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.
Why are boxer engines bad?
On one hand, the boxer engines provide an unmatched performance to a sports car. However, the wide configuration makes it a bit hard to work on these mechanically. Besides, the obstruction of airflow they create in the engine area might even lead to their failure at high speeds.

Is a boxer engine balanced?
Boxer engines have low vibrations, since they are the only common configuration that have no unbalanced forces regardless of the number of cylinders. Boxer engines therefore do not require a balance shaft or counterweights on the crankshaft to balance the weight of the reciprocating parts.
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. … Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft.
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.
