First winter. Wh/mi ouch.

[bainsy]

the whole of summer I’ve been playing a game of how long I can get my overall wh/mi down to.

16,500 miles I’m on 289wh/mi

That’s now crept up to 290. Winter truly kills any efficiency in all cars!

You have to admit, though, that ICE loss of range is far less of a problem than EV because ICEs heat the cabin on what is essentially waste heat anyway, whereas EVs have to divert their limited drivetrain energy to convert it to heat.

Indeed. Long time since I've owned an ICE, so things may have improved, but the "set off cost", in Winter, of warming the battery and cabin (both using "fuel") I reckon is similar (unless things have improved in ICE world) to the ICE having to get up to temperature, and pollution controls kicking in to prevent unburnt stuff coming out the exhaust.

Although some ICEs do warm up remarkably quickly

Do he posh ones have pre-condition? Is that an electric heater, or does the ICE start?

I would imagine the ICE starts, but not having driven one in years (and having no interest in going back) I wouldn't be able to tell for sure.
I do hate the very cold mornings in the neighbourhood when multiple cars are running and spewing fumes (which are especially stinky because cold engines run on a richer mixture) while people wait for their windscreens to thaw.... Sooner that goes away the better.

there are things for heating cars up. One of market leaders is Webasto.

Winter is least of my worry - my wife kills the efficiency more than winter She is yet to take the right foot off from her mini cooper style driving!

 

[WllXM]

To illustrate and for the data nerds out there

My MY efficiency over the last month :

What it was back in July:

Essentially, in November, I used 150kWh to do 343 miles. So yeah, twice the battery capacity to cover the 'rated' WLTP mileage.
That's roughly 180 miles max range on a full charge for my MYLR. City driving, very little motorway.

Can confirm every recent ICE I've driven that has pre-condition via mobile app starts the engine (being either AC in summer or heating in winter).

Been driving my SR+ for nearly four years and still manage to mis-calculate my cold weather range!
Never been that low before and reached home with heating still on but my brother who has a 24kWh Leaf said he would have had the heating off for the last half hour with windows open to stop steaming up!

... and all the folk with EVs are on the phone to Autoglass having cracked their windscreen using remote Max Defrost

ever heard of anyone having cracked windscreen with remote max defrost.

jesus, probably all mondeos in existence have heated windshield.

Does your Y have a heat pump? If so, I thought the heat pump is suppose to reduce the variation a bit. Though my old Nissan Leaf that had a heat pump was still S***T in winter, it really was a true city only car when temperatures hit below 10 degrees.

ALL UK model Y have a heat pump

heatpump actually increases the wh/mi consumption at the beginning of the journey

Just done a 460 round trip over 3 days North to Midlands and back, well loaded - 2 adults, 2 dogs (50kg together), 18C AC plus loads of kit and presented etc. Day Temp never above 2C, nights -4-5C Tesla Y LR outside every night. Averaged 303 Wh/mile cruising mostly at 70mph motorway. Summer same journey 253 Wh/mile. Approx 17% drop in Wh/mile. Cost of journey -home charge then SCs £44, approx 10p/mile. So range drop but still very cost effective, not to mention the comfort. The odd extra stop for 15-20mins SC (plus toilet break etc) very worth while I think.

We did some local trips on Saturday, I used the climate control left on every time we went into shops. It was very toasty upon return but the efficiency was tragic but...I DIDN'T CARE!

Up to when I got a EV, used to idle the ice car for such things but now I no longer have to, whilst not risking it being stollen at my expense. Hopeless if it was a diesel as it took a very, very long time.

My house heating is also on 24/7 based on tempeature being set to 20 celsius except from 23:00 to 06:00 which ill let it drop to 15 celsius.

Some of us have come to realise that you only live once and the more comfort the better hence in my case at least an EV helped the situation plus saves the environment a bit.

 

[djtaylor]

Well technically it's not the planet that needs saving but the humans from themselves. The planet will stick around long after we've been turned into crispy croutons.

If I turned my heating off and went away for the weekend in the middle of Winter I would be surprised if it dropped more than 1C !!

Your house needs a nice winter overcoat!

 

[Tony Hoyle]

That's impressive.. I get a 2 degree drop overnight (22->20) and thought that was good.
