2021 Mercedes-Benz A-Class Review

Punchy engines, spry handling, and high-tech infotainment all help the Mercedes-Benz A-Class stand out among luxury small cars, but its scant passenger and cargo space are less praiseworthy. This vehicle does not have an overall score or ranking because it has not been fully crash tested.

Pros & Cons

  • Elegant cabin
  • Futuristic tech features
  • Sharp handling
  • Zippy acceleration
  • Somewhat harsh ride
  • Tiny trunk
  • Small rear seats

New for 2021

  • Blind spot monitoring, a 64-color ambient lighting system, and 18-inch wheels now standard

Thinking of leasing a Mercedes-Benz A-Class?

The U.S. News Best Price Program saves users an average of $3,206 off the MSRP, and a lower price equals lower monthly lease payments. That means you could see a savings of $90 a month on a 36-month lease.

Is the Mercedes-Benz A-Class a Good Car?

Yes, the Mercedes-Benz A-Class is a good luxury small car. This sedan impresses with its excellent fuel economy, ritzy cabin, and state-of-the-art infotainment system. It also has two peppy engine options and is fun to drive. However, the A-Class falters when it comes to trunk space and passenger room. Additionally, its ride can be too firm to be considered comfortable.

Should I Buy the Mercedes-Benz A-Class?

While there’s a lot to like about this Mercedes, there are better options if you want a more spacious interior or a more comfortable ride. The 2021 Audi A3 has about 15 cubic feet of trunk space, which is almost double what you’ll find in the A-Class. You could also consider the Mercedes-Benz C-Class, which comes in multiple body styles and has a refined ride.

2020 vs. 2021 Mercedes-Benz A-Class: What's the Difference?

For 2021, Mercedes-Benz adds blind spot monitoring to the A-Class’ standard features list. Also newly standard in the base model are 18-inch wheels and a 64-color ambient lighting system. Otherwise, this vehicle sees no major changes from the 2020 A-Class.

Compare the 2020 and 2021 A-Class »

Here are the key changes for the Mercedes-Benz A-Class over the last few years:

  • 2019: all-new vehicle

How Much Does the Mercedes-Benz A-Class Cost?

The base Mercedes-Benz A-Class A 220 has a starting MSRP of $33,650, which undercuts the starting prices of most cars in the class. The high-end AMG model starts at $45,850, which is more affordable than the performance-oriented models in the Audi A3 and BMW 2 Series lineups.

Mercedes-Benz A-Class Versus the Competition

Mercedes-Benz A-Class vs. Mercedes-Benz CLA

The Mercedes-Benz CLA is another luxury small car from the brand, and it is built on the same platform as the A-Class. Even so, there are some key differences between them. The CLA has a larger trunk, and the high-performance AMG CLA 45 trim has a lot more power. On the other hand, the A-Class has a bit more rear-seat headroom and a more affordable starting price.

Compare the A-Class and CLA »

Mercedes-Benz A-Class vs. Audi A3

The Audi A3 is another appealing luxury sedan. Its standard touch screen is larger than the one you’ll find in the base A-Class, and the A3’s trunk is nearly twice as big as that in the Mercedes. Otherwise, these two German rivals are similar, with spirited handling, potent turbocharged engines, and available high-performance trims.

A-Class Interior: A Small Glimpse of the Future

A-Class Cargo Space

With 8.6 cubic feet of space, the A-Class sedan’s trunk is one of the smallest in the class. A hands-free trunk lid is available.

How Many People Does the A-Class Seat?

The A-Class sedan seats five people. Synthetic leather upholstery and 12-way power-adjustable front seats come standard. Genuine leather upholstery is available, as are heated and ventilated front seats, sport front seats, multicontour front seats, and a heated steering wheel.

While it may be slightly roomier than the Mercedes-Benz CLA, the A-Class still comes up short on space. Fitting a tall passenger behind a tall driver would be a stretch due to a lack of rear-seat legroom. On the plus side, it’s easy to enter or exit the vehicle.

A-Class and Child Car Seats

There are two complete sets of LATCH connectors for the rear outboard seats.

A-Class Interior Quality

Premium materials adorn this Mercedes’ cabin, and a 64-color ambient lighting system is newly standard. Optional features like woodgrain trim help this luxury sedan feel even swankier.

A-Class Infotainment, Bluetooth, and Navigation

There are multiple ways to control the Mercedes-Benz User Experience (MBUX) infotainment system, and most of them are simple. The touch screen has tabletlike controls, with swiping and pinch-to-zoom functions, and it’s highly intuitive with crisp graphics and quick response times. There’s also a console-mounted touchpad controller, physical buttons on the steering wheel, and voice commands, including the “Hey, Mercedes” keyword activation.

  • Standard infotainment features: a 7-inch digital driver display, a 7-inch touch screen, a touchpad controller, five USB ports, Apple CarPlay, Android Auto, HD Radio, Bluetooth, and voice controls
  • Available infotainment features: a 10.25-inch digital gauge cluster, a 10.25-inch touch screen, gesture-based infotainment controls, a 12-speaker Burmester stereo, satellite radio, a Wi-Fi hot spot, navigation, and wireless device charging
  • Additional standard features: push-button start, remote start, dual-zone automatic climate control, and a panoramic roof
  • Other available features: proximity keyless entry

A-Class Performance: AMG? AM-Whee

A-Class Engine

This sedan comes with a choice of two turbocharged 2.0-liter four-cylinder engines. The engine in the base A 220 makes 188 horsepower and 221 pound-feet of torque. In the AMG A 35, the engine produces 302 horsepower and 295 pound-feet of torque. The sole transmission is a seven-speed dual-clutch automatic, which gets mixed reviews for its smoothness. Some critics report that it is clunky, while others say that it works fine.

The base engine’s numbers may be weak on paper, but it supplies ample power for regular driving and is surprisingly peppy. The AMG A 35 provides extra oomph and delivers power smoothly and confidently in just about any situation.

A-Class Gas Mileage

With its base four-cylinder engine and front-wheel drive, the A 220 gets an EPA-estimated 25 mpg in the city and 36 mpg on the highway. Adding all-wheel drive (AWD) lowers the highway rating to 34 mpg. Those are great estimates for the luxury small car class. The Mercedes-Benz AMG A 35 returns 22 mpg in the city and 29 mpg on the highway.

A-Class Ride and Handling

Confident brakes and well-weighted steering help make this sedan fun to drive. It doesn’t quite carve corners as eagerly as a sports sedan, but it gets pretty close. Unfortunately, the stiff suspension and run-flat tires can make the ride somewhat harsh. Front-wheel drive is standard, and AWD is available.

Mercedes-AMG A 35

Retailing for $45,850, the Mercedes AMG gains performance enhancements such as an AMG-tuned suspension, high-performance brakes, a sport exhaust, dynamic cornering assist, a Sport+ drive mode, and all-wheel drive. The AMG A 35 also comes with the 10.25-inch touch screen and a 10.25-inch digital driver display.

Many of the same packages are available. There’s also a $3,270 AMG Performance Seat package, which outfits this vehicle with heated, multicontour front sport seats. For $1,100, you can add a head-up display, and for $990, you can get a sport-tuned suspension with three-stage damping to adjust the ride quality.

The Final Call

The Mercedes-Benz A-Class is a high-end luxury small car that impresses with its lively engine choices, playful handling, sumptuous cabin, and high-tech infotainment system. However, it also has a paltry trunk and tight back seats, as well as a harsh ride in models with the standard tires.

Don't just take our word for it. Check out comments from some of the reviews that drive our rankings and analysis.

  • "Rather than skimp on things like the quality of materials in the cabin, Mercedes-Benz has made the A-Class a well-realized premium car stocked with many fine features, while making others available in the options list." -- Autotrader
  • "At relatively accessible pricing, the 2021 Mercedes-Benz A-Class may well be the gateway to luxury-car ownership and the beginning of a beautiful brand loyalty for younger buyers. Yet it could just as easily be a smart choice for any members of the Mercedes-Benz faithful looking to downsize (or purchase a second or third vehicle) without sacrificing quality, driving manners, and cool technology." -- Kelley Blue Book
  • "The A-Class excels at offering the modern Mercedes-Benz experience in simply a smaller package. It's loaded with tech, features and luxury. It's also enjoyable to drive and looks suitably upscale. Mercedes has raised the bar for the entry-level luxury sedan class." -- Edmunds (2020)
