Hi
I can’t seem to find the actual bhp split on the 50e compared to 45e.

I have had car about 2 months and haven’t been any where too far, but motoring press and BMW, info inconsistant?

[TurtleBoy]

ICE is 308hp and the electric motor is 194hp for a combined 483hp.

Thanks, so once battery gone it’s a de tuned 40i!

Nope. It always has some battery in reserve. Even though it says zero range.

Phew ! On longer journeys I was worried

Stupid question.
But why does a+b != c ?

This is peak hp number, and peak HP of ICE happens at different rpm than that of e motor.

I notice mine aggressively adds miles back to the battery once it’s down to zero. Seems to use regen more than coasting and also if you happen to be in sport I think it’s tapping power at times to directly charge the battery. The miles seem to add in quicker in Sport mode over Hybrid.

I have not noticed any power reduction at 0 miles remaining, all driving performance has remained the same, at least in my driving. However, things like pre-condition are definitely not available at that point.

this is not true. “reserve” denotes an ability to be utilized if needed. once the usable capacity is used up, that’s it… but don’t worry. once the vehicle sees this, it will begin to charge the battery and maintain a minimum charge so the electric motor can assist the ICE as needed.

that being said, once the electric range reads “0”, the usable capacity isn’t completely used up right at that moment. this is evidenced by the fact the vehicle continues to operate electrically for a little longer (NO, this isn’t a reserve). after that, it switches to Hybrid mode and the ICE fires up.

there are reports of owners losing the electric hp side while driving which resulted in noticeable loss of power. you won’t (shouldn’t) experience this loss during normal driving/cruising because certain conditions have to line up perfectly for this to occur, such as using up all usable capacity while towing a trailer up a steep mountainside. (one guy reported this in the FB group.)

Can anyone check max boost at WOT on 40i ? Would like to see the difference. 50E is 10psi

Yeah and is the B58, the same as in 40i models and they simply restricted boost? I can't find any technical info on the drivetrain. Does it have the same turbo as 40i models? If so, obviously there is a lot of untapped performance at hand.

Ok. Semantics. I wish I could find some more technical information in the car. Bmw is vague.

I’ve read similar comments to this a few times and it’s hard to comprehend as it appears to be this mythical impossible to reach state of using all electric power. Where shouldn’t this be a bit more formulaic. instead it’s you will deplete battery in - 50mph headswinds while puling a 5000lb trailing on a 30 degree incline… seems odd that it’s not more well defined…

I’m not a 50e owner. My wife has a JGC hybrid and 100% will be riding ICE only shortly after using all electric. Yes when you brake into a stop light you will then get your next 50 feet on electric but then cuts over to ice. After that, If I need to accelerate it’s all ICE and it’s complete dog shit 4cyl. While I know bmw is far better I still am a skeptic…

Let’s throw an example… For the 50e. If I’m on the highway let’s just say autobahn.

Full Regen braking off.
Battery 100% depleted.

I floor it to go from 60 to 150mph.

I have to think there battery power won’t be there helping to the full 150 or for very long at all…. Am I wrong?

The car will charge the battery use the ice directly and try to maintain it to ~5-10% / 2-4 miles in sport and battery save mode respectively, so regen on or off does not make a difference, there is always power in battery to help.

If you intentionally deplete the battery in EV mode then yea you expect not much help from the electric motor .

It is like asking “I intentionally deplete the car 12v battery by leaving all lights on all night, can I expect my car to be started?” Answer is no but it’s kind of not something that normally happens

in this scenario, you’re likely not wrong, but
1) it’s not designed to be a track vehicle
2) during everyday driving, you won’t be without the assistance of the electric motor (only in rare conditions would the ICE be completely isolated from the electric motor. BMW PHEV design does a good job in preventing that from happening, but as I illustrated earlier, it can happen. another scenario where it has happened is after the vehicle has sat overnight in extreme freezing temps. upon initial start, owners received notification the electric motor is offline because the battery is too cold. after a few minutes drive, it’s warms up and the electric motor comes online again.)

Oh that’s interesting. It will use the motor itself to regenerate a minimum charge % in sport mode? That just costs you gas? If I’m understanding that correctly that’s very cool.

Yes. It is not officially stated anywhere but observed by many forum members. About 2 miles for sports mode and 4 miles for battery hold mode.

Thank you for this.

I think some people wanting hybrids who often travel more than the range are hesitant as they don’t know the type of car we will get when the battery is 0.

The most common answer is don’t worry about it it will never happen which is not true. It’s not what the car was designed for but it does kinda stink if you just get off a 60mile highway run and you want to let it rip on a few back roads - that near 500hp car you bought wont really be there for all of it…

Helpful to be able to always have some amt on tap

[eluded]

No, it will still have the HV system to add some horses. I wish I could find good documentation on the differences between this motor and the B58 in the new 40i. I've watched videos where they claim some parts are upgraded to withstand being abused when not at peak temps. I assume this is why the motor is "detuned", ready for cold motor abuse.

Which part in an engine can be upgraded to better withstand cold abuse? Please educate me.

Almost certainly you'll still be able to enjoy all 483hp after a 60 mile highway cruise, or even a 200 mile highway cruise, on those back roads.

It's easy to think in black and white when it comes to a PHEV's operation, but there's a lot of intelligence built into the system so *both* engines are available to propel the car in nearly all circumstances.

Even when the battery range has shown "---" on my 45e and 50e, I've yet to experience a situation where only the ICE moves the car when the pedal is pressed to the floor. It's a very smart system.
