Tina Cordon@jackLondon What was your motivation for focussing on EVs in this toot? It seems to me that SUVs are a problem and that should be the focus, whether the SUVs are EV or ICE is not relevant to that. EVs don't have to be bigger, check out the Renault Twizzy and Microlino.
@jackLondon EVs don't have to be heavier than their equivalent. The Audi Q4 could be the same weight as the Audi A4 with a smaller battery and loss of range. I will back you if you argue for smaller batteries. The large majority of journeys we make don't need 300 miles of range. My street is badly potholed, my car is the first EV on the street, purchased last September. Is my car really to blame? Or is it poor investment by relevant authorities?
Howard Green@jackLondon @TinaCordon
do you have a source for your number? It seems very unlikely to me. Sure, batteries and electric motors are heavier than fuel tanks and gas motors: perhaps + 100-150kg. But there is also a lot less other stuff: gearboxes etc, and electric cars are mostly smaller than petrol.

jackLondonIt is 500kg for an Audi - I guess it depends on the size of the vehicles - so less for something like a Leaf
What is MTBF for EV batteries? There've been (rare) occasions when they caught fire standing still (eg a London bus last week) but if the full service life is considered, from minerals in the ground to recycled components being re-used what is the relative cost of EV vs ICE?
As I understand it still much better on fossil fuel consumption but overall?
@jackLondon @howardgreen Many EVs are now using LFP (Lithium Iron Phosphate) which don't catch fire. Lithium battery fires are rare now, as Lithium Ion batteries get replaced in new vehicles with LFP the MTBF will get longer. Battery life in new cars is already projected to be greater than car life meaning that many ex car batteries will be reused for storage when the original car is scrapped.
