Kia Sonet vs Tata Nexon: The best compact SUV for Rs 15 lakh

I am looking at the diesel versions, as the car I purchase will have an annual mileage of around 15,000 km.

BHPian krishnakumar recently shared this with other enthusiasts.

Hello BHPians!

I'm looking for a car at ~Rs 15L (max Rs 16 lakh) OTR for my first car ownership. While I'm new to car ownership, I've been driving cars for 10+ years now and have driven a variety of cars during this period.


The one-line requirement goes like this: "a car that'll get us around comfortably on highways and broken roads for long road trips and weekend mall crawl with occasional city usage".

The car will be primarily used by me and my wife (and hopefully a future dog) most of the time. However, we'll have our siblings and parents visit us 2-3 times a year. Hence, rear-seat comfort, while not critical, is not to be ignored completely. I'm also expecting an annual mileage of 15,000km.

Some basic checklist features that I noted down based on above:

High on safety

Great highway stability

High Ground Clearance - so ruling out sedans

Diesel engine - to keep the fuel costs low

Good practical boot size for carrying all the luggage around

Few comfort features that support highway usage like - Cruise control, practical cabin for storage of phone, bottles etc.

The Shortlist

The current cars under consideration are (in the order of priority):

  • Tata Nexon 1.5D XZ+(S)
  • Kia Sonet GTX Plus 1.5D

A car that came close:

Mahindra XUV3OO W8(O) - due to a lack of rear AC vent and poor boot space, we're not very keen on this despite being a strong contender otherwise. This will be our only steed for a good time to come so we do not want to be in a position that makes us feel disappointed.

Used cars are a strict no from my wife.

The Assessment

I did the test drive for both Nexon and Sonet, both manual. Up until this point, I was mostly clear on getting the Nexon, however, with the test drive things kind of changed.

Important: The Nexon TD vehicle was at 18k on ODO and the SA mentioned that it was due servicing at 15K which wasn't done. He also mentioned that there are issues with clutch and brake pads which are due replacements. There was also a "low" warning on the Nexon TPMS for the left front tyre.


In the performance department, the Sonet clearly felt better than the Nexon. It got up to speeds quickly and found it to have lesser turbo lag than Nexon. However, the Nexon SA mentioned that the lag is due to the clutch problem. I also found the Nexon engine to be very unrefined compared to the Sonet's. Again, the SA mentioned that Nexon is due for servicing and the gravelly engine is due to that. I'm planning to take another TD for the Nexon, but I suppose the Sonet would still win in terms of refinement and overall performance.

Verdict: Sonet > Nexon

Ride handling and dynamics:

The Nexon was quite jiggly/bouncy at low-speed rides but rounded off bumps quite smoothly. No jarring movements on bumps or potholes. I found the steering to be a little too heavy even at low speeds and found it to be strange. I have driven the Nexon BS4 for ~1000km and never found it this way. The SA said the steering is like this - did they change it in the facelift? The Sonet again won this department, although the ride quality on broken roads was jarring due to the stiff suspension. Steering felt light enough for city movements but with reassurance. Couldn't check if the steering weighs up nicely at higher speeds (since we were in city limits) but the SA confirmed that it does.

Verdict: Sonet > Nexon

Interiors and Ergonomics:

The Nexon and Sonet, both, had comfortable seating for the driver and rear seats as well. My wife said that the Sonet had far better interiors, quite obviously. She was also concerned with the cleaning and maintenance of fabric seats on Nexon. The Sonet, since it has ventilated seats, scored far superior to Nexon. My family calls me a polar bear - I start sweating even at regular temperatures for most people and hence, the ventilated seats is a very useful feature for me. Overall practicality of the cabin was also better in the Sonet. For example, there is no place to put your phone in the Nexon (apart from your own pocket - is it for more safety?). But I found it weird that the only spot to keep the phone was that cover for the cup holders - which means we can't have both. Also, the phone wire would cross the gear knob and I found this to be an overall poor design. The small recess near the ports isn't big enough for most smartphones these days. These aspects are much better designed on the Sonet. Another quirk with Nexon was that the gear knob was far too much in the front, such that I'd have to reach for it - but I'm discounting this as I'm sure I'll get used to this in some time.

Verdict: Sonet >> Nexon


Now here is where the tables turn. We don't know for sure how much the Sonet will score if crash-tested, but if we were going with anything that's available as public information about the Korean twins, it is that the structural integrity is poor compared to the Nexon. While I know that the facelifted Nexon hasn't been crash-tested, it can be reasonably assumed that the new car doesn't have too many body changes and hence would score well.

Verdict: Nexon > Sonet

The Confusion

While as per my test drive the Sonet scores higher for both Performance and Handling, I'm not sure if this will hold up because on paper the Nexon has better mechanical fundamentals. I understand that it could be because the Nexon TD vehicle was due to service and requiring a couple of mechanical replacements. However, even if I'm just considering the Sonet individually, its performance and handling satisfied my needs.

This leads me to the real confusion - the Sonet is a clear winner in terms of comfort, whereas the Nexon is a likely winner in terms of safety. In terms of safety equipment though I'm getting more from the Sonet (6 airbags) I understand that airbags alone don't mean anything.

In terms of after-sales support, I'm not sure which would fare better. On one hand, I have Kia which is likely to push me stuff that I don't need and on the other hand, there is TASS which is likely to not do stuff that I push them to do.

Both the dealers agreed to let me do the PDI along with their staff before the VIN registration and final payment, although both of them requested for the down payment to be done at the time of allotment (which I found reasonable - thoughts from BHPians?).

I'm fully confused and my constant bickering about this has made my wife lose her head. She's saying pick anything and be done with it.

Here's what BHPian Kick'OKicks had to say on the matter:

For ₹15 lakhs budget after festival discounts and other usual exchange bonuses, one can get Nissan Kicks Turbo CVT or Turbo MT. If you don't bother about Turbo you may get 1.5 NA XV or XV Premium substantially at lower price points like the ₹11 lakhs range. Kicks is a bigger SUV in the segment, dimension wise though interiors may give you a different perspective, especially the rear seat spacing.

Nissan Kicks doesn't have the Sun Roof and flashy interiors but I feel the 1.5 XV P range has better dual-tone interiors than its top-end variant. The Mercedes engine fitted in the Turbo editions gives you the best ride quality. The I-SPVT intelligent suspension ensures minimal or no body rolls, its safety features like Hill Start Assist, Traction Control, Electronic stability program are very important safety features generally available only in the ₹20-₹22 lakhs variants from other carmakers.

My Kicks Turbo CVT gives me a maximum of 19-21 km/l on Highway if you keep the RPM below 2000 and maintain speed between 80-90. City driving gives me around 13 KMPL maximum. Driving Kicks CVT in the city traffic gives absolute peace of mind by leaving your legs from clutch workings and hands from gear shifting.

My best wishes for you in choosing your best vehicle!!

Here's what BHPian ynike99 had to say on the matter:

Out of the two, I would consider the Sonet. When I made my purchase of Seltos, I had considered all the 4-4.4m cars(Diesel) for the same reason as yours, that I love low-end torque. The engine/gearbox combo of Kia Diesel in both Manual and Auto is something to be experienced. Nexon was on my shortlist right till the top 3 cars(The others were Seltos and Creta Old gen). But somehow after multiple TDs, I could find some fault with all the TD cars. Some niggle/Ergonomic issues etc used to crop up every time, whereas Creta/Kia was pretty consistent throughout.

Regarding Kia on the service front, it's really good to date. Service is timely and proper, Parts are stocked well and it's generally a good experience at a service centre.

Here's what BHPian M5_fan had to say on the matter:

I was in the same boat as you with the requirements being the same except for a petrol engine instead of diesel.

What I recommend you to do is check out the Honda WR-V i-dtec VX. It matches all the requirements that you have stated.

You also get tons of space, Honda reliability and very good dynamics in addition to your list.

What you won't like are:

  • The integrated rear headrests
  • Slight engine noise
  • No rear ac vents (not necessary as the AC is rather good)

Do take a test drive and let us know what you think.

Also, if you are going to choose between Nexon & Sonet only, then I believe safety should get extra marks and hence for that I would choose Nexon.
