Mercedes Introduces Turbo Electric Engine to GLB Model
Written with artificial intelligence.

Mercedes has unveiled the new M252 LS engine, featuring a 48-volt electric turbocharger that enhances response time and reduces CO₂ emissions by 17%. This technology, derived from Formula 1, is set to debut in the GLB 250 model, offering improved acceleration and efficiency.
Overview of the New M252 LS Engine
Mercedes has integrated cutting-edge technology from Formula 1 into its new M252 LS engine, a 1.5-liter turbocharged four-cylinder powertrain. This development promises to deliver a quicker throttle response while reducing fuel consumption. The engine produces 231 hp (170 kW) and is complemented by an additional 31 hp (23 kW) from its electric turbocharger.
Key Features of the Electric Turbocharger
The M252 LS features an innovative electric turbocharger powered by a 48-volt system. This setup allows the turbo to reach optimal pressure without the delay commonly associated with traditional turbo lag. The electric compressor not only enhances acceleration but also contributes to improved energy management by generating electricity from the exhaust flow.
Benefits of the New Technology
- Enhanced Throttle Response: The electric system provides immediate response across the engine's operating range.
- Reduced Emissions: Mercedes claims a 17% decrease in CO₂ emissions compared to the previous engine model.
- Improved Performance: The GLB 250 equipped with this engine shows a reduction in acceleration time by approximately one-tenth of a second compared to its predecessor.
Engineering Collaboration
This innovative engine technology is a product of collaboration with Mercedes-AMG High Performance Powertrains, the team responsible for developing Formula 1 power units. Mercedes emphasizes that this transfer of technology involves more than just component swaps; it encompasses the sharing of expertise and development methodologies tailored to everyday vehicle needs.
The M252 LS engine represents a significant step in Mercedes' commitment to combining performance with efficiency, showcasing the practical applications of motorsport technology in consumer vehicles.
