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. | |
2021 Honda Accord Reviews SummaryFor the 2021 model year, Honda is taking the Accord in a more elevated direction. The company has refined the Accord’s features list, added a trim level, and priced it right to compete against other heavyweights in the industry. Honda has made safety a priority in the 2021 Accord, helping this fresh version earn high praise. | |
