July 2022 - Kia Sonet Diesel Variants Explained - Which One To Buy?

In this variant explained article, you'll find out which variant of the Kia Sonet diesel you should buy based on the ex-showroom prices, variant-wise features and value for money. Here we compare and objectively analyse the Sonet's diesel variants and the features to figure out which variant is worth buying for a good value for money and ownership experience. Then we will compare the engine specs, dimensions and mileage of the Kia Sonet with its competitors and other diesel-powered B2-segment SUVs like Hyundai Venue, Tata Nexon, Mahindra XUV300 and Honda WRV.

 

Kia Sonet

Updated: This update of the Kia Sonet variants explained includes buying recommendations based on the July 2022 prices along with engine and dimension comparison with the new Venue facelift diesel.

What Are The Pros And Cons Of Kia Sonet Diesel?

The pros or advantages of the Kia Sonet diesel are:

  • Option of a diesel engine with a manual as well as an automatic transmission even as diesel engines become a dying breed
  • Best-in-class mileage figure of 24.1kmpl with the diesel-manual
  • The diesel engine carries a nominal premium of Rs. 40,000 over the turbo petrol-ACMT and Rs. 60,000 over turbo petrol-DCT automatic
  • A fairly long list of features for the top variant includes - ventilated seats, sunroof, auto AC, auto-dimming inside mirror, front and rear armrests, premium Bose sound system with woofer, tyre pressure sensors, 6 airbags, LED headlamps, LED DRLs and rear window sunshades
  • With the diesel engine, the HTX variant offers phenomenal value for money for diesel-manual and diesel-automatic buyers

The Kia Sonet diesel has the following shortcomings or problems:

  • Inefficient torque converter automatic transmission’s fluid coupling brings the official ARAI mileage figure down to just 19kmpl, which is the worst in the class
  • The base variant misses out on several must-have features while the higher HTK offers poor value for money; thus no variant below Rs. 10.0 lakh offers a decent balance of value and features
  • Rear washer wiper is reserved for top variant while rear armrest, LED headlamps, DRLs, sunroof and cruise control are only available in the HTX and higher variants

Compared to the Sonet 1.2L normal petrol engine, the diesel variants cost Rs. 1.30 lakh to Rs. 1.74 lakh more. While it may sound like a steep price jump, the diesel engine also offers substantially more power and torque. Compared to the turbo petrol engine, the diesel-manual variants of the Sonet only cost about Rs. 40,000 more. The diesel-automatic range costs Rs. 60,000 more and adds some more power and torque to the equation on top of the diesel-manual’s performance figures.

Should You Buy Sonet Petrol Or Diesel?

Compared to the 1.2L normal petrol engine, the turbo diesel engine will recover the higher upfront cost in 85,000km adn 1,13,000km depending on the variant you pick. Our in house algorithm tells us that the diesel engine justifies Rs. 1.12 lakh price jump with better performance alone. With that in mind, the diesel engine will recover the remaining higher upfront cost in 12,000km to 40,000km depending on the variant.

Compared to the 1.0L turbo petrol engine, the 1.5L turbo diesel engine will recover the higher upfront cost in 25,000km to 28,000. According to our in-house algorithm, factoring in the performance advantages of the diesel engine and the ACMT convenience of the turbo petrol engine, it only needs to recover about Rs. 20,000. You can expect to recover this amount by driving the Sonet diesel for about 15,000km.

Note: There may be some feature differences between comparable petrol and diesel variants. For example, the Sonet HTK Plus petrol gets a sunroof but the HTK Plus diesel does not.

If you’re considering the Sonet turbo petrol automatic and turbo diesel automatic, then the mileage advantage of the diesel engine goes down significantly. This is because of the inefficient fluid coupling of the torque converter automatic transmissions. So, you’ll have to drive the Sonet diesel for a little over 50,000km to recover the higher upfront cost.

Kia Sonet Diesel HTE - Base Model Features

HTE

The base HTE variant of the 2022 Sonet diesel costs Rs. 8.89 lakh and it’s only available with the manual transmission. The Sonet offers the following notable features as standard in the base model:

The HTK variant seems reasonably loaded for a decent ownership experience. However, our in-house algorithm suggests that it’s quite a bit overpriced considering the additional features and the incremental cost over the HTE variant. So, budget buyers should either buy the lower HTE variant and personalise it with aftermarket accessories or stretch the budget to get a higher variant, which offers better value for money.

  • Halogen projector fog lamps
  • Rear defogger
  • Rear camera
  • 8-inch touchscreen with Android Auto and Apple Carplay
  • 2x tweeters
  • Wireless phone charging

The HTK Plus variant offers a decent value for money and almost entirely justifies the incremental cost over the base model. But it has an ex-showroom price of more than Rs. 10.0 lakh, which will effectively impact the on-road prices in several states as it falls in the higher registration tax slab. So, if you’re ready to consider a Rs. 10.0 lakh+ variant, then we’ll suggest stretching your budget a bit more and buying the higher HTX variant. It will offer significantly better value for money and a far better ownership experience too.

It is the most VFM variant of the Sonet diesel and our top recommendation as it offers enough must-have and good-to-have features to satisfy most B2 diesel SUV buyers. This recommendation also holds for the diesel-automatic buyers, who enjoy an even better value score with the HTX variant.

Kia Sonet Diesel HTX Plus vs GTX Plus Variant

GTX Plus

The top-spec Kia Sonet GTX Plus diesel gets manual as well as automatic transmission and costs Rs. 12.85 lakh with the manual and Rs. 13.69 lakh with the automatic. It’s only Rs. 36,000 pricier than the HTX Plus manual while the automatic is another Rs. 84,000 more expensive. It gets only cosmetic features like red accents inside and outside, GT Line badges, black interior and black leather upholstery.

Since this is a cosmetic upgrade over the HTX Plus trim, Sonet diesel-manual buyers should decide for themselves if they want the unique style features of the GTX Plus variant. Sonet automatic buyers don’t have the option of the HTX Plus variant. So, the Sonet GTX Plus diesel-automatic is suitable for those who want the automatic transmission without sacrificing on the upmarket ownership experience.

Which Variant Of The Kia Sonet Diesel Should You Buy?

With the diesel-manual powertrain, the base HTE variant lacks several must-have features while the next HTK variant offers very poor value for money. So, we’ll suggest budget buyers to just go with the base HTE variant and personalise it with accessories. If you can stretch your budget, then the HTK Plus may seem like a good option value-wise, but it’s not the one we’d recommend. It costs just over Rs. 10.0 lakh, so it’ll also end up costing a fair bit more because of the higher registration costs in many states.

We’ll suggest you stretch your budget a little more and buy our top recommended HTX variant. It offers almost all must-have features along with a tremendous value for money. Going up the price ladder, the HTX Plus and GTX Plus are decent options and worth considering if you want their features.

What Are The Engine Specifications Of The Kia Sonet Diesel?

The Sonet is a rare diesel car in its class with an upmarket torque converter automatic transmission while its rivals either offer a simpler AMT or don’t have an automatic transmission at all. It has a class-leading mileage figure of 24.1kmpl. However, with the inefficient torque converter automatic transmission, its mileage figure drops to worst-in-class 19kmpl. Otherwise, its power and torque figures are acceptable for a B2-segment diesel SUV.

What Are The Dimensions Of The Kia Sonet?

Against other B2-segment diesel SUVs, the Sonet stands out with a respectable ground clearance, width and boot space. Besides the boot space and height, it has nothing worth bragging about but it strikes a nice balance in its dimensions and doesn’t falter in any way.
