2017 Genesis G90 Performance Review

Note: This performance review was created when the 2017 Genesis G90 was new.


Performance: 9.0

Performance is a high point for the 2017 Genesis G90. Its base V6 engine is amply powerful, with the V8 offering just a little more muscle. Ride quality is excellent, and the adaptive suspension smooths over bumps nicely. Handling is agile for a car of this size, and the G90 grips the road surprisingly well.

  • "G90 has this creamy luxuriousness to it like an experienced pour of Irish stout." -- Motor Trend
  • "The engine is really the best part of the G90 we tested. There's no rubber-banding as the turbos spool up. To put it another way, it's a turbo V6 doing a great interpretation of a well-tuned, large displacement V8. Though it is subdued at mild throttle inputs, the Lambda pipes up with a gruff note when you wale on it – that's at least partly due to a simulated engine noise like many of its competitors use. And there's an absolutely monumental amount of sound deadening under the hood, so I doubt you'd hear a peep from the Lambda if it wasn't piped through the speakers." -- Autoblog
  • "Put the G90 in motion and there's no doubt you're at the helm of a generously proportioned car of considerable bearing - almost 2-1/2 tons worth. Yet the Genesis flagship doesn't feel cumbersome." -- New York Daily News

Acceleration and Power

If you get the base model, it comes with a 3.3-liter twin-turbocharged V6 engine that produces 365 horsepower. Both rear- and all-wheel-drive models with this engine return 17 mpg in the city and 24 mpg on the highway. That's below average for the luxury large car class.

A 5.0-liter V8 engine is also available, and it makes 420 horsepower. With rear-wheel drive, expect 16 mpg in the city and 24 on the highway. All-wheel-drive V8 models get 15/23 mpg city/highway.

Acceleration with the base engine is strong, and the V6 doesn't lag like other turbocharged engines. A standard eight-speed automatic transmission shifts smoothly when cruising, yet it's responsive the moment you need more power for passing. The available V8 offers more power, but it's not enough to justify the extra cost.

  • "The G90 V6 feels light in spite of its 4,600-pound curb weight, and not big at all, and it's quick when you want it to be. We're not talking about acceleration toward infinity as one can experience in a 12-cylinder Bentley, but strong, invigorating bursts when it's time [to] make up ground or get clear of a pack. There's almost no indication the engine is turbocharged -- not from noise or legitimate lag or throttle response -- and the torque band is as wide as they come. There's nothing obvious to complain about in the transmission, either. Upshifts are positive under hard throttle and almost imperceptible at a casual pace. Downshifts come quickly, and the G90 is happy to drop two, three gears at a time." -- Autoweek
  • "I drove both rear- and all-wheel-drive versions of the G90 V-6. This is the first twin-turbo V-6 to come out of the Hyundai family and its execution is great. Peak torque comes on at only 1,300 rpm and it feels more like a naturally aspirated engine than any other turbo I've gotten behind the wheel of, with no real turbo lag and smooth power delivery rather than the 'kick' you get with some turbos. It also offered plenty of responsiveness for passing and quick merges, and it has what I'd call the 'easy' power that a big luxury sedan needs – the engine doesn't really feel taxed when you accelerate." -- Cars.com
  • "Yes, you can also get a Genesis G90 with a V-8 engine, which is a carryover from the Equus. Packing 420 hp and 383 lb-ft of torque, a rear-wheel-drive G90 V-8 tester hit 60 mph 0.4 second quicker than the V-6 model. Don't expect to notice the difference on the road, however. The V-6 proves more than competent enough in daily driving, and our editors agreed after driving both that there's no compelling reason to move up to the V-8, because they feel similar dynamically." -- Motor Trend

Handling and Braking

With its standard adaptive suspension, you can customize the G90's ride to suit your driving style whenever the mood strikes. Overall, the ride is supple but not so much that you feel disconnected from the road. The G90's smooth ride makes it comfortable for long trips. 

The adaptive suspension does a great job smoothing out roadway imperfections and also helps improve body control around turns. Switch into Sport mode, and you'll feel positively glued to the road when cornering. Steering has a heavier feel, and it offers good feedback. The brakes are quick when you need them to be, with a firm and reassuring feel.

  • "Brake feel is satisfyingly firm and responsive, body motions are kept nicely in check, and the electrically assisted steering is relatively hefty, with secure on-center tracking and a modicum of feedback." -- Car and Driver
  • "When you're cruising in traffic it's smooth and quiet, and at speed, the ride borders right on the edge of being too soft, but is still perfectly acceptable. The G90 is the kind of car you could drive for hours on end and arrive feeling relaxed and refreshed. Yet put the G90 into Sport mode and the car's suspension stiffens, giving it just enough bite that you'll think, 'Hey, what if I cook it through that onramp?' When you do, you'll be pleasantly surprised as this big sedan takes a bite and holds on, with steering that's remarkably communicative, and eye-opening grip. Put another way, from the driver's seat the 2017 G90 is at least the equal of the Lexus LS 460." -- Kelley Blue Book
  • "Driving is a hushed, controlled, and relaxed experience. Hyundai claims best-in-class levels of quiet and low vibration. To get there, Hyundai went so far as to specially design the standard 19-inch aluminum wheels with integral sound-absorbing chambers for reduced tire noise. An adaptive suspension with electronic damping filters out most road imperfections while simultaneously minimizing roll." -- Automobile Magazine
