20. Electric cars actually have some advantages over cars with internal combustion engines.

Electric motors have a huge amount of torque for their weight, which means that if you goose the accelerator, your electric car's gonna take off like a rocket! Electric motors also provide lots of torque over a wiiiiiiide range of RPMs, from zero to very high speeds, so electric cars don't need transmissions - there's a big weight-saver.

Of course, there's the disadvantages - battery technology is still the bottleneck, and range suffers, especially if you're punching the throttle and hot-rodding the car, though recent years have seen enough advances to make electric cars viable. The batteries are still quite heavy, though the Tesla S mitigates that by putting them in a pan under the floor - still heavy, but the battery case adds to the rigidity of the car's frame, moves the center of gravity low, so the car actually performs decently well.

Yeah, that's the one. I was mistaken. The image I had in my mind looked like a Fiat. HopeHoops Aug 2012 #26

That's a rather silly comparo. Especially as the V8 powered Atom trounces those other cars too. EOTE Jul 2012 #21
