Next BMW M3 to get triple-turbo six — Autoblog (http://www.autoblog.com/2011/07/07/next-bmw-m3-to-get-triple-turbo-six/?utm_source=twitterfeed&utm_medium=twitter&utm_campaign=Feed%3A+weblogsinc%2Fautoblog+%28Auto blog%29)

The BMW M3 has grown cylinders over the years like a pubescent pre-teen grows in height. What started out with an inline-four then grew into a straight-six for two generations before packing a V8 into the current model. The next one is expected to set to drop a couple of combustion chambers and go back to a single bank, but don't think for one minute that'll mean a drop in performance.

According to the rumormongers at AutoExpress, the next-generation M3, due sometime around 2014 after the new 3 Series comes along, will pack – wait for it – a triple-turbo straight-six. The innovative arrangement will reportedly include two conventional spools powered off exhaust gases and a third electric turbocharger. Total output could be around 450 horsepower – a bump over the current V8 model's 414 hp – with even more carbon fiber bits than the CRT edition pictured above to help keep weight down.

Not exciting enough? BMW's M division has plenty more in the cards, potentially including an oft-rumored new M1 supercar and, once the 1 Series M Coupe is done its production run, a lightweight CSL version. An M version of the Z4 is also under consideration, but of course nothing final until the cars make their debuts


wow triple turbo..

I like the "bigger is better" methodology. Should do a v8 with twinturbos. That would be hot

V8 does have twin turbos.. one on each bank?

With the advanced of material sciences and the wider availability of inconel. Turbos lasts much longer, most importantly lighter. It makes spool ups much quicker.

The current gen m3 has a n/a v8

wow triple turbo..

whoa.... double turbo all the way across the bay..omg wow whooaaaa OMG OMMG! ooohhhhhh i think its turning into a triple turbo.

what does this mean?

LOL first thing I thought of:

then the M3 will be no different than the m5/m6

M6 has a 5.0L v10

the newest M5 is gonna run a 4.4 twin turbo V8...

i bet the upcoming M6 is gonna run the same engine...

so?

im still not use to the newer m3 look still liking the older models

so it's not a twin turbo v8

heleu

Isn't an electric turbocharger...just a supercharger?

So it will have supercharging and turbocharging. VW has a 1.4L Twincharged engine just like that now.

Next m5 rendition will be a "wussy" v8:) oh man, the notes from that v10.....

With the advanced of material sciences and the wider availability of inconel. Turbos lasts much longer, most importantly lighter. It makes spool ups much quicker.

Correction: With the advancements in metallurgy, inconel is old school. Titanium-aluminide or TiAl is probably what you are thinking of. Another way to reduce weight is with a billet compressor wheel. I weighed my cast gt28 comp wheel vs my gt28 billet wheel and the billet wheel is 20% lighter. This is on a small turbo.

doesn't turbo cost a lot to replace?

What's with the ridiculous comments on this thread? Looks like a GTR thread.

Sure they can be expensive, why do you ask?
You don't replace the Turbos with the engine oil

No. BV50G, the turbo unit used in the 997 Turbo is still uses inconel/ nickel for the high temperature components. The advancement is the lowering of cost of the nickel based components. However it is still too expensive to craft a turbo that can with stand 1000C for cars cheaper than that. The lightening up is also due to better / more reliable sensors so they can use electronics for the variable geometry.

You stated inconel was lighter and spools quicker which is not true. Then you changed it to nickel. It's nothing special, there are millions of vehicles with inconel turbine wheels. Mechanical or electronic vgt actuation makes no difference on the rotating assembly weight. The only difference mechanical or electrical will have is on spool time is because the electronics will allow more parameters for feedback for better tuning.

I am not sure what the testing requirements are for gasoline vgt systems like on that 997 but I have seen diesel vgt turbos operate on the test stand at work over 2000F.

+1

E46 M3 is still the best all around IMO

ok bill nile the science guy..dam.


on another note...bmw does it again *clap clap clap*

Inconel is a trade name for nickel based alloy, much like Panadol is trade name for acetaminophen. There are might millions of inconel turbine wheels for diesel.. but not for gasoline engine it is still very relatively rare.

It doesn't make much of a difference in rotating assembling, but it makes a lot of difference in complexity and reliability.. also the final system weight.. eg you don't need a wastegate and a more compact packinging... things that Porsche cares.

To make spool faster is the lower the PSI.. make the whole thing smaller.. yes it has nothing to do with the nickel, but if you look again what I wrote, I didn't say that.

Which other turbo that can handle 2000F as you mention that is commercially available and for gasoline engine?

My work makes ~1000 turbos per month and sells more. All inconel wheels friction welded to 4140 shafts. Used on gasoline and diesel engines.

Most failures are oil related, or ait filter related.

Holset 351ve vgt most commonly found on the 6.7L cummins has been used on gas applications (not by oem).

I think we are talking apples and oranges. I'm just saying that inconel is not new to turbos or rare. Maybe in the vgt/vnt system it may be but not turbine wheels.
