The challenge will be more towards convincing customers to shell out more for vehicles with just an upgraded engine, industry observers opined.
However, with the demand environment showing signs of stability and inventory levels under control, this transition is likely to be less problematic unlike that of BS-IV.
Nonetheless, the general economic slowdown will make the task even tougher as high tax rate and lower rise in average wage growth will deter many from making a purchase.
The Indian automakers are all set for transition to BS-VI from April 2020.
"The challenges the industry still faces include lack of positive sentiments with slowdown still persisting, finance availability, transition to BS-VI more so on the commercial vehicles segment," Grant Thornton India LLP Partner, Sridhar V. told IANS.
"Most oil cos have expressed that upgraded fuel will be available."
Furthermore, Rahul Mishra Principal at A.T. Kearney pointed-out: "The one big challenge will be to sell old models with just an upgraded BS-6 engine."
"It will be difficult to convince the customer to to buy the same product, with any change in features but with the better engine -- a difference that a common user can not even see."
The price increase will have to be supported by new or facelift products where the engine upgrade is part of a broader upgrade package with changes that are visible and valued by customer, Mishra added.
According to ICRA Senior Analyst Sruthi Thomas: "The first three months of the year would continue to be subject to uncertainties emanating from the impending BS-VI transition... Phasing out of BS IV inventory and stocking up on BS VI inventory in a balanced manner would be a key challenge for the OEMs."
"There is expected to be a material increase in vehicle prices across automotive segments with the transition to BS VI emission norms. Accordingly, demand, especially in price-sensitive segments, are likely to be impacted."
The latest challenge comes after 12-months of relentless sales truncation due to the demand slowdown on account of high goods and services tax (GST), farm distress, stagnant wages and liquidity constraints.

Recently, a Motilal Oswal Institutional Equities report said the stability has partly appeared due to high discounts, better availability of finance and improvement in rural sentiment.
"After operating in a tough environment over the last 15 months, the auto industry now faces the last hurdle of BS6 transition, post which it will likely be 'business as usual' from 2HFY21, in our view," the report said.
