The 1HD-FT is a Template:Convert straight-6 24 valve SOHC turbocharged direct injection diesel engine. Bore and stroke is Template:Convert, with a compression ratio of 18.6:1. Known as the "multivalve" it has 4 valves per cylinder (2 inlet, 2 exhaust), central vertically mounted injector, and no glow plugs but rather an intake glow screen heater (like the later electronic 1HD-FTE below). The 4 valves per cylinder are actuated by the SOHC, by using bridges so each rocker actuates a pair of valves. Output is Template:Convert ECE at 3,600 rpm with Template:Convert of torque ECE at 2,500 rpm. However, marinized version of 1HD (sold as Yamaha ME and Yanmar 6LP) have an output of Template:Convert on Yanmar 6LP and Template:Convert, Template:Convert or Template:Convert on Yamaha ME.[2][3][4][5]

Output is Template:Convert at 3,400 rpm with Template:Convert of torque at 1,400 rpm. The fuel system is direct injection, and adopts the electronic fuel injection (EFI) system. Redline of this engine is at 4200 rpm.
The 4 valves per cylinder are actuated by the SOHC, by using bridges so each rocker actuates a pair of valves.
The version with intercooler as fitted to HDJ100 station wagons has Template:Convert at 3400 rpm with Template:Convert of torque at 1200-3200 rpm with a redline reaching 4200 rpm. A lower output Template:Convert non-intercooled version powers HDJ78 Troop Carrier and HDJ79 Utility versions.
Also some of the HDB50 and HDB51 Coasters are fitted with this 1HD-FTE engine.
