2017-2018 Kia Stinger GT 3.3 GDI (370 Hp) AWD Automatic

The Kia Stinger GT 3.3 GDI AWD Automatic, produced from 2017 to 2018, represents Kia’s ambitious entry into the performance liftback segment. Positioned as the flagship trim of the first-generation Stinger (KD), this variant aimed to challenge established European sports sedans with a blend of American muscle and Korean value. Built on the rear-wheel-drive-based Kia/Hyundai platform, internally designated as the JH, the Stinger GT sought to redefine Kia’s brand image, moving it beyond its reputation for affordable, practical transportation towards a more dynamic and engaging driving experience. This particular configuration, boasting a twin-turbocharged V6 engine and an eight-speed automatic transmission coupled with all-wheel drive, was the top-tier offering, emphasizing performance and grand touring capabilities.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Stinger GT 3.3 GDI is the Lambda II 3.3-liter twin-turbocharged V6 engine, designated as the G6DP. This engine produces 370 horsepower at 6,000 rpm and 510 Nm (376 lb-ft) of torque between 1,300 and 4,500 rpm. The engine utilizes direct injection, maximizing combustion efficiency and power output. Each cylinder features four valves (DOHC) and is fed by a dedicated twin-scroll turbocharger, minimizing turbo lag and providing a broad torque curve. The engine’s longitudinal mounting allows for a more balanced weight distribution, contributing to improved handling. The eight-speed automatic transmission, sourced from ZF, is a crucial component of the powertrain. It features quick and smooth shifts, and is tuned for both performance and fuel efficiency. The all-wheel-drive system employs a dynamic torque vectoring system, distributing power between the front and rear axles, and even between individual rear wheels, to enhance traction and stability.

Driving Characteristics

The Stinger GT 3.3 GDI delivers a compelling driving experience. The twin-turbo V6 provides strong acceleration, with 0-60 mph times consistently around 4.7-4.9 seconds. The eight-speed automatic transmission is well-matched to the engine’s power delivery, offering responsive shifts in both automatic and manual modes. The all-wheel-drive system provides excellent grip, particularly in adverse weather conditions. Compared to the base 2.0-liter turbocharged four-cylinder Stinger, the GT 3.3 offers significantly more power and torque, resulting in a more engaging and exhilarating driving experience. While the 2.0T prioritizes fuel economy, the GT 3.3 focuses on performance. The GT also feels more planted and stable at higher speeds due to its more robust suspension components and wider tires.

Equipment & Trim Levels

The Stinger GT 3.3 GDI came standard with a comprehensive list of features, including leather upholstery, heated and ventilated front seats, a 7-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a premium sound system, and a suite of advanced safety features such as forward collision warning, automatic emergency braking, and lane keeping assist. Optional extras included a larger 8-inch touchscreen, a head-up display, and Nappa leather upholstery. The interior design was sporty and modern, with a driver-focused layout and high-quality materials. The GT trim also featured unique exterior styling cues, such as a more aggressive front fascia, a rear spoiler, and quad exhaust outlets.

Chassis & Braking

The Stinger GT 3.3 GDI features a fully independent suspension system, with McPherson struts at the front and a multi-link setup at the rear. The suspension is tuned for a balance of comfort and handling, providing a relatively compliant ride while still offering good body control. The GT trim benefits from stiffer springs and dampers compared to lower trims. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The GT also features larger brake rotors and calipers than the base Stinger. The steering is precise and well-weighted, providing good feedback to the driver.

Market Reception & Comparison

The Kia Stinger GT 3.3 GDI was generally well-received by automotive critics. It was praised for its performance, handling, and value. Many reviewers noted that the Stinger offered a compelling alternative to more established European sports sedans. However, some critics pointed out that the Stinger’s fuel economy was not particularly impressive, and that its interior, while well-equipped, lacked the refinement of some of its competitors. Compared to the Stinger 2.0T, the GT 3.3 offered a significant performance upgrade, but at a higher price point and with lower fuel economy. The GT was aimed at buyers who prioritized performance and driving enjoyment over fuel efficiency.

Legacy

The Kia Stinger GT 3.3 GDI, despite its short production run, has established itself as a desirable used car. The G6DP engine, while powerful, has proven to be relatively reliable, although regular maintenance is crucial. The eight-speed automatic transmission has also proven to be durable. The Stinger’s unique combination of performance, style, and value has made it a popular choice among enthusiasts. As the first-generation Stinger fades into the used car market, it is likely to be remembered as a pivotal model for Kia, demonstrating the brand’s ability to compete with established players in the performance car segment.
