Hello Autocar, I am using a 4-year-old Tata Nexon AMT, and I suffered a gear oil leakage issue during the third year and an engine oil leakage issue in the fourth year. Due to the engine oil leakage, the engine had to be opened for repairs, and the car remained in the workshop for two months. Since the engine has been opened, I am wondering whether I should replace the car because of these issues. However, the car is running fine now, although I do feel there is a loss of power and mileage. I would like to know whether I should change the car now or wait a few months to understand the roadmap for ethanol blending. Also, my annual running is only around 5,000 km. Would a naturally aspirated engine be a better choice than a turbocharged engine, considering the car would remain idle for long periods? I am thinking of switching to the Maruti Suzuki Brezza TC. However, I like the Kia Sonet's interiors, but I am concerned about its turbo engine and DCT. That said, the Sonet seems like a fun-to-drive car on the highways. My usage will be around 70% city and 30% highway. Please advise.
Given your low annual running of 5,000km and the fact that the car will be idle for long periods, a naturally aspirated petrol engine paired with a torque converter automatic is the most sensible choice. The Maruti Suzuki Brezza fits this brief perfectly. It is a simple, reliable and low-maintenance package with a proven engine and gearbox combination that will serve you well over a long ownership period. The Sonet turbo petrol DCT is the more fun-to-drive option on the highway, but the DCT gearbox is not the ideal choice for predominantly city driving and long periods of idling. As for your current Nexon, if the car is running fine now, there is no immediate need to change it. However, given the engine has already been opened and you are experiencing a perceived loss of power and mileage, it is understandable to want to move on. On the ethanol front, there is no official roadmap beyond E20 at this stage, and modern engines are engineered to handle E20 without issue. There is no need to wait for further clarity. The Brezza is the safer and more sensible long-term choice for your usage pattern.
