    I used to like hybrids, and obviously series hybrids are the coolest kind of hybrids, but now that I’m driving a budget EV, I honestly don’t see the point anymore. Just get the EV and skip the awkward half-way step that inherits the most expensive and complicated parts from both designs.

    Seeing a sleek modern car pull away whisper quiet and then start the ICE 3 seconds later with a stutter and a puff of water vapor from underneath is the most schizophrenic sight, it somehow feels more dated than actual ICE cars.

    Unless you live in bumfuck nowhere with expensive electricity, zero solar power and a daily 5 hour commute, an EV will likely work just fine for you.

      Also city dwellers with street parking and it’s hard charge, so a pure EV is a bad fit.

      Hybrids with their good mileage although complex are a good fit for those.

        Driving hybrid still burns gas, generating CO2 which is destroying the world. Why would anyone pick it when EVs are available is beyond me.

          It's not that simple. A pure EV needs ~10x as much battery as a PHEV. So for the same amount of batteries produced, you could make 10x as many vehicles PHEVs as EVs. Not all vehicles can be EVs due to practical issues.

          Which results in more total electric miles driven replacing gas? I don't know, but "gas is destroying the world" is a brain short circuit.

            What's making you short circuit? Gas is destroying the world.

          EVs are more expensive. Hope that helps.

          Yes, EV's solve one of the many negative impacts of cars. It's not some magic bullet.

          They still depend on minerals that require destructive mining from equipment that runs on fossil fuels, still use rubber tires, still has tons of plastics that are made with petroleum, still dependent on a power grid mainly sustained by fossil fuels...

          We should be thinking bigger than this, even. Walk, ride a bike, or take public transit whenever possible. If it's not possible, try to move somewhere where it is.

          We must be willing to be slightly inconvenienced for the greater good instead of arguing about which type of car to drive. People don't want to have that conversation, though.

            Of course they don't. That's a great argument for changing structural incentives, but not for convincing people who are talking about what car to buy.

          Hybrids have much more efficient ICE motors, which generate less CO2 than the motors of traditional cars. The amount of CO2 is further reduced by energy recovery.

          TFA links another page where it is explained how the ICE motors used in Nissan hybrids have surpassed 50% efficiency, which is an efficiency that in the past was reached only in huge 2-stroke Diesel engines for ships.

          50% is already not much lower than the efficiency of the gas turbines used in electricity generation plants, but the power plants with combined cycle (gas turbines + steam turbines) may reach over 65% efficiency and the power plants with Combined Heat and Power may reach over 80% total efficiency.

          Battery EVs may take advantage of continuous improvements in the energy generation infrastructure, but for now they are still not usable everywhere, so hybrids are still preferable to cars with pure ICEs.

            The Carnot cycle makes it impossible for that to be true unless they're ignoring something.
