The 2017 Bolt claims a 238 mile range a lot like Lenovo claims my laptop has 10 hour battery life. I'm lucky to get 4 hours with normal use, but if I turn off my music, disable wifi, turn the screen brightness all the way down, don't use Chrome, etc. I'll probably get at least double.

    While foggy Monterey weather may pass for summer in many parts of Europe and Canada, they weren't in Europe or Canada, they were in Monterey. Though I'm not sure what "cool looking" weather looks like in a photo of an automobile with no living creature around. If you don't believe they saw fog, the video included with the article shows the fog when he's crossing Bixby Bridge, about 30 minutes south of Monterey - skip to the 30 second mark.

      Just saying that the mileage is not going to be close to what they are advertising in a cold climate.

        Tesla owners report about a 20% drop in range in cold weather. The Detroit Free Press got about half way through a test in freezing (11F/-11C) temperatures with the Bolt before getting rear ended, but they were on track to go 200 miles. Whether the mileage is 240, 200, or 180, that's still more than enough for most people to commute multiple days. Around 70% of US drivers have a one way commute of 15 miles or less. http://www.freep.com/story/money/cars/mark-phelan/2016/12/17/chevrolet-bolt-fender-bender-accident/95481484/ http://www.freep.com/story/money/cars/mark-phelan/2016/12/17...

        Why aren't Bolt batteries nearly as affected as Tesla batteries? It seems like they would be bound by the same physics laws?
        Johnny555 10y ago
        I think they are equally affected -- 200 miles is about 20% less than the good weather range of 238 miles.

  A friend who owns a Volt can get from SF to only Mountain View, and then it switches over to using gasoline.
  - Johnny555 10y ago
    Other than the fact that "Volt" rhymes with "Bolt", why is the all electric range of a Chevy Volt relevant to the Bolt?
  - cobookman 10y ago
    Volts electric range isn't for long road trips. That's why it has an ice as a backup generator. It's an electric car for today. Great car btw. After all incentives and dealer rebates you can get one for ~21k. Has 50 miles of electric range and it's backup generator gets 42 mpg. And unlike the i3 rex it can travel at full speed on gas.

      yeah it was the first sensible electric car that wasn't built for wealthy people or green idealists and I seriously considered getting one, but in the end they never reached Italy

Are you sure? A typical phone battery is 5Wh. Let's say it is 5V times 1A times 1h (most of the time the phone does not drain 1A), that's a generous 5W of consumption for a phone. A Volt's battery is less than 20 kWh, and it has to last several hours, so it probably consumes around 5 kW. Now take the phone's 5W a base; Even adding 10W to charge two devices, 10W for the bigger display, and 20W for the speakers, I doubt that electronics and in-car entertainment consumes more than 2-3% (150W) of the overall energy needed by the car. Air conditioning is much more expensive, and the effect on ICE fuel usage is there but practically impossible to measure.

  To be clear, I wasn't talking about music, wifi, brightness on the car, I was talking about it on my Thinkpad. I'd only use units of time (hours) to measure a laptop's battery life, I wouldn't use time as a unit for measuring a car's battery capacity. Taking car rides in my buddy's Volt will only get us from SF to Mountain View, and then it will switch to using gasoline. How you accelerate/brake/etc, city vs. highway driving, and following distance from other cars ("drafting") can really affect the range...

  I think you meant bolt not volt.
  - bonzini 10y ago
    I reported numbers for the Volt, but the Volt's battery definitely doesn't last several hours, so the effect is even more negligible.
