The issue is more than just the charge time. Imagine even if today, we have tech to charge a 100kWh in 5 min, equilateral to fill up a tank of gas. the power deliver needs to be 1200kW for the entire SOC. I think we are averaging to 85kW now. To charge my 85D from empty to full will take 1hr+

But my point is, if I use one tank of gas in a year. If these one tank is spread out to top of when my 32 miles EV isn’t enough, it really means 31 mile of EV is very good my most of my driving, I just need a few more miles per trip. if I have 250 miles of range, I will not need the ice. The other extreme is that one tank is one long trip, ~400 miles. I would say for that road trip, I will deal with the EV charging, mostly one over night chsnge with L2 at destination will do.

Really I am not against EV or PHEV, I have one. 45e is a good learning curve. 2 months in, I realize who is this really for. And more importantly who it isn’t for.

High capacity CCS (or Tesla supercharging) is a major load impact on the power distribution network. My dealer wouldn't install one because he would have had to upgrade his entire power system to support one, and it wasn't a reasonable cost:benefit deal.

CCS units can range from 25-350K today, with most tending to be in the 50K range. It's an expensive DC power supply that will need some significant cooling capability increasing the power needs overall. A really good DC power supply might be in the 95% range, so to get 350K out, that would require 368K in, not counting what it might take to cool the thing. That's a lot of current to be moved.

Large battery capacity is pretty heavy today. The medium sized battery in the 45e combined with the ICE isn't bad when you compare it to say a Tesla Model X, which is within a few hundred pounds of the BMW. So, for a larger range EV, instead of carrying around a large battery alone, you're carrying a smaller battery that you'll likely fully utilize on a daily basis, and an engine that is quick and easy to feed when the time comes...so not a huge penalty except for maybe the additional complexity. But, we've been making ICE based transportation for ages, and it's pretty reliable.

For me, the 45e is a good solution until the infrastructure gets built out to make a BEV or FCV a viable choice. Mostly EV operations and the freedom of going pretty much anywhere anytime with the 'backup' ICE.

The X5 45e is the best vehicle in its class! There are times I use the sport mode so my X5 can sip up some gas that's been in the gas tank for a while.

Seems like the 45e suspension has made this nearly a "non issue". Agree based on your experience?

I was worried initially, about ordering ours with 21"RFT's on Illinois roads after a couple years in an X3M40 on 19 RFT's...I have to say that after a week of mixed city, country and highway roads, I wouldn't hesitate to do it again. The car is quiet and the Hankook 21" are very compliant on the aforementioned surfaces. The air suspension is incredible and the 1/2" difference in sidewall height from the X3's is not as bad as I had thought. Now I haven't had to deal with any major potholes yet and that may be the hitch, but so far so good!

We traded our 45e in last month, but while we had it was not uncommon for us to get 40-45 miles without the AC/Heat on during the spring, summer and fall months. With the AC on it was about 33 and 30 with the heat on. This was 30 percent city roads with lots of lights and 70 percent at 50 mph with some lights. Granted this was me trying to drive it so I would get every bit out of it. So driving habits has a lot to do with it.

We had about 26k miles on it before we sold it. Hope it helps.

added benefits are better ride quality and efficiency (though not significantly more) and less risk of curbing wheels

I ordered mine (build date 9/19) with 20's for those same reasons.

Could explain what you mean by "more beneficial tire rotation"? It did not factor that in.

preferred tire rotation for square tire FWD/AWD moves the rear tires to the front and the front tires to the rear whereas staggered tires only allow for side to side rotation on the same axle

Is that because the 21s+ use different size tires front vs back while 20s use the same size? I didn't realize that.

What did you get instead?

We got rid of our 45e and 330e for something bigger… we ended up getting the X7 M50…. Yes it screams the opposite of gas savings…. But we have 1 car sitting at home doing nothing so we sold both to get one and saved 500 a month in the process.

yup, that's "staggered"

Rotation get more complicated with summer tires. Most are either directional or inside/outside specific. All my other bmw with summer are like that. So for side to side rotation, I need to take the tire off the wheel and swap side to side.

Exactly...or NOT and hope that your alignment is dialed in. This is by no means a boast as some would scream, "this guy doesn't maintain his dream car very well!" We will see how the first 5K miles go, but that will be this Spring after the winter shoes come off...and it will be a square set up that can only go front to back as they are directional and asymmetrical.

[eelnoraa]

Tire rotation should not impact or affected by alignment, but in mount/remount tires is such a hassle. In my ownership, I have only done tire swap rotation once because BMW’s factory camber is too negative on the rear. The tire wear is extreme inside bias. Once I learned, I zero out rear camber and I just don’t do rotation for my stagger setup bmw anymore.

But then the main reason for me to run zero rear camber is because I hate factory under steer geometry setup.m. Add stagger, our cars under steering severely. While not to the same level as FWD car, but once you experience what neutral steering feel, you will never go back

So I run my battery already empty yesterday. The charging stat show car took in 19kWh from 3% to 100%. This is well above the 17kWh that we are supposed to get. This may explain why getting 31 mile EPA is east.

But my question is, do we really get usage of 19 instead of 17? Oh is is more of summer behavior?

no, you still have 17.1kWh of usable capacity. it always takes more energy to charge than the energy stored. this is known as charging loss. i regularly take 19-20kWh (sometimes 21kWh) when charging from 0-100% (US spec) throughout the year. here's a screenshot from January winter in Virginia

[eelnoraa]

So the kWh shown in MyBMW app is not what the car took into battery, but what the car took at onboard charger level?

neither

[jad03060]

A couple of things:
- converting ACV to DCV is never without its losses in the power supply. The EVSE is supplying ACV, and the batteries need DCV (that power supply is IN the vehicle). Expect about a 5% loss just from that conversion when using level 2, more when using a level1 EVSE.
- both the power supply and the batteries will heat up during charging, so the vehicle will be 'wasting' some energy to keep things cool, more so in the summer and after a long use versus say recharging during off-peak time after the vehicle has had a chance to cool off by itself without using the on-board cooling.

Will be doing 56/90 testing soon (ala TeslaBjørn)

Stay tuned!

Same boat here - I have an x3 m40i currently and just ordered the 45e. Was curious how I'd truly feel about the 45e after consistently driving it compared to the beast of an m40. Are you loving it over the x3?

Have owned both. You can throw the X3 M40i around in ways that would not feel comfortable for anyone in an X5 45e.

I can say the steering in the MSport doesn’t seem to have that center dead spot that annoyed me to no end on the xLine.
