STI vs Focus RS: Rally-Bred Rivals
Subaru STI vs Ford Focus RS comparison. Japanese heritage vs American interpretation of rally DNA.
Rally-bred AWD rivalry: Subaru's legendary STI versus Ford's Focus RS. Both channel their rally heritage, but which delivers the better real-world experience?
Detailed Comparison
Rally Heritage
Subaru WRX STI:
Three decades of WRC dominance define the STI. The EJ257 engine, while aged, carries immense tuning potential. The brand synonymous with rally performance.
Ford Focus RS (Mk3):
Ford's return to the hot hatch segment channeled RS200 and Escort Cosworth heritage. The 2.3L EcoBoost shares its heart with the Mustang, tuned for torque.
Power & Delivery
STI (EJ257 2.5L Turbo):
310 hp and 290 lb-ft. The high-revving, laggy character of the EJ257 rewards patience. Peak power at 6,000 RPM requires commitment. Sounds like nothing else—the boxer rumble is iconic.
Focus RS (2.3L EcoBoost):
350 hp and 350 lb-ft. More power, more torque, delivered earlier in the rev range. Overboost function provides brief surges. The EcoBoost is a more modern, responsive engine.
Advantage: Focus RS - Significantly more powerful and tractable.
All-Wheel Drive
STI:
Driver-controlled center diff (DCCD) allows manual torque split adjustment. Mechanical feel with genuine driver involvement. Legendary in poor conditions.
Focus RS:
GKN rear-drive unit with twin clutch packs. "Drift Mode" purposely overdrives the rear. More technology, but the hardware can overheat under sustained use.
Advantage: STI - More robust, driver-focused system.
Practicality
STI:
Sedan or hatchback (in some markets). Reasonable back seat, adequate trunk. Aged interior by modern standards but functional.
Focus RS:
Hatchback only. More modern interior but firm Recaro seats. The ride quality is harsh—the RS is not a comfortable car.
Advantage: STI - More comfortable daily driver.
