The Kia Sportage IV, specifically the facelifted version introduced in 2018, represented a significant step forward for the South Korean automaker in the highly competitive compact SUV segment. This iteration, produced through July 2021, offered a range of engine and drivetrain options, with the 2.4 GDI (Gasoline Direct Injection) paired with an automatic transmission and all-wheel drive being a popular choice for North American buyers. This configuration aimed to balance performance, fuel efficiency, and all-weather capability within the Sportage lineup. It sat as a mid-range offering, positioned above the base 2.0L engine and below the potential for higher trim levels with more luxurious features.

Powertrain & Engine Architecture
At the heart of the 2018-2021 Kia Sportage 2.4 GDI AWD is the Hyundai-Kia G4KJ engine, a 2.4-liter inline-four cylinder gasoline engine. This engine utilizes direct fuel injection (GDI) technology, which improves fuel efficiency and power output compared to traditional port fuel injection systems. The G4KJ boasts a dual continuously variable valve timing (CVVT) system, optimizing valve timing for both intake and exhaust strokes, further enhancing performance and efficiency. The engine produces 184 horsepower at 6000 rpm and 174.8 lb-ft of torque at 4000 rpm. The engine is transversely mounted in the front of the vehicle. Paired with this engine is a six-speed automatic transmission, designed for smooth shifting and efficient power delivery. This transmission was a common choice in Kia and Hyundai vehicles of this era, known for its reliability and responsiveness. The all-wheel-drive system is typically an on-demand system, primarily operating in front-wheel drive to maximize fuel economy, and engaging the rear wheels when traction is lost.
Driving Characteristics
The 2.4 GDI engine, when coupled with the six-speed automatic and AWD system, provides adequate, though not exhilarating, performance. Acceleration from 0-60 mph takes approximately 9.1 seconds. The automatic transmission is tuned for comfort and fuel economy, resulting in relatively smooth gear changes. However, it can sometimes feel hesitant during quick acceleration or when attempting to downshift for passing maneuvers. Compared to the base 2.0L engine, the 2.4 GDI offers a noticeable improvement in power and responsiveness. It doesn’t match the performance of potential turbocharged options available in other markets, but provides a good balance for everyday driving. The AWD system provides enhanced stability and traction in inclement weather conditions, making it a practical choice for regions with snow or rain.
Equipment & Trim Levels
The 2.4 GDI AWD trim typically included a good range of standard features. These commonly included automatic headlights, a rearview camera, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, Bluetooth connectivity, and a suite of driver-assistance features like lane departure warning and automatic emergency braking. Interior upholstery was typically cloth, with available upgrades to leather in higher sub-trims. Optional extras could include a panoramic sunroof, heated and ventilated front seats, a premium audio system, and navigation. The specific feature set varied depending on the package selected.
Chassis & Braking
The Kia Sportage IV utilizes a McPherson strut front suspension and a multi-link rear suspension, providing a comfortable ride quality. The suspension is tuned to prioritize comfort over sporty handling. The AWD models generally feature slightly stiffer springs and dampers compared to front-wheel-drive versions to accommodate the added weight and improve stability. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The braking system is equipped with ABS (Anti-lock Braking System) and electronic brake-force distribution (EBD) for enhanced safety.
Market Reception & Comparison
The 2.4 GDI AWD Sportage was generally well-received by automotive critics. It was praised for its spacious interior, comfortable ride, and comprehensive feature set. However, some reviewers noted that the engine could feel underpowered when fully loaded or driving uphill. Fuel economy was considered average for the class, with combined figures around 27.4 US mpg. Compared to competitors like the Honda CR-V and Toyota RAV4, the Sportage offered a more aggressive styling and a longer warranty, but lacked the same level of refinement and fuel efficiency. The 2.4 GDI offered a good middle ground between the more economical 2.0L and potentially more expensive turbocharged options.
Legacy
The G4KJ engine, while generally reliable, has been subject to some reports of carbon buildup on the intake valves, a common issue with direct injection engines. Regular maintenance, including the use of fuel system cleaners, can help mitigate this issue. The six-speed automatic transmission has proven to be durable and relatively trouble-free. On the used car market, the 2018-2021 Kia Sportage 2.4 GDI AWD remains a popular choice due to its affordability, practicality, and available features. It represents a solid value proposition for buyers seeking a well-equipped and capable compact SUV.
