Have you ever wondered what lies beneath the sleek exterior of a Subaru car? Subaru cars are made of different components and systems that are carefully designed and engineered to work seamlessly together. From the raw power generated within the engine to the finely tuned mechanics of the exhaust system, every facet of a Subaru vehicle plays a crucial role in shaping its performance, reliability, and distinctive driving experience. Let’s explore some important parts of a Subaru, from the engine to the exhaust.
The engine is the heart of the vehicle and provides the power necessary for its operation. Subaru engines are often horizontally opposed (boxer) engines, where the cylinders are arranged in a flat layout. This design helps lower the vehicle’s center of gravity and contributes to better balance and stability. Subaru engines also typically feature technologies such as Subaru’s Symmetrical All-Wheel Drive system and Subaru Intelligent Drive (SI-DRIVE), which work in harmony with the engine to optimize traction and control.
Subaru vehicles often come with a variety of transmission options, including manual transmissions and continuously variable transmissions. The transmission transfers power from the engine to the wheels, allowing the vehicle to change speed and direction.
The differential is a part of the drivetrain that allows the wheels to rotate at different speeds while maintaining power distribution. Subaru’s Symmetrical All-Wheel Drive system helps ensure power is distributed evenly between all four wheels for better traction and handling.
Subaru’s suspension systems comprise key components like shock absorbers, control arms, struts, springs, sway bars, and bushings. These elements collaborate to provide stability, and help to absorb shocks and vibrations from the road, providing a smooth and controlled ride. The symmetrical all-wheel-drive system and features like Active Torque Vectoring further contribute to precise cornering and adaptable traction, ensuring a balanced ride on a variety of terrains.
Subaru vehicles are equipped with disc brakes on all four wheels for effective stopping power. The brake system includes components like brake calipers, brake pads, and brake rotors.
Driveshaft and Axles
The driveshaft transfers power from the transmission to the differential or directly to the wheels. Axles transmit power from the differential to the wheels. Subaru’s Symmetrical All-Wheel Drive system uses a balanced design to optimize power distribution.
The electrical system includes the battery, alternator, starter, and various sensors. It powers the vehicle’s electrical components, such as lights, infotainment, and climate control systems.
The fuel system delivers fuel from the tank to the engine, where it is mixed with air and burned to produce power. Components include the fuel tank, fuel pump, fuel injectors, and fuel lines.
The cooling system prevents the engine from overheating. It includes the radiator, thermostat, water pump, and coolant. Subaru vehicles often employ a horizontally opposed engine layout for efficient cooling.
The steering system allows the driver to control the direction of the vehicle. Subaru’s vehicles use various steering mechanisms, including rack-and-pinion and electric power-assisted steering systems.
Oil Circulation System
Engines require lubrication to reduce friction and heat. The oil circulation system, including the oil pump, lubricates various engine components, ensuring smooth operation and longevity.
The exhaust systems consist of components like the exhaust manifold, catalytic converter, muffler, exhaust pipes, and oxygen sensors. These parts work together to expel exhaust gases, reduce noise, and enhance engine performance. The system ensures efficient emissions control and optimal engine operation, while sport-tuned variations in certain models may offer a distinctive and dynamic exhaust note, further enhancing the driving experience.
