Fourth edition showcases OEM partnerships and real-world machine performance powered by Rehlko diesel engines.

REGGIO EMILIA, Italy – July 14, 2026 – Rehlko welcomed members of the European trade press to its headquarters in Reggio Emilia for the fourth edition of Demo Days, the company's annual event dedicated to demonstrating the performance of its engines where it matters most: in the machines they power. Held on July 13–14, the event brought together six OEM partners—Cormidi, MDB, Palfinger, Vermeer, Wacker Neuson and Weidemann—who showcased nine machines across a wide range of off-highway applications. Unlike a traditional product presentation, Demo Days gives journalists the opportunity to experience these machines firsthand, evaluating engine performance under real operating conditions and engaging directly with OEMs, engineers and product specialists. The highlight of this year's event was the debut of the new KDI 1903TCR HP (High Power), the latest evolution of Rehlko's proven KDI platform. Developed to meet the growing demand for higher performance in compact machines, the new KDI 1903 HP delivers up to 50 kW (67 hp) and 250 Nm of torque, offering OEMs increased productivity without compromising the compact footprint and installation flexibility that have made the KDI family a benchmark in the off-highway market. Fully compliant with EU Stage V emissions regulations, the engine integrates Rehlko's advanced aftertreatment technology while maintaining low operating costs through extended service intervals and outstanding fuel efficiency. Compatibility with 100% HVO renewable fuel further supports OEMs looking to reduce lifecycle CO₂ emissions without redesigning their machines. "The best way to understand an engine isn't to read about it—it's to experience the machine it powers," said Eric Fontaine, President of Rehlko Engines. "Demo Days reflects the way we work with our OEM partners every day. We engineer engines as part of a complete machine, helping our customers deliver greater productivity, reliability and value to the people who depend on their equipment." Alongside the introduction of the new KDI 1903 HP, attendees also experienced Rehlko's complete diesel portfolio in action. The KSD family, Rehlko's latest-generation diesel platform, continues to expand across construction, material handling and industrial applications, combining compact dimensions, excellent power density and low total cost of ownership. Since its introduction, KSD has emonstrated significant customer benefits, including reduced fuel consumption, faster machine response and dependable performance in demanding operating environments. The event also featured applications powered by the established KDI 1903TCR, one of Rehlko's most successful diesel engines. Designed for global off-highway markets, the engine combines robust heavy-duty architecture, high power density and Rehlko's Smart After-Treatment System to meet the latest emissions standards while delivering excellent reliability and long service intervals. More than a product showcase, Demo Days highlighted the close engineering collaboration between Rehlko and its OEM partners. Every machine on display demonstrated how engine integration, application engineering and shared product development contribute to higher machine performance, simplified installation and greater value for end users. Now in its fourth year, Demo Days has become a key event for the European off-highway industry, offering journalists a unique opportunity to move beyond specifications and experience the technologies they report on in real working conditions. The event also reflects Rehlko's commitment to a simple philosophy: Powering machines. Empowering OEMs.

By combining innovative diesel technology with engineering partnership, global service support and application expertise, Rehlko continues to help OEMs build machines that outperform the competition across construction, agriculture, material handling and industrial applications.
