Seriously TMC, don't turn Lexus into an EV only brand, unless you really don't mind sending your luxury brand straight to the automotive graveyard.
You could build the fastest and most powerful EV in the world, but even then hardly anyone would give a crap about it and it will end up sitting at the dealership collecting dust and taking up space. Most performance car buyers still want ICE cars, whether it's hot hatchbacks or hypercars, and now even many non-car people have finally found out the shortcomings of EVs, with some finding it out the hard way, e.g. houses getting burnt down by an EV, amazingly high insurance costs, pathetic used market value, etc. etc.
