Tata Motors has multiple plants spread across India and we had a chance to visit the one in Pune. This plant is tasked with producing Altroz and Punch iCNG models. The visit also gave us a chance to see the twin-cylinder technology being employed in the new Tata cars. It uses two slimmer CNG tanks that have the same volume as a single large tank but can be laid on the floor and as a result, consume much less space. This frees up more areas for owners to keep their belongings in the boot.The plant in Pune has a press shop, weld shop, paint shop and even its own CNG fuelling station. As a result, Tata Motors is able to produce the vehicles entirely at this facility and not be dependent on any outside sources.
