GV27:

The EV6 is a lovely looking car but the steering wheel seems a bit parts bin-ish.

Hopefully there is something a bit more befitting the GT's range-topping status in a later refresh.

maybe coz it's a Kia. at least the outside looks good.

The rest of the interior is great though. The steering wheel lets it down.

The Stinger GT wheel is much nicer, so whatever design statement the EV6 is making by having that wheel with such a polished interior is missing the mark.

KiwiME:

I'm not clear on why the heat pump is not used to heat the battery. I don't think the Model 3 does this either.

The model 3 uses the motors to produce heat for the battery primarily, this can use over 12kw, way more than the heatpump could produce

I got a little bit excited when I read this headline on a Google alert:

Tesla has launched the Model Y in the United Kingdom and several other right-hand-drive markets...

Given there aren't too many other right-hand drive markets, especially ones where the Y's release is supposed to be coming soon, I thought MAYBE that could include NZ?

So I dug out the article and read further:

Tim Findlay, Tesla’s market leader for the UK and Ireland, announced that deliveries of the Model Y have started in the UK, Wales, Scotland, and Northern Ireland

https://electrek.co/2022/02/22/tesla-launches-model-y-uk-other-right-hand-drive-markets/

What a let-down, thanks to some writer's inability to understand the difference between England and the United Kingdom!

can someone explain permanent magnet and induction motors?

i have no idea of the significance.

is one better than the other? why some cars have both?

LDV is soon launching NZ's first EV ute.

The T60. It's RWD and has a decent battery pack...over 80kWh. This will scratch a lot of itches. They say they are trying to keep the price under $80k to qualify for the incentive. Spending $0 on fuel from day one.

And Stuff has a write-up on the ute based on a test-drive of the test vehicle they have in NZ:

Permanent magnet just means that some of the magnets (either the rotor or the stator) are not electric coils. Permanent magnet motors are more commonly DC motors but don't have to be (could be synchronous AC). Induction motors are AC motors where both sets of magnets are electric coils.

In a synchronous motor, both sets of coils are directly driven by electricity. Because the fields are both driven together, they are synchronised, and the rotation of the motor is also synchronised to the frequency of the AC. But a synchronous motor where the rotor is driven implies some sort of mechanical arrangement where the current can be applied to a rotating part, which means a sliding contact, which creates wear, some sparks etc.

In an induction motor then rotor windings are simply shorted together. The magnetic field is induced (hence the name) by making the rotor be the secondary winding of a transformer. But if the rotor turns at the same speed as the stator field then the stator field is stationary from the rotor's point of view. Induction only works in a changing magnetic field, so a "stationary" field means the rotor doesn't generate any field in response. For this reason the rotor always turns just a little more slowly than the stator field frequency (this is called slip), usually something like 5% slower.

The main advantage of permanent magnets is that they can be lighter and more efficient for a given power rating which is obviously important in the context of an EV. But they're also more expensive so you are less likely to find them in, say, your washing machine or fridge where a cheaper AC induction motor is perfectly OK.

And that exhausts everything I remember from the Power & Machines courses in my Electrical Engineering degree from 25 years ago. Thank you Dr. Mahmood Nagrial!

ok thanks doesn't sound that one is better/last longer than the other for the average EV owner

Saw this last night. US Kia Dealers selling new EV6's with large markups.

From what I can tell it is certainly not limited to Kia dealers in the US. Most brands in the US that use the dealership model are suffering from the dealerships charging customers desperate for a vehicle way over the RRP. They better make hay while the sun shines because rorted customers are unlikely to return.

The direct sales model from the likes of Tesla provide obvious benefits to the consumer in this environment.

The usual reasons. Size of the market, distance, taxes, number of people in the food chain punching the ticket.
