Indian Auto Industry Shows Mixed Performance in September 2025: SIAM Data

The Society of Indian Automobile Manufacturers (SIAM) released its monthly domestic sales report for September, revealing a varied performance across different vehicle segments with overall positive momentum in the passenger and two-wheeler categories.

Total passenger vehicle sales reached 3,72,458 units in September 2025, registering a 4.4% year-on-year increase from 3,56,752 units sold in September 2024. The modest growth reflects steady consumer demand in the passenger vehicle segment despite ongoing economic headwinds.

The three-wheeler segment demonstrated robust overall growth of 5.5%, with total sales climbing to 84,077 units compared to 79,683 units in the previous year. However, the segment showed divergent trends across categories: Passenger carriers saw a marginal decline of 8.9%. 

The two-wheeler category continued its upward trajectory with 6.7% growth, reaching 21,60,889 total units. Within this segment:

• Motorcycles  5.8% growth, hitting 13,73,750 units
• Scooters up 9.1% at 7,33,391 units
• Mopeds relatively flat 53,748

The September data suggests that India's automobile sector is maintaining recovery momentum, particularly in personal mobility segments. Industry analysts will be watching closely to see if these trends continue through the festive season, traditionally a strong period for automobile sales in India.
