About the Kia Sonet
Design and Aesthetics
The Kia Sonet’s exterior design is one of its strongest selling points, exuding a bold and contemporary vibe that appeals to a wide audience. The Signature Tiger Nose Grille is flanked by sleek LED headlamps and fang-shaped DRLs, giving it a fierce and modern appearance. The 2024 facelift introduced sharper lines, a revised bumper, and connected LED tail lamps, aligning its look with Kia’s newer models like the Seltos. The X-Line variant takes this a step further with its exclusive Matte Graphite finish and sporty crystal-cut alloy wheels, enhancing its road presence. Measuring 3995 mm in length, the Sonet adheres to the sub-4-meter category, making it tax-friendly in India, while its 1790 mm width and 1642 mm height ensure a commanding stance.
Inside, the cabin feels premium for its segment, with soft-touch materials, a well-laid-out dashboard, and a dual-tone color scheme in higher trims. The 10.25-inch touchscreen infotainment system dominates the center console, paired with a matching digital driver display in top variants, offering a tech-savvy experience. Features like ventilated front seats, a Bose sound system, and ambient lighting elevate the Sonet’s interior to near-luxury levels, setting it apart from competitors like the Maruti Suzuki Brezza, which leans more utilitarian.
Performance and Driving Experience
The Sonet’s trio of engines caters to varied driving needs. The 1.2L petrol is the entry-level option, delivering 81.8 bhp and 115 Nm of torque through a 5-speed manual. It’s ideal for city commutes, offering a silent and refined operation with an ARAI-claimed mileage of 18.4 kmpl. However, it lacks the punch for spirited driving or heavy highway use. The 1.0L turbo petrol, with 118 bhp and 172 Nm, steps up the game, available with a 6-speed iMT (clutchless manual) or a 7-speed DCT. This engine strikes a balance between efficiency (up to 19.2 kmpl) and performance, with a responsive mid-range that makes overtaking effortless. The DCT variant, in particular, offers smooth gear shifts and paddle shifters for added control, though some users report a slight lag in aggressive driving scenarios.
For those prioritizing torque and fuel economy, the 1.5L diesel is the standout, producing 114 bhp and a robust 250 Nm. Available with a 6-speed manual or a 6-speed automatic, it delivers exceptional highway mileage (up to 24.1 kmpl) and a refined driving experience. The diesel automatic is notably smooth, with seamless gear changes and ample low-end grunt for tackling inclines or heavy loads. Ride quality across all variants is comfortable, with a slightly stiff suspension that absorbs potholes well in the city but can feel bouncy at higher speeds. The Sonet’s handling is predictable, though its thick C-pillars slightly compromise rear visibility.
Features and Technology
The Kia Sonet is a feature-packed SUV, often outshining its rivals in this department. Even the base HTE variant comes with six airbags, ABS, and rear parking sensors, emphasizing safety. Mid-tier trims like HTK+ add a sunroof, LED DRLs, and an 8-inch touchscreen with Android Auto and Apple CarPlay. Higher variants like HTX and above introduce ADAS Level 1 features—such as lane keep assist and forward collision warning—making the Sonet one of the few in its segment with such advanced tech. The GTX+ and X-Line trims top the range with a 360-degree camera, ventilated seats, wireless charging, and a premium Bose 7-speaker system.
Connectivity is a strong suit, with Kia’s UVO Connect offering remote engine start, geofencing, and real-time vehicle tracking. The digital cluster provides customizable displays, enhancing the driver’s interaction with the car. However, some features, like cruise control, are absent in lower trims, and the rear bench is best suited for two adults due to limited shoulder room, a common trait in this segment.
Safety and Reliability
Safety is a priority for the Sonet, with a standard fitment of six airbags across all variants—a rare feat in the sub-compact SUV category. Additional safety features include electronic stability control (ESC), hill start assist, and tire pressure monitoring (in higher trims). The inclusion of ADAS in top variants adds a layer of proactive safety, though its effectiveness in India’s chaotic traffic conditions remains a topic of debate. While the Sonet hasn’t been crash-tested by Global NCAP yet (as of March 2025), its robust build and extensive safety kit suggest a strong safety profile. Kia also boasts the lowest maintenance costs in the segment—16% lower for petrol and 14% lower for diesel, per Frost & Sullivan research—along with a high residual value, making it a reliable long-term investment.
Market Positioning and Ownership Experience
Priced between ₹8 lakh and ₹15.70 lakh (ex-showroom), the Sonet straddles the line between affordability and premium appeal. Its wide variant spread ensures accessibility for budget buyers while offering luxury features for those willing to spend more. Kia’s extensive dealership network and excellent after-sales service further enhance the ownership experience, with service costs comparable to mass-market brands like Maruti Suzuki. The Sonet’s warranty of 3 years/unlimited kilometers adds peace of mind, though spare parts can occasionally be pricier than competitors due to Kia’s imported components.
Close Competitors
The Kia Sonet operates in a crowded segment, facing stiff competition from established players. Here’s how it compares to its closest rivals:
Hyundai Venue
The Hyundai Venue, a corporate cousin to the Sonet, shares similar engines (1.2L petrol, 1.0L turbo petrol, 1.5L diesel) and a feature-rich approach. Priced slightly lower (starting at ₹7.94 lakh ex-showroom), the Venue offers a sunroof and cruise control in mid-spec trims, which the Sonet reserves for higher variants. However, the Sonet edges ahead with ADAS, a larger touchscreen, and a more premium cabin feel. The Venue’s ride is softer, appealing to comfort seekers, while the Sonet’s stiffer setup favors stability.
Maruti Suzuki Brezza
The Maruti Suzuki Brezza dominates sales with its reliability and fuel efficiency (up to 20.1 kmpl petrol). Priced from ₹8.34 lakh, it offers a single 1.5L petrol engine with manual or automatic options. The Brezza lacks the Sonet’s turbo petrol or diesel choices and advanced features like ADAS or ventilated seats, but its softer suspension and extensive service network make it a practical choice for rural and semi-urban buyers. The Sonet, in contrast, targets urban buyers with its tech and style.
Tata Nexon
The Tata Nexon (starting at ₹8 lakh) is a safety champion, boasting a 5-star Global NCAP rating. It offers petrol (1.2L turbo) and diesel (1.5L) engines with manual, AMT, and DCT options. The Nexon’s strengths include a spacious cabin and rugged build, but its interior quality and feature list lag behind the Sonet’s. The Sonet counters with superior refinement, ADAS, and a more modern design, though the Nexon’s lower price and safety credentials are hard to ignore.
Mahindra XUV 3XO
The Mahindra XUV 3XO, a refreshed XUV300, starts at ₹7.49 lakh and brings a 1.2L turbo petrol (up to 130 bhp) and a 1.5L diesel to the table. It matches the Sonet with features like a panoramic sunroof and a 10.25-inch touchscreen but lacks ADAS. The XUV 3XO offers a punchier drive and competitive pricing, though its sales lag behind the Sonet’s due to Mahindra’s narrower urban reach. The Sonet’s smoother automatics and premium appeal give it an edge.
Verdict Against Competitors
The Kia Sonet stands out for its blend of style, technology, and variety, appealing to buyers who value a premium experience. It outshines the Venue and Brezza in features and refinement, matches the Nexon’s versatility while surpassing it in cabin quality, and competes closely with the XUV 3XO’s performance but with a stronger brand presence. However, its higher top-end pricing and slightly firm ride may deter budget-focused or comfort-first buyers.
Final thoughts!
The Kia Sonet is a compelling choice in the sub-compact SUV segment, offering a rare combination of bold design, advanced technology, and flexible powertrain options. From its base HTE variant to the luxurious X-Line, it caters to a wide audience, balancing affordability with premium aspirations. Its technical prowess—highlighted by the efficient 1.5L diesel, punchy 1.0L turbo, and feature-loaded cabin—makes it a strong contender against the Hyundai Venue, Maruti Suzuki Brezza, Tata Nexon, and Mahindra XUV 3XO. While it excels in urban environments with its smooth transmissions and safety features, potential buyers should weigh its slightly stiff ride and premium pricing against competitors’ strengths. For those seeking a stylish, tech-savvy, and reliable SUV under ₹20 lakh, the Sonet is a worthy investment, backed by Kia’s growing reputation in India.
