    • hideous front end and rear not better
    • too many buttons and knobs in cabin
    Less is more which is why I have no interest in this kludge. I did not see an EPA rating but given the front, cabin, and rear, is unlikely to appeal to me.

    Well two of three, missing 'good':


    Driving off the lot, I would be playing.

    no one is worried about gm competition, nor should they. but it certainly creates clickbait

    How much does A/C affect your Prime's EV range? Not much, right? How about heat? A lot more, right? There is your answer.
     
  10. 15-20% reduction, more if stuck in traffic.

    That is significant.

    25-30% reduction.

    Both are significant, which is exactly why I said what I said.

    Your Prime has a tiny battery. A hypothetical BEV version would use the same amount of energy to heat or cool that space, but take it from a much larger battery, leading to a smaller percentage loss. 5 miles of range loss is big when you start with 25, but not when it is well over a hundred.

    We don't know what equipment the Blazer will have. It will take more energy to condition the cabin than the Prius simply because it is bigger, but the shortest range trim will have one over 200 miles. Give the rear seats heating, maybe use radiant like the bZ4X, and the need to completely heat the cabin can be less than in the Prius.

    If it uses a heat pump to cool/heat wouldn't the car use the same amount of energy for either? I've heard, but don't know for myself, that car heat pumps are an efficient way to control temperature with minimal energy consumption

    Heat pumps included in GM EVs could give them a real-world range advantage (greencarreports.com)

    "GM confirmed Monday that it plans to include heat-pump technology in all of its current and upcoming Ultium-platform electric vehicles. "

    "The system is based around an automotive-grade heat pump that captures and recoups that waste heat. Like the systems other automakers like Tesla use (or Toyota, with the illustration below), the one in GM EVs employs a compressor-and-evaporator component system and a specially chosen refrigerant that undergoes a phase change. A physical reaction pays off in the release of energy as it goes from gas to liquid—to in effect amplify whatever energy it can scavenge along the way."

    "A heat pump can also assist in other ways. For example, it can take the energy generated from the phase change of its liquid refrigerant to help precondition a battery in the extreme cold or even power some low-level functions of the vehicle. The total benefit to vehicle range can be as much as 10% and, friends, that's not exactly chicken feed."

    Probably too many buttons and knobs. :p

    Heat pumps are more efficient than resistant heaters because they move heat around instead of making it. How efficiently they do that depends on how much heat is around to gather up. Less heat takes more heat. So heating generally takes more energy than cooling for a heat pump.

    Consider this, a heat pump has a minimum temperate it can heat pump. Get colder than that, and it there simply isn't enough heat outside for it to transfer inside. When it's extremely hot outside, an air conditioner can still move heat from inside to outside. It might struggle to keep the inside comfortable, but that's because there is more heat than it can move in a given time.

    And a golf cart store opened up along my commute.

    This car might be smaller than a Spark. It doesn't have the same level of safety features, and likely lacks some of what is now standard features here.

    As a NEV, its max speed would need to be throttled to a max of 35mph to be sold in the US.

    2023 Chevy Bolt Is Now The Nation’s Cheapest EV at $26,595 | PriusChat

    According to this link in USA
    2022 U.S. Auto Manufacturer Sales Figures | GCBC (goodcarbadcar.net)

    GM cars sold for 1st half of 2022 = 1,089,853
    Tesla cars sold for 1st half of 2022 = 282,071

    Doesn't seem like much of a fight.

    Easy to see GM making huge strides in EV market once they get their product aligned with their consumers preferences like they are now doing in China.

    I wish GM well and hope they bring extreme competition and price pressure to the EV market.

    If I understand correctly both Ford and Chevy are currently selling all electric trucks - where are Teslas electric trucks?

    that's a lot of optimism for gm, i don't feel the same way. they've dropped the ball so many times, it is hard to convince myself that they will finally get it right.

    can they build and sell gassers, absolutely, although they've tripped up on those as well in the past.

    tesla has a proven product, i don't have to be optimistic. can things change? yes. will they?

    Chevy Bolt charges at a maximum of 50 kW which makes cross country trips impractical. My 2019 Tesla Model 3 has a peak rate over 170 kW. The Supercharger network is dense enough most charging stops are less than 15 minutes.

    it's a nice little runabout. smaller than prius, it doesn't work for many americans
