Powertrain & Engine Architecture
The heart of this Sorento variant is the G4KJ 2.4-liter inline-four cylinder engine. This engine utilizes Gasoline Direct Injection (GDI) technology, where fuel is injected directly into the combustion chamber, improving efficiency and power output. The G4KJ engine features a dual continuously variable valve timing (CVVT) system, optimizing valve timing for both intake and exhaust to enhance performance across the rev range. The engine produces 188 horsepower at 6000 rpm and 241 Nm (177.75 lb-ft) of torque at 4000 rpm. 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 the era, known for its reliability and responsiveness.
Driving Characteristics
The 2.4 GDI engine, coupled with the six-speed automatic, provides adequate performance for everyday driving. Acceleration from 0 to 60 mph takes around 10 seconds, which is competitive within its class but noticeably slower than the more powerful V6 options available on the Sorento. The automatic transmission is tuned for comfort and fuel economy, with gear changes being smooth and largely unnoticeable. However, it isn’t particularly sporty, and downshifts can sometimes feel hesitant. The all-wheel-drive system provides enhanced traction in inclement weather, making it a suitable choice for regions with snow or rain. The power delivery is linear, making it easy to modulate, but the engine can feel strained when fully loaded or climbing steep hills.
Equipment & Trim Levels
The 2.4 GDI AWD automatic trim typically included a good level of standard equipment. Features commonly found in this variant include air conditioning, power windows and locks, a touchscreen infotainment system with Bluetooth connectivity, a rearview camera, and keyless entry. Higher trim levels added features like leather upholstery, a panoramic sunroof, heated and ventilated front seats, and advanced safety technologies such as blind-spot monitoring and lane departure warning. Interior upholstery was typically cloth on the base trims, with leather options available on higher-spec models. The dashboard layout was functional and well-designed, with a focus on user-friendliness.
Chassis & Braking
The Sorento III 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 all-wheel-drive system adds to the vehicle’s stability and handling capabilities. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) is standard, providing enhanced braking performance and control. The steering is electrically assisted, offering light and precise steering feel.
Market Reception & Comparison
The 2.4 GDI AWD automatic Sorento was generally well-received by critics as a practical and well-equipped family SUV. It offered a good balance of features, fuel economy, and price. Compared to the V6 models, it was less powerful but more fuel-efficient. The 2.0-liter diesel variants, popular in Europe, offered superior fuel economy and torque but came with the potential for higher maintenance costs associated with diesel engines. The 2.4 GDI was often seen as a sweet spot for buyers prioritizing affordability and reliability.
Legacy
The G4KJ engine, while generally reliable, has been known to exhibit some issues with carbon buildup on the intake valves, a common problem 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 dependable. Today, the 2018-2020 Sorento 2.4 GDI AWD automatic represents a good value on the used car market, offering a spacious and well-equipped SUV at a reasonable price. Its blend of practicality, comfort, and all-weather capability continues to make it an appealing choice for families.
