The Genesis G90, initially launched as the Hyundai EQ900 in the South Korean domestic market, represents Genesis’s flagship luxury sedan. Introduced for the 2017 model year (2016 in Korea), the G90 aimed to establish the Genesis brand as a serious competitor to established German and Japanese luxury marques. This article focuses on the first generation (G90/EQ900 I) specifically equipped with the 3.3T GDi V6 engine paired with an eight-speed automatic transmission and all-wheel drive, produced from 2016 to 2018. This configuration occupied the mid-range position in the G90 lineup, offering a balance between performance and efficiency compared to the range-topping 5.0L V8.

Powertrain & Engine Architecture
The heart of this G90 variant is the Lambda II 3.3-liter twin-turbocharged V6 engine, designated as the G6DP. This engine utilizes direct injection (GDi) technology, injecting fuel directly into the combustion chamber for improved efficiency and power. The twin-scroll turbochargers, coupled with an intercooler, minimize turbo lag and provide a broad torque curve. The engine produces 370 horsepower at 6000 rpm and 510 Nm (376 lb-ft) of torque between 1300 and 4500 rpm. This power is delivered through a smooth-shifting, eight-speed automatic transmission, which is specifically tuned for refined operation and efficient power delivery. The all-wheel-drive system employs a multi-plate clutch to distribute torque between the front and rear axles, enhancing traction and stability in various driving conditions.
Driving Characteristics
The 3.3T AWD G90 offers a comfortable and composed driving experience. While not as overtly sporty as some of its European rivals, the engine provides ample power for effortless highway cruising and confident passing maneuvers. The eight-speed automatic transmission is well-programmed, offering smooth gear changes and responsive downshifts. The all-wheel-drive system provides enhanced grip, particularly in inclement weather. Compared to the base 3.8L naturally aspirated V6, the 3.3T offers significantly more performance. It also provides a more refined experience than the larger 5.0L V8, which, while more powerful, can feel less balanced due to its weight distribution. The gear ratios are optimized for both fuel efficiency and acceleration, with a focus on providing a relaxed and refined driving experience.
Equipment & Trim Levels
The 3.3T G90 typically came well-equipped with standard features including leather upholstery, heated and ventilated front seats, a premium audio system, a large infotainment screen with navigation, and a suite of advanced safety technologies such as automatic emergency braking, lane departure warning, and adaptive cruise control. Optional extras included a rear-seat entertainment system, a heads-up display, and upgraded leather trim. Interior color options typically included black, beige, and gray. The dashboard layout is clean and modern, with a focus on intuitive controls and a luxurious ambiance. The trim level generally sat between the base model and the top-tier 5.0L V8, offering a compelling combination of features and performance.
Chassis & Braking
The G90 utilizes a multi-link suspension system at all four corners, tuned for a comfortable ride. The suspension geometry is optimized to minimize body roll and provide stable handling. The 3.3T models typically featured ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard features. Stabilizer bars are fitted to both the front and rear axles to further reduce body roll during cornering. The chassis is designed to provide a quiet and refined ride, with extensive sound insulation to minimize road and wind noise.
Market Reception & Comparison
Critics generally praised the G90 for its luxurious interior, comfortable ride, and generous features list. The 3.3T engine was considered a good balance between performance and fuel economy. However, some reviewers noted that the G90 lacked the brand cachet of its European competitors. Fuel economy figures were respectable for a large luxury sedan, but not class-leading. Compared to the 5.0L V8, the 3.3T offered a more manageable fuel consumption without sacrificing a significant amount of performance. Reliability reports have been generally positive, with few major issues reported for this powertrain combination.
Legacy
The first-generation Genesis G90, particularly the 3.3T AWD variant, established the brand as a viable contender in the luxury sedan segment. The Lambda II engine proved to be a reliable and durable powerplant, and the eight-speed automatic transmission has also demonstrated good long-term reliability. On the used car market, these G90s offer a compelling value proposition, providing a significant amount of luxury and features for the price. While maintenance costs may be slightly higher than some domestic brands, the G90’s overall reliability and build quality have earned it a positive reputation among owners. The G90 laid the foundation for Genesis’s continued expansion and its commitment to delivering world-class luxury vehicles.
