Boxer engines derive several performance advantages inherent to their design, since the center of gravity on an opposed engine is much lower to the ground compared to an in-line or V design. This allows for better lateral acceleration. In addition, the benefits to handling are enormous.
What is the advantage of a boxer engine?
The advantage of a boxer engine is that the engine counter balances itself. The pistons that are across from each other move toward the crank and away from the crank at the same time. This gives smoother operation and a crank shaft that is lighter because no counter balance weights are required.
Why are boxer engines bad?
The downside of a boxer engine from a balance perspective is that pistons don’t sit directly across from one another, meaning they can create a torque that tends to want to rotate the engine about the vertical axis.
Is a boxer engine reliable?
Due to the low, wide mount, the boxer engine can prove difficult to service. Even changing spark plugs can be a substantial job. However, boxer engines are known for their reliability, and should require less service than most other engine types.
Is Boxer engine better than inline?
Inline engines feature pistons that sit upright and move straight up and down. This means the engine block is taller overall and has a higher center of gravity than a SUBARU BOXER® engine, which features pistons laid flat. The upright layout of inline engines means they can vibrate more during operation.
What are the disadvantages of a boxer engine?
Boxer engines offer the benefit of a low centre of gravity and perfect balance. The disadvantages of the boxer engine include the engine size and the difficulty of maintenance.
Are boxer engines more powerful?
Boxer engines derive several performance advantages inherent to their design, since the center of gravity on an opposed engine is much lower to the ground compared to an in-line or V design. … Lower profile also makes power transmission more even, as the engine is on a plane closer to the rest of the drive-train.
Do Subaru engines last long?
They can last forever if you take care of them, even if you abuse it, expect it to go past what you’d expect. At 100k+ once the head gaskets (timing belt etc.) have been replaced and that mess has been fixed, the thing is basically good for another 100-200k.
Is the Subaru boxer engine a Porsche?
Subaru is the only automaker on the planet that uses the boxer engine in its entire lineup. They use it in the Forester, Outback, Crosstrek, Impreza, WRX/STI, Legacy and BRZ. Porsche is the only other automaker that uses the flat, H-shaped, opposed-piston “boxer” engine. It’s a good design and it’s winning awards.
Why do Subaru engines fail?
Subaru engines hate running low on oil. They are finicky. Unlike a Honda that can keep going on drops of oil like an anorexic chick on crumbs, running a Subaru engine low on oil alone can make your engine fail. Volume is important, but so is the quality of oil you are using.
Why are Subarus so unreliable?
One of the core reasons that Subaru reliability has dropped is due to the problems that the Outback and Legacy have had with in-car technology. This is a common reason for declining dependability in a number of makes and models since the early 2000s. Many cars today have a great deal of new and complex technology.
Do Subarus have alot of problems?
In 2016, Subaru scored a total VDS ranking of 166 (Problems per 100 Vehicles), in 2017, the Japanese automaker ranked 164 PP100 well below the industry average of 156. In 2018, Subaru slipped into the bottom quarter of all automakers with a 167 PP100 while the overall industry average improved 9 percent to 142.
Which Subaru engines to avoid?

Is a boxer engine a flat 4?
The most common type of flat-four engine is the boxer-four engine, each pair of opposed cylinders moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however the two cylinder heads means the design is more expensive to produce than an inline-four engine.
Why do boxer engines burn oil?
Boxer engines can burn more oil. Oil more easily pools in the cylinder heads and can leak into the cylinder. Likewise, oil finds its way to the bottom of the cylinder and stays there longer vs gravity taking it down past the rings.
