According to reports in Times of India, instead of Tata Bolt Sport, the Tata Tiago Sport is expected to launch this November. Since the Tata Motors have not yet confirmed the product, so not much technical data is available regarding the Tiago Sport.
Reports also suggest that the automaker will equip the Tiago's 1.2 L three-cylinder Revtron petrol engine with a turbocharger. This will increase the power output to around 120 PS. Also some cosmetic upgrades are expected in the Tiago Sport which include: sportier bodykit, larger exhaust pipe and different alloy rims. Along with the cosmetic changes, the suspension could be decreased and stiffened to improve the handling abilities of the vehicle.
