For those unfamiliar, REST allows you to keep residual engine heat warming the cabin after you’ve shut the engine off, but still turn on cabin heat. With a battery that’s flat and a warm engine the car will activate REST.

Tried it once on a 2008 M3. Ended up fogging up the car. I'm not missing much

Curious, what sort of (full tank/full battery at departure) highway range are 45e owners seeing on road trips? 90% of my driving is local and perfect for how a 45e is designed. However, I do take a 665 mile road trip (all flat, easy highway miles) several times a year and am wondering how many miles max people are seeing on a road trip when speeds on the highway are high - such as 75-80mph. I know the fuel tank is smaller than 40i - and some suggest that the mpg on a highway road trip once the 45e is out of BHEV power is lower than 40i - so curious what is happening in the real world.

~500 miles (give or take) on a full tank/battery

while driving, the vehicle will likely never let the HV battery deplete to the point it is only being powered by the ICE (289bhp), so ICE-only mpg figures aren't seen in reality. technically speaking, even though it may display 0% on the instrument cluster, it's not completely depleted. the only issue i've read when the HV battery is depleted is the HVAC system deactivates but then reactivates after a few minutes of driving that restores enough HV battery capacity. i've never read or heard of a decrease in power.

I leave it in hybrid or adaptive on the highway and usually let the car do what it wants with the battery. Keep in mind that even if you are out of battery range on the dash, the battery is not completely dead. The car saves some back for other functions. This results in most of the trip using the engine, but honestly I'm getting pretty good mileage out of the engine too - usually 28-30. Can't complain about that.

There is a lot of smoke and mirrors with all this PHEV, EV, whatever. Many hidden costs, problems, on a number of different levels.
Sure, EVs will be the obvious choice down the road when they can re-charge in 20 minutes and go for 1,000 miles. We are obviously not there yet, no where near that point where they are preferable to John Q. Public.

Starting with a full battery in the summer (all of the heat is via electric, so that will affect EV range more than cooling loads), I got over 500-miles. Once the battery was depleted, I was averaging about 28-mpg (US) at about 75mph on cruise.

I expect it to drop at least 20-miles in the winter for several reasons:
- the air is denser
- running winter tires that don't have the same rolling resistance
- the need for heating
- lights on more
- seat heater
- rear window and mirror defrosters

. Haven't taken a longer trip in the winter yet so can't say for sure what the delta will be, but I know it will be less than I saw in the summer. It's far longer than my bladder can handle!

Hey that is great - very helpful... and I am pleasantly surprised to hear that 500 miles is a realistic road trip range.

Not only is the range good, as long as you can plug in overnight the mileage is fantastic. 73mpg over 540 miles with two 110+ mile day trips with 35 to 37mpg.

[mermar]

yes - I know that my typical "around town" mileage will be amazing (mostly on EV mode given the length of my typical errands) - I am just trying to understand what to expect on a straightup highway road trip. Leave the garage topped up both battery and gas and hit the highway for a 600+ mile flat roadtrip. I make this trip 4 times a year or so and was wondering what kind of range the 45e might have (given the smaller gas tank). Sounds like that number is around 500 miles at 75-80mph on highway. Once at my destination, yes - I will plug in and be mostly electric mode around town.

i miss my car (currently in the shop due to the HV battery recall). my only issues were:
1) skewed 360º camera view (fixed)
2) both tailgates not opening/closing with buttons (fixed)
3) random phantom switches to hybrid drive mode (rare but ongoing)
4) HV battery recall (ongoing). truth be told, i didn't have any issues with electric performance whatsoever (charging, driving, etc). while my car was getting the tailgates fixed, my VIN popped up with the recall, so they kept it.

still, no regrets.

Yesterday was my first full day of mixed driving with the 45e. Drove about 70 miles in urban and suburban areas. Battery was depleted for the last 20 miles, and the car returned 38 mpgs at the end of the day.

Up to the last 20 miles, using just hybrid mode, car was returning 50 mpg.

I later found out the area I was in had very cheap charging, but my phone was dead. The BMW idrive point of interests only show evgo locations, which are very expensive.

Still way better than any 5000 lbs car out there. My X5d would have returned max 21 MPGs from similar driving, but more likely 19.

Yeah, no regrets

I'm getting over 800 kilometers (500 miles), but thanks to our speed limits, my average speed is below 100 km/h (62 miles). Roads are not flat, height varies from 2 meters (6 ft) above sea level to almost 600 meters (almost 2000 ft).

[jad03060]

For a vehicle this heavy, I'm surprised and pleased that it is as efficient as it is. And, for those that love their V8, yes, I could have had one of those, but for my use case, lots of short trips (retired, and live close to most normal needs of food, shopping), it made no sense as those types of trips are hell on an ICE.

Had about 28-mpg on a trip from NH to MI (over 2000-miles) and back with little opportunity to recharge. While there was some local travel, at my destination, not that much, so most of this was interstate driving.

it should be noted the 45e gross vehicle weight that includes passengers/cargo is almost 7000lbs and makes its efficiency even more impressive!

Here's what I got on such a trip 2 weeks after I picked up my 45e in January. 23mpg. After breaking it in, 25mpg on similar trip.

I'm on a road trip currently. Highway speeds 75-80 mph, average consumption is 29 mpg if car doesn't charge the battery. Ones I switch to charging, it drops to 15-17. Economically it literally makes no sense based on the gas price vs electric mileage I will get.

If you want some battery capacity when you get to your destination, turn battery hold on BEFORE your charge level drops to that point. Maintaining it is much more efficient than trying to recharge it. On a longer trip when you need/want some battery capacity after you get there, it makes sense.

I use 30% which gives me enough to precondition and keep the cabin comfortable during a rest stop, if needed. Used in that manner on a 2000-mile trip in August, I averaged 28mpg.

I posted this in another thread already but today I went to a SoCal dealer to test drive a 45e and there was none. They are selling them 7-8k above msrp, which makes the math less favorable and essentially cancels out the federal tax incentive. I will of course reach out to other dealers but it seems like my goal of getting 5-7% below msrp before incentives and federal credit is not going to happen. Anybody have similar experiences?

welcome to the forum. no need to double post. your inquiry is better served in the pricing and ordering subforum. i already replied to you in the other thread.

I don't understand why in sport/hybrid/adaptive modes on cruise control and speeds of 70-80 mpg when only ICE is running, the battery charge is dropping slowly. Makes no sense.


When the battery is empty, car automatically recharge it to 3+4 miles and keeps this way in any mode. That should be enough for precondition.

I can’t believe this thread is still going. I’m very grateful. I started it a long time ago when I was on the fence about getting a 45e. No dealers within 300 miles had any to test drive so I had to order one without ever driving it. After 7 months and 11000 miles I must say this is best vehicle I have owned. Comfort, utility, performance, style….and yes the gas mileage. For me the biggest value is that there is no sacrifice in performance (for me anyway) and at the same time the dependence on gas drops substantially. In fact I wouldn’t care if it were MORE expensive to own this thing over a 40i….but it isn’t.
