I'm not sure which EVs can do this, but it seems a fair few.

So for some light-hearted Friday debate, which is better... arriving at a cool car on a scorching hot day, or a warm, defrosted car on a freezing cold day?


Overall, I go for the warm car on a cold day, if only because of the added bonus of demisting/frosting the glass.

Zoe can do both and I would agree with you that the option of having the car warmed up and de-misted is a great bonus in winter. Not had the Zoe through a winter yet so that joy is to come! I believe the air con on the Zoe is great for cooling although I have it permanently in Eco mode (Yorkshire miser!) so haven't had the full benefit of air con yet.

I'm never close enough to get the car cooled before I need to leave. Departure time in the morning is around 6:45 so before any real heat builds up in the car. And when I pick it up at lunchtime after charging I need to get back to the office quickly so just wind all the windows down if it is like an oven inside, which it has been lately..

That would be the Zoe...one of the reasons I chose it was the ability to defrost the car by timer or app (or even by the remote) in winter..I hated going out to the ICE cars I had in winter to start them up a half hour or so before my commute!

I wish my car had this feature! Plus programmable charging start/stop times.

I'm enjoying how effective wide-open windows are in cooling the car down in the warm weather.

Thought the votes would be closer, especially as it's quite hot outside at the moment!
When I am hot I am uncomfortable but it wouldn't stop me driving... I can always cool down pretty quickly with open windows... but when cold there is little alternative... stay cold or use the heater.

I am not so surprised at the bias towards the heating. :)

My Japanese Leaf can't really precool, it always runs at 26 degrees for preconditioning. Wish that the software could be updated!

I didn't realise that the Japanese Leaf set-up was different from the UK. My UK leaf was originally set to 26 but I had the option buried deep in the Carwings menu system to change this, now set as 16 for summer :D A great little feature where you can turn on heating / cooling remotely!!

Yeah, I am sure the headunit could be updated to make it selectable, it's all just software, but Nissan don't seem interested in that sort if thing. I just need to buy a new car :(

The 2012 Japenese leaf definately does pre-cool. I have one.

In theory the in-cabin temp is something like 25C -- too hot IMO, yet in the current baking hot weather a pre-cool gets the car, well very nice and cool thanks (say 18C).

Yet in the less warm weather a pre-heat gets the car too warm, and humid..

So not sure what's going on with their sensors and algorithms, but there's definately scope for improvement, at least it DOES work well in the extreme cases (<5 C, > 23 C )

I just like to be able to walk out of my door at the same time as the Audi driver across the road, unplug and get into my defrosted car and drive off while he is running his diesel engine and scraping his windows...

The cars both live in the garage so morning defrosting is rarely an issue.

But I'm the one walking around in a t-shirt in December so for me pre-cooling is a godsend.

Last year at the end of a gruelling day at Legoland the Model S interior temp was 44 degrees. After 30 minutes of aggressive remote cooling I got into a car whose interior was at 15 degrees.
