This isn’t going to shave much weight off of EV’s. Typically the engine weight is only 2-5% of the total weight. But it may have a much larger effect on battery efficiency and range.

Internal combustion engine cars are now in their decline phase. We won’t see any more technological innovation from them. From now on all the tech innovation is going to be in EVs, which will keep getting better and better than the old gas cars.
