Its e-services portfolio includes enhanced digital fleet solutions, depot infrastructure, and turnkey electrification support services to its customers.

Our press visit to BorgWarner’s cutting-edge Gigafactory in Darmstadt, Germany revealed a company that is rapidly accelerating toward the future by betting big on electrification!

Kontrolmatik has agreed to deliver 2 GWh of cells in 2026 and 5 GWh in 2027 to ONE, which will assemble them in battery modules and packs in Michigan.

Readers may recall that, two years ago, we published a feature on TCCI Manufacturing, explaining why the longstanding Midwest supplier of compressors had decided to invest in a new facility on its home turf in Decatur, Illinois. In that article, Richard and Kara Demirjian outlined their plan to open a 260,000-square-foot “Clean Energy Innovation Hub” comprised of three facilities: a plant dedicated to the production of compressors for electric vehicles; a whole-vehicle test centre; and an academy to train the next generation of EV technicians. The innovation hub was officially unveiled by the governor of Illinois, JB Pritzker, at the end of April 2025, and so Truck & Bus Builder used the Advanced Clean Transportation Expo to get an update on TCCI’s newest investment.

This accreditation means the bus can operate “on a planned route without a driver in the cab,” significantly expanding Karsan’s autonomous e-bus operations beyond existing deployments in Italy,  Switzerland and Finland.

Spheros, the specialist in heating, air conditioning, and thermal management systems for buses, has been independent from its former parent Valeo for nearly a year now, and company CEO Mark Sondermann wants people to know it. “We are no longer constrained by the strategic priorities of a larger group,” he told Truck & Bus Builder. “There is now only one priority, and that’s Spheros.” Following the Valeo acquisition in 2016, Spheros adopted its parent’s name; the reclamation of its own name marks a definitive break with the recent past. And the change is a timely one: “We can now be more agile. We can take faster decisions. It gives us the room to act in this very exciting and very dynamic market.”

No specifics about the partnership have been released, except that the first products are set to be unveiled in the spring of 2026.

Based in Sfax, Tunisia, KPIT engineering SUARL currently employs 574 people and functions as a dedicated nearshore development centre

Rocsys says its portfolio of products and services are intended to simplify the introduction and scaleup of autonomous charging operations.

The technology uses renewable and recycled materials which exhibit “exceptional mechanical properties”, making the brake pads more reliable as well as more sustainable, according to Tenneco.

This year’s edition of the Advanced Clean Transportation Expo featured a more balanced range of driveline technologies, from battery and fuel cell electric at one end of the scale to propane, natural gas, and hydrogen combustion at the other. However, decarbonising the internal combustion engine is not as simple as replacing diesel with a different fuel; the different combustion characteristics of natural gas and hydrogen require alterations be made to the engine so that it works optimally with the new fuel type. One company which has thought long and hard about how to make these necessary tweaks is Eaton Corp. Scott Adams, who is senior vice president of technology and global products for Eaton’s Mobility Group, guided Truck & Bus Builder through the company’s portfolio, showing cutting-edge prototypes as well as its established range of power management technologies.

After attending the Advanced Clean Transportation Expo in the past two years, we were of the view that the USA may catch up with Europe to become the world’s largest electric vehicle market after China. Following the 2025 edition of the ACT Expo – held between 28 April and 1 May in Anaheim, California – I now have serious doubts about how long it will take for America to overtake Europe, if it happens at all. There was a palpable shift away from electric vehicles in favour of alternatives such as natural gas, propane, and hybrid vehicles. Once the stars of the show, these options faded into the background when California’s zero emission vehicle mandate passed into law. Now, the progressive state has repealed the mandate, after the Environmental Protection Agency in January 2025 withdrew the waiver which allowed California to enforce zero emission quotas on fleets; consequently, the low-emission alternatives to diesel and electric are enjoying a revival of interest from many kinds of customer.
