I checked with VW site and they haven't put the information there. I am sure we can have lot of features in T jet that is not there in Jetta. Also Jetta petrol is coming in Mid model. Later when they introduce the top model imagine the price. I haven't seen a review where some body had not exited by Tjet drive. But Jetta had given the impression that it is not electric. Remember When they introduce Jetta they come with 1.6 engines. They thought that people will buy anything because of VW badge. It was a failure. Only in B segment people will blindly go for brand without looking what they are getting.
