Our story

mountune was founded by David Mountain in Maldon, Essex, initially building A Series Mini engines for private competitors in minicross, autocross and rallycross. What began as a small competition engine business established the engineering principles that continue to define mountune today.

A meeting with Terry Hoyle, then responsible for Ford’s works rally engines, opened the door to a relationship that would shape the next chapter of mountune. From this point, Ford competition engines became an increasingly important part of the business.

Working with Robb Gravett, mountune developed and built engines for his Group N production saloon programme. Success followed quickly, with two championship titles helping establish mountune within Ford competition and bringing a growing number of customer programmes to the business.

Robb Gravett secured the 1990 British Touring Car Championship in the mountune powered Ford Sierra RS500. The title represented a major milestone for mountune and established its Cosworth engine expertise at the highest level of British touring car competition.

mountune’s relationship with Ford developed into a works rally engine programme, including the 2 litre YB powering the Escort RS Cosworth. François Delecour’s victory at the 1994 Monte Carlo Rally delivered Ford its first works victory at the event in more than 40 years.

Colin McRae won the Safari Rally in the mountune powered Ford Focus WRC, delivering one of the defining results of mountune’s works rally programme. By this point, mountune had been developing and building Ford rally engines for close to a decade.

mountune became the sole engine supplier to Formula Palmer Audi, beginning a relationship that would continue for 12 consecutive seasons. Every car on the grid ran a mountune built engine, demonstrating the reliability and consistency required of a complete one make championship.

For the relaunch of the FIA Formula Two Championship, mountune was responsible for the build, supply and support of every engine on the grid. The turbocharged 1.8 litre Audi based units produced approximately 500 bhp and were developed for the demands of a single specification international championship.

The limited edition Ford Focus RS500 marked an important step in mountune’s relationship with Ford road cars, with a mountune intercooler fitted as original equipment. It demonstrated how engineering developed through performance and competition could be applied directly within a manufacturer production programme.

Development expanded across Ford’s EcoBoost engine family, bringing mountune’s engineering experience to a new generation of road and competition applications. EcoBoost technology subsequently became central to both mountune performance products and racing programmes.

Ash Sutton secured the BTCC Drivers’ Championship in the Subaru Levorg, powered by a mountune built 2 litre turbocharged boxer engine. Developed specifically for the programme, the engine demonstrated mountune’s ability to apply its expertise beyond its traditional Ford based platforms.

mountune was appointed engine partner for the GB4 Championship, extending an existing relationship with MSV as engine partner to GB3. The programme brought mountune power to another complete single seater grid, with the inaugural GB4 season beginning in 2022.

The introduction of new machinery across GB3 and GB4 brought a new generation of mountune engines. GB3 adopted a normally aspirated 2 litre producing 280 bhp, while GB4 moved to its own normally aspirated 2 litre package, continuing mountune’s role as engine partner across both championships.

More than four decades after mountune was founded, competition remains central to what we do. In 2026, mountune power has already helped secure three BTCC championships, alongside the British Hillclimb Tin Top Championship, while every car competing in GB3, GB4 and FC2 continues to run with mountune power.

The engineering behind these programmes also supports our work with manufacturers and the development of mountune performance products, connecting what we do today with the experience built through more than 45 years of competition.
