If you’re familiar with the brand, you may have already heard of Subaru’s famous Subaru Boxer. But what makes this engine so different from the others? Desjardins Subaru presents a complete guide to discover this ingenious technology and its many advantages.
What makes the Subaru BOXER engine unique?
The Boxer engine gets its name from its unique design: its pistons move horizontally and opposite, reciprocating face-to-face. The pistons are arranged symmetrically and at a flat 180-degree angle. This reproduces a movement similar to that of a boxer’s punches!
The invention was invented by German engineer Karl Benz in 1897. At Subaru, the development of the first Boxer engine dates back nearly 60 years.
At the time, Subaru’s research and development team was convinced that the inherent advantages of this type of engine made it the best choice. A unique solution emerged: using more expensive aluminum, which made it possible to make an engine block 15% lighter than other engines in the same class!
It was in 1966 that the Boxer engine was found for the first time at the heart of the Subaru 1000 EA 52. The sedan was then equipped with a 1.0 L engine developing 55 horsepower.
In 2008, the EJ25 turbo engine (the engine of the Subaru Impreza, Forester, Legacy and Outback) won the title of engine of the year! The direct injection Boxer engine of the WRX was also named among the 10 best engines by Wards in 2014 and 2016.
Several manufacturers have chosen the simplicity of traditional engines, but not Subaru. Indeed, the manufacturer continues to use this type of engine despite a more complex installation. As a result, Subaru engines are unique and recognized for their exceptional driving quality.
What are the benefits of Subaru BOXER engines?
A lower center of gravity
The horizontal arrangement of the pistons gives the engine a low and flat profile, which helps lower the center of gravity of the engine and the vehicle itself. When compared to V or inline engines, which are configured vertically, Boxer engines provide better cornering stability, more controlled road behavior and, as a result, much more driving fun.
Sharper handling
A lower center of gravity generally means a better driving feel, more contact with the road. This translates into better cornering stability, more responsive handling and better evasiveness. Vehicles equipped with Boxer engines offer you agile and confident road behavior.
Smoother acceleration
This type of engine is compact, lightweight and positioned symmetrically and low in the chassis, to ensure smoother and more direct power production. Accelerations are linear and responsive!
Better Performance Efficiency
The pistons move side by side, a more balanced configuration by nature, so they induce less vibration, generate better performance and reduce wear on moving parts.
Reduced Vibration
Because of their horizontal arrangement, each piston movement is counteracted by an opposing piston, naturally balancing the engine. This unique feature minimizes vibration, which means a quieter, more comfortable and, overall, much more enjoyable ride.
Better Power Transfer
Because the engine is aligned with the drive system, this results in optimal power transfer. Conversely, many engines are mounted transversely or perpendicularly, requiring additional components to transfer power. Subaru engine designs simplify the system and increase efficiency.
What is the impact of such an engine on performance and reliability?
The design of Boxer engines stands out in terms of road handling and performance, especially since they are combined with other advanced technologies such as symmetrical full-time all-wheel drive. All of this allows for great towing capacities for Subaru SUVs.
As for reliability, the performance efficiency of Subaru engines reduces wear on parts, ensuring a longer lifespan. While they do not require more maintenance than any other type of engine, they are nonetheless complex.
Since they are rarer, it is best to entrust their maintenance and repairs to professionals who know them well. Who better than certified Subaru technicians to take care of a Subaru engine?
Which models are equipped with the Subaru BOXER engine?
Today, all models offered by Subaru Canada are equipped with Boxer engines, except for the Solterra electric SUV. The Japanese manufacturer has developed a varied range of naturally aspirated or turbocharged engines.
The Subaru Ascent, Legacy, Outback (optional) and WRX are equipped with a 2.4 L turbocharged engine. To maximize its performance, the WRX uses a twin-scroll turbocharger and a high-efficiency intercooler.
As for the Subaru Crosstrek and Impreza engine, you can opt for a 2.0 L or a 2.5 L, both naturally aspirated, for a power of 152 or 182 horsepower respectively.
Does the Subaru BOXER engine have a greener impact than other traditional engines?
Yes, and this is especially true with the latest generation of engines. Thanks to their efficiency, their power transfer and their optimal engine power curve, they are able to produce more power with less oil than other traditional engines.
Indeed, Subaru has been able to eliminate various types of energy losses over the years in order to achieve better energy efficiency. As we mentioned, these engines are lightweight and reduce the number of components compared to vertical layouts! This helps reduce the consumption of cars, but also of Subaru SUVs.
In short, the Boxer engine stands out with its unique design, which prioritizes driving pleasure and comfort. Whether you prefer a sports car, sedan or SUV, enjoy all the advantages of this engine with one of our models and get a good deal with our Subaru offers.
