2018 Kia Quoris II 3.3 T-GDI V6 (365 Hp) AWD Automatic

The Kia Quoris II 3.3 T-GDI V6 AWD Automatic represents a significant step forward for Kia’s flagship sedan, introduced in 2018. Building upon the original Quoris (known as the K9 in some markets), the second generation aimed to compete more directly with established luxury brands. This particular variant, equipped with the twin-turbocharged 3.3-liter V6 engine and all-wheel drive, positioned itself as the performance-oriented option within the Quoris II lineup, offering a blend of power, technology, and refinement. Production continued with updates until the model was discontinued in several markets, including the US, in 2020. The Quoris II was primarily targeted towards markets where large, comfortable sedans with a strong feature set were highly valued.

Powertrain & Engine Architecture

The heart of the Quoris II 3.3 T-GDI is the Lambda II 3.3-liter twin-turbocharged V6 engine. This engine, designated as the G6DC, utilizes direct injection and a sophisticated dual-scroll turbocharger system to deliver both high power and responsive torque. The engine benefits from Kia’s Dual Continuous Variable Valve Timing (D-CVVT) technology, optimizing valve timing for improved efficiency and performance across the rev range. The 8-speed automatic transmission, sourced from ZF, is a crucial component of this powertrain. It provides smooth and quick shifts, contributing to the car’s refined driving experience. The transmission is programmed for both comfort and performance, with selectable drive modes influencing shift points. The all-wheel-drive system employs a multi-plate clutch to distribute torque between the front and rear axles, enhancing traction and stability, particularly in adverse weather conditions.

Driving Characteristics

The 365 horsepower and 376 lb-ft of torque produced by the 3.3 T-GDI engine translate into brisk acceleration. While not a sports sedan, the Quoris II delivers confident passing power and a composed highway cruising experience. The 8-speed automatic transmission is well-matched to the engine’s characteristics, providing seamless gear changes. Compared to the naturally aspirated 3.8-liter V6 offered in some markets, the turbocharged 3.3 T-GDI provides a noticeable increase in performance. The all-wheel-drive system enhances grip and stability, particularly on slippery surfaces, making it a more sure-footed vehicle than rear-wheel-drive alternatives. The steering is light and precise, though it lacks the ultimate feedback found in more focused performance sedans. The suspension is tuned for comfort, absorbing bumps and imperfections in the road effectively.

Equipment & Trim Levels

The Quoris II 3.3 T-GDI AWD Automatic typically came well-equipped, reflecting its positioning as a luxury vehicle. Standard features often included leather upholstery, heated and ventilated front seats, a premium audio system, a large touchscreen infotainment system with navigation, and a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane departure warning, and blind-spot monitoring. Optional extras could include a rear-seat entertainment system, a panoramic sunroof, and upgraded interior trim materials. The interior design emphasized spaciousness and comfort, with a focus on high-quality materials and a refined aesthetic. The dashboard layout was clean and intuitive, with a central touchscreen dominating the center console.

Chassis & Braking

The Quoris II utilizes a robust chassis with an independent McPherson strut suspension at the front and an independent multi-link suspension at the rear. This suspension setup provides a comfortable ride while maintaining good handling characteristics. Ventilated disc brakes are fitted on all four wheels, providing ample stopping power. The anti-lock braking system (ABS) and electronic stability control (ESC) are standard features, enhancing safety and control. The steering system employs an electric power steering (EPS) unit, offering precise and responsive steering feel. The all-wheel-drive system adds to the vehicle’s stability and traction, particularly in challenging driving conditions.

Market Reception & Comparison

The Kia Quoris II 3.3 T-GDI AWD Automatic received generally positive reviews from automotive critics. It was praised for its spacious interior, comfortable ride, and generous list of standard features. The turbocharged V6 engine was also well-regarded for its performance and refinement. However, some critics noted that the Quoris II lacked the brand cachet of established luxury rivals. Compared to other vehicles in its class, such as the Lexus ES, Acura RLX, and Buick LaCrosse, the Quoris II offered a compelling value proposition, providing a similar level of features and performance at a lower price point. Fuel economy was respectable for a vehicle of its size and performance, but not class-leading.

Legacy

The Kia Quoris II, while not a massive sales success, represented a significant step forward for the brand in terms of design, technology, and overall quality. The 3.3 T-GDI V6 engine proved to be a reliable and capable powertrain, and the 8-speed automatic transmission contributed to a smooth and refined driving experience. In the used car market, the Quoris II 3.3 T-GDI AWD Automatic offers a compelling value for buyers seeking a spacious, well-equipped, and comfortable luxury sedan. While long-term reliability data is still emerging, early indications suggest that the powertrain is generally durable, with proper maintenance. The Quoris II paved the way for Kia’s continued expansion into the luxury segment, demonstrating the brand’s ability to compete with established players.
