Launched in April 2016, Tiago was the first car to embody the company's impact design philosophy.
"Tiago boasts our new IMPACT design philosophy and has been a game changer for Tata Motors," the company's President, Passenger Vehicles Business Unit, Mayank Pareek, said in a statement.
With its design, performance and drive dynamics, Tiago led the company's transformation journey, setting a benchmark in the hatchback segment, he added.
"We have witnessed a healthy month-on-month growth on the back of a strong demand. The car is making all the right noises in India. We are extremely happy with the response received so far and are confident of achieving more milestones in the months to come," Pareek said.
