Engine Specs and MPG for the Mercedes-Benz GLB

The engine specs play a key role in the MPG specs for the Mercedes-Benz GLB compact SUV, so that’s where we’re going to start.

We love that this vehicle’s engine packs a powerful punch while still maintaining impressive efficiency ratings. Take a look at the engine specs below:

  • 2.0L turbocharged I-4
  • 221 horsepower
  • 258 lb-ft of torque

The tight ratio between horsepower and torque output creates balance and improves drivability, while still keeping this SUV on its toes. In fact, these specs can help you rocket from 0 to 60 MPH in as little as 6.9 seconds under the right conditions.

Your engine will be paired with an 8G-DCT 8-speed dual-clutch automatic transmission. With a dual-clutch transmission, you’ll get the best of both worlds: the smooth and optimized gear shifts of an automatic with the precision of not just one manual transmission, but two.

The transmission also includes DYNAMIC SELECT, which lets you tune the drivetrain, steering feel, and available adjustable suspension based on four different drive modes. Meanwhile, a semi-manual mode allows you to change gears on-demand. With these features, you always get the kind of drive you want.

Mercedes-Benz GLB MPG and Drivetrain

Drivetrain is definitely something that’s worth considering when you’re looking to maximize the MPG of the Mercedes-Benz GLB.

With this model, you’ll get your choice between two systems: front-wheel drive (FWD) and 4MATIC® all-wheel drive (AWD). Here’s how their MPG ratings measure up…

EPA-Estimated City MPG EPA-Estimated Highway MPG
Front-Wheel Drive 23 MPG1 30 MPG1
4MATIC® All-Wheel Drive 23 MPG1 31 MPG1

As you can see, both drivetrains achieve the same fuel efficiency during city driving. However, the AWD system can go ever so slightly farther on the highway. This may be due in-part to how smart this drivetrain system is.

4MATIC® AWD automatically adjusts torque distribution between the front and rear axles to optimize stability, handling, and efficiency based on your conditions. That includes lightening up during highway driving to allow for smooth cruising that may cut down on fuel use.

It also includes smart features, like loose-surface drive mode, that improves traction control while driving over dirt and sand. Meanwhile, Downhill Speed Regulation utilizes engine braking to automatically reduce speeds on downhill slopes.

For these reasons, the 4MATIC® AWD system tends to be a favorite feature upgrade for local drivers who want their luxury SUV to go anywhere and everywhere while still keeping MPG numbers high.
