Big fat battery. Teslas are pig heavy; there is no way around it. Having said that, the center of gravity is really low so the handling is planted; it sticks! Are they that much heavier? No, I don't think so.It is very nice looking all in black the way I viewed it. Do they really weigh a lot more than ICE or is that some hype?
Go take a test drive.
