There's Tesla's with over 500,000km on a pack and they're still 90%+

Is that a general guide for all EV's? Someone the other day was asking about his 2013 Leaf that was 80 odd %. Less kwH battery size so probably double the cycles, but I doubt it had done massive mileage

No, it's only applicable to EVs that have active cooling of their pack, which excludes the Leaf, eGolf, Zoe and probably others I can't remember at the moment that are all passively cooled.

EVs such as those from Tesla, Hyundai, Kia, MG, Audi, Porsche and others are all actively cooled and should have a very long life.

Assuming what the state of health is can be a fatal purchasing mistake.

Never assume that because it does/does not have active cooling that the SoH will be this or that. Always check, and if the seller can't tell you either walk away, or extract it from the car diagnostics yourself.

I've been looking at BMW i3's and I was surprise to find that the SoH on many is compatible to Leafs of the same age and km's. Conventional wisdom says they should be better, but not so much.

I don't think anyone is saying don't do inspections - an engine in an ICE car should last the lifetime of the car too but if the vehicle wasn't looked after by the previous owners, ICE or EV, then it will have problems. Similarly, not all manufactures design things as well as their competitors. As an example, I'm not sure if BMW actively encourages or has a mechanism for limiting daily charges to 80% like a Tesla does to prevent unnecessary wear.

Sorry if this is a dumb question but we now often hear that battery packs will last the life of the vehicle. What is the life of a EV?

20 years? 300,000km+?

Thanks for that. I'm impressed.

Honest question - is it really that simple? Sure some have similar suppliers but really no differences in battery chemistry between these manufacturers and packs? Is there an example where it's exactly the same cell?

I think the next thing to impact the life is what the manufacture encourages owners to do in regards to charging. Tesla for example encourages people to charge no more than 90% daily and the cars will default to that - if you charge to max too many times it will actively warn you that this can damage it. Other manufactures (BMW) have no such warnings or defaults nor mechanisms to limit charge levels and will happily charge to 100% which will cause premature degradation.

Don't let Richard Hammond near this one!

Is the Rimac C_Two the fastest accelerating production car?

RimacAutomobili

"Straight line performance is by far not everything, but still quite important for a hypercar. We have designed the C_Two to impress with technology, usability, design, features, road manners and track performance. Lateral dynamics and driving fun was always super important for us. Today, we have focus on straight line performance but soon we’ll cover the other interesting aspects as well – like our new generation Torque Vectoring and drift mode."

Interesting that the Ford Escape PHEV seems to be an entry prize (one month’s use of). Ford removed it from their website and it is now buried deep in the EV section as “coming soon”. Originally it was supposed to to be last December, then this May.

I think that it is such an ugly looking car which is a pity. Some manufacturers are coming out with some really nice designs, but some are making their EVs ugly. Mazdas mx30 is also ugly imo compared to the cx30 it is based off, and impractical back doors.. It seems the main thing to consider when buying an EV is range vs cost, above much else

I really like the Ioniq 5 design. I think it’s quirky and fun.

You might like the design of the Kia EV6 better, it’s more of a traditional design. Both for exterior and the interior.
