It has not been yet confirmed with multiple sources, but the rumor mill has it that BMW is developing a tri-turbo diesel engine based on the six-cylinder turbo existing in the BMW line-up. The tri-turbo engine will output 354 horsepower and it will be initially used in a BMW X5 Performance Diesel.

This new engine will carry the EfficientDynamics badge by incorporating technologies like Start-Stop system and Brake Energy Regeneration (KERS). It will be geared towards the European market in need for a top X5 model.

Rumor: BMW X5 to use the first Tri Turbo Diesel engine

BMW X5 Performance Diesel has less pronounced wheel arches that the ones seen on the new BMW X5 M . The Wheels give the car very sporting and powerful appearance. The aerodynamic performance package follows the design of the X5 M,  but the central intake is smaller with the intakes for the brakes less open mouthed and a colored bar across .

Same source, someone close to BMW, speaks of subtle spoilers for air flow at the leading edge of the bumper. The rear of the car features two larger and more exposed performance exhaust pipes which will be incorporated in the upcoming facelift of the X5.

The tri-turbo engine will be first available in the X5 models and the X6 at a later date. BMW plans to introduce the engine within key models such as the next 5 Series , 7 Series and eventually the additional 5er and 6er variants.

It is unknown what name will these X5 models carry, but as soon as we get more info, you’ll have it.

    Makes a lot more sense than the X5 M. I think they should have released this before the M but I fear the damage has already been done.

  • Mauro Corti

    What? 354 bhp? That sounds impossible to me. Many twin turbo engine had problems with turbo failure, imagine having 3 of them developing 354hp… mmh.. I think it’s just a number someone said, can’t be real

      Lol why?
      If u chip tune an 535d your can reach almost 400hp. and that’s with only 2 turbos.
      With 3 turbos you can get even higher.

  • Gord

    Hmm.. pretty soon we’ll see 4 turbos.

    Mad BMW. :)

    @Elio:

    Define; Damage. It’s a silly statement to make seeing that the car has just been introduced -no sales figures exist. If no body buys these cars -thats damage.

    What most people don’t realise, is that true BMW enthusiasts (the folks who’s upset by turbo and Xdrive M models, GTs and X6s) are reletively small in numbers. These folks are upset when BMW listen to a more wide audience and actually build cars that will sell in greater numbers.

    Don’t be upset by the changing times and demands, just be glad that BMW will continue existing because they sell cars.

    Any idea as to torque?

    Giom: Away from this site I’ve been reading a lot of comments from people about how releasing the X5 & X6 M is damaging the reputation of the brand. Whilst Audi are enjoying great success with the R8, BMW have spent millions developing two, 2.5 tonne monsters which, aren’t nearly as desirable.

    In the mean time they’ve cancelled more deserving M cars, such as the Z4 M. I can only think it was too late in development of the X5 & X6 M to cancel them.

    Sometimes you have to look at the wider picture, BMW may think they have a ‘Cayenne’ on their hands here but it could be damaging in the long run.

    this could be true….they need a stronger diesel , a tri turbo inline six or a V8….there was a V8 745d in a previous 7er….if true this thing will have well over 600Nm , in reality I think close to 800Nm….

  • Doug

    @Gord: Well, Horatiu did post that theory/rumor of a quad-turbo inline engine (4/6?) some time ago. This, if comes to pass subtantiates that thinking and direction.

    On the technical side, they must be having 2 cylinders on each turbo. Does that deliver consistent enough exhaust for a turbo to work efficiently? That would mean that there’s exhaust flow only 25% of the time, versus the ideal 100% of the time with 4 cylinders-per-turbo for a 4-stroke engine.

    But really, what is the point of triple turbos? It doesn’t give you any more boost than a single turbo, and the existing sequential TT design eliminated most lag. And there’s that reliability issue.

  • Doug

    PS: what’s the point of sequential turbos if the variable-geometry turbos eliminate lag, too? Why not have a single variable-vane turbo?

  • M

    Kinetic Energy Recovery Systems seems to be more appropriate for the acronym, KERS, rather than Brake Energy Regeneration, wouldn’t you say? =)

  • D Solomon

    All BMW has to do is make the CS Concept reality and multitude that version into 3and 5 series and the make Grand Turismo to kill the R8. Then, it will solve the problem with competitors. The engines of BMW has to continue to excel into longevity that it has in the past. Finally, after seeing the M X6 miniver around the track, I can imagine what is will do with twin turbo!!!

  • viper

    there are four turbos on a veyron…..wish BMW make a supercar on a bugatti level….

  • Doug

    @viper: That’s one turbo for each bank of 4 cylinders in the W16 engine, which is an understandable configuration.

    Why would you want BMW to build such a car? Because of its engine weight (necessary for the power to hit 250mph), it’s a poor car for a race course, which is where BMW excels.

  • Gord

    @Doug:

    Actually the Bugatti Veyron, while not as capable as other supercars, is still very respectable handling wise. It did a 1:18.X on the TG course, and while others cars can beat it, there are mainly stripped out track cars.

    And unlike those track cars, the Bugatti Veyron is also a civilised road car that is comfortable.

  • Doug

    @Gord: You’re right, it must be quite capable. I’m thinking of that Top Gear episode where they made the relative deficiencies of weight very clear by comparing it around the track to the much lighter Zonda.

    That’s insane. I would give it a few years before I tried it. You know how the new always has bugs.
