The compact SUV segment in India has been one of the most hotly contested automotive zones in the last few years. Out of the multitude of options available, Kia Sonet Diesel AT X Line is one model that has carved a distinct niche for itself. With bold styling alongside premium features and a powerful combination of a diesel engine and automatic transmission, the Sonet X-Line offers an enticing mix of practicality, performance, and flair.
How well does it perform in real-life scenarios after months of commutes, long drives on highways, and occasional weekend trips? This long-term review is centered on the ownership experience in terms of performance and comfort, technology and upkeep, and value for money.
The Power and Efficiency of the Diesel Plus Automatic
Powertrain
The Sonet Diesel AT X-Line features a segment-leading 1.5-liter CRDi turbocharged diesel engine which produces 115 PS’s of power along with 250 Nm of torque. This engine is coupled with a 6-speed torque converter automatic transmission which synergizes beautifully with the engine’s characteristics of achieving effortless acceleration and smooth shifts. This is the most powerful and torque dense offering in the segment.
Everyday Use
Over a period of Several months and thousands of kilometers, tested capabilities of the diesel-automatic pairing far exceeded absolutes with effortless engine response while traversing through gridlocked metropolises, performing overtakes on the highways, and when climbing steep hills.
The Senton’s engine provided gratifying torque response across all scenarios. The automatic gearbox logic is well adept for Indian traffic conditions whereby lag is virtually non existent.
Efficiency
As in most cases, opting for the diesel engine variant stems out of a need for reduced costs and higher efficiency. Combined city and highway mileage average between 16 and 18 kmpl while steady cruising at highway speeds allowed the diesel AT X-Line to reach close to 20 kmpl. With a 45-liter fuel tank, range becomes an outstanding 700 kilometers, ideal for long drives and road trips.
Ride, Handling, And Comfort
Suspension And Ride Quality
The Sonet X-Line augments Kia’s trademark well-tuned suspension systems. In daily driving, the ride is comfortable and composed, managing most potholes and speed breakers with relative ease. The sturdiness of the suspension does feel slightly on the firmer side, which aids stability at higher speeds as well as during rapid lane changes. The rear suspension does tend to feel a bit softer when fully loaded with passengers and luggage, and will occasionally bottom out over large road undulations.
Steering and Maneuverability
The Sonet’s urban maneuverability is one of its greater attributes. Steering is light at low speeds, aiding in easy parking and tight turn navigation. With increasing speed, the steering also becomes heavier, instilling confidence at higher speeds on the highway. Excellent outward visibility in addition to the Sonet’s compact dimensions greatly aid in maneuvering through congested city traffic, further improving the overall experience.
Cabin Comfort
The Sonet range’s X-Line variant seats are the most luxurious and they undoubtedly stand out from the rest. The front seats are leatherette, Formula 1-style orthopedically carved, and ventilated to endure scorching Indian summers, making them great for lengthy drives. The steering wheel can be tilted down toward the driver while the driver’s seat can be height-adjusted, ensuring people of all heights can find a comfortable position.
While rear seat comfort is average, two adults can sit comfortably. Although three adults can sit at the back, it can get quite tight on longer road trips. Their USB charging port also ensures back seat passengers are not neglected while the dedicated AC vents keep them cool during the drive.
Features and Technology
Infotainment and Connectivity

Additionally, graphic design and menus are user-friendly, which makes navigation a breeze. To supplement the powerful audio system, Bose speakers furnish punchy sound quality. With the additional 7 speakers, every drive will not only be enjoyable but also make listening to music a whole new experience.
Digital Instrument Cluster
An instrument cluster that is fully digital offers an extensive data set such as fuel consumption, trip history, turn by turn navigation instructions, and many other pieces of information. As with other Kia displays, this one is also bright and easy to read even when the vehicle is exposed to direct sunlight.
Convenience Features
Equally remarkable is the extensive set of convenience features available in the Sonet X-Line. These include:
- Wireless phone charging
- Automatic climate control
- Smart key with push-button start

The high-strength steel structure of the car inspires safety and solid confidence that is enhanced by the feel of the car being very solid and secure at all speeds.
Design and Road Presence
Exterior Styling
The matte graphite paint with X-Line’s specific 16-inch alloy wheels, accented in a dark chrome grille, and black piano highlights set it apart. Sporty orange touches on the skim plates, wheel caps, and brake calipers are also present. Overall, the design is bold and youthful, ensuring the Sonet X-Line captures attention wherever it goes.
Interior Ambiance
The X-Line touch is still present with dark interiors accompanied by orange stitching and metallic trims. Ambient lighting enhances the sense of specialness during night drives. The overall refinement is exceptional for the segment with soft touch materials in crucial areas.
Suitability for Daily Driving and Practicality
Storage Compartment and Boot Space
The Sonet has a boot space of 392 liters which means it can carry shopping bags, a couple of large suitcases, or even weekend luggage. The rear seats have a 60:40 split which enables different configurations for cargo. In-cabin storage features a cooled glovebox, up to four cup holders, and a central armrest with storage bin.
Navigation in an Urban Setting
The Sonet X-Line’s compact footprint, along with its tight turning radius and generous ground clearance, is ideal for bustling city streets. Moreover, the front sensors and 360-degree cameras assist with parking in tight spots as they provide an almost bird-eye view of the vehicle’s surroundings.
Comfort on Long-Distance Drives
On highways, the Sonet Diesel AT X-Line excels. Its engine operates quietly and with minimal vibration, especially at cruising speeds. Moreover, the vehicle feels stable and well-planted even at higher speeds. The vehicle’s cruise control system works without a hitch, and the cabin is equipped with an air purifier, ensuring a comfortable environment during long drives even in heavy traffic or adverse weather.
