    The new b series motors replace the n's.

    The 335 will have more power as well...
    I know Mini is using these and the BMW platforms based on them but I don't know if this is going to replace the whole N engine lineup. We'll see but regardless the N20 is stronger at the moment.

    It is hard to believe but I think this is where BMW's lightweight technology comes in.

    The articles say the N platform is done. The B engines will be more powerful and till take over the whole lineup eventually.

    I don't think it's correct as the N platform has plenty of life in it considering it uses four cylinders, V8's, inline-6's, etc.

    Ok but I see nothing about the N63 or S63 so how is the N line being replaced?

    Its just the beginning... thats the point. You pick one N engine and act like the "N line" isn't being replaced? It is... I'm sure they will announce that replacement too. The S engines aren't being touched as far as i know. So the N20 had a run of 2 years...strange imo. I don't get why bmw is changing to the B series engines so quickly. They are also calling the car a 340 instead of a 335, and 440... etc.

    The N line is a long list of motors. You act like they are all about to be gone, they aren't.

    What are they going to replace the V8 with?

    The S engine is based on the N engine anyway.

    BMW does odd things but like I already stated engine families have gone on for long times with modifications. Is the B-Series a ground up design anyway? I haven't really looked into it.

    Who knows what they will replace the v8 with. The B series seems to be a replacement for N and will eventually replace them all. Here is a quote from a article in auto evolution.com, I posted earlier.... "Well, the F30 platform will turn 3 next year and a deserved LCI is on schedule, as usual. The facelift, however, will not only focus on exterior design changes but it will also introduce a lot of new technology and, according to a BMW insider, a brand new set of engines.

    These new units will be wearing the B codename, replacing the N engine family completely. Were already seeing these units introduced today, on cars like the new Cooper S and the Active Tourer but, for now, the 3 Series range will continue using the N20 and N55 petrol versions.

    The B48 and B58 engines will be used on the new 320i and 335i, with an obvious power increase. Most likely, the 320i will have 192 HP and 300 Nm of torque, more than the 184 and 270 Nm of todays model. As for the 335i expect it to go up to around 340 HP and 500 Nm of torque, as the same engine will be used on the LCI M235i later on."

    I see what you are posting but once again I don't see anything about an N63 replacement any time soon. There also are a couple other N motors that won't be getting replaced soon...

    Come on man the entire N-Series can't be replaced by what you showed.

    I get it that new motors are coming but the N-Series is pretty diverse.

    no i'm saying they will make other b series engines that have similar power/displacement as the V8's that will replace the n63 and n74, i'm not saying what I showed will replace them. What I showed is a example of the n series engines going by the wayside

    Some N engines are being replaced, ok. Some aren't.

    They all are ... your wrong, admit it. God damn you love to argue. You originally said the n55 wasnt, then the n20, both are...then you grasped and found the n63 wasn't mentioned in the replacement.... Maybe the V8 is replaced next year, but its coming.....

    I'm not arguing I'm pointing out the N motor diversity is pretty big and what you showed me had nothing to do with replacing the V8's or V12.

    Ok, so they want the Mini B-series architecture to be cheaper, and? We don't know what will happen with the N20 architecture or the other N motors just yet.

    Additionally, you are wrong about BMW quickly replacing motors as pointed out some engine families stay around for more than a decade. Let's just wait and see although yes we obviously know more B-Series motors are coming.

    Like which ones?

    Take the N series. There are almost no interchangeable parts between the N20, N26, N52, N54 and N55. Each N5x engine has a unique block, head and pistons from the other in the "series." They only thing they share is the basic combustion chamber configuration and the initial letter N in each engines series name. Other than that, each N5x engine is a vastly different engine. The N20 and N26 differences I am not well versed about.

    Same for the S series, but even more so.

    The N54 and N55 are pretty similar designs. They're the same basic architecture I'm not sure how the block differs if it even does? Bore x stroke is the same as well.

    Regarding other motors you have the N63, N63TU, N73, N74, etc. The N74 replacing the N73 which itself replaced the M73 and they all have the same basic architecture.

    Next gen Z4 will be available initially with non-hybrid turbo 6-cylinder. So rwd as well.



    AutoMotor und Sport is reporting that new next Z4/Toyota project WILL have a turbo six gasoline engine.

    BMW spokesman Kai Lichte said:

    Whether the hybrid powertrain is also used in the BMW, or whether the Z4 gets four-wheel drive, but it was "too early to talk about it," as the BMW spokesman told an Australian newspaper says. "First, we will have a six-cylinder, that's for sure. Everything else comes later maybe."
