Tata Motors wants to equip its future cars based on the Advanced Modular Platform (AMP) with a dual clutch automatic gearbox. This gearbox will be fitted to the 45X, a premium hatchback that was first shown at the Auto Expo 2018. However, Tata is expected to offer this gearbox on the 45X’s production version only in 2020 or beyond as such a gearbox will take at least a couple of years to be developed. The 45X will be launched by the end of next year.
The company believes that the twin clutch automatic gearboxes will give its future cars the twin advantage of sporty, quick gearshifts and good fuel efficiency. Twin clutch gearboxes are similar to AMTs in their operation but with two clutches instead of one. This allows them to shift much more faster than conventional torque converter automatics and CVTs, while not imposing a fuel efficiency penalty associated with traditional automatics.
Tata does not plan to develop the new twin clutch automatic transmission on its own but find vendor who will develop a gearbox to work with new cars that the automaker will launch in future. Tata plans to also involve Jaguar and Land Rover in this project as it’ll give the three companies economies of scale if they together use the new gearbox on new cars and SUVs. For now, even Jaguar and Land Rover don’t have twin clutch automatic gearboxes in their vehicle line up.
The 45X premium hatchback will compete with the Hyundai Elite i20 and the Maruti Baleno in India. The car will use uprated petrol and diesel engines of the Tiago hatchback, which will be tuned to produce more power and torque. The car is expected to be the hottest looker in the premium hatchback space, and will follow Tata Motors’ new Impact 2.0 design.
