How much HP does a factory WRX have?
The factory Subaru WRX comes equipped with a turbocharged 2.4-liter boxer engine that produces around 271 horsepower. This power output is the result of Subaru's engineering efforts to deliver a high-performance sports sedan that balances power, drivability, and efficiency.
Subaru WRX Engine Specifications
The Subaru WRX is powered by a 2.4-liter turbocharged BOXER engine, which is a horizontally-opposed four-cylinder design. This engine features direct fuel injection, a twin-scroll turbocharger, and Subaru's Dual Active Valve Control System (DAVCS) to optimize power and efficiency.
- Engine Displacement: 2.4 liters
- Engine Configuration: Horizontally-opposed 4-cylinder (BOXER)
- Turbocharger: Twin-scroll
- Horsepower: 271 hp @ 5,600 rpm
- Torque: 258 lb-ft @ 2,000-5,200 rpm
The combination of the turbocharged BOXER engine and Subaru's Symmetrical All-Wheel Drive system gives the WRX impressive performance and handling capabilities.
Factors Affecting WRX Horsepower
While the factory WRX produces 271 horsepower, there are a few factors that can influence the actual horsepower output:
- Drivetrain Losses: Some power is lost through the drivetrain components, such as the transmission and differentials, before it reaches the wheels. Typical drivetrain losses can be around 10-15% of the engine's output.
- Environmental Conditions: Factors like altitude, temperature, and humidity can affect the air density and impact the engine's power output. Higher altitudes, for example, can reduce power by 3-5% per 1,000 feet of elevation.
- Modifications: Aftermarket upgrades like a high-flow exhaust, cold air intake, or engine tuning can increase the WRX's horsepower beyond the factory rating.
It's important to note that the horsepower figures provided by Subaru are based on standardized testing conditions, and real-world performance may vary slightly depending on the specific factors mentioned above.
