    The Sonet is equipped with a 1.5-litre diesel engine that generates 100PS of maximum power and 240Nm of peak torque when paired with the manual transmission. When equipped with the automatic transmission, this engine delivers a maximum power output of 115PS and a peak torque of 250Nm. Since, in both the cases the peak torque does not vary much and it is achieved in the same rpm range -- the everyday performance should not have a major difference between the manual and automatic diesel variant of the Sonet.

    In terms of maximum power, the Sonet’s diesel engine is at par with its rivals, but the XUV300’s diesel engine offers the segment-best peak torque.

    The Sonet is the most fuel efficient diesel-manual car in this segment. However, in case of the automatic transmission, the Sonet’s claimed fuel efficiency is less than that of the Nexon and XUV300 AMT variants.  

    What are The Dimensions of Kia Sonet? 

    The Kia Sonet is a B2 segment SUV, and its overall length is around 4 metres. The Sonet is 20mm wider than the Venue, and its wheelbase is as long as that of the Venue’s. It is the second tallest car in the segment after the EcoSport, and offers the most spacious boot in the segment.

    What are the Variant-wise Features of 2021 Kia Sonet?

    What Are The Features of Kia Sonet HTE Variant? 

    The Sonet diesel’s base variant - HTE is priced at Rs 8.25 lakh. This variant comes with black interior along with fabric seat upholstery. 

    You can check all the key features of the Kia Sonet HTE variant in the table below:

    The HTE covers all the basic safety features, apart from which you also get features like central locking, speed sensing auto door lock, impact sensing auto door unlock, tilt steering, electrically adjustable ORVMs, front power windows, rear AC vents and front and rear USB charger. 

    This base variant lacks some basic features such as an audio system with steering mounted controls, rear power windows and remote central locking. 

    The base HTE is the only variant that comes with the smaller 15-inch steel wheels. 

    What Are The Features of Kia Sonet HTK Variant?

    The Sonet HTK diesel variant is Rs 94,000 more expensive than the base HTE variant.

    This variant doesn’t add-in any other safety feature, but offers an audio system with steering-mounted controls, rear power windows and remote central. With these added features, this variant covers all the basic features. As far as style related features are concerned -- the HTK variant comes with 16-inch steel wheels, which have been styled to look quite similar to alloy wheels, while there is also semi-leather seat upholstery. 

    The Kia Sonet HTK variant’s features are listed in the following table:

    According to our internal data, this variant’s added features do not completely justify the additional premium of Rs. 94,000.

    So, if you go for this variant, then you will be compromising on the value. We’d recommend you to skip the HTK variant and buy HTK+ instead, the reason for which we will provide in the HTK+ variant details.

    What Are The Features of Kia Sonet HTK+ Variant?

    The Kia Sonet HTK+ diesel variant is Rs 50,000 more expensive than the HTK diesel variant.

    In the Sonet’s lineup, modern-day features start from the HTK+ variant onwards, features such as an 8-inch touchscreen infotainment system with wireless Apple CarPlay and Android Auto support. This feature is available in the Sonet only with this system, and not with the bigger 10.25-inch touchscreen that is offered in the higher variants.

    The Sonet HTK+ variant adds-in some important safety features including projector fog lamps, rear defogger, rear parking camera and driver rear view monitor. 

    The other noteworthy additional features include - auto headlamps, turn indicators on ORVMs, roof rails, shark fin antenna, electrically foldable ORVMs and auto AC. 

    All the features that are offered in the Kia Sonet HTK+ variant are listed in the table below:

    Roof Rails


    The additional premium of Rs 50,000 of the HTK+ over the HTK variant’s price is easily justified owing to its useful good-to-have features. Hence, equipment-wise and value-wise the HTK+ is better than the HTK and even the HTE variant. Thus, this is the least variant in the Sonet diesel lineup that you should go for. 

    The HTK+ variant is also available with an automatic transmission option, for which you will need to spend another Rs 90,000. This additional premium is reasonable for an automatic transmission. 

    What Are The Features of Kia Sonet HTX Variant?

    The Sonet HTX diesel variant is Rs 50,000 more expensive than the HTK+ diesel. However, now the HTX diesel’s price crosses the Rs 10 lakh mark, and as it is also a diesel car, it will attract more tax and cess in many states. So, the on-road price difference between these 2 variants will be more than Rs 1 lakh.

    The HTX variant adds-in a handful of features, such as: LED headlamps, sunroof, smart key with push-button start/stop, cruise control, black-beige interior, adjustable rear headrests, rear armrest, leather-wrapped steering and chrome door handles.

    The following table lists all the additional features of the Kia Sonet HTX over the HTK+ variant:

    This variant comes with a sportier visual appeal as compared against the lower variants, but even this doesn’t come with alloy wheels. However, it is not a big miss, as you can retrofit them later. 

    As per our internal data, the HTX variant’s added features actually justify a price increment of around Rs 1.35 lakh. Thus, this variant is a sensible choice in terms of value, but it is not a compelling buy. This is because most of the useful features are covered by the HTK+, except the adjustable rear headrests. So, the HTK+ variant is now our top recommended variant for the diesel version of the Sonet. 

    What Are The Features of Kia Sonet HTX+ Variant? 

    The Kia Sonet HTX+ variant is Rs 1.66 lakh more expensive than the HTX variant.

    The HTX+ is the top variant in the Sonet’s HT Line trim. This variant adds-in a number of features such as - tyre pressure monitoring system, auto-dimming IRVM, 10.25 inch touchscreen infotainment with Bose sound system, ventilated front seats, connected-car tech, air purifier, 16-inch alloy wheels, sound mood lights and digital instrument cluster. 

    You can take a look at all the additional features of the Kia Sonet HTX+ variant over the HTX variant:

    For these additional features, the incremental cost of Rs 1.66 lakh is high and not justified. This variant’s added feel-good features are not so compelling in nature that you can compromise on the value. Hence, between the HTX and HTX+ variants, we would recommend you to choose the HTX. 

    What Are The Features of Kia Sonet GTX+ VARIANT?

    The Sonet GTX+ variant is Rs 34,000 costlier than the HTX+ variant.

    Apart from these sporty styling features, the GTX+ variant offers a bunch of other safety features, including - 6 airbags, electronic stability control, hill start assist, traction control and front parking sensors. The GTX+ is the only variant in the Sonet range that offers wireless phone charger.

    HTX ke baad GTX+ variant Sonet diesel ka second most value-for-money variant hai. So agar aap ek feature-rich Sonet lena chahte hain -- not just in terms of functionality, but safety as well -- aur aapka budget iss variant pe stretch karna allow karta hai -- toh aap iss variant pe upgrade kar sakte hain. 

    After the HTX, the GTX+ is the second best value-for-money variant in the Sonet line-up. 

    The GTX+ variant is also available with an automatic transmission option, for which you will need to spend an additional is Rs 90,000. After the HTK+, the GTX+ is the second automatic variant in the Sonet diesel range, and is Rs 2.5 lakh more expensive than the former. As per our internal data, this variant justifies the incremental cost over HTK+ automatic. So, if you can afford it, then surely you can choose to buy the GTX+ variant for its extra safety as well as convenience features.

    Kia Sonet Diesel - Which Variant To Buy? 

    In the Kia Sonet diesel range, HTK+ variant is our top recommendation for the prospective buyers. The HTK+ variant covers mostly all the must-have features along with some good-to-have features and it also doesn’t compromise on the value. 

    If you don’t wish to spend for the good-to-have features, then you can choose to buy the HTK variant, but in this case you will be compromising on the value.

    Above the HTK+ variant, the HTX and GTX+ variants are worthy to consider buying in terms of value. The additional key features of the HTX such as the smart key w/ push-button start/stop, cruise control, LED headlamps, adjustable rear headrests and sunroof, make this variant worth its asking price with good value. 

    Also Read - Sonet 1.2 Petrol vs Diesel - Should You Buy The Kia Sonet Diesel?

    The GTX+ variant is a good buying option, primarily owing to its added safety features like side and curtain airbags, auto-dimming IRVM, electronic stability control, hill start assist and tyre pressure monitoring system. Apart from these, the other desirable features of this variant include an audio system and ventilated front seats to make it a properly loaded small car.

    When the Sonet diesel-automatic is concerned, there are only two options available -- the HTK+ and GTX+ variants. The HTK+ gets most of the basic features, while choosing the GTX+ is sensible in terms of value. Choose any one of these two variants as per your budget. We can only say that the long term ownership will be certainly more satisfactory with the GTX+ variant.
