The Genesis G90L I (facelift, introduced in 2018) represents a significant iteration of Hyundai’s luxury flagship sedan, initially known as the Hyundai EQ900 in its domestic Korean market. This extended-wheelbase version, designated the “L,” was primarily aimed at discerning buyers prioritizing rear passenger comfort and prestige. Production of this specific facelift model ran from 2018 through December 2021. The G90L I, particularly when equipped with the 5.0-liter GDi V8 engine and all-wheel drive, positioned itself as a direct competitor to established luxury sedans from European and Japanese manufacturers, such as the BMW 7 Series, Mercedes-Benz S-Class, and Lexus LS. This variant represented the top-of-the-line offering in the G90L range, emphasizing performance and a refined driving experience alongside its spacious interior.

Powertrain & Engine Architecture
The heart of the G90L I 5.0 GDi is the Tau V8 engine, specifically the G8BE code. This naturally aspirated 5.0-liter engine utilizes direct injection (GDi – Gasoline Direct Injection) technology to maximize combustion efficiency and power output. The engine features 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 8-speed automatic transmission, sourced from ZF, is a crucial component of this powertrain. It’s known for its smooth shifts and wide gear ratio spread, contributing to both comfortable cruising and responsive acceleration. 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 425 horsepower and 383 lb-ft of torque delivered by the 5.0L V8, coupled with the eight-speed automatic and AWD, provide a compelling driving experience. While not overtly sporty, the G90L I offers brisk acceleration, capable of reaching 60 mph in around 5.3 seconds. The automatic transmission is tuned for smoothness and refinement, prioritizing comfortable shifts over aggressive downshifts. Compared to the available 3.3L twin-turbo V6, the V8 provides a more linear power delivery and a richer exhaust note. The AWD system provides confident handling in inclement weather, but the car’s substantial weight (over 5,000 lbs) is noticeable during spirited driving. The extended wheelbase of the “L” variant contributes to a remarkably smooth and isolated ride quality, particularly beneficial for rear passengers.
Equipment & Trim Levels
The G90L I 5.0 GDi AWD typically came generously equipped. Standard features included leather upholstery, heated and ventilated front and rear seats, a premium sound system (often Lexicon branded), a large infotainment touchscreen with navigation, and a suite of advanced driver-assistance systems (ADAS) such as adaptive cruise control, lane keeping assist, and automatic emergency braking. The interior featured wood trim and aluminum accents, creating a luxurious ambiance. Optional extras included a rear-seat entertainment system, massaging seats, and a power-adjustable steering wheel. The G90L I was positioned as the flagship trim, offering the highest level of luxury and technology available in the G90 lineup.
Chassis & Braking
The G90L I utilizes a multi-link suspension system at all four corners, designed to provide a comfortable and controlled ride. The suspension is electronically controlled, allowing for adjustments to damping rates based on driving conditions. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The ABS (Anti-lock Braking System) is standard, along with electronic stability control and traction control. Due to the vehicle’s weight, brake fade can occur under extreme or repeated hard braking. The steering is power-assisted and offers a comfortable weight, though it lacks the direct feel of some European competitors.
Market Reception & Comparison
Critics generally praised the G90L I 5.0 GDi AWD for its luxurious interior, comfortable ride, and powerful engine. However, some reviewers noted that the car’s styling was conservative and lacked the visual flair of its rivals. Fuel economy was also a common criticism, with the combined fuel consumption of 16.9 US mpg being relatively high for a luxury sedan. Compared to the 3.3T models, the V8 offered superior refinement and a more traditional luxury car experience, but at the cost of fuel efficiency. The V8 also commanded a higher price tag. Reliability reports have been generally positive, with owners reporting few major issues.
Legacy
The Genesis G90L I 5.0 GDi AWD represents a pivotal moment for the Genesis brand, demonstrating its ambition to compete with established luxury automakers. While the model has been superseded by newer generations of the G90, the 5.0L V8 variant remains a desirable option in the used car market, particularly for buyers seeking a comfortable, well-equipped, and powerful luxury sedan. The Tau V8 engine, while not the most fuel-efficient, is known for its durability and smooth operation. As a used vehicle, the G90L I offers a significant value proposition, providing a level of luxury and performance comparable to its European rivals at a lower price point. The car’s relatively complex systems, however, may require specialized maintenance, and parts availability could become a concern in the long term.
