LCI upgrade next year.

[john-e89]

Im not sure if this has been discussed before so apologies if it has.

What are opinions on what the upgrade will be for apparently end of next year..? My thought is much the same as the E98, no bodywork or interior changes as such as not economical, so maybe some upgrades to the tech, but no idea what they could do in that respect. We've seen the car being tested on track so maybe some tweaks to the spring and damper rates or just software tweaks...? Personally I'd like to see some different colours available as the current choice is pretty limited and un-inspiring, i think a mineral grey and something wild for the outlandish look would be good.

Thoughts...?

Let’s hope there’s no 4 series snout and with the current chip shortages there will be less tech

The bit I’m pretty sure that will happed in lci is the 48v mild hybrid system. All other models of bmw have it so no reason G29 LCI won’t have. My G31 has the mht and I’ve checked the engine bay space in the G29 with the G31 as reference. The packaging of the mht components isn’t an issue at all.

However, since I’ve already had a bmw with the mht, I know how it will affect the car. My conclusion is that I’m happy to have it in the G31. But I don’t want it in the G29. It’s almost certain that the brake feel will be ruined by the mht.

Other than this, I heard the iDrive 8 won’t come to g29 due to the amount of redesigned components needed and with G29’s volume, it’s hard to justify the cost of those redesign.

Have to disagree with you there friend, there's no chance the Z4 will be a hybrid next year, far too much r&d costs for that on a low volume single platform. There may be an all electric Z4 in the future but for now another 3yrs maybe of ICE and that'll be it. Imho of course.

I don't know about this sort of stuff but I think it would there would be no structural changes but just maybe trim and seat colours and more paint and wheel options..

Let's see. Just to point out that mild-hybrid is not full hybrid as those 330e or 530e. What it need is simply a new generator/motor (2in1) to replace current alternator, a 48v battery which is the size of a shoe box (let's be precise, my uk size 8 shoe box is bigger than the battery), and a DC-DC converter which is the same size as the current B58 ECU if you've seen it. Because its simplicity, that's why manufacturers are keen to implement it in their car to get a better CO2 rating with almost zero upfront R&D cost compared to plug-in hybrid.

If you are interested, I can share some photos of all the components of a 48v mild-hybrid system in my G31.

That's pretty much it I think Nige apart from some suspension tweaks.

I take your point but I don't think even that will be done due to even fairly low costs, the Z4 is simply too low volume and a single platform to warrant anything other than a few minor cosmetic enhancements and a bit of software tweaking. But as you say let's see.

Other than the MHT, I'm thinking whether BMW may bring the M340i/M440i engine (the higher output version of B58TU1 engine) to the G29. What I read somewhere is that when G29 was released, the higher output B58TU1 engine with OPF was not ready yet. Only B58TU1 without OPF was ready at that time. That's why regions like U.S get the higher output B58TU1 engine in G29 but we don't. Regardless of how minor change the LCI will be, it will certainly have a new type code for each model, which means new regulatory approval (type approval) must be carried out. Then, this brings back to the MHT. As the B58TU1 on the M340i etc. has already done the MHT integration, they may simply integrate the engine and send for approval. Don't forget nowadays, manufacturers are following what called modular platform concept, which basically means everything from the platform is inter-changable with only re-calibration work needed (in theory). Anyway, let's see.

Fair point about the modular platform, I had forgotten that I must admit.

One hand, I hope to have the higher output B58TU1 engine despite I think I rarely use all of 340ps (someone once said, engine power is just like the money in your bank account, you don't have to use it all but you will never think it's enough). On the other hand, I really don't want the MHT on my G29 based on my experience with my G31. So, either way, maybe BMW don't touch the engine at all during LCI is what I want. :headbang: :headbang:

They could bolt in the m4 engine in it. It would fit in no problem.

Let’s see what they do, but I suspect it will be an m40is with another 40 bhp “officially”

If I stick the 's' after my current m40i badge, can I unleash the extra 40 bhp "unofficially"? oke: oke:

Probably. . I believe there are some tests out there that show the m40i in U.K. spec producing more than 340.

That’s true. But US spec m40i also produces more than 380. :tumbleweed:

If you look at the E85 and E89 as previous LCI models then…

Engine tweaks and changes are often not connected to LCI

Technology boxes and associated configurations moved independently of LCI

So my guess is LCI will be paint, light clusters, marketing package configurations and M heritage accolades..

You may get minor engine re-map level changes , no transmission changes.

 

[KrusteKlubba]

The US version sounds better to me, looking at YT and Scott Smith BMW overview of the M40i with BMW Genius Lauren when she drives off at the end of the video.

 

[ori]

I think it’s just mapping because of emissions.

No one knows what the LCI will bring but even if they add the mild hybrid system it will add maybe 13-17 BHP.

Dealer doesn’t believe major changes will happen due to low numbers.

Also dealer said that missing spec on current production will be fixed with a software update which makes no sense to me at all.

 

[q96169we]

[ref]ori[/ref], mid output and top output B58TU1 engines have different cylinder head design and different compression ratio. The mid output in our m40i cylinder head is integrated exhaust manifold design and has higher compression ratio. This design will heat up faster when cold start than the separate exhause manifold cylinder head design in the top output engine. Also, the higher compression ratio will give better efficiency when the turbo is not fully kick in. The downside of both is that it can not handle higher exhaust temp and higher boost pressure. So, it's not a simple mapping difference.

Then, the MHT will produce 8kw and 35Nm max and the torque drops with engine rpm increase based on the data logged from my G31. However, this is not always available and can only last a very short amount of time.

 

[ori]

Slight misunderstanding.
I believe the engine setup on the eu cars and American cars is the same. It’s just a mapping difference.
Obviously the m4 engine has major differences.
