2017 Ford Focus Rs 0-60 – Master The Launch And Real-World Performance
The 2017 Ford Focus RS is a high-performance hatchback designed to deliver blistering acceleration and rally-inspired handling through its advanced all-wheel-drive system. Achieving the factory-claimed 0-60 mph time requires a perfect combination of tire temperature, surface grip, and the correct execution of the built-in launch control system. This guide explores the mechanical nuances and driving techniques needed to extract maximum performance from this modern legend.
You probably remember the first time you saw the “RS” badge on a modern Ford; it promised a level of performance that could embarrass dedicated sports cars. To achieve the 2017 ford focus rs 0-60 factory rating of 4.7 seconds, you need more than just a heavy right foot.
In this article, we will break down the technology that makes these quick sprints possible and the real-world factors that might be holding your car back. We will also cover essential maintenance and safety checks to ensure your RS stays as fast as the day it left the showroom.
Whether you are a seasoned track day regular or a weekend DIYer looking to optimize your ride, understanding the mechanics of a perfect launch is the first step. Let’s dive into the details of the 2.3L EcoBoost powerhouse and the GKN Twinster system that puts that power to the pavement.
Understanding the 2017 ford focus rs 0-60 Benchmarks
When Ford released the Focus RS in the United States, the headline figure was a 0-60 mph sprint in just 4.7 seconds. This put it directly in competition with the Volkswagen Golf R and the Subaru WRX STI, often outperforming them in raw acceleration tests.
However, achieving this number in the real world is often different than a controlled manufacturer test on a prepped surface. Most owners find that their real-world times hover between 4.8 and 5.2 seconds depending on several environmental factors.
The 2017 ford focus rs 0-60 time is heavily dependent on the 2.3L EcoBoost engine’s ability to “overboost.” This feature allows the turbocharger to provide extra torque for short bursts, which is critical during the initial launch phase.
The Impact of Elevation and Air Density
Turbocharged engines are sensitive to “density altitude,” which refers to how “thick” the air is based on temperature and pressure. If you are testing your car in a high-elevation area like Denver, your times will naturally be slower than at sea level.
Cool, crisp air contains more oxygen, allowing the ECU (Engine Control Unit) to inject more fuel and create a more powerful explosion in the cylinders. On a hot summer day, the intercooler may struggle to shed heat, leading to “heat soak” and reduced timing.
Surface Conditions and Grip
Even with an advanced all-wheel-drive (AWD) system, the surface you are driving on matters immensely. Asphalt provides different friction coefficients than concrete, and a dusty road will cause the traction control to intervene, killing your momentum.
Professional testers often use a “1-foot rollout,” which mimics the way drag strips measure time. If you are using a GPS-based timer like a Dragy or a VBox, ensure you know if the rollout is enabled to compare your times fairly.
How to Use Launch Control for the Best Results
Ford equipped the RS with a dedicated launch control system to help drivers achieve consistent results without destroying the clutch. This system manages engine RPM and boost pressure while you focus on the physical release of the clutch pedal.
To engage launch control, use the steering wheel buttons to navigate to the “Driver Assist” menu on the instrument cluster. Select “Launch Control” and ensure the box is checked, then follow the prompts on the screen.
Once active, depress the clutch fully and shift into first gear. Mash the accelerator to the floor; the engine will bounce off a specific RPM limit (usually around 5,000 RPM) while building boost pressure in the manifold.
The Art of the Clutch Release
Do not simply “dump” the clutch by sliding your foot off the side of the pedal. Instead, perform a rapid but controlled “slip” to allow the AWD system to bite without shocking the drivetrain too violently.
A violent clutch dump can cause the car to bog or, worse, cause mechanical failure in the Rear Drive Unit (RDU). Practice finding the “bite point” where the car begins to move before fully committing to the release.
Monitoring Drivetrain Temperatures
The Focus RS is notorious for its RDU getting hot during repeated hard launches or track sessions. If the system detects too much heat, it will temporarily disable the AWD system to protect the clutches, turning your car into a front-wheel-drive hatchback.
Always allow for a “cool-down” lap or a few minutes of steady driving between 0-60 attempts. This allows air to flow over the RDU housing and keeps the fluid temperatures within a safe operating range.
Factors That Influence Your 2017 ford focus rs 0-60 Performance
Several mechanical and environmental variables can shave tenths of a second off your time or add them on. Understanding these factors allows you to prepare your car for the best possible performance run.
When testing your 2017 ford focus rs 0-60 times, remember that the car’s weight plays a massive role. A full tank of fuel and a passenger can add 200-300 pounds, which significantly impacts the power-to-weight ratio.
Tire pressure is another critical variable that many DIYers overlook. While the door placard might suggest 46 PSI for high-speed stability, dropping the pressure slightly can increase the “contact patch” and improve off-the-line traction.
Tire Compounds: Cup 2 vs. Super Sport
The 2017 Focus RS came with two main tire options: the Michelin Pilot Super Sport and the track-focused Michelin Pilot Sport Cup 2. The Cup 2 tires are essentially “street-legal slicks” that require significant heat to work correctly.
If your car is equipped with Cup 2s, your 0-60 times will be poor until the rubber is warm to the touch. In cold or wet conditions, the Pilot Super Sport is actually the superior tire for daily driving and quick sprints.
Fuel Quality and Octane Rating
The 2.3L EcoBoost engine uses a high compression ratio and significant boost pressure. To reach the advertised 350 horsepower and 350 lb-ft of torque, you must use 93-octane premium fuel.
Using lower-grade fuel will cause the knock sensors to pull ignition timing, which protects the engine but drastically reduces power output. For the best performance, find a high-quality “Top Tier” fuel station and avoid “winter blend” fuels if possible.
The Role of the GKN Twinster All-Wheel-Drive System
The magic of the Focus RS lies in its GKN Twinster AWD system. Unlike traditional systems that use a center differential, the RS uses a Rear Drive Unit with two electronically controlled clutch packs.
These clutches can send up to 70% of the engine’s torque to the rear axle. From there, 100% of that available rear torque can be sent to either the left or right wheel, creating a “torque vectoring” effect that pushes the car out of corners.
During a 0-60 run, the RDU locks both rear clutches to ensure maximum traction from all four wheels. This prevents the front wheels from spinning uselessly and translates every bit of engine power into forward motion.
Drift Mode vs. Track Mode
While “Drift Mode” is the most famous setting, it is not the fastest for a straight-line sprint. Drift Mode softens the dampers and changes the torque distribution to encourage the rear end to slide out.
For the best 0-60 results, use “Track Mode” or “Normal Mode” with Launch Control. Track Mode stiffens the suspension by 40%, which reduces “squat” during the launch and keeps the tires flatter against the pavement for better grip.
Maintenance of the AWD System
The RDU and the Power Transfer Unit (PTU) contain specialized fluids that break down over time, especially with hard use. If you plan on performing frequent launches, consider changing these fluids every 15,000 to 20,000 miles.
Check for leaks around the RDU seals regularly. A small leak can lead to low fluid levels, which causes the clutches to slip or overheat prematurely, ruining your performance and potentially leading to a costly repair.
Maintenance Tips to Keep Your RS Quick
A fast car is a healthy car. If your maintenance is lagging, your performance will suffer. The 2017 Focus RS is a precision machine that requires specific care to maintain its competitive edge.
One of the most important things for an RS owner is the Head Gasket Recall. Early 2017 models were sometimes fitted with the wrong head gasket (intended for the Mustang EcoBoost), which led to coolant consumption and engine failure.
Ensure your car has had the “17B32” service action performed by a Ford dealer. A healthy engine with proper compression is the foundation of a quick 0-60 time; a leaking head gasket will cause misfires and power loss long before the engine fails completely.
Spark Plug Gapping and Ignition
Under high boost, the “spark blow-out” phenomenon can occur if your spark plug gap is too wide. This results in a stumble or hesitation when you are at wide-open throttle (WOT).
Expert mechanics often recommend gapping the spark plugs to a tighter specification (around 0.026 to 0.028 inches) for modified or heavily driven cars. Always use the factory-recommended Motorcraft or high-quality iridium plugs.
Oil Quality and Viscosity
The Focus RS requires 5W-50 full synthetic oil. This high viscosity is necessary to protect the engine bearings under the extreme heat and pressure generated by the turbocharger during hard acceleration.
Never substitute a lower viscosity oil like 5W-30 just because it is cheaper or more available. The 5W-50 oil provides the necessary “film strength” to prevent metal-on-metal contact when the engine is under maximum load.
Modifying Your Focus RS for Sub-4 Second Runs
If the factory performance isn’t enough, the aftermarket for the Focus RS is massive. With a few targeted upgrades, it is possible to drop your 0-60 times into the high 3-second range.
The first modification most owners choose is a high-flow air filter and an upgraded intercooler. The factory intercooler is known to be a “weak link,” often struggling to keep intake air temperatures (IATs) low during repeated pulls.
By installing a larger intercooler, you provide the engine with cooler, denser air, allowing the ECU to maintain maximum boost and timing for longer periods. This is especially helpful during the second half of a 0-60 sprint.
The Power of a Custom Tune
Using a handheld programmer like the Cobb Accessport allows you to flash a new map to the ECU. These tunes optimize the air-fuel ratio, increase boost pressure, and can even refine the launch control parameters.
A “Stage 1” tune typically adds 20-30 horsepower and a significant amount of mid-range torque. This extra “grunt” makes the car feel much more aggressive and can shave several tenths of a second off your 0-60 time.
Weight Reduction Strategies
You don’t always need more power to go faster; sometimes you just need less weight. Lightweight forged wheels can reduce “unsprung mass,” which makes it easier for the engine to spin the tires and for the suspension to react to bumps.
Removing the rear seats or switching to a lightweight lithium-ion battery are common “free” or low-cost ways to improve the power-to-weight ratio. Just remember that every pound removed is a step away from daily-driver comfort.
Frequently Asked Questions About 2017 ford focus rs 0-60
Is the 2017 Ford Focus RS 0-60 time faster than the Golf R?
In most independent testing, the Focus RS and the VW Golf R are very close. While the RS has more raw power, the Golf R’s dual-clutch transmission (DSG) allows for faster shifts, often resulting in nearly identical 0-60 times in real-world conditions.
Does using Launch Control damage the car?
Launch Control is designed to be used, but it does put significant stress on the clutch, axles, and RDU. Using it occasionally is fine, but back-to-back launches without cooling periods will lead to accelerated wear and potential component failure.
Can I get a better 0-60 time by shifting manually?
The Focus RS only comes with a 6-speed manual transmission. To get the best 0-60 time, you must be proficient at “flat-foot shifting” (if your tune supports it) or extremely fast traditional shifts to ensure the turbo doesn’t lose boost between gears.
Why is my Focus RS 0-60 time slower than 5 seconds?
The most common reasons for slower times include poor fuel quality, worn tires, high ambient temperatures, or high elevation. Additionally, if the RDU is too hot, the car may be limiting power to the rear wheels, reducing your initial “dig” off the line.
Final Thoughts on Mastering the RS Launch
The 2017 Focus RS remains one of the most exciting performance cars of the last decade. Achieving the perfect 2017 ford focus rs 0-60 run is a rewarding experience that requires a deep understanding of your vehicle’s mechanical limits and the environment around you.
Remember to prioritize safety above all else. Only perform high-speed testing on closed courses or drag strips where the surface is prepared and help is nearby if something goes wrong. Always check your tire pressures and fluid levels before a day of performance driving.
By following the maintenance tips and launch techniques outlined in this guide, you can ensure your RS remains a formidable competitor on the road and the track. Stay safe, keep an eye on those gauges, and enjoy the incredible engineering that Ford Performance put into this machine!
