In a world where automotive luxury has long been synonymous with a handful of venerable names, it’s increasingly rare for a newcomer to not just challenge the status quo, but to redefine it entirely. For decades, the script has been predictable: German precision, British heritage, or Japanese meticulousness. But what happens when a brand, relatively young by luxury standards, quietly unveils a flagship experience that forces even the most jaded enthusiast to sit up and take notice? That question leads us directly to the Twenty Twenty Three Genesis G Ninety, a vehicle that doesn’t merely compete, but rather embodies a fascinating philosophy about what modern luxury truly means. Is this the most underrated luxury sedan right now? A deep dive into its design, engineering, and driving dynamics suggests it might very well be, proving that true refinement can emerge from unexpected corners.
Background & Heritage
The story of Genesis as a standalone luxury brand is a relatively recent chapter in automotive history, yet its roots stretch back further than many realize. Hyundai, the parent company, first experimented with a premium offering in 2008 with the original Genesis sedan. This car, later known as the Genesis G80 after the brand’s official launch, was a revelation, offering exceptional value and an undeniable taste of luxury. However, it was truly in 2015 that Genesis shed its parental umbrella, emerging as an independent luxury marque with a clear vision: to disrupt the established order by focusing on thoughtful design, advanced technology, and a customer-centric experience. This move signaled a serious commitment to challenging titans like Mercedes-Benz, BMW, and Audi, not just on price, but on intrinsic quality and desirability.
The G90, as the flagship of this nascent brand, carries a significant burden of expectation and serves as the ultimate expression of Genesis’s design philosophy, “Athletic Elegance.” Its predecessor, the EQ900 (known as G90 in North America) launched in 2015, immediately showcased Genesis’s intent to deliver a full-size luxury experience. It was a commendable first effort, establishing a solid foundation for comfort and refinement. The 2023 Genesis G90, however, represents a quantum leap, a complete reimagining that firmly plants the brand’s flag in the ultra-luxury segment. This second-generation model isn’t just an evolution; it’s a declaration, showcasing a maturity and confidence that belies the brand’s youth, proving that genuine luxury isn’t solely built on decades of tradition, but can also be forged through relentless innovation and a fresh perspective.
The development of the 2023 G90 involved a global team, drawing talent from design studios in Germany, the U.S., and Korea, marrying European sophistication with Korean technological prowess and an understanding of the American luxury market. Key figures like Luc Donckerwolke, Genesis’s Chief Creative Officer, have been instrumental in shaping the brand’s distinctive visual identity. The G90 embodies this “Athletic Elegance” through its striking Two-Line lighting signature, parabolic lines, and a massive, intricately designed Crest Grille that projects undeniable presence. Every crease, every panel gap, and every surface of the G90 has been meticulously sculpted to convey a sense of understated power and refined grandeur, distinguishing it from the often-overstated designs of some competitors. This careful attention to detail in its lineage and design philosophy is critical to understanding how Genesis, and specifically the G90, has managed to carve out such a compelling niche in the highly competitive luxury sedan market.
Furthermore, Genesis’s approach to luxury transcends mere aesthetics and performance; it delves into the very essence of the ownership experience. From the initial concept, the G90 was conceived not just as a mode of transport, but as a sanctuary, a statement of sophisticated taste. This ethos is particularly evident in its commitment to advanced safety features, intuitive technology, and a cabin environment designed for ultimate tranquility. The brand understands that for many discerning buyers, true luxury is about effortlessness, about anticipating needs, and about providing an escape from the relentless pace of modern life. By focusing on these often-overlooked aspects, the Genesis G90 aims to build a loyal following among those who value innovation and a fresh interpretation of premium automotive ownership, rather than simply relying on badge prestige. Its relatively short heritage is quickly being filled with a narrative of disruption and progressive luxury.
Engineering & What’s Under The Hood
At the heart of the 2023 Genesis G90’s formidable luxury experience lies a meticulously engineered powertrain designed for effortless refinement rather than raw, jarring power. Unlike some competitors that offer a multitude of engine options, Genesis has opted for a streamlined, potent lineup that perfectly aligns with the G90’s comfort-oriented philosophy. The primary engine for the G90 is a sophisticated 3.5-liter Twin-Turbocharged GDI (Gasoline Direct Injection) V6. This powerplant, internally known as the T-GDI, delivers a robust 375 horsepower at 5,800 rpm and a substantial 391 lb-ft of torque available from a low 1,300 rpm all the way up to 4,500 rpm. This broad torque band ensures that power is always on tap, providing smooth, linear acceleration without ever feeling strained, whether cruising on the highway or navigating city streets.
For those seeking an even greater measure of performance and technological sophistication, Genesis offers a more advanced version of this 3.5L V6, bolstered by an innovative 48V Electric Supercharger (e-S/C). This Electrified Supercharger doesn’t just add power; it virtually eliminates turbo lag, providing instantaneous throttle response and an even silkier power delivery. With the e-S/C, the output climbs to an impressive 409 horsepower at 5,800 rpm and 405 lb-ft of torque, available slightly higher at 2,000 rpm, maintaining that wide, accessible peak until 4,500 rpm. This mild-hybrid system not only enhances performance but also subtly contributes to efficiency, demonstrating Genesis’s commitment to integrating cutting-edge technology that elevates the driving experience without compromising on the flagship’s serene character. Both engines are paired with a butter-smooth 8-speed automatic transmission, renowned for its imperceptible shifts and optimal gear ratios, perfectly complementing the G90’s luxurious demeanor.
Power is delivered to all four wheels via Genesis’s standard HTRAC All-Wheel Drive system, which intelligently distributes torque between the front and rear axles depending on driving conditions, enhancing stability and traction in diverse environments. The G90’s chassis is a masterpiece of engineering, employing a multi-link suspension system at both front and rear, which is then augmented by the Genesis Adaptive Control Suspension with Road Preview. This groundbreaking system utilizes a forward-facing camera to scan the road ahead, preemptively adjusting the damping forces of the electronically controlled suspension to absorb imperfections before the car even reaches them. The result is an astonishingly smooth and composed ride, isolating occupants from the harsh realities of imperfect pavement, a truly remarkable feat in the pursuit of ultimate comfort.
Beyond the powertrain and suspension, the 2023 G90 features a host of engineering marvels designed to create its unparalleled cabin experience. The body structure itself is incredibly rigid, utilizing advanced high-strength steels and aluminum, which not only contributes to dynamic stability but also forms a robust foundation for exceptional noise, vibration, and harshness (NVH) suppression. This is further bolstered by extensive sound-deadening materials, acoustic laminated glass for all windows (including the rear), and active noise cancellation technology that uses microphones and speakers to counteract unwanted frequencies. The braking system, featuring large ventilated discs (e.g., 14.5-inch front, 13.6-inch rear), provides confident and progressive stopping power, engineered to bring the substantial sedan to a halt with composure. Every component, from the electric power steering system tuned for light yet precise feel to the advanced ADAS suite, is meticulously integrated to deliver an experience that feels both effortlessly luxurious and technologically advanced, setting a new benchmark for what a flagship sedan can offer.
Behind the Wheel: Performance & Experience
Driving the 2023 Genesis G90 is less about conquering the road and more about gliding over it, cocooned in a sanctuary of calm and composure. The moment you settle into the meticulously crafted driver’s seat, adjustable in what feels like an infinite number of ways and offering both heating and ventilation, you understand the G90’s primary mission: unparalleled comfort and refinement. The twin-turbo V6, whether in its standard form or with the electrified supercharger, delivers power with an almost imperceptible eagerness. There’s no dramatic surge, no jarring kick; instead, a smooth, linear wave of torque propels the G90 forward with an effortless grace that belies its substantial size. Overtaking maneuvers on the highway are executed with confidence, the engine humming quietly in the background, never intruding on the cabin’s tranquility.
The steering, a crucial component in any driving experience, is perfectly weighted for a luxury sedan. It’s light enough for easy maneuvering in tight urban environments but firms up subtly at higher speeds, providing just enough feedback to keep the driver engaged without ever feeling nervous or overly sporty. This balance perfectly complements the G90’s character, ensuring precision when needed but prioritizing relaxation above all else. What truly sets the G90 apart, however, is its revolutionary Genesis Adaptive Control Suspension with Road Preview. This system is a game-changer, reading the road ahead and preparing the suspension to absorb imperfections before they are encountered. The result is a ride quality that borders on magical, filtering out bumps, potholes, and expansion joints with an uncanny ability, creating an almost surreal sense of detachment from the outside world. It feels as if the G90 is floating just above the asphalt, transforming even the most battered roads into a smooth carpet.
Beyond the primary driving dynamics, the overall experience within the G90 is one of meticulous attention to detail and thoughtful integration of technology. The cabin is an oasis of high-quality materials, from the buttery Nappa leather upholstery and genuine open-pore wood trim to the exquisite forged carbon elements. Ergonomics are superb, with physical controls for essential functions complementing the intuitive 12.3-inch infotainment touchscreen. Advanced Driver-Assistance Systems (ADAS) work seamlessly in the background, providing a safety net without being intrusive. Features like Highway Driving Assist 2, Remote Smart Parking Assist 2, and the innovative Fingerprint Authentication System enhance convenience and confidence, reinforcing the G90’s status as a technologically forward-thinking flagship.
The experience isn’t solely for the driver; rear passengers are treated to an executive-class environment. The long-wheelbase variant, specifically, offers expansive legroom and a suite of amenities including power-adjustable, massaging, heated, and ventilated seats. A dedicated 8-inch touchscreen controller in the rear armrest puts control over climate, seating, and entertainment at their fingertips, transforming the back seat into a truly luxurious mobile office or relaxation lounge. The integration of a Bang & Olufsen 3D Premium Audio system, with its 23 speakers, creates an immersive soundstage, further isolating occupants in a cocoon of auditory delight. Every aspect of the G90’s interior and driving dynamics is orchestrated to deliver a singular, sophisticated experience: one of profound comfort, serene composure, and undeniable presence, making every journey a luxurious escape rather than just a drive.
Enthusiast Angle: Mods, Community & Aftermarket
While the Genesis G90 isn’t typically the first car that comes to mind when discussing aftermarket modifications or a vibrant tuning scene, its unique position as an understated luxury powerhouse offers a distinct enthusiast angle. Owners of the G90, much like those of other high-end luxury sedans, often seek to personalize their vehicles in ways that enhance its inherent qualities rather than dramatically altering them. The focus isn’t on track days or quarter-mile times, but on refining elegance, subtly improving performance, and making an already exclusive vehicle even more bespoke. This involves a carefully curated selection of upgrades that complement the G90’s sophisticated character, appealing to an enthusiast who values discernment over flash.
Performance enhancements for the G90’s 3.5-liter twin-turbo V6, especially the version with the electric supercharger, primarily revolve around ECU tuning. Reputable tuners can unlock additional horsepower and torque with software recalibrations, capitalizing on the robust engine architecture. While extreme gains might not be the goal, an extra 30-50 horsepower and similar torque figures can sharpen throttle response and provide an even more authoritative surge when needed, without compromising the car’s smooth power delivery. Owners might also explore subtle exhaust upgrades, opting for systems that offer a slightly deeper, more refined growl under acceleration but remain hushed at cruising speeds, maintaining the cabin’s serene environment. High-flow air filters or cold air intakes could provide marginal gains while adding a touch of under-hood flair, appealing to the enthusiast who appreciates optimized engine breathing.
Aesthetic and handling modifications often focus on enhancing the G90’s already commanding presence. Aftermarket wheel choices are popular, with owners opting for larger diameter, lighter forged wheels from brands like Vossen, BBS, or HRE. These not only contribute to a more aggressive stance but can also reduce unsprung weight, subtly improving handling dynamics. Pairing these with high-performance luxury tires, such as Michelin Pilot Sport 4S or Pirelli P Zero, can further sharpen steering response and grip. For a sportier posture, discreet lowering springs from companies like Eibach or H&R might be considered. These typically reduce ride height by an inch or so, minimizing wheel gap and giving the G90 a more planted, performance-oriented look without sacrificing too much of its acclaimed ride comfort, especially with the adaptive suspension.
The G90 community, though perhaps smaller than those for sportier Genesis models like the G70, is a growing collective of discerning owners who appreciate the brand’s unique blend of luxury and value. Online forums, social media groups, and dedicated Genesis owner clubs serve as platforms for sharing experiences, discussing potential upgrades, and showcasing personalized builds. These communities often focus on detailing tips, advanced technology discussions, and subtle aesthetic modifications such as chrome deletes, window tinting, or bespoke interior accents. For the G90 enthusiast, the aftermarket isn’t about transforming the car into something it’s not; it’s about meticulously refining what it already is – an exceptional, understated luxury sedan that offers a canvas for sophisticated personalization, allowing owners to subtly differentiate their flagship without sacrificing its core essence of elegance and comfort.
How It Compares
In the rarefied air of the full-size luxury sedan segment, the 2023 Genesis G90 faces off against some of the most storied names in automotive history: the Mercedes-Benz S-Class, BMW 7 Series, Audi A8, and Lexus LS. These are the benchmarks, the standard-bearers against which all newcomers are measured. Yet, the G90 doesn’t just hold its own; it carves out a compelling niche by offering a truly distinctive proposition that challenges the very definition of premium value. While its German rivals boast decades of established prestige and often more extensive personalization options, the G90 counters with a fresh perspective on luxury, an undeniably striking design, and an incredibly robust standard feature set that often costs extra in its European counterparts.
Compared to the Mercedes-Benz S-Class, often considered the gold standard, the G90 offers a ride quality that is remarkably close in terms of isolation and comfort, especially with its predictive air suspension. The S-Class still holds an edge in sheer brand cachet and perhaps the ultimate in interior opulence and infotainment depth, but the G90’s cabin, with its exquisite materials and unique design, feels equally special and arguably more intuitive in some areas. Against the BMW 7 Series, the G90 emphasizes serene comfort over aggressive sportiness, a distinction that many luxury buyers increasingly prioritize. While the 7 Series offers a more engaging, driver-focused experience, the G90 excels in its ability to effortlessly whisk occupants away from the stresses of the road, and its exterior styling is arguably less polarizing than BMW’s recent design language.
The Audi A8, with its minimalist interior and sophisticated Quattro all-wheel drive, is another formidable rival. The G90 matches the A8 in technological prowess, particularly with its advanced driver-assistance systems and digital displays. Where the G90 truly distinguishes itself is in its emotional appeal and interior ambiance; its design feels warmer and more inviting than the A8’s often starkly modern aesthetic. The Lexus LS, a long-standing Japanese contender, shares the G90’s focus on refinement and reliability, but the Genesis brings a more contemporary design language and a slightly more dynamic, though still very comfortable, driving feel. The G90 feels less constrained by tradition, offering a bolder statement of luxury than the often conservative LS.
Perhaps the most significant differentiator for the 2023 Genesis G90 is its extraordinary value proposition. While its starting price places it firmly in the premium luxury segment, it often undercuts comparably equipped S-Class, 7 Series, or A8 models by a substantial margin, sometimes tens of thousands of dollars. This isn’t achieved through compromise; rather, Genesis packages an incredible array of standard features—from the adaptive suspension and all-wheel drive to the full suite of advanced safety tech and luxury amenities—that are typically expensive options on its rivals. This “more for your money” approach, combined with a comprehensive warranty and a unique concierge-style ownership experience, makes the G90 not just a competitive alternative but a truly compelling choice. It demonstrates that the pinnacle of luxury no longer demands an exorbitant premium solely for a badge, but can be found in a meticulously crafted vehicle that redefines expectations, proving itself a prince among cars even against established royalty.
The Quiet Ascent of a New Icon
The 2023 Genesis G90 stands as a definitive statement from a brand that is rapidly maturing into a serious contender in the ultra-luxury segment.

What truly solidifies the G90’s position as potentially the most underrated luxury sedan right now is its ability to deliver this profound level of refinement and technological sophistication at a value point that forces a re-evaluation of the entire segment. It challenges the long-held belief that true luxury must come with an exorbitant price tag, proving that a brand doesn’t need a century of heritage to produce an automotive masterpiece. Instead, Genesis leverages intelligent design, cutting-edge technology, and a deep understanding of what discerning buyers truly desire: comfort, composure, and a sense of effortless prestige. The G90 represents a significant leap forward not just for Genesis, but for the luxury market as a whole, indicating a shift towards a more meritocratic landscape where quality and experience increasingly trump historical pedigree alone.
The Genesis G90’s meticulous interior, a masterclass in ergonomics and material selection, further solidifies its status. Every touchpoint, from the tactile switchgear to the supple leather and genuine wood trim, exudes quality and thoughtful design. The suite of advanced driver-assistance systems and the intuitive infotainment setup are not just technological marvels; they are seamlessly integrated tools that enhance safety and convenience without overwhelming the driver. Moreover, the focus on the rear passenger experience, particularly in the long-wheelbase variant, elevates the G90 beyond a mere driver’s car, positioning it as a legitimate chauffeured executive vehicle, ready to pamper and impress from any seat within its acoustically isolated cabin. This holistic approach to luxury, considering every facet of the ownership and occupancy experience, is a hallmark of the G90’s brilliance.
Ultimately, the 2023 Genesis G90 is more than just a strong competitor; it’s a trailblazer.
