Performance & Efficiency
The mechanical core of the 2026 GLB 250 is defined by a highly efficient 2.0-liter turbocharged four-cylinder engine. This powerplant is engineered to provide a spirited driving experience, generating 221 horsepower and 258 lb-ft of torque. This output ensures that merging onto busy thoroughfares or navigating the gentle inclines found throughout Georgetown remains effortless and refined. Power is managed through a sophisticated 8-speed dual-clutch automatic transmission that offers rapid, seamless gear changes, optimizing both acceleration and fuel economy.
Drivers can further tailor the vehicle's behavior using the DYNAMIC SELECT system. This feature allows for the adjustment of throttle response, steering weight, and shift points through various modes, such as Eco, Comfort, and Sport. For those who prioritize maximum grip during inclement weather, the available 4MATIC all-wheel-drive system continuously monitors traction and redistributes power to the wheels with the most purchase on the road.
Efficiency remains a hallmark of this model's engineering. The front-wheel-drive configuration achieves an impressive 33 MPG on the highway, resulting in a balanced combined rating for daily use. Selecting the all-wheel-drive variant increases the vehicle weight to 3,759 pounds but maintains strong efficiency figures, ensuring that performance does not come at the cost of frequent refueling stops.
