The Ford Focus ST is powered by a 2.0-liter EcoBoost engine, and its horsepower varies by market and model year. In stock form it sits around 250–252 hp, with torque typically near 360 Nm. With common bolt-ons and a tune, many owners see 300–350 hp, and more extensive builds—with upgraded turbo, internals, and fueling—can push beyond 400 hp. Availability and exact figures depend on the region and generation, and Ford has largely shifted Focus ST sales toward used-market ownership in recent years.
Stock horsepower: baseline numbers by market
Below is a snapshot of typical factory outputs for the Focus ST across markets. Exact figures can vary by year, emissions equipment, and fuel quality.
- Europe/Global markets (Mk3, 2013–2018): 250 PS (about 246–252 hp) with around 360 Nm of torque.
- United States (Mk3, 2013–2018): roughly 252 hp with about 365 Nm (270 lb-ft) of torque.
Note: These baselines reflect stock configurations. For some markets, minor adjustments can exist due to compliance and spec differences. As a result, the practical takeaway is that the Focus ST starts in the mid-240s to the mid-250s horsepower range, with torque in the mid- to upper-360 Nm range depending on market.
How much horsepower can you add? tuning and upgrade paths
Before listing upgrade paths, it’s useful to understand that gains depend on the starting baseline, fueling, heat management, and the strength of the drivetrain. The following are common routes enthusiasts use to increase horsepower on the Focus ST.
- Stage 1 — ECU remap with supporting bolt-ons (intake, exhaust, intercooler upgrades): typically adds ~40–90 hp, bringing the car into the 290–340 hp range (crank).
- Stage 2 — more comprehensive intake/exhaust changes plus intercooler, downpipe, and fueling upgrades (e.g., injectors, high-flow pump): commonly adds ~80–150 hp, targeting roughly 340–410 hp (crank).
- Stage 3+ — substantial turbo and internal changes (larger turbo, forged internals, upgraded clutch/transmission components, enhanced cooling): potential gains of 200+ hp beyond stock, with total outputs around 450–550+ hp depending on hardware and tuning.
- Important notes — power delivery and reliability: Real-world results depend on fuel quality (high-octane fuels help), heat management (engine and intercooler), and supporting modifications (clutch, transmission, differential). Large power increases also raise maintenance costs and may affect warranties where applicable.
Concluding this section, a Focus ST can be transformed from a sub-300 hp daily driver into a wide range of high-performance setups. Most street-focused builds stay in the 300–400 hp band with careful tuning and reliable components; ambitious builds can exceed 450 hp with substantial investments in turbo, internals, and cooling.
Practical considerations for power upgrades
Before diving into upgrades, consider the intended use and maintenance requirements. Higher horsepower demands better cooling, a robust fueling system, and a drivetrain capable of handling the extra load. Fuel quality and octane rating become more critical at elevated power levels. Warranty coverage may be affected, and emissions compliance can vary by jurisdiction. For a daily driver, many enthusiasts favor Stage 1–Stage 2 setups that balance performance with reliability and usability; for track-focused builds, Stage 3+ configurations are more common but require meticulous engineering and professional installation.
Summary
The Ford Focus ST starts with roughly 250–252 horsepower in most markets, offering a solid foundation for more horsepower through tuning and upgrades. Stage 1 and Stage 2 bolt-ons can push power into the 300–410 hp range, while Stage 3+ builds with bigger turbos and strengthened internals can surpass 450 hp. Real-world results depend on market, model year, fueling, cooling, and the quality of the build. For anyone chasing substantial horsepower, a well-planned strategy that includes cooling upgrades, fueling, and transmission/drive-train reinforcement is essential for both performance and reliability.
Is a golf R faster than a Focus ST?
The Golf GTI goes toe-to-toe with the Focus ST, offering similar front-wheel-drive thrills and acceleration, but outright bragging rights belong to the 320hp Golf R which, with four-wheel drive, blasts from 0-62mph in a sports-car-baiting 4.7 seconds.
