It's not really that relevant how much it costs to charge from low % to 100%, you don't drive it down to empty and then charge it back up again like an ICE car. You'd just plug it in daily and replenish what you used while you sleep and you wake up with a full charge. The cost to run depends on how many miles you do and how hard you drive it.

You should be able to get roughly 4 miles per Kwh when driven inside legal limits in the real world. Ignore any range claims from any manufacturer, WLTP is not very real world. How much do you pay for your electricity? Divide that number by 4 and you have how much it costs to drive per mile.

It is usually well worth getting on an EV tariff, you can pay as little as 10p/kwh for EV charging overnight. OVO's tariff has no impact on your normal day rate but it only covers EV charging. Octopus' rate covers your whole house usage in the cheap period but it has a higher day rate.

OVO us usually better if you don't have solar or battery storage, Octopus is usually better if you do or can offset a lot of energy use into that cheap period.

My average over a year is about 320W/mile with the 3 performance so about 3 miles per kwh. I use the acceleration and do a lot of shortish journeys in addition to my commute.
 
Haven’t you have the original performance? A lot has changed since then in terms of efficiency and a new performance will go 20% further on a charge. 4 miles per kWh is realistic for a new long range, performance is less but not that much less.

As a point of comparison, the original performance has a similar WLTP rating as a new RWD car but it has 15kwh more energy onboard.

Yea its a 69 plate. It doesn't have the fancy octovalve which I think makes the biggest difference.
 
Yeh it’s pretty amazing the heat scavenging it can do. Watching it such all the heat out the cabin on a sunny day and dump into the battery for better performance and efficiency.

Likewise the other way round after DC charging it will take all that heat and put it in the cabin on a cold day.
 
No heat pump on my 2019 Model 3 SR+ so in winter I do struggle to stay below 300 wh/mi but it only takes some reasonable ambient temps to make a big difference.

Couple of weeks previous I managed a 200wh/mi drive home as it was 15C, sunny and the car had been sat in the sun. After reading this above posts I again realised it was 16C but no direct sun so I thought I'd try that efficient drive again.

Simple rules, accelerate with normal traffic (harder than you think in an EV) up to the speed limit. On the 8 miles of 70mph bypass stay left so averaged 60-62mph. Result was below :)

I think you meant heat pump. The octovalve is simply part of the heat flux management system where it’s innovation is the packaging space it takes up. Not its actual function as a valve system.

I meant octovalve. I know the heat pump is more efficient, but the valve does a load of other things as another poster pointed out so I suspect having that saves more than the heat pump (although I think they were changed at the same time so hard to check). I think for me with my shirt runs it would make quite a difference, but not enough to justify changing the car.

Yes its almost as if the valve part of the 'octovalve' manages which way the heat is pumped...
 
Quick question on blended braking, should it be active all the time as when I'm fully charged it doesn't kick it, and even when it's say 75% or below it rarely seems to be working.
 
I don’t think it’s a feature of U.K. cars where limited regen is available.

Certainly my car will only apply the brakes on autopilot or when AEB kicks in (or I hit the brakes of course).

Ahh that explains it. I've seen it pop up a couple of times but it's so infrequent I can't remember what I was doing at the time.
 
Just to give you guys a laugh, my work have recently made a big deal out of installing some chargers (and 1 pair is 22kw, so I'm limited to 11 but still..). They're charging a nice rate of 60p per kwh. I've told them nobody is going to use them at that price, either make it free of something reasonable like 30p.
