I currently own a 2016 Ford Figo diesel manual with around 62,000 km on the odometer. My annual usage is about 8,000-10,000 km, mostly in bumper-to-bumper Mumbai traffic, with occasional highway trips two to three times a year. Given the traffic conditions, I am considering switching to an automatic. However, after test-driving a few petrol cars, I felt they lacked the torque and handling I am accustomed to in the Figo. Should I retain my current car for a few more years or upgrade to a new one? If upgrading, please suggest an SUV that offers strong performance with decent mileage.

If you are happy with the Ford Figo and it is running fine, you could hold on to it, however it will get progressively difficult to maintain it. Thus, if you can change it might be a good idea to do so now. 

Consider the Maruti Suzuki Fronx / Toyota Urban Cruiser Taisor. The car will feel similar in its fun-to-drive character to your Figo, and you could opt for either the turbo or the naturally aspirated engine. 

The 1.0 litre turbo will be more peppy and fun to drive but given that turbo's are very sensitive to driving style, you will likely see real world efficiency figures than quote. In this regard, the 1.2-litre naturally aspirated engine will be better, though at a lower performance level. 

Test drive the two and see which you prefer.
