The Toyota GD engine series is a diesel engine produced by Toyota which appeared in 2015. It replaced the Toyota KD engine series as a diesel engine series mainly oriented to body-on-frame vehicles. The GD engine featured Economy with Superior Thermal Efficient Combustion (ESTEC) technology. Toyota claims they have a maximum thermal efficiency of 44 percent, "top class" at the time of introduction.
The GD engine series is produced in three countries: in Japan, in Bangalore, India by Toyota Industries Engine India (TIEI), and in Chonburi, Thailand by Siam Toyota Manufacturing (STM).
1GD-FTV
The 1GD-FTV is a straight-4 common rail diesel engine with a variable nozzle turbocharger (VNT), chain drive and Intercooler. It has 16 valves and a DOHC (double overhead camshaft) design. Its compression ratio is 15.6:1. Bore x stroke is . It generates at 3,400 rpm, and of torque at 1,600-2,400 rpm when mated to a 6-speed automatic transmission, depending on target market and emission specifications. With manual transmission, outputs are and . In 2020, the power and torque figures for some models were uprated to at 3,400 rpm and at 1,600–2,800 rpm. Average fuel consumption (in JC08 method) is .
For the Toyota HiAce (H200), the engine is detuned to at 3600 rpm and of torque at 1000-3400 rpm mated to a 6-speed automatic transmission. For the South African, Australian and New Zealand Hilux GR Sport, and the 2023 Thai Fortuner GR Sport models, the engine is further uprated to produce and of torque.
