According to the company, the new product offerings are part of its new customer-focused strategy for its passenger vehicles termed as 'HORIZONEXT' which comes after the automobile major suffered falling sales in recent months.
The company's passenger cars sales in May fell by 15.5 percent from the sales in the corresponding month of 2012 and stood at 43,142 units.
"While the Indian automobile market has become intensely competitive, our goal is to enhance our market leadership in commercial vehicles and move to a strong podium finish in the passenger vehicle market," Karl Slym, managing director, Tata Motors said in a statement.
"Horizonext is the next step in line with the company's mission to be passionate in anticipating and providing the best vehicles and experiences that excite our customers globally."
The company also unveiled eight new improved vehicle variants, across five of its key brands, as a precursor to future launches.
The new versions include Tata Indigo eCS, Tata Sumo Gold, Tata Nano and Tata Indica as well as the new CNG (compressed natural gas) powered range which include Tata Indica CNG, Tata Indigo CNG and Tata Nano CNG and the explorer edition of Tata Safari Storme.
The new variants come with the additions of enhanced interiors and exteriors, improved suspension and introduction of the feather-shift gearbox.
