Exclamation Would you consider a hybrid 4 cylinder M340i?

BMW just sent me a survey asking me this same question. They wanted to know if I would consider a 4 cylinder M340i f the inline 6 were no longer available. Of course I said no, I would look elsewhere for another 6 cylinder car.

Next was whether I would consider a hybrid 4 cylinder that would offer the same acceleration as the M340i while giving superior MPG. Again I chose "No".

Feels like they're looking to follow Mercedes in the future, so most likely the G20 maybe the last fully GAS car. That would really suck. Feel free to share your opinions/dissent etc.

Cheers!

No. No. And a thousand times no. I recognize that it's not the only great engine they have, but to me the inline-6 is the heart and soul of BMW. It was rough enough when it went turbo charged, but to lose it entirely? Not good.

Unfortunately, this question is going to keep popping up. Just as Mercedes may be dropping the V8 from the next C63, I fear this conversation won't be resolved so quickly, especially outside the US.

Definitely not interested in the M340i with a hybrid 4 cyl... To me it's not all about the 0-60 times, etc. I ordered the M340i for the inline 6, not just the performance from that engine. Even though the exhaust doesn't sound as good as some of the naturally aspirated 6 cylinder engines, it certainly sounds better than a hybrid 4 cyl would. Will be a shame if BMW starts going the way of Mercedes...

I wouldn't be interested in that. I can already get that, that's nothing else than the 330e with a stage 1 tune, maybe a bigger turbo.

However, I wouldn't mind a M340i with the electric motor on top. So basically a M345e/M350e. I'm pretty sure the instant torque can hide the extra weight from the battery well and will also (maybe, depending on the kind of driving) offer better fuel efficiency.

As long as they keep the I6, I actually wouldn't mind a hybrid M3. Of course with reduced battery size, something like 5kWh which will be good for single digit miles on electric only and adds under 100 pounds of weight.

Yeah I wouldn't mind a hybrid 6 cylinder (aren't they putting one in the M440i?). But I'm not sure I'm willing to give up the I6 for a 4 cylinder, that's just asking for too much.

The B58 is such a great engine, puts a smile on my face just thinking about it. But looking at this survey, I think the writing is on the wall for the next gen M340i... maybe even the LCI.

Just a mild hybrid in form of a Crankshaft-Mounted Integrated Starter Generator, it only adds a negligible amount of hp (like 11 iirc?). You do get a small boost in torque, but nothing substantial. The ISG will crank the engine to 1k rpm, so it turns on faster and with less vibration compared to a conventional starter. It also allows to turn off the engine while cruising (gliding) and completely decoupling it from the driveshaft to also cut out any engine drag, and thus gets like 1 or 2 more mpg.

I would like to see a powerful motor integrated into the drive train, like 200hp+ electric only.

Hybrid? Short answer is, No.

Full Electric M340?, YES!

I have not looked too much into the i4, TBH. My next daily will be electric for sure.

I have a 530e and love it. But I would prefer one with a straight six to go with the electric motor. The 545e is supposed to be that and I was thinking of upgrading to it BUT Arizona has now killed the car pool lane for everyone with hybrids but it did grandfather those of us who have already qualified. So I will probably stick with my 530e.

So...for me...I do like the phev but with a six, not a four.

At that point I'd rather get an electric car. Not interested in 4-cylinder BMW's, the straight-six is one aspect of the brand that I will and have always loved.

Interesting. I'd also be against a 4 banger in the M340i, woulda bought the 330 if I wanted better MPG etc.

Funny enough, BMW's design team called me the other week and asked me for specific feed back on my current M340i and what I thought about the overall design language they're incorporating in their new generation vehicles.

I gave them a ton of feedback and we talked for about 20 mins. Did anybody else receive a similar call recently?

Hybrid 4? Nah.

Hybrid 6 putting out somewhere in the neighborhood of 400 hp from the ICE and another 100-200 from Electric, with the ability to tool around in electric-only mode for quick grocery runs? I'm down.

The reason I didn't get a 330e is that, although it is badged '330', it performs like a 320i - not a 330i - when the electric motor is not in use. That seemed like a bit of an odd choice to me, but I suppose that because economy/efficiency is a major goal it makes some sense.

It's probably all irrelevant anyway. When a large corporation does a survey it is normally to validate a decision that's already been made and assess if it will affect their bottom line.

All these cars are more than fast enough - I got the M340i for the sound. So, if the choices were the current 330e and this mythical M340i four cylinder hybrid, I'd just get the 330e.

If they took a 330e and upgraded it to a ~300hp I4, it'd probably perform like an M340i or better, but it still isn't the same. I'm sure this is the direction we're eventually going, but for me, once that sound is gone, these cars will just be appliances.

I have a 330e and cannot drive it in engine only mode, the battery is always on and full power available, even with the reserve when it has low charge. It has plenty power and a 320 cannot look at it. Funnily enough it can do electric only obviously.

But you are right, it is irrelevant.

Not quite true. BMW saves approximately 20% of the battery capacity to save the life of the battery and to provide boost. So when the battery gauge shows "0" or "---" there is still battery life for boost. I have often run the battery down but never lost boost.

Even a crappy econobox can cruise on a highway. It is the need for sudden boost that makes the difference and you still have that with the BMW phevs.

But having said that, there are many, many cars out there and everyone should procure what works for them.

The design and life of the I6/V8 depends on future emissions legislation in Europe and China. NA PM1 starts in 2025. The current engines in production B58TU and N63TU3 are quite impressive in regards to FE and Emissions. I'm sure BMW has a few additional tricks up their sleeve to extend the life of these engines as they continue to fund the electrification future. I hope the survey convinces leadership to continue to fund revisions.
