2023 Mercedes-AMG GLA-Class Review, Pricing, and Specs


Properly turning a standard Benz into an AMG requires more than just a boosted engine and a waterfall grille. Take the 2023 Mercedes-AMG GLA-Class, for example, which does get both of those things, but also offers improved handling via a retuned suspension and sticky tires. The AMG version of the GLA-Class is a fiery little crossover that brings two levels of heat, with either 302 or 382 horsepower under its stubby hood. There are also compromises. For example, the ride is flinty and may be a bit too stiff for daily use. But if you’re concerned about comfort above all else, you’re probably not considering an AMG anyway—that’s what the standard Benz GLA is for. The Mercedes-AMG brand is one dedicated to performance, and its products are carefully engineered to deliver just that.

What’s new for 2023?

The AMG GLA-Class duo rolls into 2023 with no changes. They both pack ever-hot turbocharged four-cylinder engines and still offer more practicality than their sedan sibling, the CLA-Class.

Prices and which one to buy

Both the GLA35 and GLA45 have a host of standard performance features, including all-wheel drive and a tuned-and-tuned suspension that pumps up the driving excitement far over the regular Mercedes-Benz GLA250. From an enthusiast’s perspective, that 382-hp turbo four fitted to the GLA45 makes it the most compelling choice, and it’s the one we’d pick.

Engine, transmission and performance

The base, AMG-massaged turbocharged four-cylinder makes 302 hp in the GLA35, and Mercedes claims it’s enough to zip the SUV to 60 mph in just 5.0 seconds. The higher-powered GLA45 can do the same deed in a claimed 4.3 seconds. In our testing, the previous-generation GLA45—which made 375 hp—hit 60 mph in 4.0 seconds, so we think Mercedes is being conservative with its acceleration claims for both of these improved models. AMG engineers imbued these versions with the same amount of athleticism as the previous generation AMG GLA-Class, but could work in a touch more ride comfort. The previous generation model offered very little suspension compliance, resulting in a harsh ride.

Fuel Economy and Real-World MPG

The GLA35 is estimated to return 23 mpg city and 29 mpg highway, and the more powerful GLA45 is predictably thirstier, with ratings of 20 mpg city and 27 mpg highway. These efficiency numbers are similar to competitors such as the BMW X2 M35i and the Mini Cooper Countryman JCW. We haven’t had a chance to test drive the new GLA35 or GLA45 models yet our 75-mph highway fuel economy route. For what it’s worth, the X2 M35i managed an impressive 33mpg in the same test, and the last-generation GLA45 managed a 28mpg result.

Interior, comfort and cargo

The standard GLA-Class’s interior is more spacious for rear-seat riders than the last-generation model, and this also applies to the GLA35. The quality of interior materials has taken a step up, and the interior design is very similar to other recently launched Mercedes SUVs. Sporty front seats, red stitching, red seatbelts, a flat-bottomed steering wheel and carbon fiber interior trim all give the AMG version of the GLA-Class a more raucous vibe. Cargo space is slightly larger than the outgoing model’s, and the load floor is now flush with the sill for easier loading and unloading.

Infotainment and connectivity

Two giant 10.3-inch infotainment screens dominate the GLA-Class’ dashboard. One serves as a reconfigurable gauge display and the other handles the infotainment system. The interface contains Mercedes-Benz’s MBUX software, which offers the “Hey Mercedes” voice control system, but it can also be controlled via the touch screen or the touch panel mounted on the center console. The system includes Apple CarPlay and Android Auto capability as standard, but navigation costs extra.

Safety and Driver Assistance Features

A series of advanced driver assistance features is offered as part of the Driver Assistance Package, but automatic emergency braking is standard. For more information on the GLA-Class’ crash test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:

  • Standard automatic emergency brake
  • Available lane departure warning and lane keeping assist
  • Adaptive cruise control available

Warranty and Maintenance Cover

Basic warranty coverage of four years or 50,000 miles is included with the purchase of a new GLA-Class, but both the BMW and the Mini offers three years of complimentary scheduled maintenance.

  • Limited warranty covers four years or 50,000 miles
  • Powertrain warranty covers four years or 50,000 miles
  • No complimentary scheduled maintenance
