Sisu is a Finnish heavy vehicle brand whose name was chosen to express a distinctly Finnish idea of determination, endurance, and resilience. The company traces its roots to Oy Suomen Autoteollisuus Ab, established in 1931, with Sisu vehicles appearing in the early 1930s as Finland developed its own commercial vehicle production.
The brand identity has long relied on a bold SISU wordmark, usually rendered in red, emphasizing strength and utility rather than decorative symbolism. Its branding has remained closely tied to trucks, military vehicles, and demanding northern operating conditions.
