That’s not how those work, they are just what is now a standard hybrid with a CVT gear box.I think a lot of the smaller Toyota hybrids work like this. The ICE never drives the wheels directly.
isnt that how the BMW I3 REX worked before it went pure Electric only?
Yes but they quickly realised hardly anyone actually used the REX once there was enough range in the car. It also wasn’t very reliable in the i3.
It also had a few issues in that the car needed to reserve 10% of the battery capacity to buffer the REX which is significant on a 100mile EV. It was possible to end up in a turtle mode if you went up a sustained incline while on REX because it didn’t actually generate that much electricity, in think on Rex it only returned 40mpg too. Regulations in some countries meant it couldn’t also have a bigger fuel tank than the electric range so even on the rex it’s range was comically low, circa 200 miles. I think that could be coded out though if you knew what you were doing.
Another example of a range extender is the new black cabs but I can’t see that lasting that long.
