What we like: Handsome looks; standard all-wheel drive; choice of engines, with mild-hybrid assist; excellent materials and quality

What we would change: Add a hybrid or electric powertrain; price is high, particularly for the S trims

Overview: If the three German makes were the three bears, the 2021 Audi A6 would be the soup that’s just right, providing a perfect balance between the sportiness of BMW and the comfort levels of Mercedes-Benz. A superlative 7-speed automatic, combined with the excellent grip provided by Audi’s quattro all-wheel-drive system and a well-tuned suspension make the A6 an excellent handler. But it’s also plush and the suspension comfortable enough for long-distance touring, with plenty of space for passengers and acres of leather upholstery and walnut inlays. Also included are heated 8-way power-adjustable front seats, ambient interior lighting, and an infotainment system including navigation as well as Apple CarPlay/Android Auto integration.

Safety features include Pre Sense Front, which can automatically apply the brakes in an emergency, as well as lane-departure warning and front and rear parking sensors. Options are numerous, including an upgrade stereo system and a sport suspension. At the very top is the S6, with power coming from a twin-turbo V6. These models are almost in a different category, not dissimilar from a BMW M or an AMG Mercedes, with much more aggressive suspension tuning, steering, and brakes. However, the S6 is priced accordingly, starting at $80,000. Due to their excellent build quality, Audis hold their value well.

What’s new for 2021: Given that the A6 was redesigned just a couple years ago, changes for 2021 are relatively mild, including keyless entry now becoming standard and both a surround-view camera and 10.1-inch display being added to the base model options list. Adaptive Cruise Assist now comes standard on the Premium Plus trim, and a power rear window shade comes standard on the Prestige trim.

Features and technology: The 2021 Audi A6 comes with a choice of three engines, although the top twin-turbo V6 model is actually called the S6. Trim levels start with the basic Premium and include the Premium Plus and Prestige, although the Premium model is still quite well equipped, with leather upholstery, tri-zone climate control, heated 8-way power-adjustable front seats, keyless entry, and a power-adjustable steering wheel with shift paddles. The standard infotainment system includes twin-panel displays, Apple CarPlay/Android Auto integration, and a navigation system. Standard safety features include Audi’s Pre Sense Front, which can automatically apply the brakes in an emergency; lane-departure warning; and front and rear parking sensors. The Premium Plus adds a Bang & Olufsen premium sound system, adaptive cruise assist, Audi Side Assist, and Pre Sense rear, and a top-view camera with a virtual 360-degree view.

The top A6 is the Prestige, with heated and ventilated 12-way power front seats, adaptive cruise control, all-wheel steering, and four-zone automatic control. Models equipped with the 2.0-liter turbo are designated 45, while those with the 3.0-liter turbo are designated the 55, and also add the S line exterior appearance package.

The S6 Premium Plus model, aside from its 444-hp twin-turbo V6 engine, includes the S exterior design with 20-inch wheels and an adaptive air suspension, and the top dog S6 Prestige adds a cabin air ionizer, power soft-close doors, a head-up display, and adaptive cruise control with traffic jam assist.

What does the future hold: Given that the A6 was redesigned only two years ago, we don’t expect too many changes in the near future, although since Audi uses mild-hybrid technology and already makes an electric sedan (the e-tron), we would like to see either a hybrid or full-electric A6 (E6?) in the near future.

2021 Genesis G80

 

2021 Genesis G80

Base price: $47,700 / Read our 2021 Genesis G80 Review

What we like: Unique looks; optional all-wheel drive; plenty of driver assists; powerful optional V6; optional adaptive suspension; great warranty.

What we would change: Add a V8 option and a hybrid; increase the trunk size; console dial is challenging to use while driving.

Overview: Completely redesigned with a bold new look and a choice of engines ranging from a turbocharged four-cylinder to a twin-turbo V6, the 2021 Genesis G80 is a distinctive-looking midsize sedan that provides luxury, comfort, and a load of standard features at a reasonable price. Rear-wheel drive comes standard, but all-wheel drive is also available, as well as a camera-based adaptive suspension, and various drive modes change the response of the steering and throttle. Visibility is solid and the front seats are comfortable and supportive. Despite the sloped roofline, rear seat comfort is also good, although if we do have one complaint, the trunk is a little small. The interior is clean and uncluttered, although a 14.5-inch infotainment screen takes up a big part of the dash. It’s operated by a console-mounted dial that also incorporates handwriting recognition, although that isn’t terribly practical while one is driving. The G80 also comes loaded with standard features, including plenty of driver-assist and safety functions, 12-way power heated front seats, keyless entry, and both navigation and Apple CarPlay and Android Auto integration. For an extra bit of confidence, Genesis includes a class-leading 10-year/100,000-mile powertrain warranty.

What’s new for 2021: A complete redesign means everything is new for 2021, with a new shape and a new interior. A new camera-based adaptive suspension reads the road and adjusts the ride for more comfort and precise handling. Most significantly, the base V6 has been replaced with a turbocharged four-cylinder, and the top V8 engine has been dropped.

Features and technology: As with the Lexus, the Genesis G80 comes well equipped right off the bat, although there are only five trims compared with the eight of the Lexus. Standard features include 12-way power and heated front seats, keyless ignition, adaptive cruise control, 18-inch wheels, a leather-wrapped steering wheel, blind-spot monitoring, rear cross-traffic collision avoidance, and forward automatic emergency braking with pedestrian protection. A 14.5-inch infotainment screen includes Apple CarPlay/Android Auto, Bluetooth, and a navigation system.

Options include a camera-based adaptive suspension, surround-view monitor, both 19- and 20-inch wheels, ventilated front seats, heated rear seats, Nappa leather upholstery, wireless device charging, remote smart-parking assist, and a panoramic sunroof, among other things.

What does the future hold: We expect Genesis to follow the lead of Lexus by staying the course and building its brand cachet against the Germans. Given that the 2021 redesign was significant, we don’t expect more than incremental changes in the years ahead, although we would like it if there was a G80 hybrid. Find a 2021 Genesis G80 for sale
