Villefranche-sur-Saône. Greenmot starts converting diesel city buses into electric buses


'In connection with the greening of passenger transport fleets, the Prime Minister decided through the General Secretariat for Investments, in accordance with the requirements of the Mobility Orientation Act and the Energy Transition Act, to support the Green eBus project,' explains the press release. “Greenmot is thus integrated into the Future Investments Program (PIA) implemented by Ademe and benefits from financing of more than EUR 1 million. This amount supports the project to manufacture a prototype for converting a diesel city bus into a battery-powered electric drive bus, ”the press release emphasizes.

“By converting the diesel buses from existing fleets to electric buses, the energy transition can be accelerated through the fast and cost-controlled redesign of a large part of the current vehicle fleet. The converted buses can thus - in the middle of life - continue to be operated in all urban networks, especially in those with low-emission zones (ZFE). This extension of the service life of existing buses will make it possible to upgrade the current diesel fleets, extend their service life and thus optimize the budget for public transport. to control the costs of setting up low-emission zones (ZFE) ”.

The project integrates the development of a battery with Greenmot technology.

Establishment of an industrial production center at the Villefranche-sur-Saône plant

The duration of the development project for the first prototype is 18 months. An industrial manufacturing center will then be set up at the Villefranche-sur-Saône plant and the customer service center will be reinforced.

Stéphane Londos explains the topic: 'This project opens up an industrial opportunity for Greenmot in which several regional partners will create a French retrofit sector with strong export potential.'

This project is therefore “the first stone in the creation of a development center for special industrial vehicles that combines the energy transition and the control of the special features of special vehicles. The implemented skills will then make it possible to turn to other energies such as hydrogen. '

The project 'is not limited to building the kit, it is a global approach to recycling disassembled parts, either by reusing parts or recycling materials,' the press release concludes.

The founder

Stéphane Londos founded Greenmot in October 2010. He was trained at ECAM Lyon and then at IFPEN and spent his career at PSA and then at Faurecia as an innovation manager. With 20 years of experience in the automotive world and engine research and development, he has created innovative test facilities to meet new business needs.

The team

Around Stéphane Londos, three design offices and an operations department bring together specialist knowledge of vehicle, energy and heat management, innovative project management and the industrialization of test and development processes.


The determination of possible sources of improvement for a vehicle in order to reduce consumption is the task of Greenmot.

Greenmot is a test center and design office for all types of motorized vehicles, from automobiles to special military vehicles. Since it was founded, the company has developed its own cells and test tools and today offers four climate test cells of different sizes.

The companys strategy is divided into three poles that work synergistically:

- the testing department, which designs and performs tests based on customer specifications (running tests, fuel consumption, pollution, transmission tuning, vehicle comparison, etc.) and executes premium vehicle testing equipment;

- The engineering department that designs, assembles and installs air conditioning cells and test benches for customers, organizes the transfer of technology to respond to energy changes in vehicles, designs and manufactures certain products related to tests: torque sensors and high-precision driving robots.

- The manufacturing department, responsible for the development of high-performance battery solutions for mobility and vehicle retrofitting

Today the company employs around 60 people - including 40 engineers - in two test centers in Villefranche-sur-Saône.
