How Does The Genesis G80 and G90 Compare Under the Hood?
The Genesis G80 gives you two engine options, which is a nice advantage if you want some flexibility. The base setup is a 2.5L turbocharged four-cylinder that produces 300 horsepower and 311 lb.-ft. of torque. It runs through an 8-speed automatic transmission with all-wheel drive and returns an estimated 20 mpg in the city and 29 on the highway. For a luxury sedan you plan to drive every day, those numbers are solid.
If you want more punch for the G80, the available 3.5L twin-turbo V6 bumps output up to 375 horsepower and 391 lb.-ft. of torque. This version also adds electronically controlled suspension with road preview and sport tuning, which gives the G80 a noticeably sharper driving feel when you want it.
The Genesis G90 starts where the G80 leaves off. Its standard engine is already the 3.5L V6 with 375 horsepower and 391 lb.-ft. of torque. From there, you can step up to a 3.5L twin-turbo V6 with a 48V e-supercharger that pushes output to 409 horsepower. That is a considerable jump, and it makes the G90 feel more effortless at highway speeds or during longer drives around Marietta, GA.
Both sedans come with advanced suspension systems designed to absorb rough pavement and keep the ride smooth, so either one handles a daily commute with ease.
Which Model Has Better Technology?
Both cars are well-equipped, but they take different approaches to how that technology is presented inside the cabin.
The Genesis G80 leans into its display setup. The 27-inch OLED screen stretches across the dashboard and combines the instrument cluster and navigation into one wide, uninterrupted panel. It looks modern and feels easy to read at a glance. Wireless Apple CarPlay and Android Auto, a 9-speaker premium audio system, Genesis Connected Services, fingerprint authentication, and a built-in Wi-Fi hotspot round out the tech package nicely.
The Genesis G90 goes in a slightly different direction. Instead of one large display, it uses two separate 12.3-inch screens for the instrument cluster and navigation. The audio system steps up to Bang and Olufsen, which is a serious upgrade in sound quality. You also get wireless phone charging, Genesis Digital Key 2, Active Noise Control, and Remote Smart Parking Assist 2. That last feature is especially useful in busier parking situations around Woodstock, GA.
Neither approach is wrong. The G80 gives you a more visually unified cockpit, while the G90 focuses on premium sound and added convenience features.
What Is It Like Inside The G80 and G90?
The Genesis G80 interior is comfortable and well-designed. You get leatherette seating surfaces, heated front and rear seats, a heated steering wheel, and adjustable ambient lighting. Power front seats with lumbar support make it easy to dial in a comfortable driving position, and the overall layout is clean without feeling plain. It is a pleasant place to spend time, whether you are driving across town or covering longer stretches of road.
The Genesis G90 takes the interior in a more premium direction. Nappa leather replaces leatherette, and details like a microfiber suede headliner and matte finish wood trim give the cabin a more upscale, deliberate feel. The front seats add a massage function and ventilation on top of heating, and rear passengers get heated seats as well. A head-up display, multi-zone climate control, rear sunshades, and the Mood Curator system all contribute to an experience that feels more like a personal retreat than a car interior.
Which Genesis Sedan Is Right for You?
The G80 is a great choice if you want a well-rounded luxury sedan that performs well, looks good, and does not ask you to overthink the decision. The G90 is worth the step up if a more refined interior and a few extra layers of comfort and technology are important to you.
The best way to figure out which one feels right is to experience both in person. Visit Genesis of Kennesaw to explore the G80 and G90 models side by side and find the one that fits your daily life.
