I'm glad the EPA on my iX50 is 320 miles. I get 250 miles regularly and 170-190 in bad winter/wind conditions.

Absolutely. Here in GA I can even get 380 miles on my IX50 with 21 wheels. That is rare though. I never drove in efficient mode, always in personal with adaptive regen and besides hi ways in B mode. Anyway, real life is 320 miles, and 280 in our current temperatures in the 40s. Imho horror stories about range of EV's are boosted by those, who want to have their 8 cyl SUVs running to get back to them in comfortable temperatures while they are sipping their coffee in airconditioned Starbucks and impress the audience with the engine noise departing. People hate change and don't want to accept any inconvenient truth.

EPA on our iX is 315 miles w/ 22" wheels and we still get 370-380 miles real-world after 3 months. EVs shine in Arizona weather!

Throw in the various discounts on rapid charging that BMW themselves offer and even other providers, and public charging is deeply discounted.

How do you get these discounts? All I have is chargemaster/BP pulse free for a year.

I am also suffering from poor range from the ixM40. On a full charge the car is reporting around 180-190 miles in cold UK weather. However I only ever achieve around 120 miles @ 1.1-1.5 miles/kWh. My previous car i3s was much better than this.
Whilst I understand every EV falls foul of poor range in the winter, the ixm40 has the worst performance….going from summer range of 220+ down to 120 is unacceptable. I feel the car is being missold to UK customers As you can never trust the range indicator in the car…..I drive 1 mile down around town and see 2 miles drop off the range indicator whilst driving. For a car that cost £80K+, this is very poor.

Took the car into BMW for a recall service, and they advised me the car is fine. However the BMW rep did note that he has noticed the iX40’s are losing range faster than the 50/60’s….but not sure why.

They advised me to pre-condition the vehicle every morning….will this really help if the car is not plugged in?

What are UK owners achieving in terms of miles/kWh? (For m40 owners only pls, as the m50 seems ok)

@RazorRazqq I'm getting 190-225 miles range in the winter. Mostly short journeys of 3 miles or less around London. I have an ix40. Did a longer journey of 8 miles round trip yesterday and got 3.0 miles per kwh (average speed 25 mph) and that's with heating, heated seats and heated steering wheel on.

Those number look great. I’m def not getting that with all the heated seats/wheel off. I’m wondering if the B&W sound system plays a part in this as it has 20+ speakers to power.

@RazorRazqq I seriously doubt that a few extra speakers are doubling your energy consumption. Have you checked the basics, like tyre pressures? It could be your tyres are under inflated.

Do tyres make that much of a difference? They are slightly low…I will top them up later to check.

@RazorRazqq My trips rarely involve going uphill. All straight level roads. Are your journeys involving going uphill, even a little bit? That will impact your efficiency. I also leave my car in D, adaptive regen on high and take my foot off the throttle as soon as I'm up to speed and let the car coast.

@RazorRazqq Err, yes. Under inflated tyres = more of the tyre will be touching the road surface, increasing friction and rolling resistance, and these are big fat tyres on these cars.

That's going to increase how much energy it takes for your car to move. Whether by 50% I don't know, but under inflated tyres impact fuel consumption, whether EV or ICE.

You have seen my figures on the other thread re: iX40 real world range… I also have B&W, massage seat, heated panels - the lot. I have the cabin heater set to 20.5C heated steering wheel and 2x front seat heated. I usually pre-condition cabin approx 15 minutes before each journey… Two occupants and a 35kg dog in the back. Some of my short trips exceed 3mi/kWh just now and most in the mid to high 2mi/kWh plus. Not too many hills here, so mostly fairly level with a mix of country roads and some dual carriageway per trip with each trip no more than 10 miles.

thanks for the details. Your setup pretty much mirrors mine, doing similar journeys to you. Just can’t work out why I lose so much power.

we’ll inflate the tyres more and try preconditioning to see it that helps. Otherwise will take it back to BMW to look at it again.

0.2 bar = 3 PSI so it could make some difference but certainly nothing close to what you are describing. I would look at the usual suspects: Acceleration, drive mode, and regen/recuperation. Set drive mode to eco/efficient, set regen/recuperation to auto (or high) in D mode and start your regen about a quarter mile before you hit the stop light with very light "braking" instead of slowing down all at the end like ICE drivers. If you are driving in cold weather, pre-condition the cabin interior while charging and while plugged-in. Keep your acceleration to 25 kW or less on the power meter when accelerating from a stop.

I can almost guarantee with the above changes you'll be shocked by the range.

Drove an iX (50) for the first time today. We had the car for a few hours up in the Lake District. I’d been thinking about an iX 40 due to the cost of the 50 in the UK, but put off by some people getting miles per kWh in the 1.x range.

We did 4 journeys over the few hours 16, 18, 29, 5 miles in length, with a mix of 30,40,70 mph roads. The car was not pre-conditioned for any journey and we used the cabin heater, heated seats, heated steering wheel, radiant heating, rear window heater throughout the journey as it was raining and fairly cool around 10c.

In the end we used 23% of the battery, which I think is 3.11 m/kWh? Is this a good figure for the iX50 and would the iX40 be much worse ?

Thank you

In principle the iX40 should have better consumption than the ix50 (with same equiment, same weather, same road and same driving style), given that it has the same motors but a smaller battery, which means it's lighter - ix40 has 2.440 kg and ix50 has 2.585 (+145kg or +6%).

So for ix40 vs ix50 it boils down to:
1) smaller battery / less range (74,1 kw net vs 108,8 kw net +47%)
2) lighter (better efficiency or miles/Kw)
3) less performance (although same engines tuned down; I testdrove the ix40 and is more than enough for that car)
4) slower maximum DC speed (150kwh for ix40 vs 195khw for ix50)
5) may have less optional equipment available (depending on country - eg B&W sound, rear steering, air suspension)
6) much cheaper (where i live base model ix40 €86,5k vs ix50 €116k or +34%)

If you travel long distance often then ix50 will save you some minutes / hours. If you seldom do long distance travel then the ix40 will be virtually the same and will have marginal better consumption

IX40 here. 300+ mile trip today. 90% motorway. Fully loaded with 4 x adults and luggage to the roof including the kitchen sink! A/C on, radiant panels on, Kept between 75-80mph most of time. Mix of rain and sun with temps 12-14C. Midlands to Cornwall. Worst leg was 2.5mi/kWh best leg was 3.08mi/kWh. 100% SOC at start. First charge after 100 miles with preconditioned battery, pulled 118kW at IONITY charger at start of charge, so 30 mins for brunch was perfect… No regrets with the range of the 40 in the South of the UK. And trips to southern Spain is fairly painless…

@J78 Could the iX50 have better efficiency in the real world than the iX40 though? I ask because it's got air suspension that the iX40 doesn't and my last Mercedes with air suspension would automatically lower the suspension when going above 60mph to reduce drag and increase fuel economy. Just wondering whether BMW do the same with the iX50?

Probably you have a point with the air suspension as it reduces drag on lower setting. My comments were only for same spec cars, where I live the iX50 doesn’t have air suspension as standard and both models have same base specs, including 20” wheels

 

[NomoTesla]

iX lowers the suspension by a meager ½" in sport mode. That won't make a material difference in range when starting with an 8" clearance.
