INTRODUCTION
The 2018-2020 Kia Sorento facelift built upon the success of the third-generation model, introduced in 2015. The facelift brought revised styling, upgraded technology, and refinements to the powertrain options. The 3.3 GDI V6 Automatic represented the top-tier offering, designed for buyers prioritizing performance and a premium driving experience. Positioned above the 2.4L four-cylinder and 2.0L turbocharged options, it catered to those needing extra power for towing, hauling passengers, or simply enjoying a more spirited drive. The Sorento, in general, aimed to bridge the gap between smaller crossovers and larger, more expensive SUVs, offering a compelling value proposition with its generous standard features and long warranty.
Powertrain & Engine Architecture
At the heart of the Sorento 3.3 GDI is Kia’s Lambda II V6 engine, specifically the G6DH code. This 3.3-liter naturally aspirated engine utilizes Gasoline Direct Injection (GDI) technology, which improves fuel efficiency and power output by injecting fuel directly into the combustion chamber. The engine features a double overhead camshaft (DOHC) valvetrain with continuously variable valve timing (CVVT) on both intake and exhaust valves, optimizing engine performance across the rev range. The eight-speed automatic transmission, sourced from Hyundai (which owns Kia), provides smooth and responsive shifting. This transmission features a wide gear ratio spread, contributing to both fuel efficiency and acceleration. The Sportmatic mode allows drivers to manually select gears for greater control. The engine’s design prioritizes refinement and drivability over outright peak power, making it well-suited for everyday driving and long road trips.
Driving Characteristics
The 3.3 GDI V6 Automatic Sorento delivers a noticeably more confident and relaxed driving experience compared to the lower-powered engine options. With 290 horsepower and 252 lb-ft of torque, acceleration is brisk, and the engine feels capable in most driving situations. The eight-speed automatic transmission is well-tuned, providing smooth gear changes and keeping the engine in its optimal power band. While not a sports SUV, the Sorento V6 offers ample power for merging onto highways, overtaking slower vehicles, and tackling inclines. The front-wheel-drive configuration provides adequate traction in most conditions, although all-wheel drive was available as an option. Compared to the turbocharged 2.0L, the V6 offers a more linear power delivery and a more traditional engine sound. The automatic transmission, while refined, doesn’t offer the same level of engagement as a manual transmission, but it prioritizes convenience and ease of use.
Equipment & Trim Levels
The 3.3 GDI V6 Automatic typically came equipped with a high level of standard features. These generally included leather upholstery, heated and ventilated front seats, a large touchscreen infotainment system with navigation, a premium sound system, a panoramic sunroof, and a suite of advanced driver-assistance systems (ADAS) such as automatic emergency braking, lane departure warning, and adaptive cruise control. Optional extras could include a rear-seat entertainment system, upgraded leather trim, and a surround-view monitor. Trim levels varied by market, but generally, the V6 engine was reserved for the highest trim levels, offering a luxurious and well-equipped experience.
Chassis & Braking
The Sorento III utilizes a McPherson strut front suspension and a multi-link rear suspension, providing a comfortable and controlled ride. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The braking system consists of ventilated discs at the front and solid discs at the rear. Anti-lock brakes (ABS) and electronic stability control (ESC) are standard features, enhancing safety and stability. The steering is electrically assisted, providing a light and responsive feel. The suspension tuning is geared towards comfort, prioritizing a smooth ride over sporty handling. The weight of the V6 engine does contribute to a slightly higher curb weight compared to the four-cylinder models, but the suspension is adequately tuned to handle the added weight.
Market Reception & Comparison
The Kia Sorento 3.3 GDI V6 Automatic was generally well-received by automotive critics. Reviewers praised its powerful engine, smooth transmission, spacious interior, and long list of standard features. Fuel economy was a common criticism, as the V6 engine consumes more fuel than the smaller engine options. Compared to competitors like the Honda Pilot, Toyota Highlander, and Ford Explorer, the Sorento offered a compelling value proposition, often undercutting its rivals in price while offering similar levels of equipment and performance. The V6 engine provided a noticeable performance advantage over the base four-cylinder engine, making it a popular choice for buyers who frequently tow trailers or drive in mountainous terrain.
Legacy
The Lambda II V6 engine, in general, has proven to be a reliable and durable powerplant. While some early GDI engines experienced carbon buildup issues, Kia addressed these concerns with software updates and improved fuel injector designs. The eight-speed automatic transmission has also proven to be relatively reliable. On the used car market, the 2018-2020 Kia Sorento 3.3 GDI V6 Automatic holds its value reasonably well, particularly models with low mileage and a clean maintenance history. Its combination of power, space, and features continues to make it an attractive option for families seeking a versatile and dependable SUV.
