Title: New Military Toy

Runs off multiple fuels and can charge anything electric while getting 100 miles between charges. 0-60 in 3.3 seconds, 70 mph top speed. Your tax dollars at work (play?).

I read a news report earlier this year that BRD had received a DARPA grant to develop a hybrid electric motorcycle, but that one in the video looks like their current prototype all-electric version to me.  The real issue with a hybrid motorcycle is packaging the IC engine (I think this one is supposed to be diesel), as well as the battery and electric motor.  That should be a real challenge and I am waiting to see how they manage that task.

The engine is multi-fuel, according to the video. It can burn petrol, diesel, JP8, aviation gas, kerosene, etc.

I guess packaging a serial hybrid may be easier than a parallel hybrid. You need a second motor/generator but can skip the transmission.

I'm pretty sure the bike is fully electric, and they are referring to the generator that charges it running any fuel.

The "military toy" is back in the news and it has a cute name:  SilentHawk.
