Thinking about it some more, maybe in a mass produced ICE AWD can indeed be a cheaper add-on. Something like a Subaru that does AWD for all cars. I was thinking more of the direct Tesla competitors that tend to charge quite a bit for AWD as an extra. But it's hard to compare from the outside as adding AWD to a car is often associated with different trim levels too. Someone like Sandy Munro that does detailed costing would be able to answer this definitively for a few models. But it will most likely depend on the actual implementation to see what ends up cheaper. According to Munro Tesla has a big advantage in the cost, weight and performance of the motors right now compared to other EVs so that might be enough to tip the scale. I'd love actual data though.
