The Genesis G90 II 3.5 T-GDi V6 represents the second generation of Genesis’ flagship sedan, launched in December 2021. Positioned as a luxury competitor to established brands like Mercedes-Benz and BMW, the G90 II aims to deliver a sophisticated driving experience with advanced technology and a focus on rear-seat passenger comfort. This particular variant, equipped with the 3.5-liter twin-turbocharged V6 engine and an eight-speed automatic transmission, serves as the primary powertrain offering for the model in many markets, balancing performance with refinement. It builds upon the foundation of the first-generation EQ900 (as it was known in Korea), significantly upgrading the interior, exterior styling, and technological features.

Powertrain & Engine Architecture
At the heart of the G90 II 3.5 T-GDi is Hyundai’s Smartstream G6DS 3.5-liter twin-turbocharged V6 engine. This engine utilizes direct injection and a sophisticated multi-point injection system to optimize combustion efficiency and power delivery. The twin-turbocharger setup, employing electronically controlled wastegates, provides a broad torque curve, peaking at 530 Nm (390.91 lb.-ft.) between 1300 and 4500 rpm. The engine produces its maximum power output of 380 horsepower at 5800 rpm. The engine is longitudinally mounted in the front of the vehicle, driving the rear wheels. The eight-speed automatic transmission, developed in-house by Hyundai, is designed for smooth and responsive shifting. It features a torque converter lock-up clutch for improved fuel efficiency at cruising speeds. The transmission is programmed with shift-by-wire technology, eliminating the traditional mechanical linkage and contributing to a more refined driving experience.
Driving Characteristics
The 3.5 T-GDi V6 powertrain delivers a compelling blend of performance and comfort. The readily available torque from the twin-turbochargers provides strong acceleration in everyday driving situations. While not overtly sporty, the G90 II offers ample power for confident highway merging and overtaking. The eight-speed automatic transmission contributes to relaxed cruising, with well-chosen gear ratios that keep the engine within its optimal power band. Compared to a potential V8 offering (not currently available in all markets), this variant prioritizes fuel efficiency and a smoother, more refined driving experience. The rear-wheel-drive configuration contributes to balanced handling, although the G90 II is primarily designed for comfortable, rather than aggressive, driving.
Equipment & Trim Levels
The G90 II 3.5 T-GDi typically comes standard with a comprehensive suite of luxury features. Interior appointments include premium leather upholstery, wood trim, and a meticulously crafted dashboard. Standard technology features include a large infotainment touchscreen, a digital instrument cluster, a premium sound system, and a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Optional extras often include a rear-seat entertainment system, massaging seats, and a more advanced sound system. Trim levels generally focus on enhancing the luxury and convenience features, rather than significantly altering the core powertrain or performance characteristics.
Chassis & Braking
The G90 II utilizes a multi-link suspension system at both the front and rear, tuned for a comfortable ride. The suspension geometry is optimized to minimize body roll and provide stable handling. The vehicle is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard safety features. The steering system employs an electric power steering (EPS) system, offering precise and responsive steering feel. Wheel sizes typically range from 19 to 20 inches, depending on the trim level.
Market Reception & Comparison
The Genesis G90 II has been generally well-received by automotive critics, praised for its luxurious interior, advanced technology, and comfortable ride. The 3.5 T-GDi V6 powertrain has been noted for its smooth power delivery and respectable fuel economy. Compared to its competitors, the G90 II often offers a compelling value proposition, providing a similar level of luxury and features at a lower price point. Fuel economy figures of 10.7-11.2 l/100 km (22-21 US mpg) are competitive within the luxury sedan segment. Reliability data is still emerging, but early indications suggest that the Smartstream engine and eight-speed transmission are proving to be durable and dependable.
Legacy
The Genesis G90 II 3.5 T-GDi V6 represents a significant step forward for the Genesis brand, establishing it as a credible competitor in the luxury sedan market. The Smartstream engine and eight-speed automatic transmission are expected to be long-lasting and reliable, providing years of dependable service. As the G90 II matures in the used car market, it is likely to become a sought-after option for buyers seeking a luxurious and technologically advanced sedan at a reasonable price. The focus on rear-seat comfort and refinement positions this variant as a particularly appealing choice for chauffeur-driven executives and discerning passengers.
