Batman:

probably the ultra wide ultra low profile tyres all EVs need to corner in the dry. was it a performance Y?

though i do suspect that stability control was turned off

No. those wheels mean a long range model Y. Theres also no ability to switch stability control off on that car.

SC only works if you have grip

Batman:

was just comparing specs of the Ioniq 5 vs EV6 and both cars don't give you a heatpump unless you buy the most expensive model.

who pays $120k for a Kia / Hyundai

Does that mean no aircon unless you buy an option? Or just less efficient heating? I like the look of an EV6 but haven't owned a car without aircon since 1999 and don't intend to start now

They have air con, just not the extra bits that make it a heat pump so will use resistive heating.

In NZ climate its a bit of drawback as our heating requirements usually fall well within the good range for heatpumps

My 3 doesnt have one though and it does ok..

Isn’t the heat pump tied into the battery thermal management as well? Using the thermal energy from the drivetrain to assist warming the cabin. More efficient than total loss radiator systems.

I do agree with @Obraik some things should be included as basic equipment. Not as “option packs” which European manufacturers seem to favour, or only in higher spec levels (Japanese and Korean). I can understand manufacturers not offering a bespoke build system (a la Japan DM) in NZ as we are too small a market, but safety and efficiency systems shouldn’t be upsells. Particularly if that carries the vehicle outside the rebate price bracket.

i won't assume that's what every car does. it depends if the engineers had a good sleep the night before designing them.

and afaik they're not even option packs you i think you have to buy the top of the range to get it.

Margins are tight in the auto world esp on EVs (outside of tesla..), upselling to higher end cars and packages is a solid bump to the bottom line.

They likely have whole buildings full of people working out what the best way of structuring model lineups and equipment packages

I’m not quite sure what this collection of words means means. Some punctuation would help.

If you mean that the vehicles from the Korean manufacturers require you to get a specific model to gain some of the features (ie no such thing as option packs), then I agree.

The option packs are something European manufacturers seem to do. They reduce the base price but in reality most customers will add them. A case in point is Polestar*. The Polestar 2 has a whole lot of driver assistance and safety features in its ‘Pilot Pack’ and a bunch of comfort features, including a heat pump, in its ‘Plus Pack’. The majority of the P2s sold/ordered in NZ have been Std range + pilot + plus. The next most popular is the Long Range (which includes the Pilot Pack just to confuse things). Both those specs just sneak in under the $80K (via a launch special).

*I know Polestar is Chinese owned and manufactured, but it is still an offshoot of Volvo I believe.

Porsche make hot cars but this is ridiculous.

Joao Mendes Cabecas, a captain of the nearby port of Hortas, told Reuters that lithium-ion batteries in the electric cars on the Felicity Ace caught fire, but it was unclear whether that is what started the blaze.

Sure they caught fire, like well, everything, on the ship.

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.

The subsidy for EVs under $80k certainly put offered configurations in a spin and it seems that heat pumps were an easy target. My base Kona EV ('18) has this and it's wonderful in our mild climate. The power draw is similar to AC, averaging around 0.4 kW. The PTC (which is still there as a backup) is 5.5kW approx full tilt but of course will be modulated.

The Kona has both a condenser and evaporator in the cabin airflow. The Model 3 heats uses intermediate coolant via a heat exchanger to a heater core ... if I'm not mistaken.

The "AC" system is used to cool the Kona battery over about 40°C but it can also use "passive" cooling via coolant and a radiator for less severe conditions.

For battery heating the Kona battery only a separate 2.2kW PTC heater is used and that can warm it at 1°C per minute to improve DC charging speed when under 15°C. During driving that same heater will kick-in at under -5°C to improve performance.

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.

I believe the Peugeot e208/2008 have heat pumps as does the Mini. Yes, on Hyundai/Kia it's only on higher spec models. I would not buy an EV without a heat pump but I would buy one with a battery slightly smaller than 64kWh. Range anxiety was only a factor before I bought the EV, much less so now.

I must mention that the Ioniq 5 Hyundai models have two coolant loops, one with low-conductivity coolant for the battery that has a short change interval and is very pricey. The Kia EV6 only has one, despite being of the same base design. Konas have one coolant loop with the fancy coolant only in later cars, past 2019. It seems to be a knee-jerk reaction to the battery issues as there is lab evidence that coolant can initiate a fire after a severe crash where it floods the battery pack cavity. No other EVs use this sort of coolant but it should be a consideration for anyone considering the Ioniq 5.
