I dont know how much weight you can realistically keep off when you have to have a certain amount of batteries in it to provide a realistic amount of range.
It almost seems like an EV equipped car is roughly 400 lbs more than its ICE counterpart. |

It's not necessarily the range that's the problem with sports cars, it's the discharge rate. You can't pull as much current out of a small battery as a large battery. Which means you need a gigantic battery to put down the same acceleration numbers as a Tesla. And that's what sells apparently.

Maybe (probably?) I just haven't read into enough, but I haven't heard anything that would address the scarcity of the raw materials needed for batteries for anything approaching significant proportions of vehicles on the road. |

I wonder if the CEO at Porsche had a complete meltdown when he caught wind of the Tesla Plaid model. Maybe not, after all they got massive electrification press from the 918.
They have to make a better product and will continue to retain the knowhow to build track capable cars and sedan or SUV spin-offs at the upper end of the mass market. Interesting that Toyota CEO Akio Toyoda presented to a huge Japanese automotive trade committee, over which he presides informing the members that elimination of ICE production in Japan will result in loss of 5 million jobs by 2030. He went on to explain current and upcoming hybrid technologies have increasing environmental performance that will maintain prominence going forward. Light metals, ie lithium ion batteries entering the market are all recyclable. Not sure the percentage return on lithium when recycled but like steel, the more that gets manufactured then recycled, the bigger the available quantity of that commodity. Not sure.the limiting factor is lithium availability at least in the short term. Perhaps we will deplete lithium rather than oil from the planet at some point until another ion transfer element is used.

The problem is obvious.(climate change/CO2 emissions) The solutions are obvious (green power, EV cars) The In between is never thought or talked about because its never that easy because it eats into the narrative and may not make whatever green thing sound as green as it needs to be. (Raw Materials/scarcity/pollution, EV's arent as green as they seem, EV infrastructure sucks in most places around the world, charging times, disposal problems, costs, how to transition without completely effing up the economy, etc) |

1. Buyers are stupid. 0-60 times matter, driving characteristics, not so much.
2. Whiners insist they need more range, more range, more range, just to try to entrench on avoiding change. But there is also some truth, too little can really be a trouble. So big batteries are a thing. Somewhere along the way we'll find a decent place where range works. 3. With the weight low on the chassis and the torque plentiful, weight is not necessarily the problem. It doesn't matter if we manage micro-fusion reactors in a few years and batteries aren't a thing. Electric probably IS here to stay, and for performance nerds that really should be a good thing. Right now, batteries are our best answer. Use 'em, keep searching for better. I expect a great handling, fun to drive car from Porsche. Some day we'll see more affordable options... But likely not as cheap as we're currently happy with. TCO might be similar though, just more up front. Also, Lotus IS developing new platforms. Some interesting stuff.

Between lacking infrastructure and economic ability, BEVs would be a tough sell (to say the least). A hybrid would at least be fine with just rudimentary infrastructure (you can still gas it up if you run out of charge; just strap some jerry cans to the roof). |

I remember an EV swap where the person used a Nissan Leaf battery with a Tesla motor and said the Nissan battery made the car faster, but this was a purpose built drag car, so range was not a concern. The pouch design technically is lighter and more energy dense and has a higher C rating for discharging.
