New city is BIGGER.
"As regards the dimensions, the India-bound sedan will measure 4,549 mm long, 1,748 mm wide and 1,489 mm high with a 2,600 mm wheelbase. The new model is considerably bigger than the outgoing model. Specifically, the new model will be longer, wider and shorter by 109 mm, 53 mm and 6 mm, respectively, than the previous model with the wheelbase maintaining the same. The significant improvements in the dimensions will lead to a more spacious cabin."
That's Indian City in discussion here.
