The Hyundai Tucson III, specifically the facelifted model released in 2018, represented a significant step forward for Hyundai’s popular compact SUV. The 2.4 GDI (Gasoline Direct Injection) variant, producing 181 horsepower and paired with an automatic transmission and all-wheel drive (AWD), occupied a key position in the Tucson lineup as a well-rounded option appealing to buyers seeking a balance of performance, features, and capability. Produced from 2018 through 2020, this configuration aimed to provide a comfortable and capable driving experience for families and individuals alike. It built upon the foundation of the TL platform (internally designated as HX10), offering a more refined and technologically advanced package compared to its predecessors.

Powertrain & Engine Architecture
The heart of the 2018-2020 Tucson 2.4 GDI AWD was the Hyundai G4KJ engine, a 2.4-liter inline-four cylinder powerplant. This engine utilized direct fuel injection (GDI) technology, which injected fuel directly into the combustion chamber, improving efficiency and power output compared to traditional port fuel injection systems. The G4KJ featured a double overhead camshaft (DOHC) valvetrain with Hyundai’s D-CVVT (Dual Continuous Variable Valve Timing) system, optimizing valve timing for improved performance across the engine’s operating range. The engine produced 181 horsepower at 6000 rpm and 174.8 lb-ft of torque at 4000 rpm. This power was delivered through a six-speed automatic transmission, branded as “SHIFTRONIC,” which offered a manual shift mode for greater driver control. The transmission was specifically tuned to work with the engine’s torque curve, providing smooth and responsive shifts.
Driving Characteristics
The 2.4 GDI automatic combination offered a comfortable and predictable driving experience. While not a performance-oriented setup, it provided adequate acceleration for everyday driving situations, including highway merging and passing. The automatic transmission, while smooth, wasn’t particularly quick to downshift, which could be noticeable when needing a burst of power. Compared to the available manual transmission, the automatic offered convenience but sacrificed some responsiveness. The AWD system provided enhanced traction in inclement weather conditions, making it a suitable choice for regions experiencing snow or rain. The gear ratios were optimized for fuel efficiency and cruising comfort, rather than outright acceleration.
Equipment & Trim Levels
The 2.4 GDI AWD trim typically came well-equipped, often positioned as a mid-range offering within the Tucson lineup. Standard features generally included air conditioning, power windows and locks, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a rearview camera, and a suite of safety features like ABS, electronic stability control, and multiple airbags. Higher trim levels added features such as leather upholstery, a panoramic sunroof, heated front seats, and advanced driver-assistance systems like blind-spot monitoring and rear cross-traffic alert. Interior upholstery was typically cloth on the base trims, with leather options available on higher-spec models. Dashboard configurations were consistent across the 2.4 GDI models, featuring a user-friendly layout with intuitive controls.
Chassis & Braking
The Tucson III utilized a McPherson strut front suspension and an independent multi-link rear suspension. This setup provided a comfortable ride quality while maintaining reasonable handling characteristics. The front suspension incorporated a coil spring and anti-roll bar to reduce body roll during cornering. Braking duties were handled by ventilated discs at the front and solid discs at the rear. The ABS (Anti-lock Braking System) was standard, enhancing braking performance and stability, particularly on slippery surfaces. Steering was rack-and-pinion with electric power steering, providing a light and responsive feel.
Market Reception & Comparison
The 2018-2020 Hyundai Tucson 2.4 GDI AWD was generally well-received by automotive critics. It was praised for its spacious interior, comfortable ride, and comprehensive feature set. Fuel economy was considered average for its class, achieving around 21 mpg city and 28 mpg highway. Compared to the base 2.0-liter engine, the 2.4 GDI offered a noticeable performance improvement. The 2.4 GDI was often seen as a more practical choice than the sportier, but less fuel-efficient, options available from competitors like the Honda CR-V or Toyota RAV4. Reliability was generally good, although some owners reported minor issues with the GDI fuel injection system requiring occasional cleaning.
Legacy
The Hyundai Tucson III 2.4 GDI AWD has proven to be a relatively reliable and durable vehicle in the used car market. The G4KJ engine, while not without its minor quirks, has generally held up well over time with proper maintenance. The availability of affordable parts and a strong dealer network contribute to its continued appeal. The combination of all-wheel drive, a comfortable interior, and a reasonable price point makes it a popular choice for buyers seeking a practical and dependable compact SUV. As of today, well-maintained examples continue to command reasonable prices, reflecting the Tucson’s reputation for value and longevity.
