M270 Mercedes Engine
- The Mercedes M270 engine is a turbocharged inline-4 engine introduced by Mercedes-Benz in 2012. It’s part of the M270/M274 engine family and was primarily developed for transverse-mounted applications in front-wheel-drive and all-wheel-drive vehicles. This engine is known for its blend of performance and efficiency, featuring direct fuel injection, variable valve timing, and a twin-scroll turbocharger.
M270 Mercedes Engine Overview
The M 270 engine series has a displacement of 1.6 liters and was designed for transverse installation. There are two power versions: 90kW and 115kW. This new engine family replaces the highly successful M 266 engine series. The new direct injection system combines a very fast and precise injector with a new jet-guided combustion process. The M 270 engine series allows for compliance with increasingly stringent CO2 limits, while also achieving high power and torque outputs, as well as particularly comfortable levels of vibration and noise emissions. The use of flexible technology modules helps to reduce consumption and gross emissions. This not only meets various legal and commercial requirements worldwide but also ensures the future viability of this engine family.
M270 Engine Reliability
- The M270 engine is generally considered reliable, especially when properly maintained. However, like any modern engine, it has specific maintenance requirements that must be followed to avoid common issues. Regular oil changes, using the correct grade of oil, and keeping up with scheduled maintenance can significantly extend the life of the M270 engine.
Mercedes M270 Engine Problems
- Some common issues reported with the M270 engine include:
- Timing Chain Wear: Over time, the timing chain may stretch or wear, leading to potential misalignment issues or engine noise.

Mercedes M270 Engine Oil Capacity
- The oil capacity of the M270 engine typically ranges between 5.5 to 6.0 liters, depending on the specific model and year. It is crucial to use the recommended oil type and follow the manufacturer’s guidelines for oil changes to maintain engine health.
M270 Engine Thermostat
- The thermostat in the M270 engine plays a critical role in regulating engine temperature. A faulty thermostat can lead to overheating or insufficient heating, which can cause engine damage. It’s recommended to replace the thermostat if any signs of failure appear, such as fluctuating engine temperatures or coolant leaks.
Mercedes M270 vs M274
- While the M270 and M274 engines share a lot of similarities, the key difference is in their application. The M270 is used in transverse-mounted setups (front-wheel-drive), while the M274 is used in longitudinal-mounted setups (rear-wheel-drive). The M274 also tends to have slightly different tuning, with variations in horsepower and torque outputs depending on the specific model.
Which Mercedes Models Are Equipped with the M270 Engine?
- The M270 engine is found in several Mercedes-Benz models, including:
- Mercedes-Benz A-Class (W176)
- Mercedes-Benz B-Class (W246)
- Mercedes-Benz CLA-Class (W117)
- Mercedes-Benz GLA-Class (X156)
Is the M270 Engine Good?
- Overall, the M270 engine is a solid choice for those seeking a balance of performance and fuel efficiency in a compact engine. It has proven to be reliable for the most part, especially with proper maintenance. The engine’s design focuses on delivering strong performance while meeting stringent emissions standards, making it a good fit for modern Mercedes-Benz vehicles.
