The Genesis G90, initially launched as the Hyundai EQ900 in the South Korean domestic market, represents Genesis’s first foray into the luxury sedan segment. Introduced for the 2017 model year (2016 in Korea), the G90 aimed to challenge established German and Japanese luxury brands. This article focuses on the first generation (G90/EQ900 I) equipped with the 3.8-liter GDi V6 engine paired with an eight-speed automatic transmission, produced from 2016 to 2018. This configuration served as the entry point into the G90 lineup, offering a balance of performance and value within the broader range of available powertrains.

Powertrain & Engine Architecture
The heart of this G90 variant is the Lambda II 3.8-liter V6 engine. This naturally aspirated engine utilizes direct gasoline injection (GDi) technology to enhance fuel efficiency and power output. The Lambda II engine family is a mainstay of Hyundai/Kia/Genesis powertrains, known for its relatively smooth operation and durability. The engine employs a dual overhead camshaft (DOHC) valvetrain with continuously variable valve timing (CVVT) on both intake and exhaust sides, optimizing performance across the rev range. The 3.8 GDi produces 315 horsepower at 6,000 rpm and 292.81 lb-ft of torque at 5,000 rpm. This power is channeled through a smooth-shifting, eight-speed automatic transmission, designed to provide both responsive acceleration and comfortable cruising. The transmission features a wide gear ratio spread, contributing to both fuel economy and performance.
Driving Characteristics
The 3.8L V6 automatic G90 delivers a comfortable and refined driving experience, prioritizing smoothness over outright sportiness. Acceleration is adequate for most driving situations, with the eight-speed transmission providing quick and seamless shifts. Compared to the available 5.0L V8, the 3.8L offers less raw power, resulting in a slightly slower 0-60 mph time. However, the V6 provides sufficient power for highway merging and passing maneuvers. The automatic transmission is tuned for relaxed cruising, with gear changes often imperceptible. While paddle shifters are not standard, the transmission allows for manual gear selection. The rear-wheel-drive configuration contributes to balanced handling, although it doesn’t offer the all-weather capability of an all-wheel-drive system.
Equipment & Trim Levels
The 3.8 GDi V6 Automatic trim typically served as the base model for the G90. Standard features included leather upholstery, heated and ventilated front seats, a premium audio system, a large infotainment touchscreen 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 panoramic sunroof, and upgraded leather trim. The interior design emphasized luxury and spaciousness, with high-quality materials and meticulous attention to detail. The dashboard layout was clean and intuitive, with a focus on user-friendliness.
Chassis & Braking
The G90 features a robust chassis designed for comfort and stability. The suspension utilizes a multi-link setup at all four corners, providing a smooth and controlled ride. The suspension tuning is geared towards absorbing bumps and minimizing body roll. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard features, enhancing safety and control. The G90’s weight, ranging from 1995 to 2050 kg (4398.22 – 4519.48 lbs.), is substantial, but the suspension and braking systems are well-matched to handle the vehicle’s mass.
Market Reception & Comparison
Critics generally praised the first-generation G90 for its luxurious interior, comfortable ride, and comprehensive suite of features. The 3.8L V6 Automatic variant was seen as a good value proposition, offering a significant amount of luxury for the price. However, some reviewers noted that the V6 engine lacked the effortless power of the V8. Compared to its German rivals, the G90 offered a more competitive price point, but it didn’t quite match the brand prestige of established luxury brands. Fuel economy was average for the segment, with combined fuel consumption ranging from 11.8 to 12.2 l/100 km (19.9 – 19.3 US mpg). The 3.8L engine generally proved to be reliable, with fewer reported issues compared to the more complex V8 powertrain.
Legacy
The Genesis G90/EQ900 I 3.8 GDi V6 Automatic has established itself as a reliable and comfortable luxury sedan in the used car market. The Lambda II V6 engine is known for its longevity, and the eight-speed automatic transmission has proven to be durable. While not as sought-after as the V8-powered models, the 3.8L variant offers a compelling combination of value, comfort, and reliability. The G90’s introduction marked a significant step forward for the Genesis brand, demonstrating its commitment to challenging the established luxury car market. Today, these early G90s represent an affordable entry point into the world of luxury motoring, offering a refined driving experience and a generous array of features.
