There is only a pair of driven wheels in the drivetrain mock-up. It is either front wheel drive (yuck!), or rear wheel drive (yay!).... unfortunately this example will likely be Front wheel drive.

I like the idea of hydrogen as opposed to batteries. I just need to know what the 'feel' will be like... will it be as heavy and cumbersome as a battery electric car, or will it be agile and nimble like a lightweight ice car? If it's BMW, the sporty models need to be rear wheel drive.
