Not quite, but even on a scorching day, when I have to commute to Milton Keynes from Newcastle (once a month), it can be cool when I set off at 4:30am. Last time it was 11-13C most of the way there (3.4 miles per kWh, no aircon) and 23-26C most of the way back (4.0 miles per kWh, 18C on the aircon). Maintaining 72mph there and trying to maintain 75mph home. That's quite an efficiency difference. Admittedly, the average speed home was a little slower because of traffic in places, but do also consider I was using aircon with a 7C difference between ambient and maintained cabin temp.sidehaas wrote: ↑Thu Aug 11, 2022 5:44 pmHave you moved to the arctic??monkeyhanger wrote: ↑Thu Aug 11, 2022 5:29 pm 3.0 on my Born is nothing to write home about vs 2.3 I had on my ID3.

Your car was built with the 3.0 software that everyone who's had their ID3 a while is keen to get. Irs not much better than 2.3.
New cars are shipped with 3.0. The 2.4 workshop recall and 3.0 OTA process is for older cars which typically have 2.3 on them.
Fair enough, what I would expect if it's the same as my car (2.3 ex-works) is this: for short trips at low speeds in winter the battery heating won't come on and so you'll still be able to get decent efficiency unless you use HVAC heavily (HVAC makes a big difference over a journey of just a few miles when cold). However for longer trips efficiency will be in line with what you've seen before, I suspect because the battery is being heated up, but only in a staged manner after you have been driving a certain time or used a certain power level or % SoC. It's a change that will reduce running costs for people doing lots of short journeys but not make any difference to people wanting to eek out miles on a longer journey.monkeyhanger wrote: ↑Thu Aug 11, 2022 6:06 pmNot quite,but even on a scorching day, when I have to commute to Milton Keynes from Newcastle (once a month), it xan become when I set off at 4:30am.

Maybe we won't know until we're in Winter. As someone who charges at home, crap efficiencies for short journeys in the Winter is not a bother for me, i'll just charge a little more often. Hopefully long winter journeys aren't too badly affected after the initial warm-up cycle as the consumption discharge at motorway speeds should hopefully maintain the battery at teh temp it wants to be at for reasonable efficiency.sidehaas wrote: ↑Fri Aug 12, 2022 6:11 amFair enough, what I would expect if it's the same as my car (2.3 ex-works) is this: for short trips at low speeds in winter the battery heating won't come on and so you'll still be able to get decent efficiency unless you use HVAC heavily (HVAC makes a big difference over a journey of just a few miles when cold).

But, having said all of that, it may well have been slightly further optimised in 2.4 and 3.0 than in 2.3 ex-works so may not behave identically.
