      The 2026 Genesis G90 is frequently referred to as a more affordable option compared to the BMW 7 Series and Mercedes-Benz S-Class, but its most intriguing feature is not its lower price point. The true appeal of the G90 lies in its dual identity—the interface embodies the sleek, high-contrast aesthetic of an iPhone app, while the driving experience recalls traditional luxury cars. We're not just referring to a smooth and quiet ride; the G90 is exceptionally plush.

      While it offers a pleasant driving experience, it should not be considered a “driver’s car.” Instead, it functions as a limousine that also provides enjoyment for the passenger. Its driving dynamics are extremely gentle—offering the “floating” ultra-smooth experience reminiscent of classic Cadillacs of the Baby Boomer era—coupled with a user interface that emphasizes clarity over whimsy, along with numerous comfort features like push-button door closure and seat massagers.

      **The Basics**

      Positioned as a genuine six-figure flagship, the G90 certainly looks the part. Its design, which has remained largely unchanged since it first appeared a few years back, has proven to be quite timeless, primarily due to its understated elegance. It possesses the commanding presence desirable in a large luxury car without being overly ostentatious. The perfect term for this is: Classy.

      The standard-wheelbase G90 spans 207.7 inches, making it comparable in size to the 2026 S-Class (209.5 inches) but noticeably shorter than the 7 Series (212.2 inches). Genesis capitalizes on this space, offering exceptionally comfortable rear seats that evoke a first-class atmosphere often expected in such vehicles.

      All G90 models feature a 3.5-liter twin-turbo V6 engine, paired with all-wheel drive and an eight-speed automatic transmission. Upgrading from the base model adds a 48V E-Supercharger to the powertrain, increasing horsepower from 375 to 409, albeit with a slight drop in fuel efficiency (from 21 to 20 mpg combined).

      **What is an E-Supercharger?**

      Genesis has provided a detailed explanation of its innovative E-Supercharger system. The key takeaway regarding its advantages is:

      “Typically, a turbocharger relies on exhaust gases to spin the turbine after combustion, which powers a compressor wheel to push air into the engine, enhancing output. While boosting the turbocharger's capability can enhance airflow and overall output, it often results in delayed acceleration due to longer compression times. This can lead to slower throttle response when the engine is under load or running at low speeds.

      "The 48-volt e-supercharger addresses these issues by engaging at speeds below 1,750 RPM. It compresses air behind the compressor wheel and supplies it to the engine, enhancing low-end performance and minimizing turbo lag. As the engine reaches higher RPMs, where the turbochargers alone can provide sufficient boost, airflow bypasses the e-supercharger and goes straight to the engine intake manifold.”

      I appreciate that Genesis has thought to design a visually appealing engine cover.

      Essentially, while the system boosts peak horsepower, its most significant advantage is the substantial low-speed thrust, providing a powerful sensation.

      Models equipped with the E-Supercharger also include more upscale features, such as multi-chamber air suspension, rear-wheel steering, larger brakes, and additional amenities. The top-tier model we tested, the G90 3.5T E-SC MHEV Prestige Black AWD (yes, that’s the full name), boasts unique all-black accents, wheels, and light bezels, giving it a stoic, almost menacing look.

      **Driving the 2026 Genesis G90**

      Settling into the G90’s seats feels akin to collapsing onto your favorite couch after a long day at work. A wave of pleasure, relief, and security envelops you as you press a button, and the door effortlessly closes behind you. This feature takes some adjustment—I found myself often forgetting the doors were powered and sometimes struggled against the mechanism.

      The controls are straightforward and easy to locate, with the steering wheel designed for minimal resistance—boasting just two large spokes, allowing you to grip it comfortably in various ways.

      Accelerating feels almost as if the car is stationary while the world shifts around it. There’s a lack of sensation associated with speed, but it’s certainly not sluggish. This 5,000-pound car feels surprisingly light, almost as if it’s floating. While there is a sport mode—if you floor the gas pedal and steer with drama reminiscent of an ’80s action film—you’ll experience a significant amount of body roll, far more pronounced than its firmer German competitors. The G90 does not
