So the price delta between 300 mile and 500 mile is $30,000.

2 kWhr per mile means the 300 mile is a 600 kWhr battery and the 500 mile is 1000 kWhr.

400 kWhr's for $30k means they are expecting $75 per kWhr battery costs. Last year they said it was under $190 per kWhr.

I am very skeptical they can meet that target, $75 would be pretty revolutionary in such a short time.

I'm expecting Tesla to make truck drivers pay for faster charging. this might be a way to reduce initial costs.

Tesla already said that megacharging (supercharing for trucks) will be 7 cents per kWh in all states, so that truck drivers have predictable costs (unlink Diesel, which can vary greatly).

Yeah I did the same calculation. Apparently below $100/kWhr is the 'tipping' point so $75 ought to get things rocking.

I read "semi electric truck", and wondered what "semi electric" means. Hybrid?

But reading the article, it becomes more clear that it's about the Tesla Semi, which is an electric truck. Confusing headline.

You might not be American. I had the same confusion when I called 911 to report an accident driving across the US and they asked me if the truck was a "semi".

But even if it's a type of truck, calling it a semi electric truck is weird. I would have expected it to be an electric semi truck, or something.

I’ve been trying to work out the relevance of you driving a Porsche and the weird phasing (you called your car?). Ironic confusion given the discussion on regional lanagaue variations.

Maybe it should have been an "electric semi truck"
