Definitely not all motorway - it's Cornwall!
You might be ok then the owner that posted his real world figures in the short while he had the car was posting 299-310 for mixed driving in decent weather, so there is your 3.1 mi/kWh.
There was a strong Southerly wind yesterday/Tuesday (14MPH @ 180 degrees) so this will not have been helping the M/kWh. The journey described was into a head wind the entire journey.OK, so here's another update. As a reminder, we're talking about the IM6 Long Range. Today's drive was at 14 - 16 C.
- Total distance:185
- Total motorway miles (70mph): 132.2
- Trip efficiency 3.1 mi/kWh
- Mode: ECO
The trip was in 2 legs, I did top up the car at Tesla supercharger at Gloucester. The 1st leg is interesting as it's (almost) exclusively motorway so really a worst case. At 4am traffic allows pretty much constant 70mph (although there was a closure at junction 13 which caused a slow traffic and ~10 min congestion). Here's the details of the 1st leg
- Starting charge 96% (373 mi range)
- Total miles 140 miles
- Motorway 128.5 miles
- End charge 51% (206 mi range)
- Trip efficiency 2.9 mi/kWh
- Heating was off most of the time, I had it pre-wormed at home and surprisingly having a coat I was OK. Turned it on towards the end of the journey for ~10 min.
Having said that not sure how accurate the computer data is. I lost 45% on the journey, with 100 kWh batter this is ... well 45 kWh, That'd give it actually efficiency of 3.1 mi/kWh. But then again I've topped up 44 kWh and I am almost certain that the battery was at 86%, unfortunately I didn't take an after charging picture of the battery status so I can't confirm it ant it may just be my middle-of-the-night brain misremembering things,
I've arrived at destination with 78% charge (318 mi range).
I've also did a small 9.2 mile dash in the evening on the country roads, here I got 3.4 mi/kWh and I dropped to 76%.
I'll be heading back on Thursday afternoon. My experience with ZS EV on the same route is that return journey is ALWAYS much more efficient due to much heavier traffic, slowing down the trip and boosting efficiency. Let's see how IM6 is going to be on that leg.
And now, considering it's 10:30pm and that I'm up since 3:30am I'm going to bed. Have a nice evening everyone! I'm looking forward to the morning digest of this post.
Goodnight
The members figures matched the real world figures posted by another owner on a different site, so the wind hasn't impacted them too much
Well that is like complaining your new 911 turbo does 9,0l/100 km, when your Prius would have done 5,0. If you want economy in a tin can or you want the power in the beast from the east
Id prefer it to be more efficient and have the speed if possible, those figures are poor and that was just his constant speed test, not attempting to drive it like a PorscheWell that is like complaining your new 911 turbo does 9,0l/100 km, when your Prius would have done 5,0.

what was your average speed?
Thank you very much for the update. Very useful. Look forward to the heating test. Not sure it will make a massive difference as for long journeys once the cab is at temp it does not take much energy to maintain the temp.
Sounds exactly right to me. A 46% increase of SoC means 46kWh has been stored in a 100kWh battery. The charger has supplied 50kWh, which equates to an 8% loss = charging efficiency of 92% which sounds about right for a DC charger (i.e. better than 10-15% loss with AC to DC conversion).
It sounds good. Nothing wrong with this. The linearity of the SoC scale can be off. And on a new car it could be down to lack of balance charging the cells and lack of driving it under <10% and charging to 100% again, for it to be properly calibrated at the SoC scale in this car. And the usable energy is 96,5 kWh in the battery. With Carscanner or similar app you can see multiple SoC indicators on the car, which is not exactly the same. SoC-display can be 100% when the SoC-real is 96,5%, which is the kWh limit it is set for, to protect the battery.
Each to their own, I'll wait to see the return journey figures, as they brought the average up last week but 2.7 isn't that efficient.
Average speeds:
