What is Mountune?

A British performance-tuning company specialising in Ford models, offering factory-backed power upgrades for cars like the Fiesta ST and Focus RS.

Mountune is a UK-based engineering and tuning firm with deep roots in motorsport, having built engines for rallying and racing for decades. It is best known among enthusiasts for its performance upgrades for fast Fords, particularly the Fiesta ST, Focus ST and Focus RS.

What sets Mountune apart is its close, semi-official relationship with Ford.

Typical packages add boost, revised software and uprated hardware for meaningful gains.

Beyond Ford, Mountune has expanded into upgrades for other performance models and continues its motorsport engineering work. Its blend of warranty-friendly tuning and racing pedigree has made it a trusted name in the hot-hatch community.
