2016-2018 Genesis G90EQ900 I 3.8 GDi V6 (315 Hp) AWD Automatic

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 3.8-liter GDi V6 engine producing 315 horsepower, paired with an eight-speed automatic transmission and all-wheel drive. Production of this configuration ran from 2016 to 2018.

Technical Specifications

INTRODUCTION

The Genesis G90/EQ900 I, launched in 2016, was the first model to fully embody the newly established Genesis brand identity. Positioned as a direct competitor to the Lexus LS, BMW 7 Series, and Mercedes-Benz S-Class, the G90 aimed to deliver luxury and refinement at a more accessible price point. The 3.8 GDi V6 AWD Automatic variant occupied the middle ground in the initial G90 lineup, offering a balance between performance and fuel efficiency compared to the range-topping 5.0L V8 model. It was designed to appeal to buyers seeking a comfortable and well-equipped luxury sedan without the outright performance of the V8.

Powertrain & Engine Architecture

At the heart of the G90 3.8 is Hyundai’s Lambda II 3.8-liter naturally aspirated V6 engine, designated G6DJ. This engine utilizes direct gasoline injection (GDi) technology to enhance fuel efficiency and power output. The engine produces 315 horsepower at 6000 rpm and 292.81 lb-ft of torque at 5000 rpm. The Lambda II engine features a dual continuously variable valve timing (CVVT) system, optimizing valve timing for improved performance across the rev range. The engine is longitudinally mounted in the front of the vehicle.

The engine is mated to a smooth-shifting eight-speed automatic transmission, developed in-house by Hyundai. This transmission offers a wide range of gear ratios, contributing to both fuel efficiency and responsive acceleration. The all-wheel-drive system is full-time, utilizing a multi-plate clutch to distribute power between the front and rear axles as needed, enhancing traction and stability in various driving conditions. The system doesn’t have selectable modes, operating automatically based on sensor inputs.

Driving Characteristics

The 3.8L V6-powered G90 delivers a comfortable and refined driving experience. While not as overtly powerful as the 5.0L V8, the 315 hp engine provides ample power for everyday driving and highway cruising. Acceleration is smooth and linear, with the eight-speed automatic transmission seamlessly shifting through the gears. The all-wheel-drive system provides confident handling in all weather conditions. Compared to the V8, the 3.8 feels slightly less urgent in acceleration, but the difference is noticeable primarily during aggressive driving. The automatic transmission is tuned for comfort, prioritizing smooth shifts over sporty responsiveness. The gear ratios are optimized for highway efficiency, with a relatively tall final drive.

Equipment & Trim Levels

The G90 3.8 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. Available options 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 elegant, with a focus on user-friendliness. The trim level generally sat between the base model and the luxury trim, offering a good balance of features and price.

Chassis & Braking

The G90 rides on a double-wishbone front suspension and a multi-link rear suspension, providing a comfortable and controlled ride. The suspension is tuned for comfort, absorbing bumps and imperfections in the road with ease. The G90 3.8 utilizes 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 reduce body roll during cornering. The rear suspension on some models featured air suspension for an even smoother ride.

Market Reception & Comparison

Critics generally praised the G90 for its luxurious interior, comfortable ride, and generous features list. The 3.8L V6 engine was considered adequate for most drivers, although some reviewers noted that it lacked the punch of the V8. Fuel economy was generally considered average for a large luxury sedan. Compared to its rivals, the G90 offered a compelling value proposition, providing similar levels of luxury and technology at a lower price point. The 3.8L variant was often seen as the sweet spot in the lineup, offering a good balance of performance, fuel economy, and price. Reliability reports have been generally positive, with few major issues reported.

Legacy

The first-generation Genesis G90 established the brand as a legitimate contender in the luxury sedan segment. The 3.8L GDi V6 engine, while not the most powerful option, proved to be a reliable and efficient powerplant. On the used car market, these G90s represent a good value for buyers seeking a well-equipped and comfortable luxury sedan. Maintenance costs are generally comparable to other luxury brands, although parts availability may be slightly more limited than for more established marques. The G90’s success paved the way for the second-generation model, which further refined the brand’s luxury offering.
