Miles per kilowatt

Ok, so I have an ix 40, just covered 1,000 miles and here in the Uk thing are still pretty chilly, but have managed to get 3.1m/kw out of the car so far

3.1 is impressive, is that figure since factory, or just on one journey?

I've had my iX40 for nearly a week and over the 500km I've driven I'm averaging 18kWh/100km, more importantly it's only costing AUD$4.19 per 100 km in electricity.

The figure was range and data for the charge, a few journeys, 2 of which were 80-90 miles each..
My average for the full 1,000 miles is much lower as typical journeys are circa 5 -10 miles here and there.. still working out if Idrive 8 and will try and find the total figure…

I think you would struggle to get to 3.7 my i3S overall average is 3.8 (its 1000kg lighter), my iX (50) is running at 2.5 for the first 1300 miles - short runs very heavy on the electrons typically 1.6 for a 10 mile journey not helped by the terrain where I live quite a few 1 in 4 hills. The i3S gets to 3 miles/kWh after about 10 miles. Preconditioning didn't seem to make much of a difference.

I have been driving ix50 and total milage is around 1400 miles. Factory average is 3.6 km/kWh, around 2,24 miles/kWh

Not much long drives, only 15-20 minutes driving each time, city and highway mixed.

21 inch winter tyres and weather is between 0-10 degrees.

It fluctuates massively and doing town jobs, a few miles here and there do knock the stuffing out of the battery range, I think this is because the car uses the battery to condition the batteries if you jump in and go and not take advantage of preconditioning whilst charging to limit the battery drain. Lastly, from stationary, it is having to shift 2,400kg, that initial push is a hit on the battery. On a long run, it does return much better results… I drove into central london on Saturday, drove to twickenham (stuck in traffic mostly) blasted around Hampshire and Berkshire and tested the top speed and sport mode for 20 miles and still managed and average 2.9 kw/mi.. and a totally mileage of 190 miles… if I’d been more conservative I reckon I could have got 220+

Are you using the maximum regeneration mode ('B' rather than 'D')? Ive been told by my dealer that this can have a dramatic improvement on range

That’s a good question. I have been almost exclusively using the ‘D’ mode. I find it such a pleasure to drive, and its automatic adaptation is amazing. The ‘B’ mode is probably quite clever too, but I find it makes for a clunkier drive.
Out of curiosity to all others posting their efficiency above, which modes are you using?

I only picked mine up today, so have no real world figures yet - I was just going on what the dealer mentioned during the hand-over this morning!

B is good for town driving, single pedal driving and big regeneration. D is better on fast roads imo, as auto adaption is really slick, however when in b mode on faster roads the brake lights are a bit more sensitive and can be unnecessary alarming to people behind.

I agree with @ExiPaceOwner

In adaptive D mode, I am rarely using the brakes, only for full stops at traffic lights, when a car stops ahead, or for some turns etc.

During the drive, most of the braking is handled by the adaptive mode in D.

Firstly, congratulations. Once you get some idea, would you please share the figures with us?

I have a 50 and have set D mode with max regen which for the roads where I live lots of hills is great the adaptive is fine in traffic but I don't see much and in adaptive the car coasts when it doesnt see other vehicles and will accelearte itself to 70+ down hills. My from factory is 2.4 miles/kWh 7/12/2021 and from the dealer 31/12/2021 2.5 if I see an overall of 2.7 I'll be happy most of my journeys to date have been 10-15 miles (+ 1 at 400 miles) and never pre conditioned.

Actually per spec for the 4.0 that should be 22.5 – 19.4 kWh/100 km which is 4.3 to 5.1 km/KWh I believe. The 5.0 is similar. I have not been able to get close to that in the wintertime. I agree the battery conditioning plays a role there. Interesting to see how this evolves. Yet my model X, even in winter time, averages at 23 kWh/100km, which would make me conclude the Tesla has better power management. Perhaps the tires play a role, tire pressure is prety low on the iX.

I just did a road trip driving mainly in B mode and got 3.2 miles per kwh outgoing cruising at 70 where possible and 3.6 miles per kwh on the return at a slightly more sedate 62mph. Both trips were 15 to 18 degrees C and dry days. I am really impressed by this in my iX40 for such a big heavy car!

That’s really decent. Things have improved as the weather has warmed up and now getting 220-240 miles per charge.
The challenge I have is innate inability to stay at 70 or below and tend to hover around 75-85, on this basis the range is much better and the availability of chargers in the Uk is pretty top notch too, InstaVolt seem to be well placed for most of my 300mile+ trips..
