2021 Audi A4 Sedan Review: Smooth Operator

by Aiden Eksteen

There are very few cars that exude sophistication, professionalism, and class quite like an Audi sedan, and the 2021 Audi A4 Sedan is perhaps the most authentic example of those qualities. Audi offers high-performance versions of many of its nameplates, typically monikered under the S and RS badges, but the A4 Sedan, as one of the German automaker's base-line variants, focuses on the comfort and convenience side of things. That doesn't mean it isn't still a very pleasant and proficient cruiser; however, with its lively 2.0-liter inline-4 engine dialed to yield up to 201 horsepower in 40 TFSI variants and up to 261 hp in the 45 TFSI variants. Vivacious yet smooth acceleration is met with confidence-inspiring and adept handling characteristics and a serene ride quality to boot, all by virtue of Audi's masterful chassis engineering and inclusive quattro all-wheel drive setup. In a class comprising other compact luxury sedans like the acclaimed BMW 3 Series and the illustrious Mercedes-Benz C-Class, is the fifth-generation Audi A4's demure and balanced persona enough to call it a class-leader?

2021 Audi A4 Sedan Changes: 🚙What’s the difference vs 2020 Audi A4 Sedan?

The 2021 Audi A4 receives very light revisions under the skin, as last year's model got some fresh new looks. A review of the changes for the new model year shows that the sedan now comes with 13 horsepower more under the hood on both versions of its four-pot, thanks, in part, to a new 12-volt mild-hybrid system. Other updates include standard wireless Apple CarPlay and lane departure warning systems. The mid-level trim gains adaptive cruise control and some additional safety equipment while the top Prestige trim now gets standard heated rear seats. The A4 45 TFSI can now be equipped with a Black Optic package with either 18-inch wheels/all-season tires or 19-inch wheels/summer tires.

Pros and Cons

  • Compliant and serene ride
  • Slick and refined transmission
  • Relatively good gas mileage
  • Comprehensive infotainment system
  • Oodles of inclusive features
  • Doesn't have all that much character
  • Some optional features should be standard
  • Trunk space is just average

Verdict: 🏁Is the 2021 Audi A4 Sedan a good car?

With just a general review of the 2021 Audi A4 Sedan, you'll be able to tell that it's a solid and well-rounded, premium 4-door sedan. It's not the most exciting vehicle, especially from Audi, and it isn't likely to turn heads either or offer anything to really brag about. That isn't what the A4 Sedan is about, however. It's a consummate businessperson's runabout with a modest but distinctly classy aesthetic and it aims to provide just what one would need to drive about hassle-free and comfortably. Its powertrain delivers polished and balanced performance in either modulation and manages to remain decently fuel-efficient, too. It has a modern and high-class cabin brimming with good features, though there are some options that we feel should have been standard, including the blind-spot monitor. With its top-notch safety rating and exceptional reliability standards, it's ideal for the school run and weekend getaways, too. There are a lot of compact sedans in the USA but very few can match the premium look and feel , not the price of the 2021 Audi A4 Sedan.
