It’s in the design

One of the standout features of HPDI is its seamless integration into existing vehicle architectures. This design choice not only facilitates easier and more cost-effective adoption but supports Cespira’s ambition to leverage existing resources in novel ways to advance global climate goals faster.

Our technology
“The Cespira H2 HPDI technology left us very impressed. Its high efficiency, powerful performance, and the potential of long-range operations is a very attractive solution. Our confidence is bolstered by its foundation on a traditional powertrain, ensuring minimal investment in new workshop facilities. Additionally, the adaptability of the system to biogas is a significant advantage, aligning with our vision of fuel self-sufficiency because we can utilize local biomass and excess electricity, transforming them into fuel for our truck fleet. ”
