What Are the Key Differences Between WRX and STI?

When comparing the WRX to STI, several key differences emerge that make the STI the superior choice for those craving a high-performance vehicle. These differences span across engine power, drivetrain configurations, suspension, and interior features. The WRX is no slouch, offering a turbocharged 2.0-liter engine with 268 horsepower. However, the STI ups the ante with its 2.5-liter turbocharged engine delivering a robust 310 horsepower.

The STI also includes advanced features like a Driver Controlled Center Differential (DCCD) system, allowing you to adjust torque distribution between the front and rear wheels. This is a game-changer for anyone seeking greater control during spirited driving sessions. Additionally, STI models boast Brembo brakes, reinforced suspension, and a more aggressive exterior design.

Interior-wise, the STI offers superior materials, bolstered seats for better support during high-speed maneuvers, and exclusive badging that adds a touch of exclusivity. While the WRX provides a balanced mix of comfort and performance, the STI is unapologetically performance-oriented.

Why Choose STI Over WRX?

For drivers who prioritize track performance, enhanced handling, and premium features, the STI is the clear winner. While the WRX is an excellent entry point, the STI caters to a more performance-focused audience. The choice ultimately boils down to what you value most in a vehicle.

Key Specifications at a Glance
