Understanding the ford focus st specs 2013 Engine and Drivetrain
The centerpiece of the 2013 Focus ST is its 2.0-liter turbocharged EcoBoost inline-four engine. This powerplant was designed to provide a broad torque curve, making the car feel responsive in almost any gear. It utilizes high-pressure direct injection and twin independent variable camshaft timing (Ti-VCT) to optimize efficiency and power.
Stock performance figures are impressive for its class, delivering 252 horsepower at 5,500 RPM and 270 lb-ft of torque at 2,500 RPM. This power is routed exclusively through a Getrag-Ford MMT6 six-speed manual transmission. No automatic option was offered, highlighting Ford’s commitment to the enthusiast market for this specific model year.
Turbocharger and Induction System
The engine uses a BorgWarner K03 low-inertia integrated turbocharger system. This setup minimizes turbo lag, allowing the engine to reach peak torque very early in the rev range. An overboost feature allows the engine to increase torque for up to 15 seconds, providing an extra kick during overtaking maneuvers.
Air is cooled via a front-mounted intercooler (FMIC) before entering the intake manifold. While the stock intercooler is sufficient for daily driving, many DIYers find it is the first bottleneck when increasing power. If you live in a warm climate, heat soak can become a noticeable issue during aggressive driving sessions.
The MMT6 Manual Transmission
The six-speed manual gearbox features triple-synchros on the first four gears to ensure smooth shifting. The gear ratios are tightly spaced to keep the engine within its power band. Power is delivered to the front wheels through an open differential, which is managed by an electronic system.
Ford utilized a Torque Vectoring Control system rather than a traditional mechanical limited-slip differential. This system applies slight braking force to the inner front wheel during cornering. This helps pull the car into the apex and reduces the understeer typically associated with high-horsepower front-wheel-drive cars.
Chassis, Suspension, and Braking Systems
The 2013 Focus ST sits 10mm lower than the standard Focus, giving it a more aggressive stance and a lower center of gravity. The suspension was completely reworked by Ford’s Team RS to handle the increased power and provide sharper turn-in. It uses a MacPherson strut front setup and a multi-link “Control Blade” rear suspension.
One unique aspect of the ford focus st specs 2013 is the variable-ratio steering rack. This rack becomes more sensitive as you turn the wheel further from the center. This allows for stable high-speed cruising on the highway while providing lightning-fast responses on tight, technical backroads or autocross courses.
Springs, Dampers, and Anti-Roll Bars
The ST features uprated springs and dampers that are significantly stiffer than those found on the Titanium or SE trims. The rear suspension includes a unique anti-roll bar designed to allow for “lift-off oversteer.” This allows experienced drivers to rotate the car using the throttle and brakes, making it feel much more alive than a standard commuter car.
For DIY mechanics, replacing these components is straightforward, though the rear springs require a specialized compressor or careful lowering of the rear subframe. Always inspect the bushings for signs of cracking, as the increased stiffness of the ST suspension puts more load on rubber components over time.
Braking Performance and Wheel Specs
Stopping power is provided by 12.6-inch vented front rotors and 10.7-inch solid rear rotors. The calipers are single-piston units, but they are tuned for high initial bite. The 2013 model came standard with 18×8-inch “Rado Gray” or “Flash Gray” alloy wheels wrapped in 235/40R18 Goodyear Eagle F1 Asymmetric 2 summer tires.
If you are planning to track your car, consider upgrading to a high-temperature brake fluid like Motul RBF600. The stock pads are excellent for the street but can fade under heavy track use. Always check your brake lines for any signs of swelling or leaks during your routine oil changes.
Essential DIY Maintenance and Fluid Capacities
Maintaining the ford focus st specs 2013 requires attention to detail, especially regarding fluid types and intervals. Because this is a direct-injected, turbocharged engine, it is susceptible to carbon buildup on the intake valves. Using high-quality synthetic oil and following a strict maintenance schedule is non-negotiable for long-term reliability.
The oil capacity for the 2.0L EcoBoost is 5.7 quarts (5.4 liters). Ford recommends using 5W-30 synthetic blend or full synthetic oil that meets the WSS-M2C946-A specification. Many enthusiasts prefer a high-quality full synthetic to better protect the turbocharger bearings from heat-related shearing.
Fluid Types and Torque Specifications
- Engine Oil: 5.7 Quarts 5W-30 Full Synthetic.
- Transmission Fluid: 1.7 Quarts Dual Clutch Transmission Fluid (XT-11-QDC).
- Coolant: Motorcraft Orange Antifreeze/Coolant (50/50 mix).
- Brake Fluid: DOT 4 LV (Low Viscosity) High Performance.
- Wheel Lug Nuts: 100 lb-ft (135 Nm).
- Spark Plug Gap: 0.028 to 0.030 inches (0.7mm to 0.75mm).
Changing the transmission fluid is a common DIY task that significantly improves shift feel. Use a long funnel to reach the fill plug located on the front of the gearbox. Ensure the car is level when checking the fluid height to get an accurate reading.
Spark Plugs and Ignition System
The EcoBoost engine is sensitive to spark plug condition. If you experience a stutter under heavy acceleration, it is likely time for new plugs. Many owners choose to “step down” one heat range colder (such as NGK LTR7IX-11) if they have installed a performance tune.
Always use a torque wrench when installing spark plugs to avoid stripping the threads in the aluminum cylinder head. The recommended torque for spark plugs in this engine is 12 lb-ft. Over-tightening can lead to cracked ceramic insulators, causing a misfire that is difficult to diagnose.
Common Problems and Troubleshooting for the 2013 Model
Every vehicle has its quirks, and the 2013 Focus ST is no exception. Being the first year of the ST in the United States, there were a few “teething” issues that owners should be aware of. Identifying these early can save you thousands of dollars in professional repair costs.
One of the most documented issues is the wiring harness rub. The engine wiring harness can rub against the sharp edges of the engine block or battery tray. This leads to intermittent electrical shorts, causing the car to enter “limp mode” or display various sensor errors. Inspect the harness near the airbox and wrap any exposed areas with high-heat electrical tape.
Low-Speed Pre-Ignition (LSPI)
LSPI is a phenomenon where the air-fuel mixture ignites before the spark plug fires, usually under high load and low RPM. This can cause catastrophic engine failure, such as cracked pistons. To avoid this, never “lug” the engine; avoid flooring the accelerator if you are in 5th or 6th gear at low speeds.
Downshift to a lower gear to get the RPMs up before requesting full boost. Using a high-quality oil specifically formulated to combat LSPI (look for API SN Plus or SP ratings) is also a critical preventative measure. This is one of the most important safety tips for any modern turbocharged engine owner.
Rear Motor Mount (RMM) Weakness
The stock rear motor mount on the 2013 model is notoriously soft. Under hard acceleration, the engine can pitch back and forth, causing a loud “bang” against the firewall. This is often referred to as the “1-2 bang” by the community. Replacing the stock mount with an aftermarket polyurethane unit or the updated Ford Focus Electric mount is a highly recommended DIY upgrade.
This modification improves traction and shift feel by reducing engine movement. However, be aware that stiffer mounts will increase NVH (Noise, Vibration, and Harshness) inside the cabin. Most enthusiasts find the trade-off worth the improved performance and durability.
Interior Specs and Daily Usability
The 2013 Focus ST wasn’t just built for the track; it was designed to be a functional daily driver. The interior features a unique set of gauges on top of the dashboard, showing oil temperature, oil pressure, and boost pressure. This allows you to monitor engine health in real-time without needing an external scan tool.
The ST came in three trim levels: ST1, ST2, and ST3. The ST1 features basic cloth seats, while the ST2 adds Recaro partial-leather seats and the MyFord Touch infotainment system. The ST3 is the top-tier trim, offering full leather heated Recaro seats, HID headlamps, and ambient interior lighting.
Cargo Space and Practicality
Despite its performance credentials, the ST retains the standard Focus hatchback’s utility. You get 23.8 cubic feet of cargo space behind the rear seats. Folding the seats down expands this to 44.8 cubic feet, which is plenty of room for a set of track tires or camping gear for a weekend getaway.
The seating position in the Recaro buckets is quite aggressive. While they provide excellent lateral support during high-G cornering, some drivers find them a bit tight for long-distance road trips. If you are shopping for a used ST, sit in both the ST1 and ST2/3 seats to see which fits your body type better.
Technology and Connectivity
The 2013 model year utilized the SYNC system, which allows for Bluetooth hands-free calling and audio streaming. While the early MyFord Touch systems were criticized for being slow, many have been updated via software to improve responsiveness. For DIYers, it is possible to swap the older screen for the newer SYNC 3 system found in later models, providing Apple CarPlay and Android Auto compatibility.
Always check the fuse box located behind the glovebox if your infotainment system or USB ports stop working. Blown fuses are a common culprit for minor electrical gremlins in the cabin. Keeping a spare set of mini-fuses in the car is a smart move for any owner.
Performance Potential: Beyond the Stock Specs
The ford focus st specs 2013 provide a solid foundation, but the aftermarket for this car is massive. Because the engine is shared with several other Ford models, parts are plentiful and relatively affordable. A few simple modifications can significantly change the character of the vehicle.
A “Stage 1” upgrade usually consists of a high-flow air filter and a software recalibration (tune). This can easily bump the output to around 275 horsepower and over 300 lb-ft of torque. However, keep in mind that increasing boost also increases heat, making an intercooler upgrade almost mandatory for consistent performance.
Exhaust and Intake Upgrades
The stock exhaust is quite muffled, featuring a “Sound Symposer” that pipes artificial engine noise into the cabin. Many owners choose to delete the symposer and install a 3-inch cat-back exhaust system. This provides a genuine turbocharged growl and reduces backpressure, allowing the turbo to spool slightly faster.
Intake upgrades primarily provide more “induction noise,” letting you hear the bypass valve and turbocharger whistle. While they don’t add massive horsepower on their own, they enhance the driving experience. Be sure to use a cleaning kit for your reusable filters every 10,000 miles to maintain optimal airflow.
Suspension and Braking Mods
For those looking to improve handling further, lowering springs or coilovers are popular choices. These reduce body roll and improve the car’s aesthetic. If you plan on autocrossing, adding a larger rear anti-roll bar can help the car rotate even more effectively through tight corners.
Upgrading to stainless steel braided brake lines will improve pedal feel by eliminating the “sponginess” of factory rubber lines. When combined with high-performance brake pads, the ST becomes a formidable opponent on a technical circuit. Always perform a brake bleed after changing lines to ensure no air is trapped in the ABS module.
