Ford reveals all-electric ‘Mustang Lithium’ with 900hp at SEMA

Yesterday we were treated to a spy shot of some sort of electric Mustang under wraps at SEMA. At the time, we could tell it was at least a plug-in, but thought it must have been a plug-in hybrid.
It looks like we were wrong, as today that car has been revealed as an all-electric, high-performance Mustang.
