We don’t forget our origins…
Founded in 1966 by Biscayan entrepreneur José María Gutiérrez Ascunce, Guascor was created with a clear purpose: to supply the industrial and marine sectors with reliable, efficient engine solutions.
Over the decades, we have evolved into a global manufacturer of gas and diesel engines, engineered for power generation, cogeneration, waste-to-energy applications, and marine propulsion, all built on the company’s own proprietary technology.
…but we continue to make history
2026 marks six decades of innovation at Guascor Energy. Since 1966, our solutions have been engineered to meet demanding operational requirements and deliver reliable performance. This year, we honor a legacy built on technology, expertise, and commitment — while looking ahead to a future defined by efficiency, sustainability, and technological excellence.
