G90 vs. S-Class: power and comfort

Genesis G90

A full-size luxury sedan with loads of standard features and either a twin-turbo V6 or an optional V8 engine, the 2021 Genesis G90 is a very attractive option in its segment that is priced significantly lower than many of its competitors. While there is a Sport setting that quickens throttle response and tightens up the suspension, the goal of the G90 is to provide its driver and passengers with a calm and comfortable ride on long journeys. Rear-wheel drive is standard, although all G90s can also be optioned with all-wheel drive.

Handsome and sophisticated, the G90 is well made and full of Nappa leather, smooth wood, and stainless steel speaker grilles. If there’s one complaint, the interior still has a bit of an old-school analog approach to its luxury interior.

A strong point is that even the base model G90 is extremely well equipped. It includes features such as heated/ventilated power-adjustable front seats, heated rear seats, satellite radio, a 17-speaker/900-watt Lexicon surround-sound system, and a 12.3-inch infotainment system.

Also standard is a suite of safety and driver-assist features that includes lane-keeping assistance, adaptive cruise control, forward-collision mitigation, a 360-degree camera system, and blind-spot monitoring. Resale values are average. The 2021 G90 includes a 10-year/100,000-mile powertrain warranty to go along with free scheduled maintenance and concierge services.

Mercedes-Benz S-Class

A powerhouse among luxury sedans, the 2021 Mercedes-Benz S-Class continues to hone its reputation as the benchmark by which all others are judged. A choice of powerful engines combines with all-wheel drive to make this large sedan both powerful and stable.

Performance is strong yet steady, with rear-axle steering helping the big sedan perform like a smaller car. There are also a couple of sporting variants of the S-Class from Mercedes’ AMG performance division, but those are in a completely different world in terms of not only performance but pricing.

Build quality and interior comfort are exceptional, with plenty of head- and legroom for five passengers and fine craftsmanship. Standard features include leather upholstery, heated and cooled massaging seats, a panoramic sunroof, and an exceptional Burmester 15-speaker audio system.

A massive center touchscreen controls such things as temperature, navigation, and infotainment, and while there are fewer buttons than we’d like, the Mercedes user interface system makes it easy to use voice commands for things such as temperature change and navigation. Other standard features on this six-figure luxury sedan include wireless Apple

CarPlay/Android Auto, a 360-degree camera, six USB ports, and 19-inch wheels.

Other trims include the AMG line, with different optional wheels and a special body package, and the Executive line, with Nappa leather upholstery, electrically adjustable rear seats, and rear-seat touchscreens. Safety features include rear passenger airbags, Pre-Safe Plus that tightens the seatbelts and closes the sunroof if it senses a collision, and a system that raises the car if it detects a side-impact crash.
