Tata Nexon

Unfortunately, none of the turbo petrol options you listed will be very efficient. Given your limited running, this should not be a concern.

We would recommend choosing between the Skoda Kylaq and the Mahindra XUV 3XO. Both are engaging to drive, offer strong turbo petrol engines, smooth 6-speed torque converter automatics, and a comfortable ride.

The key difference is space. The Mahindra is the better five-seater thanks to its wider body, while the Skoda offers a larger and more practical boot.

The Tata Nexon remains one of the highest-selling cars in the segment, but it is also among the oldest and is due for an update.

If you want a torque converter automatic transmission, the Skoda Kylaq is your best bet. It is powered by a lively 999cc 3-cylinder turbo-petrol engine, paired with a smooth 6-speed AT, with a suspension setup that makes driving the Kylaq fun.

The Hyundai Venue HX5 is the better pick. It's got the smoother and more refined engine, as well as the easier-to-modulate clutch. There's a more modern and airier vibe to the Venue's interior, too, and cabin quality is superior.

The Tata Nexon Creative does pack in a few more features over a Venue HX5, but the Hyundai does get the nicer touchscreen. A big miss on the HX5 is a rear wiper, though. It's a pity that the Hyundai Venue diesel manual doesn't come in higher-spec HX6 form that would have been the sweet spot in price and features.  
 

Things that set the Nexon apart are its tough build and rugged suspension that can take quite a beating. The Nexon has been around for a while and, despite frequent updates, has started showing its age in the face of new competition. 
 

Of these two, we'd recommend you choose the Hyundai Venue HX5. The Tata Nexon has the slight edge on driving enjoyment with its punchier engine, sharper steering and better-tuned suspension, but in most other areas, the Venue excels. 

The HX5 variant is decently well equipped, and the Venue diesel in general is smoother, more refined, better built and of higher interior quality. Plus, Hyundai's aftersales and service are known to offer a better experience than Tata's.

There are only two options that would meet your requirements of a diesel automatic and under Rs 13 lakhs. These are the Mahindra XUV 3XO and the Tata Nexon. It would be nice to know a bit more about your requirements to pinpoint one. 

The Tata Nexon is a good option, as fuel efficiency is very important for you, as its efficiency is higher than the 3XO. In our real-world tests, we got an average of 18kpl for the Nexon and 15.5kpl for the Mahindra. 

If, however, driving pleasure and interior space are important, then you would be better off in the 3XO. The engine is refined and delivers good performance. Also, the car is spacious from inside, especially at the rear, where you will find more passenger room than in the Nexon.
