    How do you know the electrified car, like a Chevy Bolt, Nissan Leaf EV, or Model 3, will really deliver the range it advertises? Testing pure electric range is …

    In other words………they guess.

    Can you make these videos somewhere else ? That echo is terrible

    Electric vehicles could use smart heating and cooling elements around the vehicle and move on from the obsolete ways when you had just the central system because of the single engine.
    Just like led headlights that use many small diodes and can create the amazing matrix led intelligent headlights that adspt continuously as opposed to the obsolete single bulb systems from before with hid/halogen types, the same way heating the behicle can be achieved with efficient small sources that can be turned on or off, or with variable intensity based on the need.
    No more single zone, dual zone or 3 zones as existing aircon systems offer but a completely customizable area. Easy from the main control panel to select location of occupant and areas to be heated or cooled.
    For example you are alon in your vehicle and no need to warm the rest of it as onky you are inside. Turn in heat radiating elements around you. Not everywhere, just in the footwell and hands area, from a smart heated steering wheel.
    No more blowing heat through an inneficient obsolete central unit.

    Could you go into more detail about efficiency testing in a future video? It seems odd to me that the aerodynamics and weight seem to be left out of the test given the vehicle remains static on top of the dyno and yet those are often referred to as massive areas for improved efficiency. This test would lead me to believe (that as a theoretical case) an electrified hummer and a leaf (given the use of the same motors) would get very similar results in testing.

    but the wind is such a factor in fuel economy

    cooley did u get the email that people want u to do car reviews again ? i guess not

    Can you help. I got a petrol powered car, I drove it and got 20L/100km but the sticker said 9.5L/100Km.
    I drove done the highway and trip meter told me 900Km to empty, i turned the AC on and lost 300Km in range.
    In summer put my car on a dyno and had 20% less Kw than i did in Winter.
    Cooley please help me?!?
    Anything sound similar?

    Wait a minute, a Nissan LEAF 2019 Plus model has a 62kWh battery, not a 68kWh battery.

    We need to take the efficiency at power stations and electric grid into consideration for EVs. 60% efficiency at power stations. Times the efficiency of the grid. Times the efficiency of the charging and driving.

    Peter Epstein

    Interesting stuff and well presented, but I don't think you answered the question. Alphabet soup of range estimates presumably referred to EPA, NEDC, and WLTP, which are standards for estimating EV range in the US and Europe. You covered EPA range, but didn't say anything about the other two.

    What is that sticker on your Lenovo ThinkPad Laptop…..???just wondering…..

    Yess .. another awesome video from Cooley

    The range is never correct real mileage always differ and vary.

    jjj jjj

    Maybe a few things to be added for clarity.
    Battery size advertised and capacity available to the user are not the same thing and the gap will vary widely. Manufacturers should really get sued for not advertising usable capacity or just range, or regulators should step in.
    The MPGe is at the wall , factors in efficiency losses while charging.
    EVs also tend to me much more efficient than ICE in a city scenario than on the highway. If you take the cheapest Camry, its MPG is 34 combined, 29 city and 41 highway. The Model 3 Standard Range Plus is at 134 combined, 140 city and 128 highway. So Model 3 is 4.8 times more efficient in the city and 3.1 times more efficient on the highway. EVs do tend to be heavier and more streamlined and that should lead to the very opposite but ICE doesn't do well at all when it has to slow down, idle, stop, start.

    The AAA testing was unrealistic and you can go after ICE too, what's the efficiency in a hot summer day in stop and go traffic. Maybe you could test that, nobody is doing it so why not.


    I just use the seat warmers of my EV, which consume way less energy than turning heat on. And my EV allows for pre-conditioning of the cabin, so on my phone I can set the car to turn the AC on before I get in the car. Since the car's already plugged in, it draws electricity from the charger and range isn't affected.

    Just buy the BIGGEST battery you can afford. There is no substitute for more kWhs.


    Where do people think their battery power comes from? A hydrodam? Only difference when you drive an EV is the carbon emissions arent in your backyard, instead they are put in whoever lives by the electricity plant's backyard. 99% of our electricity comes from burning things. All you do by driving an EV is push the problem onto somebody else while sacrificing reliability and refuel time.

    The cold loss is not the same for all EV because some use newer tech like heat pump instead of resistance heater. I have heard it's best to use heat to get the car to 60ish F° for like your feet and use the seat heaters to keep your back and tush super warm.

    Juanito Caballes

    Cooley… you lost me in the first 2 mins…

    EV performs poorly in the cold isn't simply because heaters are less energy efficient than AC. I think it's got more to do with lithium-ion batteries' poor performance in cold weather, they can lose significant charge capacity below –10°C or 14 °F. At that point the chemical reactions in the batteries slow to a crawl. Don't mind your eMPG and heater, your car's not gonna charge from your home outlet!

    That's one of the reasons why I just don't see EVs, in their current state anyway, taking over the entire world.

    Cooley dropping knowledge!
    Excellent video, wow!

    But to be fair, how much % efficiency do gasoline engines drop in said extreme conditions?
    5,5% perhaps?

    EVs get all the press. Have you considered an episode looking at other alternative fuels like hydrogen?

    Tom Dixon

    Thank you for highlighting weather impact on range. As a Minnesota resident that just survived a February with many below 0°F mornings and a couple that were in the -30°F range I heard mumbling about the impact of cold weather on range. You showed the study that put some numbers to it. I think this is a big issue that they EV proponents should be more transparent about.


    That's a very interesting statistic about running the heat in your EV vs. running the air conditioning. We're all used to it being the opposite — the heat is basically free, since you're just using waste heat from the internal-combustion engine, and the A/C reduces your efficiency. We'll have to get used to wearing sweaters and running the heat at a lower temperature when we're all driving electric cars. It'll be like the late '70s all over again. Yay! (NOT!)

    Jason Harris

    I would be real interested in the long term cost of these vehicles via maintenance, etc. We normally snag a 3 year old car, but is the wise for these types of vehicles?!

    Also is there a long term recycle plan for when these cars are like 15-20 years old once they no longer can work? Batteries eventually die and that leaves cobalt, lithium etc to deal with to avoid environmental hazards.


    Excellent details, thank you!

    Reginald Sharma

    holy hell i got more confused lol

    Rick James

    Another electrifying video from. Im shocked, just how does he always do it!

    Buster Ecks

    There's always something to learn when Cooley speaks.

    Dave Taylor

    Would have thought the A/C would be a harsher pull than the heater

    Faruk Carushi

    Yep, you’re right.


    Think of a number double it; divide by 0.7; add 5% and the number you get is fudged.


    Tackling the full range of issues.

    As Alex says. "MPGe is stupid."


    People forget that the power plant that generated the energy is only maybe 35% efficient. Then there are losses in transporting the power to you and efficiency losses in converting to stored energy in the EV battery. When it's all said and done the amount of fossil fuel energy from a natural gas plant is very similar to just putting gas in your car….
