2021 Kia K5 Reviews SummarySedans are now the most exciting new cars in the mainstream market. They are to crossovers today what craft beer was in the early 2000s. They’re not on every corner anymore because Americans prefer trucks over cars, but sedans like the 2021 Kia K5 are refreshing to see, surprisingly good to drive, and will make you look cultured and smart without having to try. The K5—and its new name—replaces the Optima and upgrades nearly everything in the pursuit of style and performance. It’s one of the best midsize sedans out there. | |
2021 Mercedes-Benz S-Class Reviews SummaryThe 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. | |
