Insulated Gate Bipolar Transistor. It’s essentially a cheaper way to handle high voltages.

Previous technology was commodity only up to around 200V.

Yes, there will be lots of new EVs joining the market in the next couple of years.

There are very few cars that will have 400 miles of range and I don’t believe there are any that will be cheaper than the Ioniq 6.

The problem is that even the most efficient power train that exists today would require around 100kWh of batteries to travel 400 miles. 100kWh of batteries are expensive and heavy, and a heavier battery lowers the efficiency of the vehicle. It’s not unlike the rocket equations, but less severe.

Yes, this makes sense. It makes more sense than NEVI, and would have been cheaper than NEVI.

Which is why it didn’t happen.
