| Predecessor | Toyota KD engine |
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.[1] Toyota claims they have a maximum thermal efficiency of 44 percent, "top class" at the time of introduction.[2]
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).[3][4]

The 1GD-FTV is a 2,755 cc (2.8 L) straight-4 common rail diesel engine with a variable nozzle turbocharger (VNT), chain drive and Intercooler.[5] It has 16 valves and a DOHC (double overhead camshaft) design. Its compression ratio is 15.6:1. Bore x stroke is 92 mm × 103.6 mm (3.62 in × 4.08 in). It generates 180 PS (178 hp; 132 kW) at 3,400 rpm, and 450 N⋅m (332 lb⋅ft; 46 kg⋅m) 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 177 PS (175 hp; 130 kW) and 420 N⋅m (310 lb⋅ft; 43 kg⋅m).[6] In 2020, the power and torque figures for some models were uprated to 150 kW (201 hp; 204 PS) at 3,400 rpm and 500 N⋅m (370 lb⋅ft; 51 kg⋅m) at 1,600–2,800 rpm.[7] Average fuel consumption (in JC08 method) is 11.2 km/L (8.9 L/100 km; 26 mpg‑US).[8]
For the Toyota HiAce (H200), the engine is detuned to 150 PS (148 hp; 110 kW) at 3600 rpm and 300 N⋅m (221 lb⋅ft; 31 kg⋅m) of torque at 1000-3400 rpm mated to a 6-speed automatic transmission.[9] For the South African, Australian and New Zealand Hilux GR Sport,[10] and the 2023 Thai Fortuner GR Sport models,[11] the engine is further uprated to produce 165 kW (221 hp; 224 PS) and 550 N⋅m (410 lb⋅ft; 56 kg⋅m) of torque.
For the Toyota Dyna and Hino 200, the engine is detuned to 106 kW (142 hp; 144 PS).[12][13]
A 48-volt mild hybrid variation was introduced in August 2023.[14]
For marine application (Yanmar 4LV), the engine generates up to 250 hp (253 PS; 186 kW) at 3800 rpm.[15]

The 2GD-FTV is a 2,393 cc (2.4 L) straight-four common rail diesel engine with a variable nozzle turbocharger (VNT) and intercooler.[30] It has 16 valves and a DOHC (double overhead camshaft) design. Its compression ratio is 15.6:1. Bore x stroke is 92 mm × 90 mm (3.62 in × 3.54 in). It generates 150 PS (148 hp; 110 kW) with intercooler at 3400 rpm, and 400 N⋅m (295 lb⋅ft; 41 kg⋅m) of torque at 1600-2000 rpm when mated to 6-speed automatic transmission or manual transmission, depending on target market and emission specifications.[31][32]
In the second generation Toyota Innova, it generates 149 PS (110 kW; 147 hp) at 3400 rpm, and 36.7 kg⋅m (360 N⋅m; 265 lb⋅ft) of torque at 1200-2600 rpm when mated to a 6-speed automatic transmission, depending on target market and emission specifications. With manual transmission, outputs are 149 PS (110 kW; 147 hp) and 34.9 kg⋅m (342 N⋅m; 252 lb⋅ft) [33]
