GLA vs. GLB: Starting Price

While these SUVs are close in price, Alamo Heights drivers will spend less on the latest GLA SUV. Explore the starting prices for each vehicle below:

  • 2022 Mercedes-Benz GLA SUV Starting Price: $36,400 MSRP*
  • 2022 Mercedes-Benz GLB SUV Starting Price: $38,600 MSRP*

GLA vs. GLB: Passenger & Cargo Space

With the latest GLB, you can opt for the optional third-row seating for accommodation for up to seven adult passengers in total. The GLA, however, only seats five, which is often a major deciding factor for many shoppers comparing the Mercedes-Benz GLA vs. GLB.

The GLB is longer from end to end, so it’s not surprising that it can accommodate more cargo:

  • GLA Cargo Volume (All Seats Flat): 50.5 cubic feet
  • GLB Cargo Volume (All Seats Flat): 62 cubic feet

GLA vs. GLB: Fuel Economy and Ride Quality

As mentioned above, both of these compact SUVs feature a 2.0L inline-4 turbo engine as a standard. The powerful engine delivers 221 hp and 258 lb-ft of torque, which means it is an excellent SUV for daily drivers around the Shavano Park and Hollywood Park areas.

When it comes to performance, both are evenly matched. However, there are a few subtle differences to know before visiting our San Antonio Mercedes-Benz dealership for a test drive:

  • The GLA gets up to 34 mpg on the highway, compared to 32 mpg for the GLB. As a result, the GLA may cost less to own.
  • With that said, the GLB holds about 3.2 more gallons of fuel than the GLA. This means it can go farther on a single tank of gas.
  • For a smoother ride, the GLB offers a longer wheelbase: 111.4 inches vs. 107.4 inches for the GLA. Vehicles with longer wheelbases are better at absorbing cracks and bumps in the road.
