So what about the M5? does it gonna have a weight shaving ou a power increase? Please BMW stop the power war!!! Shave some weight, better drive a 1600kg 510hp car than a 1900kg 540hp truck...

I say BS. Even the diesel race engines from Audi and Peugot don't rev to even 7k afaik.

Love the copue-ish shape! Can't wait to see what this looks like!!

Agreed. Sounds more like the current M5 engine.

Whatever becomes of the M5 it more than likely will be very different from what we have today with all the world governments imposing strict C02 + fuel economy standards on automakers. What makes things even more interesting is that M has one of the most focused brand philosophy found anywhere, and that's has always meant building high revving naturally aspirated engines. With the alternatives to achieving better emissions and fuel economy they'll have to turn in another direction. Interesting indeed.

why the whole debate over a pointless babble by some ignorant barbarian from another forum?
M philosophy will not change, CO2 emissions until the foreseeable future are averaged out over the whole company range, economy is at the near bottom of the list for cars like these
who cares?
BMW is building an isetta something so it can keep building monstruously powerful V8, V10's and V12's that shame a ferrari if properly embodied, if the M5 turns diesel then every single other BMW is running on hydrogen,

These are the numbers for the actual V10, I am pretty sure of that.

Revving has no interest for a diesel, its construction makes that its power comes from the mid-range. And I see no reason for BMW to make its M5 diesel, really it makes no sense.

And there is no way a diesel suddenly could do 10,000rpm and 500+ hp when it is totally sci-fi today. You can't do such improvements so fast.
Furthermore neither Scott nor EnI heard about that...

Really, it is neither technically possible nor makes it sense to make a diesel M5. Unless, of course, BMW wants to kill both its M5 and its M-division.

If they wanted to do really sporty diesel, they would first make a lot of concept-cars around this, and they would begin with a 535 Sd, you see, or a 335 SEd, or something like that, a special sporty edition to make us accept the idea of a "race-diesel".

There is no way BMW would suddenly present the new M5 and oh surprise! it is a diesel. No way. It would be self-murdering to act like that without a massive preparation.

Look at the R8, noises since a year, concept-car, etc...and it is far from revving 10,000rpm. And the R8 is not only diesel, it is also petrol.

Furthermore, Audi does it because
1) they won Le Mans with diesel, and
2) they have to find their own way to distinguish themselves from Porsche, Mercedes, Lambo and Cie.

BMW is perfectly established with the M5, so they won't take any risk. And if they prepar a super-sporty-diesel it will not appear suddenly out of nowhere in the M5.

Exactly my point- just didn't want to state the obvious. Diesel engines to rev at the level will be some engineering marvel.

No M diesel in the near future.

But M engineers are experimenting. Playing with many interesting ideas. But it all boils down to marketing in the end.

So, when in the future diesel engines will earn a sporty performance image (especially in US market - largest single M market) perhaps M diesel will be offered. But right now BMW are not ready to take chances & possibly jeopardize M image.

Interesting isn`t it.
I always thought the front wheel position in the 5er was set a little too close to the cabin giving it a front-wheel drive look with it`s longer overhang. This next one is set further away with a shorter overhang, looking much more sporty.
