensure that their new models pass the UN's minimum crash test regulations, and support use of an airbag."
Ward did however applaud Renault for its efforts to correct the safety of its cars in India based on its European models.
In addition, he also commented on the importance of the Indian government's decision to enforce greater regulations for car safety.
"The results highlight the importance of the Indian Government's decision to mandate front and side impact crash tests from October 2017.
"Legislative action is needed to ensure that the minimum levels of occupant protection recommended by the United Nations are guaranteed for Indian consumers.
"But manufacturers don't have to wait for legislation and we urge them to act to eliminate all zero star cars from production as soon as possible.
"Global NCAP also welcomes the forthcoming launch of a Bharat New Car Assessment Programme which can help build a market for safer cars in India."
