By the time 2022 rolls around we'll have seen a dramatic increase in public charging stations. That you can bet on. Regardless, the conventional S-class sedan will have a PHEV version as well. They've actually already sold a PHEV S-class (S550e) here in the past, but was sold in very small quantities due to limited range.Given the only coherent fast charge network in North America is Tesla's I don't see how that's gonna work. PHEV is the way forward until probably 2030.
