Why it stands out

The 2021 Subaru WRX STI is a performance sedan that combines thrilling driving dynamics with everyday practicality. It is powered by a robust 2.5-liter turbocharged flat-four engine, delivering 310 horsepower and 290 lb-ft of torque, making it a top choice for enthusiasts seeking a spirited driving experience. The WRX STI's all-wheel-drive system enhances its handling capabilities, allowing it to tackle corners with precision and confidence. While it excels in performance, the ride can be harsh for daily commuting, which may deter some buyers. The interior, though functional, shows signs of age with a dated design and basic technology features. However, the aggressive styling, including a functional hood scoop and large rear wing, ensures it turns heads wherever it goes. Overall, the WRX STI is ideal for those who prioritize performance and are willing to compromise on comfort and modern tech.
