I expect at least 10,000 hours out of an electric car, and maybe up to 30,000. They should be more reliable than an ICE.

What wears out first in an electric car is the battery, I would assume.

  Their failure mode is continuous though and the bigger the battery, the smaller the absolute impact of wear. What people fail to grasp is that yes right now batteries may only go up to 200 miles for an affordable EV but if EVs had the same range as ICE cars then their useful lifespan would be even longer than it is right now.

  I would probably assume it would be ball joints, bushings, bearings, AC components, seals, body corrosion, paint, or something similar. An ICE vehicle with 300,000 miles on it is usually only still on the road because the motor works. Everything else is usually completely shot

  It is unlikely that the battery would wear out faster than other key components in an EV or hybrid. There is plenty of real world data from tesla model S owners showing that the batteries easily last more than 200k miles, which is about how long cars in the US last before getting scrapped. https://maartensteinbuch.com/2015/01/24/tesla-model-s-battery-degradation-data/ https://maartensteinbuch.com/2015/01/24/tesla-model-s-batter... The same is more or less true for Priuses, their batteries last around 150-200k miles.

    What I take from that graph is that there is not enough data to say what happens beyond 50k miles.

      Really? The data in the second graph appears to corroborate with the testing graphs that Tesla themselves have released, which is what the first graph is.

Cars are commonly engineered to be driven for 8000h which corresponds to 15 years lifetime. Different story for commercial vehicles of course. Fun fact: cars are commonly designed to be operated for 8h in reverse gear over lifetime. Another fun fact: Electric drills are used for an _average_ of 8 minutes over their lifetime.

  > Electric drills are used for an _average_ of 8 minutes over their lifetime. I did see that somewhere, and I think it was in the context that every home has an electric drill, but most might only get used for 1 or 2 projects a year. You would hope though that this might be only a design guide for one of those $30 stocking stuffers. I'm an owner builder and I am pretty sure my drills and impact drivers have racked up many tens of hours.

    Also "used" in this context clearly just means "spinning". I did a modest project the other day involving my electric drill. It involved 20 holes, each hole drilled in two steps (pilot with a jig in place, full depth with the jig removed), for 40 spins. I'll guess that each spin took about 3 seconds (because that makes the math easy), so 2 minutes total. I couldn't exactly share the drill with a neighbor in the approximate hour that I spent measuring and repositioning the jig between uses. In the context of duty cycle lifetime, maybe 8 minutes isn't that low -- but I am definitely using it for more than 8 minutes.

      Using a hole saw and cutting into metal, I'm pretty sure I could spend 8 minutes per hole. Of course I prefer to use the drill press for this, but some projects can't fit and must be done with a hand drill. Then there's the grit wheel or flap disc, which might have me axially loading the drill for 30 minutes at a time (such as for stripping paint or sanding rust off an iron engine block). I think they must be including a lot of people who buy or receive a drill as a gift and never use it at all, to get to 8 minutes average. I do find it believable that the cheaper ones might have a design life of 8 minutes, but that's a sad state of affairs.
