Q. Which is better among Brezza AMT Nexon AMT and Venue DCT?

One correction, brezza is not AMT its torque convertor automatic.AMT vs dct vs torque convertor is a good puzzle to solve. For me only for engine I would have gone for torque convertor with suzuki hybrid technology which assure decent milage. Dct the most advanced technllogy but reliability and possible higher maintanace cost is an issue. Amt is common man's automatic with low maintanace. I will choose nexon AMT mainly because it is a slightly better car compared to other two.

Both AMT and DCT have advantages and disadvantages. DCT is pretty smooth compared to AMT. AMT cars have the same manual gear box with sensors fitted to automate the clutch and gear shift operation. hence from a maintenance point of view it is much cheaper than DCT. You will feel the gear changes happening in AMT whereas it won't be felt in DCT. Overhauling the DCT gearbox is much expensive compared to AMT. DCT would get heated up faster during bumper to bumper long traffic city driving unless it's a oil cooled DCT gearbox (wet DCT gearbox) like the recently launched Tata DCA. AMT can give more mileage compared to DCT depends on the individuals driving style.

Nexon amt and venue dct are good choice but if you you want smooth drive in city than venue DCT is best option , there is no any leg in dct
