Horse Powertrain, a global leader in low-emission propulsion systems, has invested 45 million euros to expand cylinder head casting processes at its plant in Valladolid, Spain. The new aluminium casting facility will be the first in the country to cast cylinder heads using the innovative tilting gravity die casting (TGDC) process. Compared to traditional high-pressure die-casting methods, this new process significantly enhances the structural integrity of the finished components — an essential requirement for high-efficiency hybrid engines.
Following this investment coming online, Valladolid’s annual production capacity for cylinder heads will rise from 300,000 to 360,000 — a 20% increase — and will create 150 new permanent roles at Valladolid.
Beyond the technological improvements, the new facility enables Horse Powertrain, through its Horse Technologies division, to further internalise component production, enhancing the business’s autonomy and further improving quality control at the Valladolid plant.
Patrice Haettel, COO of Horse Powertrain and CEO of Horse Technologies, said: “This new facility not only introduces a new process to Spain, but also further demonstrates Valladolid’s leadership as a world-class automotive plant. By adding this innovative technology to our capabilities, we are growing our production capacity and increasing our flexibility as a business. This milestone is the direct result of the talent and commitment of our team, as well as the support of regional institutions that continue to invest in the industrial future of Castilla y León.”
In December 2025, the Junta de Castilla y León declared the newly announced investments — which are associated with the development and manufacture of new propulsion systems — to be a ‘priority industrial project’. This new facility forms part of the company’s ambitious long-term plan in Spain.
