  • X3 Engine comes with various models with 2.0l, 2.5l, and 3.0l engine capacity.
  • Power offered by this Engine varies from 288HP in 2l capacity engine to 503HP in 3l capacity engine.
  • X3 Engine is manufactured with 4 cylinders turbocharged engine and an inline 6 cylinders twin-turbocharged engine.
  • Torque produced is 310 ft-lb in 2l capacity engine and up to 442 ft-lb torque in 3l capacity engine. 

X3 Engine Strength

We are discussing from the beginning about popularity and the strength of the X3 Engine. As you might have got the idea through the specifications about the powerful X3 engine. But still, let’s discuss some key strengths of X3 Engine.

Output Power

The power of any engine can be measured by the efficiency of the combustion taking place inside the cylinder. As better combustion takes place, more energy will be produced to move the shaft and in turn, more power will be produced. In a 3l capacity engine, the power offered is more than 450HP. This much power can help to accelerate better at high speeds.


X3 Engine has 4 and 6 inline cylinders depending on the engine model. The more the number of cylinders, the less is the vibrations and ultimately high speed. This is the reason why BMW Engines are used in racing cars. 

Models Of X3 Engine 

There are several models of the BMW X3 Engine. N46, M54, and N52 engine models come in petrol, and M47, N47, and M57 come in diesel. Let’s discuss them in brief.

N46 Engine Model (Petrol)

It is a replacement of N42 Engine with revised features in valves and crankshaft. It is a 4-cylinder engine with and 2l capacity. 

N52/M54 Engine Model (Petrol)

Basically, M54 is the replacement of M52 and N52 is the replacement of M54. It gets quite confusing. But don’t worry, you just need to know that every replacement comes with some new features. Both N52 and M54 are 6-cylinder engines and N52 also comes with an electric water pump that helps to increase the power efficiency of the engine. The variations of N52 and M54 come with 2.5l and 3.0l capacity.

M47/N47 Engine Model (Diesel)

M47 and N47 both are diesel engines with 4-cylinder and 2l capacity. N47 is the replacement over M47 and has many advanced features comparatively. This engine mode got popular enough and BMW used it in other car models too.

M57 Engine Model (Diesel)

M57 is a replacement for the M51 model. It has inline 6-cylinders and 3l capacity. The improved Blocks and crankcase with a common rail system have helped the X3 cars to run faster with more power.

Maintenance of BMW X3 Engine

Car Engines require proper maintenance work. Even minor issues should not be avoided as they may lead to serious problems with time. Let’s discuss some points that can help you in car maintenance and can save you money and time. 

Engine Oil

For proper functioning of the engine, engine oil needs to be replaced timely as it is responsible for the internal combustion inside the cylinder. So, use only high-quality engine oil that will help you to increase the output power of the engine too.

Remember, you can get an idea if there is some issue with the engine by some disturbing noises.

Here is an article on Car Noise and its Indications for complete details.

X3 Engine Coolant 

If you don’t know, Car engines have a special coolant chamber to reduce the temperature inside. Because the combustion takes place at a very high temperature and it leads to abrasion of engine parts. So, car engine coolant requires proper maintenance work at regular intervals by adding an equal mixture of water and coolant. Avoiding this can lead to engine damage that can cost you a fortune.

Waste Removal

Car engines require deep internal cleaning. The combustion inside the chamber and other eroded parts contributes to the waste. There is a great importance of engine and transmission cleaning as it is one of the main reasons that affect the performance of the car.

Loose Piston Rings and Cables 

For better output of the X3 Engine, the combustion chamber needs to be totally sealed. But with time, the cables, valves, and piston rings get loose and start to tear. So, regular replacements and checkups are necessary for better engine performance.


BMW X3 is considered as one of the most premium SUVs manufactured. It is because of its overall performance and superior body look. As you know that BMW is out shadowing many big automobile companies just because of its base engine strength. The manufacturing of the BMW X3 engine had a great impact on the market as other top companies start using the BMW Engine in their cars. 

You can also buy the Used BMW Engines for your X3 if required. But used engines generally require more maintenance too. Just remember engine is the heart of the car. Any issue with the heart can lead to intense damage to the whole car. So don’t avoid any noises or issues if you want your car to run smoothly.
