Nikkei is reporting BMW will soon be using Toyota's fuel-cell vehicle technology.
A final agreement between the two parties is very close and would allow BMW to use Toyota's drivetrain and hydrogen storage tech. The German company will develop a prototype within the next three years and is expected to launch a production model by 2020.
Recently, BMW and Toyota have been expanding their R&D connections as back in December 2011 they agreed to work together on green car tech, including co-developing lithium-ion batteries. As part of this collaboration, BMW would provide Toyota with diesel engines for the cars sold in Europe. In June 2012, Toyota and BMW agreed to cooperate in the development of fuel cells for a future sports car.
Nikkei adds various automakers such as GM, Daimler, Honda, Nissan and Hyundai are all working on fuel-cell cars.
