2025 Genesis G90 vs. Lexus LS – Ultimate Luxury Showdown

The full-size luxury sedan segment has two fierce rivals in the 2025 Genesis G90 and Lexus LS. They’re both luxury heavy-hitters, but they take different paths to pamper you on your daily drive. The G90 delivers value-packed luxury with competitive pricing and next-level features, while the LS relies on its long-standing luxury pedigree. At Genesis of Columbia in South Carolina, we’ve taken a deep dive into their features, performance, and value to help you figure out which one might be the perfect fit for your garage.

Comparing the 2025 Genesis G90 vs. Lexus LS

Genesis, Hyundai’s luxury division, hit the high-end market in 2015. Its flagship G90 challenges luxury norms with bold styling and competitive pricing. Lexus, Toyota’s luxury arm, has dominated premium cars since 1989, with the LS serving as its premier sedan.

For 2025, the G90 comes in just two all-wheel-drive trims: the 3.5T and the 3.5T e-Supercharger, so your choice boils down to whether you want the standard twinturbo V-6 or the more powerful electrically boosted version. The LS lineup includes the LS 500, LS 500 F SPORT, and LS 500h hybrid, each with rear- or all-wheel drive.

The 2025 Genesis G90 starts at $89,700, while the Lexus LS begins at $81,685. Don’t be fooled by this difference. The G90 delivers exceptional value with its standard features and a five-year/60,000-mile basic warranty, 10-year/100,000-mile powertrain warranty, and free maintenance for three years/36,000 miles.

Design and Aesthetics

The 2025 Genesis G90 sits on a 125.2-inch wheelbase, stretches to 207.7 inches long, and rocks a shield-shaped grille paired with split LED headlights that give it a modern vibe. Inside, the driver-focused cockpit uses real wood and metal with tangible quality differences, while a built-in Mood Curator system harmonizes ambient lighting, seat massage, subtle fragrance diffusion, and the immersive Bang & Olufsen audio to match whatever mood you’re in.

The Lexus LS takes a more subtle route, with clean lines and refined styling cues that embody classic luxury. It’s slightly smaller, with a 123-inch wheelbase and 206.1-inch overall length. Inside is where the LS really shines. The standard 12.3-inch touch screen looks futuristic, while hand-pleated door panels and cut-glass decorative elements showcase craftsmanship few rivals attempt. With the Executive package, you can turn your LS into a fancy four-seater with quilted leather and rear seats that recline and massage.

Performance and Specifications

The 2025 G90 offers two potent engines. Its standard 3.5-liter twin-turbo V-6 produces 375 horsepower and 391 lb-ft of torque, paired to an eight-speed automatic and all-wheel drive. For more power, the e-Supercharger adds electric boost to the twin-turbo V-6, delivering 409 horsepower and a 0-to-60 mph sprint time of 5.1 seconds, which is impressive for such a large luxury sedan.

Lexus counters with a twin-turbo 3.4-liter V-6 producing 416 horsepower and 442 lb-ft of torque through a 10-speed automatic. The LS500 goes from 0 to 60 mph in just 4.6 seconds and runs quarter-miles in 13.3 seconds at 107 mph. Neither are sports cars, but both deliver surprising speed when needed.

Fuel Economy

Both these luxury sedans do surprisingly well at the pump, considering their size and power. The G90 e-Supercharger gets EPA ratings of 17 mpg in the city, 24 mpg on the highway, and 20 mpg combined.

The Lexus LS500 F Sport AWD managed 28 mpg during 75-mph highway testing, beating its EPA number by 1 mpg. If you’re a regular road-tripper, that could mean fewer pit stops and more time enjoying the journey.

Technology

The 2025 G90 comes loaded with tech. Standard Wi-Fi and welcome lighting greet you on approach, while its quick infotainment system works smoothly with Apple CarPlay and Android Auto. The 23-speaker Bang & Olufsen system delivers sound so real you’d think the musicians were right there with you and offers various venue acoustic settings.

Lexus matches with its stunning 12.3-inch touch screen and windshield head-up display for easy info access. If you’re a music fan, you’ll love the optional 23-speaker Mark Levinson system packing 2,400 watts.

Safety Features

The G90 comes packed with driver aids. Standard features include forward collision-avoidance assist, smart cruise control with stop and go, blind-spot collision-avoidance assist, safe exit assist, and highway driving assist.

Every 2025 Lexus LS is delivered with Lexus Safety System+, bundling a precollision system with pedestrian detection, dynamic radar cruise control, lane tracing assist, lane departure alert with steering assist, road sign assist, and automatic high beams.
