The hydrogen hybrid drivetrain is currently under development and it will most likely be used in the upcoming generation of front-wheel drive BMWs and perhaps even seen in the next generation Mini.
The idea behind the system is rather simple. It combines a traditional front-wheel drive setup with a hydrogen fuel cell, electricity-storing super-capacitors and an electrically driven rear axle.
BMW tested a fleet of 7 Series hydrogen vehicles some time ago but the system seen here appears to be an evolution of that technology.
