Ford Fiesta ST Mk8 Buying Guide
Fiesta ST Mk8 Buying Guide
The Ford Fiesta ST Mk8, introduced in 2018, is a popular hot hatch that combines excellent performance, a comfortable ride, and modern features. If you’re thinking of buying a used Fiesta ST Mk8, or are looking at a new one, it’s important to know what to look out for. In this buying guide, we’ll cover the key options, trim levels, and considerations for both the standard Mk8 and the later Mk8.5 facelift model.
1. Trim Levels and Options
The Fiesta ST Mk8 is available in a few different trims, each offering a slightly different set of features. Here’s an overview of the most common trims available:
ST Line and ST Line X
While not technically the full performance ST model, the ST Line and ST Line X trims are worth mentioning as they offer sporty styling cues but with a less powerful engine. These trims come with sporty body kits, upgraded wheels, and a lowered suspension, but they don't have the performance upgrades of the ST. If you’re after the genuine performance experience, it’s important to stick to the proper Fiesta ST.
Fiesta ST (Standard Model)
The standard Fiesta ST is the main performance variant and features a 1.5-litre EcoBoost engine producing 200 horsepower. This trim comes with sportier suspension, optional limited-slip differential (LSD), and driving modes that adjust the car’s performance characteristics. The interior includes sporty Recaro seats, a sporty steering wheel, and an upgraded infotainment system with SYNC 3.
ST-2
The ST-2 is the mid-level trim of the Fiesta ST Mk8, and it’s the most popular choice for many buyers. It offers a solid balance of performance and features, with additional upgrades such as a larger touchscreen, a rear-view camera, and keyless entry. It also comes with more comfort and tech features than the base model, making it a good choice for those who want a sportier experience without sacrificing too much practicality.
ST-3
The ST-3 is the top-spec trim, offering the most luxurious options. Standard features include the upgraded 8-inch touchscreen, full leather upholstery, and more advanced driver assistance systems, such as parking sensors and adaptive cruise control. The ST-3 is ideal for those who want all the performance of the Fiesta ST, but with added comfort and convenience.
Performance Packs are a must! Performance packs include the limited-slip differential, launch control and the shift-light. If you have purchased a Fiesta ST without the performance pack, you can purchase the Quaife Limited-Slip Differential separately here. The shift light and launch control can be activated via Forscan (full license needed).
2. Mk8.5 Facelift
In 2021, Ford launched the Mk8.5 facelift version of the Fiesta ST, which brought several updates to the model. While the core performance characteristics remained the same, the facelift introduced some changes worth noting:
Exterior Changes
The Mk8.5 facelift features updated front and rear styling. The front grille is larger, with sharper lines, and the overall appearance is more aggressive. The rear end also sees slight revisions to the design, including revised rear lights and a more modern look. These changes give the Mk8.5 a fresher and more dynamic appearance.
Interior and Tech Updates
Inside, the Mk8.5 introduced some improvements to the infotainment system, with the addition of the larger 8-inch touchscreen and better smartphone integration, including wireless Apple CarPlay and Android Auto. The interior also feels slightly more refined, with better materials and improved ergonomics.
Performance and Driving
The facelifted model retained the same 1.5-litre EcoBoost engine as the pre-facelift version, meaning no change in horsepower or performance. However, there were some improvements to suspension tuning, which Ford claims offer better ride comfort and sharper handling. Some buyers may notice a slightly more refined driving experience, especially on long journeys or rough roads.
Driver Assistance Features
Another key upgrade in the Mk8.5 is the introduction of additional driver assistance systems, such as lane-keeping assist and improved adaptive cruise control, which are now standard on higher trims like the ST-3.
3. What to Look for When Buying a Used Fiesta ST Mk8
When considering a used Fiesta ST Mk8, there are a few important things to keep in mind:
Condition and Service History
As with any used car, always check the condition of the car and ask for a full service history. A well-maintained Fiesta ST will have had regular oil changes, brake checks, and attention to any recalls or technical service bulletins. Ensure the car has been serviced at regular intervals, especially for things like the suspension and brakes, which take a bit more wear due to the car's sporty nature.
Suspension and Ride Comfort
The Fiesta ST is known for its firm ride, particularly in the ST-2 and ST-3 trims, but suspension wear can still become an issue in higher-mileage models. Pay attention to how the car handles on your test drive. If the ride feels bouncy or there are any unusual noises from the suspension, it could indicate wear or issues with the dampers or springs.
Engine and Gearbox
The 1.5-litre EcoBoost engine in the Fiesta ST Mk8 is generally reliable, but it’s important to ensure there are no signs of turbo issues, rough idling, or poor performance. A well-maintained engine should run smoothly and provide plenty of power throughout the rev range. Make sure the gearbox shifts cleanly without any hesitation or grinding.
Brake Wear
Performance cars like the Fiesta ST often see more wear on the brakes, so check the condition of the brake pads and discs. Worn-out brakes should be replaced before they cause further damage, so if the car you’re considering has high mileage, it may be worth checking whether the brakes have been replaced recently.
Recalls
Be sure to check if the car has any outstanding recalls. Ford typically addresses recalls quickly, but it’s always worth confirming that any necessary work has been completed before purchasing.
5. Mk8 ST Common Problems
The Fiesta ST Mk8 is largely trouble free which is refreshing to hear as a new/prospective owner. There are however some points to note:
Steering Rack: A number of owners have experienced a "knock" when turning left to right, or right to left, this is well documented online, and known by Ford. There is no suitable solution to this, however if you are experiencing the knock, take your vehicle back to your local Ford service partner for inspection.
Fuel Pump: The fuel pump, more specifically the high-pressure fuel pump located in the engine bay, can have supply issues when vehicles are tuned. Between 2000-3000rpm you may feel the car "pull back" slightly. This feeling could be the fuel pump struggling to supply the required amount of fuel. Some people have reported that fitting the Mk2 Puma ST fuel pump has cured the problem however this is incorrect as the fuel pumps are identical.
Chassis: As we have seen with the Mk7 ST180 - it is likely for the Mk8 ST to suffer some bush degradation over its lifespan. Particular areas to note are the rear chassis beam bushes, the upper isolators (perched atop the coil spring at the rear), and front-lower control arms.
Engine Mount: Some owners have reported failures of their lower torque mount (lower engine mount) - this has transpired due to split bushes, or a broken mount. Many owners opt to upgrade to the Mk8.5 lower torque mount which is slightly different, and a huge upgrade that does not incite NVH. Please note - the Mk8.5 Uprated Torque Mount must be supplied with the associated bracket you can see in our listing here.
6. Conclusion
The Ford Fiesta ST Mk8 offers excellent performance and a fun driving experience, with the added benefit of modern tech and a range of trims to suit different preferences. Whether you choose the standard ST, the well-equipped ST-2, or the fully-loaded ST-3, the Fiesta ST Mk8 delivers a thrilling drive that’s hard to beat in its class. If you’re considering a used model, check the suspension, engine, and brakes, and always request a full service history. The Mk8.5 facelift provides a few useful updates, but the core performance remains largely the same.
Ultimately, the Fiesta ST Mk8 is a great choice for anyone looking for a practical yet exciting hot hatch. By keeping these points in mind, you can ensure that you make the right choice when buying your Fiesta ST.
