HYDERABAD: Tata Motors ' share in taxi aggregators' fleet has more than halved in one year, mainly due to a change in the business model of app-based cab operators such as Ola and Uber , a top official at the Indian auto major said.“The volume of aggregators started declining since October last year and we have seen more than 50% decline in this,“ said Mayank Pareek, president (passenger vehicles business unit), Tata Motors.“Their share (in Tata Motors' total passenger car sales) has come down to 10% from 20-25% two years ago due to a slow growth in volumes and also because of an improvement in the share of individual taxi owners,“ he said.Tata Motors now plans to enter new vehicle segments to expand its market coverage and increase its share, said Pareek, who was in Hyderabad to launch the company's compact sports utility vehicle (SUV) Nexon. “We are not present in premium hatchback, big SUVs, van,“ he said.“With the launch of Nexon, we entered the compact SUV segment and will be entering new segments in the next few years, increasing our auto market coverage to 95% by 2020 from the 71% currently.Pareek, who was in Hyderabad to launch the company's compact sports utility vehicle (SUV) Nexon. “We are not present in premium hatchback, big SUVs, van,“ he said. “With the launch of Nexon, we entered the compact SUV segment and will be entering new segments in the next few years, increasing our auto market coverage to 95% by 2020 from the 71% currently.Tata Motors is also working with various digital partners to set up virtual showrooms using artificial intelligence and virtual reality to provide customers a feel of its vehicles without having to set up a showroom for the same.
