Siemens Digital Industries Software announced today that Tremonia Mobility GmbH, a leading manufacturer of minibuses, has adopted Siemens Xcelerator to accelerate the electrification and to optimize the development of its products for public transport, shuttle, and travel services.
Tremonia Mobility, originally part of Daimler Corporation, has produced over 25,000 premium minibuses for various services and became an independent company in 2022. The company is dedicated to designing environmentally friendly, efficient, and customizable minibuses.

“The decision to use Siemens Xcelerator is the result of a clear goal: we want to act faster while remaining cost-effective,” says Josa Prinz, chief executive officer (CEO) and chief technology officer (CTO) at Tremonia Mobility. “The design and engineering capabilities in Siemens Xcelerator enable us to document parts, components and 3D layouts more efficiently concerning breadth and depth and streamline and make processes more agile.”

The combination of design tools from the Siemens’ Designcenter suite has enabled Tremonia Mobility to improve its process optimization, creating an ideal solution set for a medium-sized company. This not only facilitates onboarding employees but also allows Tremonia Mobility to respond more efficiently and flexibly to customers’ needs. With the Siemens Xcelerator software available across its global design teams in Dortmund, Germany, and India, Tremonia Mobility has sped up design cycles by 20 percent and increased the speed of design adjustments by 30 percent.
“We have high standards for our production and quality checks, and in how we design and fulfil the customer requirements,” says Christian Wünsch, head of research and development (R&D) and product management at Tremonia Mobility. “We specialize in city buses, which normally require meeting high standards, such as safety assists, passenger information systems and interior design. Using Siemens Xcelerator is also beneficial due to its embedded synchronous technology, which enables us to do part changes quickly. This helps because we are working with large amounts of data and legacy data.”

“The future of mobility lies in efficient, sustainable solutions, and our buses precisely meet these requirements,” says Prinz. “Adapting to alternative drives and reducing emissions are challenges we actively address. With a broad spectrum of customers, from small bus companies to municipalities, we are on a good path to establishing ourselves globally. The partnership with Siemens and the use of design tools are a good start, but the expansion and deepening of this collaboration are still ahead. A broader integration of Siemens tools, for example, optimizing upstream and downstream processes, is part of our future focus.”
