I agree with this. I think if the i8 was around 1350kg it would be perfect. That's like a ~150kg advantage over say a 1M and still having similar power.

On a slightly different topic, (perhaps I'm being daft) but I don't see the benefit of these full electric models. As we know these cars will need to be charged up and where does electricity come from? It comes back to oil again. You are also right that these lithium batteries are going to stop holding a charge and will need to be charged more often. This again means using more electricity to charge them more often. It's an endless cycle of relying on oil.
