In terms of differential gear production, the company reached 100 million gears in 2013 and 200 million in early 2018. The third hundred million took three years, while the 400 million mark arrived within two and a half years of that. The most recent 100 million gears were turned out in under two years which is the fastest century yet.

Differential assembly production began at Sona Comstar's Gurugram plant in 2008, with a second facility added in Pune in 2014 and a third opening in Manesar in 2019. The one-millionth assembly was produced in 2017, with the five-million mark reached in 2023. The following five million were completed in under three years.
