2021 Mercedes-Benz S-Class Reviews Summary

The S-Class not only sits at the top of the Mercedes hierarchy in price and prestige, but it has also long served as a technological showcase. In the press release for the redesigned 2021 S-Class, Mercedes repeatedly noted the innovations—from anti-lock brakes to airbags—that were introduced on the big sedan and eventually trickled down to mainstream vehicles.

With the previous generation dating back to the 2014 model year (with a significant update for 2018), the Mercedes-Benz S-Class was in need of an update to maintain that status, and to keep pace with other full-size luxury sedans like the Audi A8, BMW 7 Series, and Lexus LS. To do that, the new S-Class gets a more sophisticated infotainment system, new powertrains, and more aerodynamic bodywork, among other features.

The 2021 S-Class launches in two configurations, both with 4Matic all-wheel drive (AWD) and EQ Boost mild-hybrid systems. The S500 4Matic has a six-cylinder engine, while the S580 4Matic has a V8. We spent a few days with the Mercedes-Benz S580 for this review. A Mercedes-Maybach S680 4Matic version will follow in the first half of 2022, and you can expect a new AMG performance version sometime in the future as well.

2022 Kia K5 Reviews Summary

Last model year, as part of a redesign of its midsize sedan, Kia changed the car’s name from Optima to K5. Rakishly attractive and an undeniably good value, the new Kia K5 is an appealing choice in a shrinking vehicle segment where it faces fewer rivals with each year that passes. For the 2022 model year, the K5 wears Kia’s redesigned emblems, upper trim levels add standard features, and a new Premium option package for the GT-Line AWD installs upgraded headlights, a heated steering wheel, a panoramic sunroof, Highway Driving Assist technology, and adaptive cruise control that can automatically adjust vehicle speed for curves.
