The Genesis G90, initially launched as the Hyundai EQ900 in the South Korean market, represents Genesis’s flagship luxury sedan. Introduced for the 2017 model year (2016 in South Korea), the G90 aimed to establish Genesis as a distinct luxury brand separate from Hyundai. This article focuses on the first generation (G90/EQ900 I) specifically equipped with the 5.0 GDi V8 engine paired with an eight-speed automatic transmission and all-wheel drive, produced from 2016 to 2018. This configuration represented the top-tier offering in the G90 lineup, emphasizing performance and refinement.

Technical Specifications

Introduction

The Genesis G90/EQ900 I, launched in 2016, marked a significant step for the Hyundai Motor Group in its ambition to compete with established luxury brands. Positioned above the G80 (formerly Hyundai H900), the G90 offered a more opulent and technologically advanced experience. The 5.0-liter GDi V8 AWD Automatic variant was the range-topping model, designed to deliver both powerful performance and a comfortable, refined ride. It was initially sold as the EQ900 in the Korean domestic market and rebranded as the G90 for international sales, including the United States.

Powertrain & Engine Architecture

At the heart of the G90 5.0 GDi AWD lies the Tau V8 engine, designated as the G8BE. This naturally aspirated 5.0-liter (5038 cc) engine utilizes direct injection (GDi) technology to maximize efficiency and power output. The engine produces 425 horsepower at 6000 rpm and 520 Nm (383.53 lb-ft) of torque at 5000 rpm. The engine features a dual continuously variable valve timing (DCVVT) system and an aluminum block and cylinder heads to reduce weight. The eight-speed automatic transmission, developed in-house by Hyundai, provides smooth and responsive gear changes. 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. The engine also incorporates a Start & Stop system to improve fuel economy during city driving.

Driving Characteristics

The 5.0L V8 G90 delivers a distinctly smooth and powerful driving experience. The engine’s ample torque provides effortless acceleration, making highway merging and overtaking maneuvers easy. While not overtly sporty, the G90 prioritizes a comfortable and composed ride. The eight-speed automatic transmission is well-tuned, offering seamless shifts and contributing to the overall refinement. Compared to the 3.3L twin-turbocharged V6 version, the 5.0L offers a more linear power delivery and a more traditional V8 sound. The all-wheel-drive system provides enhanced grip, particularly in inclement weather, but adds some weight compared to rear-wheel-drive models. The gear ratios are optimized for both cruising efficiency and responsive acceleration, with a focus on providing a relaxed and luxurious driving experience.

Equipment & Trim Levels

The G90 5.0 GDi AWD came generously equipped with standard features befitting a flagship luxury sedan. These included leather upholstery, heated and ventilated front seats with power adjustment and massage functions, a premium sound system (often Lexicon branded), a large infotainment screen with navigation, a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane keeping assist, and automatic emergency braking, and a power-operated rear sunshade. Optional extras included a rear-seat entertainment system, a head-up display, and premium interior trim materials. The interior design emphasized spaciousness and elegance, with high-quality materials and meticulous attention to detail.

Chassis & Braking

The G90 features 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 G90 5.0 GDi AWD is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The electronic stability control (ESC) system and anti-lock braking system (ABS) work in conjunction to enhance safety and control. The steering system is a power-assisted rack-and-pinion setup, offering precise and responsive steering feel. Stabilizer bars are fitted to both the front and rear axles to further reduce body roll during cornering.

Market Reception & Comparison

Critics generally praised the G90 5.0 GDi AWD for its luxurious interior, smooth ride, and powerful engine. However, some reviewers noted that it lacked the brand recognition and prestige of established European luxury rivals. Fuel economy was a common criticism, with the 5.0L V8 consuming a significant amount of fuel, especially in city driving. Compared to the 3.3T V6 model, the 5.0L offered more power and a more refined driving experience, but at the cost of increased fuel consumption and a higher price point. Reliability reports have been generally positive, with owners reporting few major issues with the powertrain.

Legacy

The first-generation Genesis G90/EQ900 established Genesis as a credible contender in the luxury sedan segment. The 5.0 GDi V8 AWD variant, while not the highest-volume seller, remains a desirable option for those seeking a powerful and luxurious flagship sedan. On the used car market, these models hold their value relatively well, particularly those in excellent condition with low mileage. The Tau V8 engine has proven to be a durable and reliable powerplant, and with proper maintenance, these G90s are expected to provide many years of comfortable and refined motoring. The G90 laid the groundwork for Genesis’s continued expansion and its commitment to delivering world-class luxury vehicles.
