Developed from the Leyland 400 series, it produced roughly 138 bhp at 2,600 rpm. Today, "401" more commonly refers to Ashok Leyland's modern heavy-duty trucks (e.g., U 4019 and 4019 series). [1, 2, 3, 4, 5] Heritage: Leyland 400 Series (1960s–1980s) Origins: As an evolution of the Leyland 400, the 401 engine was originally produced in the UK for the Guy Big J and related Leyland vehicles. It used Butec electricals and was celebrated for its lighter weight. [1] Indian Adaptation: Through Ashok Leyland's deep-rooted historical ties with British Leyland, the engine technology laid the groundwork for robust, reliable medium-duty trucks in the Indian commercial vehicle market. [1, 2] Modern Era: 40-Tonne Heavy Haulage (2000s–Present) In the modern context, "401" does not refer to a specific engine displacement, but rather to the 40-tonne Gross Vehicle Weight (GVW) and tractor-trailer ranges manufactured by the company (such as the Ashok Leyland U 4019). [1, 2] Engine Tech: These modern 40-tonne vehicles are powered by Ashok Leyland’s indigenous 5.7L 6-cylinder H-Series engines. Performance: They deliver up to 180 hp at 2,400 rpm and 660 Nm of torque, utilizing modern CRS and iEGR technologies to meet strict environmental norms. [1, 2, 3, 4]
