Horse Powertrain Invests €45m to Expand Valladolid Plant

Horse Powertrain, a global leader in low-emission propulsion systems, has invested €45 million to expand cylinder head casting processes at its Valladolid plant in Spain.

The new aluminium casting facility will be the first in Spain to cast cylinder heads using the Tilting Gravity Die Casting (TGDC) process. The TGDC process improves the structural integrity of finished components compared with traditional high-pressure die casting. This strength supports the demands of high-efficiency hybrid engines.

Once the investment comes online, Valladolid will increase annual cylinder head production capacity from 300,000 to 360,000 units, a 20% rise. The expansion will create 150 new permanent roles in Valladolid.

The new facility also supports stronger in-house manufacturing. Horse Powertrain, through its Horse Technologies division, will internalise more component production, increase operational autonomy, and tighten quality control at the Valladolid plant.

Patrice Haettel, COO of Horse Powertrain and CEO of Horse Technologies, stated:
"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 expanding our production capacity and increasing our business flexibility. 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 (PIP). The new TGDC facility supports the company’s ambitious long-term plan in Spain and strengthens its hybrid engine supply chain.
