The 2022 Mercedes-Benz AMG GLB35 4matic’s 22 MPG combined fuel economy reveals its priorities. It’s about performance, practicality, and a certain swagger in a compact SUV. The AMG GLB35 appeals to someone who needs cargo space and a small SUV with an available third row, but doesn’t want to sacrifice driving enjoyment for efficiency. They appreciate the AMG-tuned engine, suspension, and styling, and will pay for it at the pump.

City and highway performance

The EPA estimates 20 MPG in the city and 27 MPG on the highway for the AMG GLB35. The city figure reflects urban driving’s stop-and-go nature, where the turbocharged 2.0L engine’s responsiveness is constantly called upon, and the responsive AM8 transmission keeps the engine in its optimal zone. The highway number is likely achieved under ideal conditions, but expect that highway MPG to drop considerably if you regularly use the vehicle’s power. This vehicle encourages spirited driving, so restrain your right foot to get closer to the EPA’s projections.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Mercedes-Benz AMG GLB35 at $2,650. This is based on driving 15,000 miles per year, using premium gasoline at a national average price. If you drive more than 15,000 miles, or live in areas with higher fuel costs, expect a higher annual expenditure. The turbocharged engine requires high octane to deliver advertised performance, and skimping on fuel grade is not recommended.

Real-world expectations

Real-world fuel economy often differs from the EPA’s benchmark, so expect to see figures slightly below the official numbers if you embrace the AMG GLB35’s spirited side. Factors like driving style, traffic conditions, and even tire pressure can impact fuel consumption. A lead foot will certainly result in lower numbers, and consistent use of launch control will bring the MPG down significantly.

How it compares

The AMG GLB35 occupies a somewhat unusual niche compared to its competitors. The BMW X2 M35i, another performance-oriented subcompact SUV, achieves around 25 MPG combined, giving it a slight edge in fuel efficiency. The Audi SQ5 delivers a combined 21 MPG figure with significantly more power, so the GLB35 might seem like a good compromise to some buyers. Buyers may also consider the non-AMG GLB 250, which offers significantly better fuel economy (around 26 MPG combined) but sacrifices performance. The AMG GLB35 buyer accepts a compromise in fuel economy for the AMG enhancements and wants a more practical and versatile vehicle.

Tips to maximize efficiency

Maintaining proper tire inflation is important in maximizing fuel efficiency. Check your tire pressures regularly and inflate them to the recommended levels (found on the door jamb sticker). Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel.

Avoid aggressive acceleration and braking. Anticipate traffic flow and maintain a steady speed whenever possible. The AMG GLB35’s responsive powertrain is tempting to exploit, but smooth, consistent driving habits will make a noticeable difference at the pump.

Reduce unnecessary weight inside the vehicle. Extra cargo adds to the vehicle’s overall mass, increasing fuel consumption. Remove any items you don’t regularly need to lighten the load. Don’t carry unnecessary items in the top cargo carrier, especially at high speeds.

Consider using the GLB35’s “Comfort” driving mode for everyday commuting. While “Sport” and “Sport+” modes enhance performance, they also prioritize throttle response and shift points that can negatively impact fuel economy. Comfort mode delivers a more relaxed driving experience and optimizes fuel efficiency.
