  • I see I've triggered a few PHEV owners in this thread in the last 24 hours.

    There are a few news reports and studies, including this US one from the end of last year that suggest two things:

    1. People aren't charging their PHEV at all or as much as they should be to come anywhere close to the claimed emissions figures
    2. Fuel consumption (and therefore emissions) are much higher in real life for PHEV than the stated emission per mile anyway

    It's also worth noting that calculations for emissions for fuel consumed do not consider environmental cost of extracting, transporting, refining, transporting again, storage and delivery of fuel over electricity which, even when created through the burning of fossil fuels, is far better for the environment.

    Sure there are people on this thread who own super edge case, no longer for sale, hybrid oddities or who charge every day but there are also loads of people who bought a 330e or an X5 hybrid on their company scheme because of the massively lower company car tax who haven't charged them once in their life.

    Even if they do, the range claims are clearly false, with that Guardian article that started this discussed yesterday showing the BMW tested as spewing out 3x more carbon on average than claimed.

    Finally, the vast majority of hybrids are also large vehicles. Toyota make a few small ones but most are large SUVs which only exacerbates the problem.

    Con. Job.

    They did when I used to do LCA. You have two issues with current large, longer-range EV vehicles:
    1) there's a circa 100kWh lithium battery onboard and this weighs in the order of 700kg. This is enormously energy-intensive and polluting to produce, compared to anything previously made by the car industry. It's an enormous one-off environmental impact that hugely eats into any benefits of electricity vs fuel during the use phase.
    2) most bigger EVs do closer to 2.5 miles per kWh in real life than their stated mileage and that's not very efficient. That means it's very difficult to offset/recoup/justify that impact from the battery manufacture during the use phase.

    It's a completely different story with small EVs. 25-30kWh batteries are 25-30% the environmental impact and the car travels almost twice as far per kWh.

    Ok Soul. Yawn.

  • I mean I’m sitting on an average of 267 wH pm for the Model Y over 13,000 miles in the last year so that’s definitely not the case for all large EVs. It’s more efficient that our Zoe which is sitting at roughly 315wH pm.

    There is absolutely no way that a Mitsubishi Outlander PHEV is more efficient than a Tesla Model 3 or Model Y or even a BMW iX for that matter over its lifetime.

    Sounds like I did get you to bite a little on your funny car 😬
