Toyota has absolutely nothing for the EV age having bet the house on hydrogen and failing that just ICE. Now they are scrambling and making promises on research when they have nothing remotely to suggest they can do what they are promising, not even a prototype.
Judging from the fact their EV was losing its wheels, there's also the problem of handling the extra torque, although I can't imagine that would take long to fix if they care at all.
Yes, and it takes no effort to make a rocket. Just put fuel in and ignite it. 100-year-old tech.
Making affordable EVs with a good range and fast charging is hard. Toyota' EVs are relatively expensive, and their batteries and drivetrain are mediocre.
Maybe we'll get in-car cold fusion first.
