About the Rolls-Royce 10 hp
The Rolls-Royce 10 hp was the first model produced following the historic 1904 agreement between Charles Rolls and Henry Royce. Developed from Royce's earlier prototypes, it was engineered to be significantly quieter and more refined than contemporary rivals, establishing the brand's reputation for 'silent' luxury. The car features the iconic triangular-topped radiator that became a permanent hallmark of the marque. Only 16 units were completed before production shifted to larger multi-cylinder engines, making it one of the rarest and most significant collector cars in existence.
