The Volta uses a simular 3.3 liter V6 hybrid system that will be used in the upcoming Lexus RX400h. It is said to produce somewhere in the neighborhood of 400hp and will go 0-60 in about 4 seconds with a top speed exceeding 160 mph. The amazing part is that it will do this while still achieving about 30 mpg. It is 169 inches long and 79 inches wide, which actually enough to hold three people across.
Here is the link where I got the info.
