The 2009 Ford Focus RS is powered by a 2.5-liter turbocharged inline-five engine, delivering about 300 horsepower and 440 Nm of torque, paired with all-wheel drive for strong, planted performance.
Beyond that concise answer, this article takes a closer look at the engine’s origins, configuration, and how it defined the Focus RS’s distinctive performance in the late 2000s. The Mk II Focus RS used a turbocharged five‑cylinder from Ford’s Duratec family, with development work tied to Volvo’s five‑cylinder heritage to create a compact, high-revving powerplant that sounded and behaved like a rally-inspired machine.
Engine details
The heart of the Focus RS Mk II is Ford’s 2.5-liter turbocharged inline-five, a member of the Duratec family that borrows lineage from Volvo’s five-cylinder engines and is tuned specifically for high-performance use.
Below are the core specifications and features that defined the engine in the 2009 Focus RS.
- Configuration and displacement: 2.5-liter (2,496 cc) turbocharged inline-five (I5).
- Valvetrain: DOHC with 4 valves per cylinder (20 valves total).
- Turbocharging and induction: single turbocharger with air-to-air intercooling.
- Power output: approximately 300 PS (around 296 horsepower) at about 6,000 rpm.
- Torque: around 440 Nm (325 lb-ft) peak, typically developed around 3,000–4,000 rpm.
- Transmission: six-speed manual gearbox.
- Drivetrain: intelligent all-wheel drive system (Haldex-based), with a variable torque split for enhanced traction.
In summary, the engine blends a compact turbocharged five-cylinder layout with Ford’s performance-oriented AWD, creating the distinctive performance character of the 2009 Focus RS.
Performance and drive characteristics
With the 2.5-liter turbo I5 at its core, the Focus RS delivers strong acceleration and confident handling, aided by a short-throw manual and a traction-biased all-wheel-drive system. The engine’s torque comes on strongly in the mid range, and the boost from the turbo helps the car sprint from standstill with notable immediacy.
Performance figures vary by market, but commonly cited numbers place the 0–60 mph time around 5.9 seconds and a top speed near 165 mph (depending on gearing and market). The engine’s distinctive soundtrack and strong mid-range torque contribute to the RS’s rally-inspired character and everyday usability alike.
Maintenance and reliability notes
Owners of the 2009 Focus RS generally report robust performance when the car is properly maintained. Regular service with quality components, attention to cooling and intake cleanliness, and timely turbo/intercooler checks help sustain performance and reliability. Because the engine shares parts with Ford’s Duratec line and Volvo’s five-cylinder family, parts availability remains reasonable in many markets, and there is a broad aftermarket for maintenance and upgrades.
Summary
The 2009 Ford Focus RS uses a 2.5-liter turbocharged inline-five (Duratec-based) producing about 300 PS and 440 Nm of torque, paired with intelligent all-wheel drive. This combination gave the RS its distinctive, rally-inspired performance, blending lively high-rev behavior with strong mid-range grunt and confident traction across diverse driving conditions.
