2020 Nissan Sentra Reviews Summary

For 38 years, Nissan has peddled the Sentra as its definitive starter car. It’s a household name like Civic, Corolla, and Jetta—all of which are brand-new or have been refreshed in the last couple of years. The eighth-generation Sentra has the look of a larger, more luxurious car. It reflects major upgrades in style, technology, and driving dynamics. Compact sedans have a high bar to clear, even at $20,000. The 2020 Sentra delivers in every respect.

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.

2021 Mercedes-Benz S-Class
7/10

The 2020 Nissan Sentra marked a significant departure from its traditionally plain design, offering a more appealing aesthetic. The model resembled a scaled-down Altima, giving it a larger presence than its actual size. The Sentra's design was characterized by a lower and wider stance, with elegant creases in the sheet metal that added a touch of sophistication. The V-shaped grille motif was mature and recognizable, and the interior featured upscale elements like a flat-bottom leather steering wheel and leatherette dash, elevating its class. Despite some hard plastic components, the Sentra's fit and finish were commendable, rivaling even the Mazda3 in terms of interior quality.

In contrast, the 2021 Mercedes-Benz S-Class maintained a familiar exterior design but boasted a drag coefficient of 0.22, making it aerodynamically superior. The S-Class was slightly larger than its predecessor, with a longer wheelbase and increased dimensions. Its interior was designed around a prominent infotainment touchscreen and digital instrument cluster, with a minimalist approach that eliminated clutter. The ambient lighting system was a standout feature, offering 64 colors and integrating with infotainment and driver-assist functions. The interior materials were luxurious, with Nappa leather upholstery and open-pore wood trim, although the piano-black trim was prone to smudging.

Performance

9/10

The 2020 Nissan Sentra was powered by a 2.0-liter inline 4-cylinder engine, producing 149 horsepower and 146 pound-feet of torque, paired with a continuously variable transmission (CVT). While it lacked turbocharged engines and manual transmissions, the Sentra offered smooth and responsive performance. The independent suspension improved handling, providing a flat cornering experience and agreeable ride quality. The steering was quick and precise, contributing to a sense of control. Fuel economy was impressive, with an EPA rating of 29 mpg city, 39 highway, and 33 combined.

The 2021 Mercedes-Benz S-Class offered two engine options: the S500 4Matic with a 3.0-liter turbocharged inline-six engine producing 429 horsepower and the S580 4Matic with a 4.0-liter twin-turbo V8 generating 496 horsepower. Both models featured EQ Boost, a mild-hybrid system that added electric assist. The S-Class delivered quick acceleration, with 0 to 60 mph times of 4.8 seconds for the S500 and 4.4 seconds for the S580. The standard air suspension and rear-wheel steering enhanced ride comfort and maneuverability. While not a driver's car, the S-Class maintained composure on twisty roads, with precise steering and minimal body roll.

The 2020 Nissan Sentra offered a surprisingly spacious backseat, accommodating taller passengers comfortably. The front seats featured Nissan's Zero Gravity cushioning, reducing fatigue on long drives. The lowered body profile improved side visibility, although the rear window's design limited the view. The trunk provided 14.3 cubic feet of space, which was generous for a compact sedan, and the seatbacks folded for additional cargo capacity.

The 2021 Mercedes-Benz S-Class provided more headroom and rear legroom than its predecessor, with segment-leading shoulder room. Cargo space increased to 12.9 cubic feet, although it remained smaller than some competitors. The front seats were highly adjustable, with heating, ventilation, and massage functions. The removal of analog controls freed up storage space, and rear-seat passengers enjoyed a large console with cupholders and climate controls. The optional Executive Line package added features like power-adjustable rear seats and four-zone climate control.

The 2020 Nissan Sentra lacked some advanced features like ProPilot, navigation, and wireless charging, but it offered standard Apple CarPlay, Android Auto, Amazon Alexa, and WiFi on the mid-level SV trim. The SV also included dual-zone climate control, adaptive cruise control, and a full suite of driver-assist features. While basic, the Sentra's technology package was adequate for its price point.

The 2021 Mercedes-Benz S-Class featured a 12.3-inch digital instrument cluster and a 12.8-inch OLED central touchscreen, with wireless Apple CarPlay and Android Auto. The updated MBUX infotainment system offered increased computing power and relied more on the touchscreen. The S-Class included an augmented-reality head-up display and a 30-speaker Burmester audio system. While some tech features were gimmicky, the voice-control system and personal profiles added convenience.

Safety

The 2020 Nissan Sentra had not been crash-tested by NHTSA or IIHS, but it was expected to receive top ratings. It included rear side airbags, knee airbags, and a comprehensive suite of driver-assist features, such as forward and reverse emergency braking, pedestrian detection, and blind-spot monitoring.

The 2021 Mercedes-Benz S-Class also lacked crash-test ratings but offered a wide array of safety features, including an industry-first rear-passenger airbag. Standard driver-assist features included adaptive cruise control, automated lane centering, and a 360-degree camera system. Mercedes claimed improvements in these systems, with enhanced traffic-sign recognition and lane-keep assist.
