Exactly, especially in a BMW which has always been a performance oriented vehicle first and foremost. Why handicap the vehicle. The 45e already has to haul 800 additional lbs of battery, electric motor, etc.
This is not a damn Prius.

No, it's not a damn Prius. It's also not a damn Ferrari.

BMW also makes Minis.

Nice to have choices.

Let me get this straight, you prefer that your X5 has an I6 with 100 less HP?
Don't think I have ever known another man who would have that preference along with a Mini or Prius in their garage.

Will you please stop? You come off as someone with the maturity of a 16 yr old. Please think a little bit prior to posting, you are really becoming an annoying read.

My wife drives it 95% of the times in the comfort mode.

I like comfort mode and use it most of the time. Sport is much more fun and is a totally different vehicle when that mode is engaged on an M50i.

Because of several reasons...

The EV motor provides enough power so that the power:weight ratio is identical with the 40i, but the torque is higher. and produced instantly from zero RPM (i.e., stopped).

Also, while except in sport mode, the default drive mode is electric when you start out, the engine is modified to handle the extra starts so it can retain the expected longevity and being called upon when someone asks to go a bit faster. To make this much more seamless, once underway, instead of using the starter motor, it uses the EV motor as a tow start device, similar to what you might do with a manual transmission with the slow engagement of the clutch, so it is very smooth and much different than on an ICE with start/stop engaged. The only time the starter motor is used is from stop and the vehicle is not already moving. It also has different dampers on the engine to handle the potentially more frequent start/stop cycles at higher road speeds.

Since introduced to the world in 2018 as a 2019 MY (2021 MY in the US if I remember right), they have lots of experience with the design capabilities and reliability, so the 2024 MY coming next year will have more ICE power while (hopefully) retaining the reliability. On that, time will tell.

You can think of it like the 40i with more starting torque and in-town efficiency (and it's not bad on the highway - 28-mpg is fairly easy to achieve on the interstate or higher), so if you liked the 40i, you'll probably like the 45e. Torque may build quickly with BMW turbo engines, but it's instantaneous when augmented with a decently sized EV motor in the chain. Don't knock it until you've tried it for a bit.

Its fuel consumption is similar to the Lexus GX460 I had and sits at 13-14 mpg city driving, except it's significant faster. Seems without a hybrid system, V8 engines get terrible mileage. Now that my break in period just ended, I'm expecting lower numbers.

The X5 40i delivers its 335 lb ft max torque at 1500 rpm and carries it to 5,000 so for all intents and purposes it is always in the max torque zone, no waiting for torque. You will be brake boosting over 2,500 rpm if drag racing or playing with a Draggy device from a dead start. The M50i and X5M will snap your neck down low with nearly 600 lb ft(actual).
The future for X5 PHEVs is bright as the full strength B58 should eventually be working with a more powerfull electric motor. That could easily be well north of 600TQ and a hoot to drive at that point even at nearly 6,000 lbs. The meat eaters get interested in that range as torque is what makes a vehicle fun to drive.

My m50i on a road trip in ECO PRO mode - 26.1 MPG. She can sip the gas in the right conditions. 180 mile trip from Eastern Shore 72 to 75 MPH. I find that is the sweet spot.

One stretch of highway drive under idea condition has no meaning. What is the life time average MPG?

I repeat give one of my real life example. Road trip from Tahoe back to SF. The section from Trukee to Sacramento, I can get 55mpg from 45e in sport model at the same time the car regen charge battery from 3% to full. Does it have any meaning??!!

Sweet indeed for the monster V8! Thanks for sharing.

Once up to cruise, the amount of fuel is mostly the result of drag. Weight can affect drag as it tends to deflect the tires more, and may have wider tires, but on a flat road, it doesn't take all that much power to just maintain your speed and the efficiency can be decent. It's when your speed changes or you have to go up an incline where you'll take more energy and the efficiency goes down. More cylinders have more internal friction, but there are many other aspects that determine how efficient an engine is. Most vehicles can beat their EPA ratings when the conditions are right. A long trip using the cruise control is not the use case the EPA uses, so one would expect there to be differences. Then, it comes down to drag, and that goes up quickly with speed.

What’s typical range per tank on a highway drive 425-500 miles? About to move from a F15 35i to a M50i.

[starlights]

I had recently posted in a different thread that I was very pleasantly surprised that my new to me CPO 2020 X50i gave us an average of 25.6 miles DC to Maine. Used Adaptive with cruise 80% at around 70mph average with pockets of traffic backup on NJ turnpike and in MA. In town getting around 20 mpg.

X50i is around 456hp vs M50i that is 523hp.

Gas mileage is good, similar to my BM3 stage 1 N55. Tank size is also the same, and I'm filling up every 2 days, similar to the N55. Gas is going to be used regardless, so it really doesn't matter. It's better than my 18 Lexus GX460 that does 6mpg and better than my friend's GLS 550 amg that is a real gas guzzler.
