BYD e6
I drove the e6 a few years ago and it was a step above a prototype. I'm sure the ones sold to Uber will be a much better improvement. It was an impressive car, at least in terms of specs. I forgot exactly how much kWh it had, but it was in the vicinity of high-80s. The car boasted 180 ~ 220 miles then, although we figured a more conservative 140~. It had a "sports" mode and a regular mode. It only only fun to drive in sports mode. But boy was it HEAVY! It had fans constantly spinning to keep the pack cooled. Can't say I felt super safe in it. A lot of clicks and clunks. Definitely an interesting experience, considering all we've heard about Chinese cars.
It used Li-ion batteries, so it makes sense BYD would have switched to Fe. I think this is Buffet's and BYD's big "game changer" story.
