G16E-GTS
editThe G16E-GTS is a turbocharged engine model with 10.5:1 compression ratio and D-4ST direct/port injection system with multi-oil jet piston cooling, large-diameter exhaust valves and a part-machined intake port. The turbo boost is set between 1.4 and 1.81 bar (20.3 and 26.3 psi). With the engine producing up to 224 kW (300 hp; 305 PS) (which comes out to 138.4 kW, 186 hp, 188 PS per litre), it makes the engine as one of the most powerful three-cylinder automobile engines ever produced.[2] The engine also has the highest specific output of any Toyota road car engine, exceeding the 95.6 kW (128 hp; 130 PS) per litre specific output from the 191 kW (256 hp; 260 PS) 2.0-litre 3S-GTE engine used in the ST246 Caldina GT-Four.[2]

Hydrogen version
editIn 2021, Toyota modified the G16E-GTS engine to run exclusively on hydrogen fuel. The modified engine ran in the 2021–2022 Super Taikyu series.[3] Toyota has tried to establish hydrogen as a zero-emission fuel alternative to petrol in motorsport and for daily use. In 2023, Toyota showcased its Corolla Cross H2 concept vehicle which used the hydrogen-fueled G16E-GTS engine.[4]
Others
editA de-stroked variation of the G16E-GTS engine with a displacement of 1.4 L (85.4 cu in), which is compatible with synthetic fuel, is used by the GR86 for the 2022 Super Taikyu series. The stroke was reduced from 89.7 to 77 mm (3.53 to 3.03 in).[5]
