Maruti Suzuki India will increase the prices of its vehicles "substantially" from next month as it looks to offset the impact of rising input costs and make provisions to conform to stricter emission norms which kick in from April.

In a regulatory filing on Friday, the country's largest carmaker said it continues to witness increased cost pressure driven by overall inflation and recent regulatory requirements.

The company has planned the price increase in January 2023 which shall vary across models, the auto major said without disclosing the exact amount of the rise.

"The company continues to witness increased cost pressure driven by overall inflation and recent regulatory requirements. While the company makes the maximum effort to reduce costs and partially offset the increase, it has become imperative to pass on some of the impacts through a price increase," the filing said.

Maruti Suzuki India's senior executive officer marketing and sales Shashank Srivastava told The Telegraph that though the commodity prices have softened in the past few months, they are relatively high compared with two years ago.

The price hike carried out earlier this year has reduced the gap but has not fully absorbed the increase in prices.

Another factor for the proposed hike was the regulatory norms that must be met, which would push up the cost of the vehicle.

The company needs to make models ready for the second phase of BS-VI emission norms that kick in from April. “We will have to start making changes in the product range,” Srivastava said.

Vehicles will need an onboard self-diagnostic device to monitor the real-time driving emission levels. The device will constantly monitor key parts for meeting emission standards such as the catalytic converter and oxygen sensors. Maruti said the shortage of electronic components can have more impact on the company's production in December than seen in recent months.
