New Delhi, Sept. 12 -- A study byVector Consulting Grouphas revealed thatlate-stage engineering changesare a major reason for vehicle launch delays inIndia, especially in the growing electric vehicle (EV) segment.

About 80% of original equipment manufacturers (OEMs) said such changes disrupt production schedules, affect supplier capacities, and weaken India's competitiveness in the global automotive market.

Ideally, engineering changes should drop sharply as product development progresses - below 15% during pre-production, under 8% during post-launch production, and around 3% after stabilisation. However, only 6% of OEMs follow this ideal trend.

The report found that 81% of OEMs face severe misalignment, leading to repeated validations...
