M5 [Official] The BMW Concept M5

[Sunny]

Mmmm - nice find! Notice how they leave plumbing from the turbos to the charge coolers and the actual coolers themselves uncovered - unlike that done on the X5/6M where the whole lot is covered over by a plastic camping table from the back of the engine bay to the front.

Also, the piping into the charge coolers is much fatter, the connection to the charge coolers looks much tougher and more robust and the coolers are a fair deal bigger too. More power than the X5/6M? Has to be for all that difference.

That's a damn mean looking engine bay!

Yea, the intercooler and the piping looks much bigger and more heavy duty compared to S63 in X5/6 M.

As for exposed parts, might be cause it still a test car, I won't be surprised if they hide it all under ugly plastic in the production version.

 

[klier]

Definitely ugly plastic covers on the final production car. The covers are missing for testing and easy access...

Engine looks like it means business

 

[Centurion]

What an engine bay. Those 8 cylinders will breath air like a rhino. I look forward to technical comparisons between the F10 M5 engine and the Ricardo built McLaren M838T which is also Turbo charged though only 3.8L small, it outputs 590hp.

So.... who now wants to complain that this is just a warmed-over 550i motor, and that M just half-arsed this?

Betty probably
As he as done so since the very beginning

Another interesting feature and something different from the X5/6 M unit, there seems to be a direct connection between the turbo inlet to the intercooler inlet, bypassing the turbo. Wonder why? Martin?

 

[Zafiro]

I wonder how much the engine weight is. Lighter than the V10?

Haha, that was a good one.

 

[tikipukapuko]

wow,that looks like some bulldozer engine fitted in a car

 

[DblPen]

sorry for being off topic,but any1 knows when alpina is going to introduce alpina b5 s? maybe about the same time as new m5? :?

Hi Sunny,

I had a good look at the picture and then compared back to that of the N/S63 pics. The basic plumbing design and flow is the same for the new M5 engine and that on the N/S63.

The pic is misleading for two reasons:
- The turbo inlet passes underneath the intercooler hose and makes a dogleg to the actual inlet.
- There is an odd-looking component (that looks to be a blow-off or dump valve but I am still trying to find out) on the intercooler hose that makes it appear the there is a connection to the inlet pipe coming from the air filter box.

 

[klier]

Dump valve on an M5 will make people think a Subaru Impreza is passing them will sound bloody cool though.

Both the Alpina B5 and B5 Touring are now available.
If you mean for the North American market? They will not be imported because of the close proximity of price and segment to the M5.

Usually, Alpina introduces the 'S' model designation shortly after BMW brings the LCI of the base-model to the market.

True in parts. Mainly due to the limited output figures @ Alpina and the cost factor for homologating a car for the U.S. and making it DOT-compliant. And of course, last but not least, BMW's veto power on allowing Alpina into niches and markets.

I don't see anything yet to change my opinion. All I see is a few pics of what looks like a VERY IMPRESSIVE engine bay. It's still going to be a 4.4 litre twin-turbo V8.......which is exactly what is in the 550i. It's still less of a difference than what existed between the E60 M5 and 550i. A completely unqiue V10 compared to a V8. So, nothing has changed I'm afraid.

 

[martinbo]

Nah, c'mon Betty. Simply dismissing the "specialness" of an engine based on layout commonality with a lesser model would be a touch glib don't you think? I think the old S54 straight six is one of the greatest engines ever made but on the face of it, it was only a 240 cc bigger version of the M54 in the 330i. But us gasheads - we know different... we know about the vast inlet plenum, the individual throttle bodies per cylinder, the forged pistons and sintered conrods, the high internal piston speeds and, until the advent of the GT3 RS and 458, the highest specific Nm per litre for a naturally aspirated production engine.

One just has to take a look at this engine's plumbing to appreciate that BMW haven't just gone and done a copy & paste job - mind that we still have no idea about the composition or construction of engine interals - in installing the most powerful engine ever in the BMW M5.

If turbocharging is the way of the world then I can already state with confidence that this is one of the most special turbo'd engines I've ever seen. Let's just hope that the reliability of the power delivery is as impressive as its physical arrangement. [Limp-mode, hell no we won't go...]

 

[Betty Swollocks]

I agree Martin. The 1M seems a lot more special than I expected it to be and I changed my opinion of it over time and based on actual road tests and videos I saw, so may be the M5 will be different. However, I was responding to BeemerB773ER's and Klier's assertion that I should all of a sudden feel differently about the M5 due to seeing a few pictures.

nah, i meant alpina s model,with more performance

I don't expect you to change your opinion at all, as you've never done so. I was merely stating you would probably feel it is the same engine....
It's no biggie though. You're perfectly free to think the E46 330i and M3 are not the same base engine, and the F10 550i and M5 are. Or opposite. Or whatever.

I changed my opinion on the 1M Coupe, so what do you mean I've "never done so"? The 1M gets away with it because its a limited run, cheap entry model, so I can see the economics behind it. The M3 and M5 are the flagship M models.

I don't give a toss whether the E46 M3 and 330i had basically the same engine. The E92 M3 and E60 M5 had unique engines, so I see the F10 M5 as a step backwards!
