It is often equipped with turbocharging, allowing for quick throttle response and increased torque at lower RPMs. This engine is ideal for applications requiring quick acceleration and high-speed performance. The M276 engine also features advanced technologies such as direct fuel injection and variable valve timing, further improving efficiency and emissions control.

• M274 I4 Petrol Engine

  The M274 I4 petrol engine is a 4-cylinder engine designed for smaller, more lightweight versions of the Atego. This engine offers excellent fuel efficiency, making it suitable for applications focused on reducing operational costs and environmental impact. The M274 I4 petrol engine may also employ turbocharging, providing a smooth delivery of power and torque. Its smaller size and weight contribute to the overall agility and maneuverability of the vehicle, making it a perfect choice for urban logistics and distribution tasks.

• OM934 I4 BlueTec Diesel Engine

  The OM934 I4 BlueTec diesel engine is a 4-cylinder engine that is part of Mercedes-Benz's BlueTec technology. This technology aims to reduce emissions and meet stringent environmental standards. The OM934 engine is typically used in lighter versions of the Atego, offering a balance of power and efficiency for urban and regional distribution. The BlueTec system uses AdBlue, a urea-based solution injected into the exhaust system. This system converts harmful NOx emissions into harmless nitrogen and water vapor, ensuring cleaner and more efficient engine operation.

• OM936 I6 BlueTec Diesel Engine

  The OM936 I6 BlueTec diesel engine is a more powerful 6-cylinder engine commonly used in heavier versions of the Atego. It provides high torque, making it suitable for applications requiring heavy load capacity and towing ability. Like the OM934 engine, the OM936 engine also incorporates BlueTec technology for emissions control. The OM936 engine is designed for durability and reliability, essential for long-distance transportation and logistics operations. Its robust construction and advanced cooling and lubrication systems ensure optimal performance and low maintenance costs over the engine's lifespan.
