When you hear about a boxer engine, you might wonder: what is it? And which cars use it? This article will explain everything about boxer engines in a simple way. You will learn why some cars have them and why they are special.
What Is a Boxer Engine?
A boxer engine is a type of engine that works differently than most engines.
- It has cylinders that lie flat and face each other.
- The pistons move side to side, like boxers punching.
- This is why it is called a “boxer” engine.
Because the pistons move in opposite directions, the engine stays very balanced. This helps the car run smoothly.
How Does a Boxer Engine Work?
In a boxer engine:
- Two cylinders are on the left side.
- Two cylinders are on the right side.
- They move in and out at the same time but opposite directions.
This side-to-side motion lowers engine vibrations. It also helps the car stay steady on the road.
Why Do Some Cars Use Boxer Engines?
There are many reasons why car makers choose boxer engines. Here are the main ones:
1. Low Center Of Gravity
The flat design of boxer engines helps keep the engine low in the car. This lowers the center of gravity.
A low center of gravity means:
- The car handles better in turns.
- It feels more stable and safe.
2. Smooth Performance
The opposite piston movement balances the engine well. This reduces shaking and vibrations.
Because of this, cars with boxer engines often have a smooth ride.
3. Compact Size
Boxer engines are usually shorter in length than inline engines. This makes it easier to fit them in small engine bays.
This helps car makers design better cars with more space for passengers.
4. Strong And Durable
Boxer engines are known to last a long time. Their design spreads out engine forces evenly.
This lowers wear and tear on engine parts.
Which Cars Have Boxer Engines?
Not many car brands use boxer engines. But some famous ones do:
| Car Brand | Examples of Models | Reason for Using Boxer Engine |
|---|---|---|
| Subaru | Impreza, Outback, Forester, WRX | Better stability, handling, and safety in all-wheel-drive cars. |
| Porsche | 911, Cayman, Boxster | High performance and low center of gravity for sports cars. |
| Toyota | Some sports models (like the 86) | Sporty handling and balanced weight distribution. |
Why Does Subaru Use Boxer Engines?
Subaru is famous for using boxer engines in almost all their cars. Here is why:
- It helps keep the car stable on rough roads.
- It fits well with Subaru’s all-wheel-drive system.
- It makes the car safer by lowering the center of gravity.
Subaru drivers often say the ride feels smooth and steady, even in bad weather.
Why Does Porsche Use Boxer Engines?
Porsche uses boxer engines for different reasons:
- They want a low and wide engine for better car balance.
- This helps their sports cars stay stable at high speeds.
- Boxer engines also allow for a unique sound that many Porsche fans love.
Advantages of Boxer Engines
Here are the main advantages:
- Better Balance: Less shaking and vibration.
- Lower Center of Gravity: Improved car handling.
- Compact Design: Fits well in many car designs.
- Durability: Engine parts last longer.
- Unique Sound: Some drivers love the boxer engine noise.
Disadvantages of Boxer Engines
But boxer engines are not perfect. Here are some drawbacks:
- Wide Engine: Can be too wide for some car designs.
- More Complex: Two cylinder heads mean more parts.
- Cost: Usually more expensive to build and repair.
- Exhaust System: Needs a longer exhaust pipe to work well.

Why Don’t More Cars Use Boxer Engines?
Many car makers prefer other engine types. Here’s why:
- Boxer engines are wider, so they do not fit all cars.
- They can be more expensive to make and fix.
- Inline and V engines are easier to design and produce.
- Boxer engines are best for certain cars, like sports or AWD vehicles.

Summary
Boxer engines are special because of their flat design and piston movement. They help cars stay balanced and stable. Subaru and Porsche are the main car brands that use them.
These engines have many good points, like smooth rides and good handling. But they also have some problems, like being wide and costly.
In short, boxer engines fit well in some cars, but not all. That is why you see them in only a few brands.
Now you know why some cars have boxer engines and why they matter. Next time you see a Subaru or Porsche, remember the special engine inside.
Frequently Asked Questions
Is Subaru The Only Car With A Boxer Engine?
Subaru is not the only car with a boxer engine. Porsche and Toyota also use boxer engines in some models.
Which Toyota Uses A Boxer Engine?
Toyota uses a boxer engine in the Toyota 86 sports car. It shares this engine with Subaru BRZ, featuring a flat-four layout for better balance and handling.
What Are The Drawbacks Of A Boxer Engine?
Boxer engines have extra width, increasing vehicle design challenges. They cost more due to dual cylinder heads. Exhaust manifolds need to be longer for balanced pulses. This leads to higher manufacturing and maintenance expenses compared to inline engines.
What Does Boxer Mean In Cars?
A boxer engine in cars features horizontally opposed pistons moving side-to-side. This design improves balance, stability, and handling. Subaru and Porsche commonly use boxer engines for enhanced performance and efficiency. The layout lowers the center of gravity, resulting in better driving dynamics and smoother operation.
