I thought it'd be good to start a thread specifically about efficiency stats.
I have only just got my EX30 Performance and I almost cancelled it after having seen some horror stories and videos about the efficiency of it.
However, after having done a couple of longer journeys this week, I'm a lot more comfortable with it.
I did a mostly motorway drive of 78 miles last night sticking at between 75 and 80 mph and my efficiency (according to the app) was 27.35kWh/100 miles. Given that I had lights, aircon and the stereo on for that journey, I think that'd pretty good given the house brick aerodynamics of the car.
What are other people's experiences?
Cheers.
Richard.

Hi Richard,
We are getting very similar figures with ours. My wife does mainly motorway driving and gets better figures. My journeys are more mixed driving and I have a heavier right foot so get slightly worse. All in all the range figures seem reasonable against quoted, similar discrepancies you get with quoted mpg figures for ic cars.

My latest charge saw me getting an efficiency of 26.8kwh/100mile. It could have easily managed 250 miles of range full to empty on A roads. Most of my speeds were around 50, 55, 60mph. Anything more it is a different story.
Last week Southampton to East Midlands on a single charge. Travel started at 8pm, ended at 11pm, no breaks. 184 miles on the trip, reached home with 6% remaining. Would have barely made 200 miles to empty. Speeds were 75mph all through, slightly above at times to pass.
I have to add. I got the car early April when it was a lot colder. The figures that time were nowhere near these.

I am still getting used to the idea that with kW/100 miles figures, low is good (all my life I have been using miles per gallon where low figures were bad).
We also have to remember that we are not all living in the UK. Most of the world used kWh/100 km, which looks very like kWh/100 miles, but gives a very different figure. (100 km = 62 miles. 100 miles = 161 km)
I have not reset my consumption figures in the car since I bought it. My car has averaged 29.8 kWh/100 miles since new, over a period of over 3 months with two different drivers, on all types of road in all traffic conditions.
We should also remember that the economy figures displayed by the car used by calculating the electricity taken from the car battery, not the electricity used charging the battery. Unlike putting petrol into an ICE car, there is wastage in charging a battery. It takes about 12% extra electricity (lost in cable warming caused by electrical resistance, inefficiency in changing AC to DC, and battery warming) to replace the charge taken out of the battery when driving. (Putting 30 kWh in to the battery will take about 33-34 kWh from the charger - and added onto your power bill.)

This is good stuff thanks team.
For the first time (without a Tesla) and an EX30 ultra trip to Gatwick airport coming up from the East Midlands (including luggage - let’s not mention the frunk - and family that’s 190 miles.
I’ve realised since signing up to the Tesla supercharger annual membership that not all superchargers are set up for non Tesla cars so having to plan this one!
If I do 70 on cruise control in approx 17celcius I’m thinking 180 miles tops.
Has anyone experienced any ghost battery drain when parked? Earlier software versions of the model 3 were notorious for losing 5% overnight which after a week in an airport car park is enough to spoil your hols!
Is this an EX30 problem??

We've had our car for almost four months and driven around 2200 miles. That's a couple of long journeys and then local driving for the rest of the time. We currently have an average consumption for that entire time of 25.1 kWh/100 miles. The last trip (around 40 miles), the average was around 24. Those figures come from the car's display.
The Driving Journal, however, is a complete joke. It comes up with 38-39 for the same trip. In fact, every journey that appears in the journal shows the consumption gradually getting worse. I have no idea how those figures are calculated so we've concluded that's another thing that's rubbish about the app.

I don't understand the journal at all.
A lot of the time mine doesn't even show a return trip. It either shows going somewhere and not returning home - or else returning home from somewhere that it didn't show us going to.
My odometer shows 15% more miles done than the journal does. Thats a lot of missing trips!
I must admit I very rarely even open the journal.

With a mixture of motorway, country roads and urban I consistently get around 200 miles on a full charge. Now there are so many more rapid chargers I have ceased to have range anxiety, enjoy the acceleration and always have the aircon on. Mainly charge at home.

This is a really fascinating thread and now I am getting to know my car I want to understand the efficiency stats more clearly. This is my first EV and I am not that mathematically minded so would appreciate an idiots proof guide on how to interpret the efficiency figures. Any advice will be appreciated.
