A report on The Business Line quotes him in saying that the AMT gearbox is in tune with what the company has been hearing from its customers and that it is a feature they want.

The AMT was first announced during the unveiling of the Tata Zest prior to the Auto Expo 2014. At the Auto Expo, the company had showcased a cutaway version of the Tata Nano Twist featuring an F-Tronic five-speed AMT gearbox.
