    Auto Express: The next flagship BMW 3 Series will be powered by an amazing 450bhp tri-turbo engine

    http://www.autoexpress.co.uk/news/au..._car_boom.html


    They say the next M3 will get a 3.3 liter tri turbo engine. Here is the article from Auto Express.


    Get ready for a boom in M cars. The boss of BMW’s M Division, Dr Friedrich Nitschke, has confirmed that a raft of new models wearing the famous badge is on the way – with the M2 to be joined by a powerful M3 and a successor to the M1 supercar.

    “Our pace of development must accelerate,” he told Auto Express in an exclusive interview. “We can build more cars, and we can build a wider range of cars.”

    The new flagship 3 Series is due in 2014, and will feature a fresh 3.3-litre six-cylinder engine. This is set to get three turbos – one powered by electricity, rather than the exhaust gases – and is rumoured to offer 450bhp. A mix of steel and ultra-light carbon fibre-reinforced plastic in the body will help deliver huge pace.

    But as Nitschke revealed, the car will also be efficient. “There will be a bigger focus on very low fuel consumption,” he said. “The new M3 will prove this.” However, this more eco-friendly approach won’t dilute the M Division’s high-performance appeal – as a replacement for the M1 supercar is finally coming close to reality.

    This has been on the drawing board for more than 11 years, but only now does technology allow it to deliver the pace drivers would demand. “We have a fantastic history with the M1,” Dr Nitschke said. “The decision on developing this car is open. We’d love to do it.”

    There’s no word on engines – but it would need a V10 or V12 to compete with rivals from Aston Martin, Lamborghini and Ferrari. If the project gets the green light, it’s unlikely to arrive before 2016.

    The company is also looking at a successor to the ‘breadvan’ – the Nineties Z3M Coupé. “There’s no decision on an M version of the Z4,” added Dr Nitschke, “but this is something we could do easily.”

    In addition, he spelled out a keenness for the M Division to “increase the speed with which we launch new models”. A lighter ‘CSL’ version of the new 1 Series M Coupé (tested on Page 56) is on the cards, which could take cues from 2007’s tii concept.

    Um, if one of the turbos is powered by electricity rather than exhaust gases, that makes it a centrifugal supercharger, not a turbo, since it will not actually have a turbine section.

    Hmmm, looks like this is confirmed.

    Good job, this will be our lead article for tomorrow once I put up the summary and find a good pic of a tri-turbo motor to use for people to get an idea.

    Stories like these can make you angry because the automakers have had the technology to create vastly more efficient vehicles for such a long time...

    Also the so-called bpost bmw insider claims there will a X3M. It will have this engine prior to the M3 release.

    He has a new thread with some interesting details. Including X1M and M2 info.

    Not at all, care about power potential not MPG. This thing won't be able to compete with larger displacement boosted motors it's just cool for BMW from a "green" standpoint.

    X1 M is just really dumb $#@!. X3 M I understand, and will defend as it makes more sense than an X5 M but what on earth is the purpose of an X1 M?

    I knew the 1M would be the beginning of the M badge on everything, damn it.

    I think they are on the way to having a M version of every model. Just crazy.

    If done right, the X3M could be the perfect suv.

    Efficiency generates more power vs heat. It is good for everybody.

    Big engines can be more efficient than small ones.

    I hope they will get above 50% efficiency. It would mean weight savings in engine and fuel amonts and lower temps without heavy cooling equipment.

    Looks like the new M3 will be the real game changer. It will run circles around the competition in the Ring.

    Volumetric or thermal efficiency maybe. MPG doesn't produce more power, usually the opposite as more power needs more fuel.

    Big engines can be but smaller engines usually are.

    3.3 liter triple turbo inline 6 cylinder confirmed for next generation F30 M3 - Motor to possibly power X3 M as well

    Looks like those triple turbo rumors 6 cylinder rumors for the X3 M were true. Auto Express reports they confirmed the triple turbo 3.3 liter with head of M Dr. Nitschke. 450 horsepower is the expected output with 2 turbos fed by gasoline and 1 that is electric. How would this work? We aren't entirely sure how BMW plans to arrange them but the attached diagram may help resolve how the turbos could be positioned with an inline 6 with the electric turbo in the middle working as a sort of quasi-compound turbo setup.

    it's actually a twin charged, one supercharger+ 2 turbos.

    only 36hp more over S65? that's not even as powerful as current C63. they better make it much much lighter than E92.

    also the 3.3liter displacement sounds like a V6 based on S63, if so you are screwed BMW.

    Sorry, where did you hear twin charged? Tri-turbo is reported as confirmed.

    This I agree with. By locking themselves into a 6 cylinder BMW has painted themselves into a corner.

    Just forget MPG for a while, as other readers might not be that interested in it Click here to enlarge

    Wärtsilä's latest engine achieves 50% efficiency, i.e. it generates a lot of power (50%) vs heat compared to the typical 30-40% efficiency ratings of car sized engines which are small since they need to fit in a car... So, big engines seem to be more efficient Click here to enlarge

    If BMW would be able to increase the efficiency of a given engine, it means more power! or alternatively lower fuel consumption, in practice it means both as they want to enhance in both fronts.

    That seems to be inline-6 in the pic. Inline 6 is the best layout for twincharging and the third charger after the twins makes this combo even better.

    This layout would mean a huge increase in the area under the curve when compared to S65.

    You see the twins connected to the two 3-1 exhaust manifolds, the third charger is different from the twins. Big brother?

    there is no such a thing as Electric turbo, the third blower is a electric supercharger.

    Those are three turbos, no supercharger involved.

    does the third turbo use exhaust gas to spool?
