electric retrofit and sustainable mobility
Electric retrofit: transform your combustion-engine vehicle into a high-performance, sustainable solution
Converting a combustion-engine vehicle to electric power is not simply a matter of replacing the engine. It is a far-reaching transformation that involves rethinking the entire vehicle: its architecture, its dynamic behaviour and its energy management.
At RUN FUN & XAP, retrofitting is approached as a genuine engineering project. Each conversion is designed to meet real-world usage requirements – sometimes extreme – where reliability cannot be compromised.
The aim is simple: to offer an electric solution that can be used straight away, without compromising on performance.
A comprehensive approach of retrofit
In its simplest terms, retrofitting involves replacing an internal combustion engine with an electric propulsion system. But this view is far from complete.
In practice, every project involves a series of complex technical trade-offs. It is necessary to integrate a motor suited to the vehicle’s intended use, design a suitable battery system, manage thermal constraints, and recalibrate the entire system to ensure stable and reliable performance.
This work cannot be treated as a simple mechanical operation. It relies on a detailed understanding of the entire vehicle system. It is precisely this holistic approach that makes the difference between a functional conversion… and a solution that is genuinely viable in real-world conditions.
Expertise drawn from practical experience and motorsport
The RUN FUN approach draws directly on methods derived from motor racing and projects carried out in demanding environments.
This experience fundamentally changes the way a retrofit is designed. Technical choices are not guided solely by theoretical or regulatory constraints, but by the realities of use: thermal constraints, real-world range, performance under load, and long-term durability.
In particular, some projects have been undertaken in extreme conditions, such as desert environments or competitions, where every failure has immediate consequences.
This real-world feedback now enables us to design robust solutions capable of operating where more standard approaches reach their limits.
A wide range of practical applications
Retrofitting comes into its own when the aim is to balance performance, sustainability and adaptation to a specific use.
It is relevant to projects in the motorsport sector as well as to sustainable mobility initiatives led by local authorities or industrial players. It also makes it possible to optimise existing fleets without having to purchase new vehicles, whilst meeting current regulatory requirements.
In these contexts, retrofitting is no longer limited to an environmental approach. It becomes a genuine tool for technical adaptation, capable of extending the life of vehicles whilst bringing them into line with current requirements.
Reliability proven in real-world conditions
One of the key challenges of retrofitting remains reliability. And in this respect, the difference is rarely evident on paper.
The solutions developed by RUN FUN have been tested under real-world conditions, which can sometimes be particularly demanding: heat, sand, intensive use and limited battery life. These environments impose high standards, far exceeding those of standard tests.
This validation process ensures that performance meets expectations in the field, rather than being based solely on simulations or assumptions.
Tailor-made support
Every retrofit project is unique. Technical constraints, operational objectives and levels of involvement vary significantly from one client to another.
That is why RUN FUN offers flexible support, ranging from technical design through to full implementation, right up to the delivery of vehicles ready for operation. The service may also include technical support in real-world conditions, to ensure the project’s continuity and performance over time.
This flexibility enables us to integrate effectively into a wide variety of projects, whilst maintaining high technical standards.
A forward-looking vision
Retrofitting is now emerging as a practical response to environmental and economic challenges. It enables us to make the most of existing assets, reduce our carbon footprint and avoid the systematic replacement of vehicles.
But beyond these benefits, above all it paves the way for a new approach to mobility: one that is more adaptable, more sustainable and better aligned with real-world usage.
At RUN FUN, this vision translates into a clear ambition: to make retrofitting not merely a fallback solution, but a genuine driver of performance and innovation.
