The World’s Fastest Fiesta ST
Our Record-Breaking Devine Autotech Mk7 Drag Car
This isn’t a “fast for a Fiesta” story. This is the fastest Fiesta ST in the world over the quarter mile – and it’s our car.
Built in-house at Devine Autotech, this Mk7 Fiesta ST was never intended to be a road car, show car or dyno queen. It was built for one purpose only: to go faster than any other Fiesta ST on the planet.
That goal was achieved and documented when the car featured in Fast Ford Magazine’s Fiesta Special as the world record-holding Fiesta ST.
Built With Purpose, Not Compromise
From day one, the approach was simple: reduce weight, reinforce where it matters, and deliver power that could be used reliably.
The car was stripped back to a bare shell. Anything that didn’t directly contribute to performance was removed. No sound deadening, no interior comforts, no unnecessary systems – just a lightweight, functional platform designed specifically for drag racing.
This allowed full focus on traction, drivetrain efficiency and repeatable performance rather than chasing headline numbers.
Engine & Power Setup
At the heart of the build is a heavily developed 1.6 EcoBoost ST180 engine, designed to withstand extreme cylinder pressure and repeated high-load runs.
- Strengthened bottom end with forged internals
- Lined engine block for added durability
- Large-frame turbocharger setup
- Tubular exhaust manifold
- Secondary injector system for increased fueling capacity
- Custom drag-focused ECU calibration
The setup is capable of producing over 500bhp, while remaining consistent and reliable. This build was never about peak dyno figures, but about terminal speed, traction and repeatability.
Transmission, Suspension & Traction
Delivering this level of power through a front-wheel-drive platform is where most builds struggle. Making it work consistently is where the real engineering begins.
- Purpose-built drag suspension
- Lightweight wheels with dedicated drag tyres
- Upgraded drivetrain components for repeated launches
- Weight transfer setup optimised for maximum grip
Every decision was made with one goal in mind: how the car leaves the line and carries speed through the quarter mile.
The Result – A World Record Fiesta ST
All of this work paid off. The car went on to become the fastest Fiesta ST in the world over the quarter mile, setting a benchmark for the platform on a global scale.
It’s proof that, when built properly, the Fiesta ST is capable of far more than most people ever expect.
Why This Build Matters
This car represents exactly how we approach everything at Devine Autotech. No shortcuts, no guesswork, no chasing hype figures – just data, testing and results.
Whether it’s a world record drag car or a customer build, the same principles apply. Build it properly, or don’t build it at all.
