Ciudad Obregón fires up its first electric motor: Cajeme's urban transit enters a new era
Cajeme unveiled its first 100% electric bus: low floor, 27 passengers, 320 km of range, and a project for 30 units rolling out in two phases. Grupo Berumen stands beside the transition.

The silence of a motor that doesn't pollute was the most powerful signal left by the unveiling of a 100% electric bus in Cajeme. No smoke, no excessive noise, no diesel: only technology, efficiency, and the certainty that urban transit in Ciudad Obregón has a clear road into the future.
The vehicle on display —a low-floor model with capacity for 27 passengers, two automated doors, air conditioning, and an accessibility ramp for older adults and people with disabilities— is not a distant promise. It is the prototype of what could become 30 units operating on the municipality's busiest routes.
A project with a concrete roadmap
Luis Enrique Meneses, director of Transportes Dinámicos del Noroeste, presented a proposal that contemplates rolling out these 30 electric units in two phases of 15 buses each. The first batch would serve Route 3, with progressive expansion to routes 7 and 8.
With a range of approximately 320 kilometers per charge, each unit can cover full operational shifts without needing a mid-day recharge — eliminating one of the main arguments against the mass adoption of electric fleets in mid-sized cities like Ciudad Obregón.
The project is in the analysis phase and requires state approval as well as financial backing to move forward. But the direction is clear: gradually replacing diesel units with electric vehicles that reduce polluting emissions and raise the quality of service for riders.
Grupo Berumen: where Sonora's vision meets mobility technology
For Grupo Berumen, this presentation is not foreign news: it is the territory where we have been operating for years.
As the authorized distributor of Hyundai and Volvo commercial vehicles in Sonora —including electric and hydrogen-powered lines— we know that the energy transition in transportation is not a global trend that "will arrive someday." It is already here. And Sonora has the opportunity to position itself as a national reference point for sustainable mobility.
Mr. Jesús Antonio Berumen Preciado, CEO of Grupo Berumen, puts it plainly:
"What we are witnessing in Ciudad Obregón is exactly the kind of transformation that Sonora needs and deserves. Modernity is not just about adopting technology: it is about making decisions that improve people's lives today and protect the territory's resources for the generations to come. At Grupo Berumen we have spent years preparing to be the bridge between that vision and real-world operation. Electric and hydrogen vehicles are not the future of transportation in our region — they are the present we are building together."
Why this matters beyond the bus
| Indicator | Traditional diesel bus | Electric bus (projected) |
|---|---|---|
| CO₂ emissions per km | ~1.1 kg | 0 kg (operation) |
| Fuel cost / day (approx.) | $800–1,200 MXN | $180–280 MXN (electric charge) |
| Annual maintenance | High (combustion engine) | Significantly lower |
| Rider experience | Noise, vibrations | Quiet, climate-controlled, accessible |
| Range | Unlimited (with diesel available) | ~320 km per charge |
The transition is not only environmental. It is financially superior in the medium term for operators, and qualitatively superior for riders from day one.
Sonora's moment
Ciudad Obregón has the opportunity to become the first city in northwest Mexico to operate a massively electric urban transit fleet. That is not only an environmental advantage: it is a competitive advantage to attract investment, talent, and recognition as a forward-looking municipality.
At Grupo Berumen we are ready to be an active part of that transformation —from technical advisory to the supply of commercial electric vehicles already operating in other markets across the country and the world.
