Apparently the expected MSRP starts at over $70k and will extend well into the six-figure range. This is a luxury vehicle and one targeted at the commuting-but-compensating demographic.
400k of the 900k new F-150s sold in 2019 were bought by consumers the industry has termed "never-nevers." That is, they never tow and they never haul: they purchased a truck for its aesthetic or luxury value.
For this category of consumer, I suspect that conspicuous gas guzzling is actually more of a status symbol. If anything, I expect the electric F-150 will be best-selling as a commercial or fleet vehicle since that's where the added cost can be justified as a long-term investment.
