Komatsu and Williams Racing Unite to Drive Hybrid Technology Forward

Komatsu, a global leader in mining, construction, and forestry machinery, employs over 65,000 people worldwide and has pushed innovation for more than a century. The Japanese company pioneered the first hybrid hydraulic excavator back in 2008 and continues to lead in electrification and hybrid systems.

This commitment to cutting-edge technology has sparked a renewed partnership with the iconic British Formula 1 team, Williams Racing. Their collaboration dates back to the 1990s when Komatsu produced gearbox parts for championship-winning Williams cars. Today, the partnership focuses on shared values, talent development, and striking parallels between their technologies.

At first, Komatsu’s 37-tonne HB365LC-3 excavator and the Williams FW47 Formula 1 car may seem worlds apart. However, both machines rely on advanced hybrid systems designed to maximize power and efficiency.

The HB365LC-3 features an electric swing motor paired with a six-cylinder engine. This motor captures energy when the machine slows down, converting it into electricity stored in a capacitor. This stored energy supports acceleration and the swing function, reducing fuel consumption significantly. Komatsu’s century-long expertise in electrification also extends to electric mining trucks, wheel loaders, and shovels, with a clear vision toward next-generation autonomous and power-agnostic mining equipment.

Similarly, the Williams FW47 F1 car uses a hybrid system with a V6 engine supported by two Motor Generator Units (MGUs). The MGU-k recovers kinetic energy during braking, storing it in batteries for powerful acceleration out of corners. The MGU-h captures heat energy from exhaust gases, which either recharges the battery, assists propulsion, or boosts the turbocharger. This hybrid setup makes the FW47 one of the most efficient internal combustion engines on the planet, with future regulations pushing hybrid power usage even higher by 2026.

Beyond technology, Komatsu and Williams jointly invest in engineering talent development. The Komatsu-Williams Engineering Academy offers global youth access to mentorship, internships, and resources that help inspire the next generation of engineers and innovators.

Together, Komatsu and Williams are shaping the future of hybrid engineering, combining forces to deliver powerful solutions—whether in harsh mining environments or at the pinnacle of motorsport. Their partnership demonstrates how advanced hybrid technology can optimize performance, efficiency, and sustainability across industries.
