Electric Versus Gas Cars – Comparative Video Shows Where The Future Lies

3 months ago by Mark Kane 26

Learn Engineering has released its second educational video about electric cars.

Following up its first segment “How does an Electric Car work ?”, it’s time for “Electric cars vs Petrol cars” video comparison.

Electric cars vs Petrol cars – Learn Engineering

Video concerns:

  • petrol engine and electric motor powertrain differences
  • refueling and charging
  • fuel tank and battery (energy density)
  • engine and electric motor/battery cooling
  • weight, centre of gravity, safety
  • power dynamics, transmission
  • economics

Electric cars vs Petrol cars

Electric cars or internal combustion engine cars—which is better? Electric cars were in their heyday back in 1900, but a sudden rise in petrol engine cars, accompanied by battery technology inefficiencies killed electric cars by 1920. However, with recent improvements in battery technology and power electronics, electric cars have made a strong comeback. We will compare these totally different technologies scientifically, and come to understand which is superior. Here we are using Tesla model S as electric car to compare with its petrol engine car counter part.

KYLE.DRIVES, who participated in making the Learn Engineering’s EV episodes, also released one more technical spot, focused on racing:

Electric vs. Combustion – Which Makes the Better Racecar?

Today we discuss a hot and controversial topic, electric vs petrol powered racecars, and which makes the ultimate racecars. This video was produced in conjunction with the Learn Engineering youtube channel.

    Both this and the previous video are quite slick, albeit overly Tesla-centered. But my main annoyance is the voice-over; the speaker uses EXACTLY THE SAME pitch modulation on EVERY SENTENCE. Mix it up a little; otherwise you sound like a robot.

    1. ffbj says:

      It is a robot.

      1. Loboc says:

        Our corporate training videos use the same computer-generated voice. Text-to-speech on steroids.

  2. SparkEV says:

    Lots of details are wrong, like comparing average gas car to Tesla. But they didn’t cover the most damning aspect of EV: needless waiting at DCFC due to those who get free charge!

    These days, it’s 100% guarantee that I’ll wait at DCFC: about 75% for i3, 20% for Leaf, 5% for Bolt that work for Lyft. Apparently, some Lyft who drive Bolt get free charging. But Bolt drivers have been gracious to disconnect at 80% or less. One i3 driver insisted on staying until 100%, second plug-in, making me wait almost an hour! Then I only charged 10 minutes to get home.

    1. SparkEV says:

      Forgot to include:

      Free charging SUCKS!!!

      1. (⌐■_■) Trollnonymous says:

        I’m pretty sure you’re talking about the locations where Nissan has the “No charge to charge” network.

        I’ve tried some free locations and it’s forever taken by either a LEAF or Plugin Hybrid.
        Then they just leave the car there the rest of the day……….JERKS!

      2. Sure, Free Charging Sucks, For You, and other Short Range EV’s not first in line at the Single Station DC Charging Spots!

        1. speculawyer says:

          He’s right though. Free charging creates irrational behavior. Free creates infinite demand and people abuse things.

          Tesla has already started to address problems by creating monetary penalties for cars that sit at Superchargers after they have completed charging.

          Economic incentives matter and should be carefully selected.

          1. SJC says:

            One of the more intelligent comments on here in a while.

        2. SparkEV says:

          It’s not just short range EV that’s facing the problem. When you go on a trip 100+ miles from home in your 200 miles range EV, you will wait. In effect, having DCFC becomes moot when you’re always waiting.

          Only need 10 minutes to get home from your 250 miles trip on your 240 miles EV? You could be waiting an hour! Decided to go off for a walk or lunch while waiting and the guy decided to unplug before you got back? Too bad you lost the place in line, could be another 30 minutes (or hour!) of waiting. This actually happened; fast food took over 20 minutes to order, and when I rushed back, another guy just started charging for 30 more minutes of waiting (it’s always 30 minutes!) Arrgghhh!

          Mathematically, it can be shown that subsampling can be representative of the larger set, and that’s exactly my experience. Even when I get 200+ miles range EV, I will need to use DCFC, and waiting for them due to free chargers is going to make me think twice about driving / owning EV.

            —————

            Don’t give up on EV…instead if your needing to make long range trips pick an EV that provides access to a convenient & reliable supercharging network. I love my Bolt but I don’t use it for long range trips for the very same charge hassle reasons you stated. For long range trips I only take my Model S and I’ve never had a charge problem with it…the Tesla Supercharger Network is night-vs-day compared to the current hodgepodge of the alternative.

    2. James P Heartney says:

      Given that the large majority of vehicle charging happens at home, and the fact that issues of charger availability are not inherent to the design of EV vehicles, I’d say SparkEV’s objection isn’t all that sensible.

      But do tell us what these other wrong details are.

      1. Bacardi says:

        One of the most heavily travel routes on the planet is SoCal to Las Vegas which depends where exactly in SoCal you’re going but that’s 300 miles and can include both 100F heat and sub-freezing temperature swings on the same drive…This is where “Tesla Loop” started and apparently has stopped offering it (rumored low bookings)…

        ——

        Imagine an alternative world that everyone has a gas pump in their garage (where a large majority of gas pumping happens) and for long range trips there is access to a limited number of what is mostly inconvenient & unreliable gas stations. Now imagine in that world a single car maker decides to build a vast network of convenient & reliable gas stations.

        1. That car maker is surely to be rewarded by lots of happy customers!

      3. SparkEV says:

        “But do tell us what these other wrong details are.”

        There are many, but one is comparing Tesla (induction motor EV) to average car and saying EVs are expensive. Tesla should be compared to luxury cars costing about $75K. While some EVs are expensive for what they deliver (eg. Leaf at MSRP), Tesla is not expensive.

    3. Prad Bitt says:

      There is no DCFC incentives to make a better network. GM, Nissan, BMW, etc. do not invest a dime in it. This is why we have to wait.

      And for the comparison, any average car has a century of improvements lying in his engine. They wisely chose to take the most sdvanced EV for subject. That’s fine with me.

      1. SparkEV says:

        Current waiting is not due to lack of DCFC. It’s mainly due to those who get free charging. If they charge at home, it’d cost them a dollar or much less since most EV I see already have way over 60%. But they still take full 30 minutes even if it’s only to add few more percent due to charge taper.

        i3 I was waiting is a perfect example. With charge taper and $0.20/min if he had to pay, he’d be paying more than 1 (one!) MPG gas car. But because it’s free to charge, he can play with his phone for an hour while wasting other people’s time. Meanwhile, I only needed 10 minutes but had to wait almost an hour.

        1. AlphaEdge says:

          Makes me to never want to get an EV, as I cannot charge at home.

          1. SparkEV says:

            If you must rely on DCFC, I would recommend against BEV if you live in an area where free charging is available. There’s just too much needless waiting. I tried an experiment of only using DCFC for a while, drove me nuts with ever increasing waiting events. It’s gotten lot worse recently.

        2. darth says:

          I get your frustration with waiting. But why would someone sit at the charger once they have enough to get home? Time is more valuable than the few pennies of free electrons you get at the end of a charge. People are strange.

    4. CDAVIS says:

      @SparkEV said: “These days, it’s 100% guarantee that I’ll wait at DCFC…”
      ——-

      Having access to a convenient & reliable supercharging network will increasingly be the X-factor that determines both the rate of overall EV adoption and which car makers win the largest EV market share.

      Access to a convenient & reliable supercharging network will become the other half of the car…its hard to sell half a car to anyone other than an EV enthusiast early-adopter.

    5. Rhaman 68 says:

      What are identifying is a lack of stations. Tesla has recognized this and the solution is simple: more sites; more chargers per site. This is similar to early car history and paved roads and parking. Once city governments and businesses wake up, parking structures should have outlets to charge all day in each slot. Shell in Europe plans chargers at all stations. Joe, who works all day, can park and charge all day without affecting others. Mary, going shopping, can do a 20 minute quick charge at DCFC regulated by fees. After 20 minutes the power goes off and fees double per minute. Seems punitive but people react to $$$. So the issue can be resolved but more units of all three types need to be installed and regulated. All cars do not charge at the same rate; not all drivers have the same needs. For sure, more stations are needed.

  3. Loboc says:

    DCFC will work itself out. An attendant would help tremendously in the near term.

    Shell may lead the way keeping the ‘gas up once a week’ paradigm alive. Once people discover the magic of having a full tank every morning, remote charging will become destination charging. Not too many people drive over 400mi/day. DCFC will be relagated to quick sessions to get enough juice for the destination or once-a-week fill-ups for folks without electricity.

    1. Loboc says:

      This DCFC conundrum will go away when people no longer own cars. Just call one up on your communicator. They will charge themselves when autonomy and self-charging are obiquitous.

  4. Bill Howland says:

    Agree with the other commenter who stated the video has plenty of errors.

    One big one ALWAYS made is efficiency comparisons – and the fact they INCORRECTLY stated the motor is the “Prime Mover”, thus indicating they don’t know what a Prime Mover is.

    Efficiency comparisons are meaningless between the two since the ICE can work on raw fuel, whereas the Electric car has to have this considerable processing work done elsewhere.

    I simply don’t know what the KWH input per mile is of a tesla from the wall plug – although supposedly this has greatly improved over the years, but I suspect it is still greatly temperature dependent.

    The price for fuel comparison is also cherry picked – there is NO WAY I could fuel any EV or PHEV in NYC for as cheaply as I could an equivalent ICE vehicle, without my own solar panels, that is. For them to say the operating cost of a Tesla is 1/3 certainly does NOT apply in downstate NY or in New England, where electric rates are universally confiscatory.
