Performance: Ford Focus RS vs Subaru WRX STI

Performance is the heart and soul of the Ford Focus RS and the Subaru WRX STI. Each offers a unique approach to delivering thrilling driving dynamics, making them favourites among motoring enthusiasts.
Engine and Power
The Ford Focus RS is powered by a 2.3-litre turbocharged EcoBoost engine that delivers 350 horsepower and 440 Nm of torque. This engine is shared with the Ford Mustang EcoBoost, but the Focus RS takes it to the next level with its advanced cooling systems and power delivery. The result is a car that feels alive with every throttle input, offering a relentless power surge.
The Subaru WRX STI, by contrast, uses a 2.5-litre turbocharged flat-four “Boxer” engine. This engine layout lowers the vehicle’s centre of gravity, enhancing stability during high-speed cornering. With 310 horsepower and 393 Nm of torque, the WRX STI is slightly less powerful on paper but compensates with an impressive power band and linear throttle response.
Acceleration
The Focus RS accelerates from 0 to 60 mph in a blistering 4.7 seconds. This feat is aided by its quick-shifting six-speed manual gearbox and precise power delivery. The car launches with authority, especially when using its launch control feature, optimising traction for rapid take-offs.
The WRX STI is neither slouch nor slow, with a 0-60 mph time of 5.1 seconds. Its symmetrical all-wheel-drive system and low-end solid torque make it quick off the line, and its performance feels consistent across various driving conditions, whether on dry tarmac or slippery gravel roads.
Driving Dynamics
The Focus RS offers an engaging and dynamic driving experience. Its clever all-wheel-drive system sends power to individual wheels, significantly improving cornering performance. The Drift Mode adds an extra layer of fun, allowing drivers to slide the car in controlled conditions. However, its stiff suspension setup can feel harsh over rough surfaces, making it more suited to spirited drives than relaxed cruising.
The WRX STI channels its rally heritage into its driving dynamics. While it doesn’t offer playful features like Drift Mode, it excels in precise handling and composure. The hydraulic steering provides excellent feedback, and its balanced weight distribution ensures confidence-inspiring stability. Its suspension is slightly more forgiving than the RS, making it a better option for uneven roads or longer journeys.
Design

Both vehicles are designed to stand out, but their styling approaches reflect different philosophies. The Focus RS opts for a contemporary, aggressive look, while the WRX STI leans into its rally-inspired heritage.
Exterior Styling
The Ford Focus RS is bold and modern. Its wide stance, aggressive front bumper, and prominent rear spoiler emphasise its performance credentials. Details like the 19-inch alloy wheels and sporty RS badging complete the look, making it clear that this is no ordinary hatchback.
In contrast, the Subaru WRX STI stays true to its rally roots. The functional hood scoop, which feeds air to the intercooler, is a standout feature, as is its towering rear wing, which improves aerodynamics. While some might find its design slightly dated, fans of classic Subaru styling will appreciate its authenticity and rugged appeal.
Interior Quality
Inside, the Ford Focus RS blends sporty elements with everyday practicality. The Recaro seats provide excellent support during aggressive driving while maintaining reasonable comfort for daily use. The flat-bottom steering wheel adds to the sporty vibe, though the interior materials, such as hard plastics, may feel underwhelming to some.
The WRX STI’s interior mirrors its rally-car focus with a functional and driver-centric layout. The leather and Alcantara-trimmed seats are supportive, and the red stitching adds a sporty touch. However, like the Focus RS, the cabin prioritises function over luxury, which may disappoint those seeking a more premium feel.
Technology and Features
In today’s market, technology plays a significant role in enhancing the driving experience. Both cars offer competitive infotainment systems and essential features, though neither focuses heavily on advanced driver-assistance technologies.
Infotainment
The Ford Focus RS is equipped with the SYNC 3 infotainment system, which is among the most intuitive in its class. The 8-inch touchscreen is responsive, and features like Apple CarPlay, Android Auto, and voice commands ensure seamless connectivity. The system also integrates with performance apps, allowing drivers to monitor key metrics like G-forces and lap times.
While functional, Subaru’s STARLINK infotainment system lags behind SYNC 3 regarding interface design and ease of use. The system includes similar features like Apple CarPlay and Android Auto, but navigating the menus can feel less intuitive. However, it gets the job done and supports most modern connectivity needs.
Driver Assistance
The Focus RS offers basic driver-assistance features like rear parking sensors and a reversing camera. These features are helpful for urban manoeuvring but are limited compared to modern cars.
The WRX STI includes optional driver-assistance systems like blind-spot monitoring and rear cross-traffic alert. While these are welcome additions, both cars focus more on delivering raw driving thrills than on packing in the latest tech.
Practicality
Performance doesn’t have to come at the expense of practicality, and both the Focus RS and WRX STI manage to balance usability with excitement.
Space and Comfort
The Ford Focus RS, as a hatchback, offers a versatile cargo area with 260 litres of boot space, expandable by folding the rear seats. This makes it ideal for carrying more oversized items like luggage or sports equipment. The cabin provides sufficient headroom and legroom for front passengers, though rear-seat space may feel tight for taller occupants.
The WRX STI, a sedan, offers a slightly larger boot with 340 litres of space. Its rear seats also fold down, adding some flexibility. However, the sloping roofline and smaller rear doors can make accessing the back seats more challenging.
Daily Usability
Both vehicles are relatively practical for daily use, though their sporty suspension setups are less comfortable than non-performance-oriented models. The Focus RS’s hatchback design gives it an edge for city errands, while the WRX STI’s smoother ride makes it better suited for long-distance travel.
Fuel Economy and Running Costs
Performance cars often come with higher running costs, and the Focus RS and WRX STI are no exceptions. However, there are notable differences in their efficiency and maintenance requirements.
Fuel Efficiency
The Focus RS offers a combined fuel economy of approximately 28 mpg, which is commendable for a car of its performance calibre. Its smaller engine and advanced EcoBoost technology help keep fuel consumption in check during everyday driving.
With its larger Boxer engine, the WRX STI achieves a lower combined fuel economy of around 23 mpg. Its thirstier nature is a trade-off for its rally-inspired performance, making it less economical than the RS.
Maintenance and Reliability
Subaru’s reputation for reliability gives the WRX STI a decisive edge regarding long-term ownership. Its robust engineering and durable components are well-suited to withstand aggressive driving. However, regular maintenance, such as timing belt replacements, can be costly.
While reliable overall, the Focus RS has faced some issues with earlier models, particularly with head gasket failures. Prospective buyers should ensure these issues have been addressed when purchasing a used unit. Regular servicing is essential for both cars to maintain their performance and longevity.
Ownership Experience
Owning a high-performance car is as much about the experience as the vehicle itself. From community support to aftermarket options, the Focus RS and WRX STI offer plenty for enthusiasts.
Cost
Both cars are similarly priced in the used market, typically between £25,000 and £35,000, depending on mileage and condition. Running costs, including fuel, insurance, and maintenance, are higher, but enthusiasts are often willing to pay the premium for their capabilities.
Community and Aftermarket
The Ford Focus RS benefits from a vibrant, enthusiastic community and numerous aftermarket options, from performance upgrades to aesthetic customisations. Owners can easily connect with others at events or online forums, sharing tips and experiences.
The WRX STI has an equally passionate following and a heritage rooted in motorsport. Aftermarket parts are available, allowing owners to enhance performance, handling, or styling to suit their preferences. Its rally pedigree makes it a favourite among tuners and rally enthusiasts alike.
