So those numbers on the back of Bimmers and Benzes should be disregarded from now on..

Hmm... yeah.  
Only Audi is the one that matches it's real engine displacement.

But they do put "V6T" on the Supercharged S4

Is there a "3.0T" on the back also? Or no such badge for the S / RS cars?

I don't think there is a displacement badge on S/RS cars, you're right. Only engine configuration V8, V10.

There is a '3.0T' on the back of the A6 though.

Turbo I4 Switchover Dates and Current 3-series, M3, and 1-series Production End Dates

On the heels of the big BMW turbo 4-cylinder (Specs/Info) news yesterday, SCOTT26 has provided (via his post) some dates for the switchover of certain BMW models from the current inline 6-cylinder to the new twinpower turbo I4 motor, as well as the end of production of the current 3-series, M3 and 1-series.

Here is the I4 switchover and end of production schedule:

    * E89 Z4 sDrive30i to switch to TwinPower I4 in September 2011
    * F10/F11 528i to switch to TwinPower I4 in September 2011
    * F25 X3 xDrive28i to switch to TwinPower I4 in 4th Quarter 2011
    * E81/E87 1 series to end production by August 2011 (new 1-series hatchback launched after Geneva - will herald complete petrol turbo-charged engine line up)
    * E82/E88 1 series to end production in 1st Quarter 2012
    * E90/E91 3 series and M3 to end production late 2011 or early 2012
    * E92/E93 3 series and M3 to end production sometime in 4th Quarter 2012

If this is to be believed, the 5 series will indeed see I4 later this year (that is MY 2012, I believe).

EDIT: Some additional information:

• the peak torque is reached at 1250rpm
• the minimum octane rating is 91 RON = the engine will run on regular

My initial reaction was "Oh no....."  (because I really like the naturally aspirated in-line 6)

But then I thought:
- more torque
- cheaper to run (and bonus on the fact it takes regular gas)

I think I'll end up liking it more.

^^ You forgot "easy to mod" 

You forgot lighter weight up front (maybe)

[tpl]

And.... maybe you could see the ground under the engine compartment... like cars used to be.

sadly no there will still be an undershield.  Oh well.

But again maybe with a L4 they will introduce a major technical innovation. A dipstick.  More likely they will seal the engine compartment apart from a little hatch for washer fluid, to keep the dirty germ ridden fingers of the demon customers away from the clockwork

Bye bye N52. I'm already getting nostalgic.

Might exacerbate the HPFP issues. :S

I'm not sure we'll see a 4 cyl 5 series in North America. People here associate less cylinders with less prestige. They'd rather have 6 cylinders making 200 hp than a 4 cylinder turbo making 300. That's why the Lexus IS250 has 6, even thought it's weaker than many 4 bangers. Same with the Infiniti G25. These companies understand the NA market better than BMW.

Personally I think they shoulda went with 5 cylinders.

[Triple Bob]

I4 Z4... Ewww

Oh, and you forgot the UK EVO FQ-400. 2L, 400bhp!

All the 28i cars will have the 4 cylinder in Europe, including the 528i. I agree that it will present an image problem for some buyers.

[tpl]

Should I ever buy another BMW I would definitely go for a 4 cyl Turbo  528 rather than a 230-240 bhp 530 6cyl or another 3-er.    But if they put the turbo 4 into a 328, that might be even better and in NA might get past the image thing.

[Triple Bob]

Personally I think the inline 6 is the best thing about BMW, it's the smoothest and most balanced engine layout, and the BMW ones are just fantastic. Beats a V6 or a V8 anyday IMHO.

[tpl]

I agree.     But I'd just as soon have a well designed turbo 4.  I transitioned from a 330 to the GTI and I think the GTI engine, in practice, is very nearly as smooth even if in theory it is not.

[Triple Bob]

Normally I'd agree with your usually sensible musing, not this time! LOL

Gotta agree, it's part of the BMW identity.  Love the wail of a nice inline 6.  Odd that they are getting rid of the I-6 in the cars, but they just put into production a 1.6 liter, 160hp inline 6 for a motorcycle.

Ooooohhhh nice!  Imagine that in a Caterham! 

[tpl]

I do agree that a 160 bhp inline 6 in a bike or a Caterham would be an earthshaking experience.  Although that new BMW turbo 4 would be as well.

And, Turbo, I only suggested that I, me, myself, would as soon have a turbo 4 BMW than a L6 atmospheric engine. Assuming that the 4 was cheaper and hopefully had a higher specific output than the 6.   I also agree that V6 engines are a bit nasty ( Dino 246 excepted) and I have never owned a V8.

[Triple Bob]

OK, you're vindicated!
