The Kia Sonet, particularly the facelifted 2023 model, represents Kia’s entry into the highly competitive subcompact SUV/crossover segment. Introduced in December 2023, the D1.5 CRDi VGT (116 Hp) iMT variant is positioned as a fuel-efficient and technologically equipped option for buyers seeking a practical and affordable vehicle. This specific configuration, combining a diesel engine with Kia’s intelligent Manual Transmission (iMT), aims to balance performance with ease of driving. The Sonet, in its facelifted form, builds upon the original model launched in 2020, offering updated styling, enhanced features, and refined mechanical components.

Powertrain & Engine Architecture
The heart of the Sonet D1.5 CRDi VGT is Kia’s Smartstream 1.5-liter four-cylinder diesel engine. This engine utilizes a common-rail direct injection system, delivering fuel directly into the combustion chamber at extremely high pressure for optimized combustion efficiency and reduced emissions. The Variable Geometry Turbocharger (VGT) is a key component, adjusting the turbine vanes to optimize boost pressure across the engine’s operating range, resulting in improved low-end torque and overall responsiveness. The engine produces 116 horsepower at 4,000 rpm and 250 Nm (184.39 lb-ft) of torque between 1500 and 2750 rpm. The ‘iMT’ (intelligent Manual Transmission) is a 6-speed manual gearbox with a clutch actuator. It eliminates the need for a traditional clutch pedal, offering the convenience of an automatic transmission while retaining the engagement and control of a manual. The system predicts gear changes based on driving patterns and vehicle speed, automatically disengaging the clutch and completing the shift.
Driving Characteristics
The 1.5-liter diesel engine paired with the iMT transmission provides a surprisingly refined driving experience. While not offering the outright acceleration of higher-powered gasoline engines, the Sonet D1.5 CRDi delivers ample torque for everyday driving situations. The iMT transmission contributes to smooth gear changes, particularly in city traffic. The gear ratios are tuned for fuel efficiency, with taller gearing in higher gears to reduce engine speed at highway speeds. Compared to a traditional manual transmission, the iMT offers a less engaging driving experience for enthusiasts, but it significantly reduces driver fatigue. Compared to the gasoline engine options in the Sonet lineup, the diesel variant prioritizes fuel economy and low-end grunt over outright performance.
Equipment & Trim Levels
The Sonet D1.5 CRDi VGT iMT is typically offered in mid-range trim levels. Standard features generally include air conditioning, power windows, power-adjustable side mirrors, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a rearview camera. Safety features such as ABS, dual airbags, and electronic stability control are also standard. Higher trim levels add features like automatic climate control, a larger touchscreen display, a sunroof, and additional safety features like side and curtain airbags. Interior upholstery is typically cloth, with options for leatherette in higher trims. The dashboard layout is modern and functional, with a focus on ease of use.
Chassis & Braking
The Sonet utilizes a front-wheel-drive chassis with a McPherson strut independent suspension in the front and a torsion beam suspension in the rear. This setup provides a comfortable ride quality, absorbing bumps and irregularities in the road surface effectively. The front and rear brakes are both disc brakes, providing adequate stopping power for the vehicle’s weight class. Electric power steering provides light and precise steering feel. The 215/60 R16 tires offer a good balance of grip and ride comfort. The suspension tuning is geared towards comfort rather than sporty handling, prioritizing a smooth and predictable ride.
Market Reception & Comparison
The Kia Sonet has been well-received in markets where it’s offered, particularly in India and other Asian countries. Critics have praised its stylish design, spacious interior, and value-for-money proposition. The D1.5 CRDi VGT iMT variant is often highlighted for its fuel efficiency and ease of driving. Compared to other subcompact SUVs in its class, the Sonet offers a competitive level of features and equipment. The diesel engine provides significantly better fuel economy than the gasoline engine options, making it an attractive choice for drivers who cover long distances. However, the diesel engine may be subject to higher taxes and stricter emissions regulations in some markets.
Legacy
The Kia Sonet, and specifically the 1.5 CRDi VGT iMT powertrain, is still relatively new to the market, so long-term reliability data is still emerging. However, Kia has a reputation for building reliable vehicles, and the Smartstream diesel engine is known for its durability. The iMT transmission, while innovative, is a relatively new technology, and its long-term reliability remains to be seen. In the used car market, the Sonet D1.5 CRDi VGT iMT is expected to hold its value well due to its fuel efficiency and practicality. As the model matures, it is likely to become a popular choice for budget-conscious buyers seeking a reliable and efficient subcompact SUV.
