Ford Focus RS (Mk2)

The Focus RS Mk2 made front-wheel-drive torque the story

The Ford Focus RS Mk2 is a brawny front-wheel-drive hot hatch built around a five-cylinder turbo engine. Our catalogue uses the 2009–2011 production window: a 2521 cc 2.5-litre turbo inline-5 with 301 bhp, 440 Nm, 0 to 100 km/h in 5.9 seconds and a 263 km/h maximum. We have not driven this model for this article. This is a desk-researched ownership guide using a Drive reproduction of Ford's 2009 Focus RS technical release, the PistonHeads Focus RS Mk2 used buying guide and the DVSA recall service. Their evidence should shape an inspection, not replace one.

Drive's Ford material confirms 305 PS, 440 Nm, 0 to 62 mph in 5.9 seconds and a 263 km/h maximum, with RevoKnuckle front suspension and a Quaife differential. PistonHeads records 305 hp, 11,500 built and about 4,000 UK cars, while also noting the more exclusive RS500 as a separate derivative. Our catalogue uses 301 bhp, the metric conversion of the cited 305 PS figure. That is the right anchor for comparing cars, but the exact market and equipment should still be verified from the VIN and paperwork.

The early plenum issue is a known file check

The Mk2 RS has a strong engine, but early cars are linked with a plenum issue that should be checked through service history and technical evidence. Ask whether the car has had related intake or engine work and whether any repair was completed by a Ford or specialist garage. A complete file is important because the issue is well known enough to affect confidence and value. Beyond that, inspect the turbo system, intercooler pipes, boost hoses, vacuum lines and intake tract for leaks, repairs and aftermarket parts.

The 2.5-litre five-cylinder engine should start cleanly, idle smoothly and pull without smoke or hesitation. Listen for turbo whine, boost leaks and exhaust blow. Check oil-change history, coolant condition, spark plugs, coil packs and evidence of remapping. The Mk2 RS is powerful and easy to tune, so Mountune upgrades and other packages are common. A documented upgrade can be a positive if it has been installed properly. Undisclosed mapping, a noisy turbo, weak clutch or repeated engine faults should lower the car's value until diagnosed.

Differential, RevoKnuckle and tyres manage the power

The Mk2 RS makes a lot of torque through the front wheels, so its front-end hardware matters. The RevoKnuckle system and Quaife differential should be present and functioning. On the test drive, the car should accelerate without violent torque steer, wander under power or clunk through the drivetrain. The gearbox should shift cleanly and the clutch should bite without slip. Ask about clutch, flywheel and gearbox work, because tuning and hard use can shorten their life.

Tyres are especially important. PistonHeads notes tyre wear, and the car's performance can make uneven wear obvious. Check for inner-edge wear, mismatched brands, wrong sizes and evidence of aggressive geometry. Wheels should be correct and undamaged. The suspension should feel controlled but not crashy; listen for knocks from dampers, top mounts and anti-roll-bar links. The steering should be accurate and free from excessive self-centering issues or vibration under braking.

The Mk2 RS is also a car where small symptoms can point to larger running costs. A whine under load may be turbo or driveline related, a clonk over bumps may be suspension or engine-mount related, and a strong smell of fuel should be investigated before purchase. Check the air-conditioning system, central locking, windows and audio, because a performance hatch is still used as a car and electrical faults affect daily satisfaction. If the seller has fitted coilovers, ask why and whether the original suspension is available. A lowered car may suit the model, but it should not be used to hide worn standard parts. Ask for a pre-purchase inspection if the car has been tuned, resprayed or recently returned to standard, because those are precisely the cars where hidden wear can survive a polished advert. A road test should include a cold start, a full-throttle pull in a safe gear, low-speed manoeuvring and a long enough run for the cooling fans and clutch to show their behaviour. If the seller cannot provide a calm explanation for warning lights, uneven tyres or replacement panels, walk away rather than trying to price every unknown.

Corrosion, body panels and RS identity are part of the value

The Focus RS Mk2 is old enough for corrosion to matter but modern enough for sellers to describe problem areas casually. Check arches, sills, underbody seams, subframe areas, brake lines and the condition of the rear bumper and spoiler mounts. PistonHeads mentions corrosion and spoiler rattle. Fresh underseal should be treated as a question, not a comfort, because hidden rust is more expensive than cosmetic wear. Panel condition should be consistent with the mileage, and the RS bodykit should be original or documented.

Verify the VIN, trim, seats, wheels, brakes and badges against the claimed specification. The RS500 is a separate limited derivative and should not be used to inflate the value of a standard Mk2 RS. Ask for the history file, older MOTs, invoices and proof of any engine or suspension work. Use the DVSA recall service to check outstanding actions, then confirm Ford or specialist records where possible. The right car should have a documented plenum history or no evidence of concern, a strong turbo engine file, healthy differential and gearbox, correct wheels and tyres, and a body that matches its story. This guide combines Ford technical material, PistonHeads ownership evidence and DVSA recall data. It assigns no exact production count to the derivative.
