The G90 is Genesis's large-sedan flagship, and it's packed to the gunwales with features that typically belong to the ultra-luxury sphere. The elegant cabin masterfully shuffles a deck of leather, wood, metal, and microsuede trim, and there are reclining rear seats that heat, cool, and massage. Isolation and comfort dominate the experience. Material choices look and feel expensive, and all controls move with a satisfying slickness. Whether you're wafting along at 45 mph or 90 mph, the interior remains serene even as the scenery blurs outside.
A few taps of the 12.3-inch touchscreen have the 1700-watt, 23-speaker Bang & Olufsen audio system singing in different soundscapes. If you've always wondered how Dua Lipa or Jimmy Buffett might sound in Boston's Symphony Hall, the G90 is equipped to answer those burning questions. (They sound great.) Pause the music and start talking and you'll notice that microphones placed in the headliner pick up your voice and make it sound like you're standing in a concert hall yourself. The G90 is certainly big inside, at 105 cubic feet, but it's not theater big.
Despite a slippery drag coefficient of 0.27, the supercharged G90's 19.3-gallon tank empties at a rate of 24 miles per gallon on the highway and 17 mpg in the city, according to EPA estimates. The base engine manages 18 and 26 mpg, respectively. These numbers fall short of the six-cylinder-equipped Audi A8L and Mercedes-Benz S500 and are more in line with V-8 versions of the Audi and Benz. The supercharged G90's 20-mpg EPA combined rating does represent a 2-mpg improvement over the 2022 V-8 AWD model, however.
The G90 has never sold in high volumes, yet Genesis still put a lot of effort into the latest version of its big sedan. Whether you're driving or riding in that huge back seat, the G90 is comfortably numb when you want that and refined in a way that reaches well beyond its near-six-figure price. Brand snobs might not be impressed by the Genesis badge, but if we were valets, we'd leave this one out front.
