Toyota is developing a hydrogen-powered 5.0 V-8 engine.

It is based on the 5.0-liter V-8 engine used in the Lexus RC F luxury sport coupe, 

with modifications made to the injectors, cylinder heads, intake manifold, and more. 

The engine delivers up to 450 hp at 6,800 rpm and a maximum 540 N·m of torque of at 3,600 rpm. 

The engine is still in development, but Toyota plans to start testing it in vehicles in 2023. 

The company hopes to have the engine ready for production by 2025. 

Toyota is not the only automaker working on hydrogen-powered internal combustion engines.  

BMW, Hyundai, and General Motors are also developing hydrogen-powered V-8 engines.
