With all the auto makers jumping on the hybrid bandwagon, I decided that Panthera would too. The EcoKat is based off the Panthera Panther's chassis, but sports an engine that can go 50 miles on electric before switching over to conventional fuels. This car can be recharged just by plugging it into any wall type outlet. It is capable of doing 125 MPH on electric and 135 on conventional fuels.
