M7 vs. 760Li

[thepolarfoxqx]

Will there be an M7 - probably something like a performance version, the stock 6.0L V12 with all of it technology is tuned down to 66.7 hp/l, very low for a BMW engine, leaving plenty of room for more zoom. If a M7 comes out, it will probably be based on the short wheel base, and would need to make at least (minimum) 600hp to hold a HP advantage over M5, Perhaps if RS8 becomes solid reality (Like audi nuts are doing 4 wheel burnouts in front of their local bimmer dealers) then you will get either a M7 (600-650hp - nat asp - rwd - watch out! - or perhaps just a sport version - like the M5 4.6is. Either way, expect somewhere near 600hp, and of course 20inch rims. Who would buy a maybach when you could have M7 V12?

Keep in mind - as a small car company - BMW is reliant upon their suppliers for new technology. For an M7 to become reality, it needs a driveline. The M5 project will stew enough engine technology to cover that, but an manual would be innapropriate in such a large car, and so far there is no ZF 6 speed auto strong enough to take a 600hp car. I haven't heard rumors of ZF making one any time soon. BMW would not use any other tranny supplier. Period. There is a possibility of a highly strengthened Getrag with BMW's SMG system - to function like an autobox. Also - traction is an issue. I think the M7 will be a mix of 760 and M5. Not a bad mix. If new develooment occurs at ZF and Steyr-Puch (major driveline subcontractors to BMW) - this could be a sign.

yup yup

[thepolarfoxqx]

Should AWD be used in the M7? how about M5?

[850 Ci]

i dont think awd is needed

[thepolarfoxqx]

While I am a purist, and love the feel of RWD, an AWD car is much easier to drive hard under conditions.

Keep in mind, the current M5 will loose traction of its tires if you start a heavy accleration from stop with a clutch drop of above 1,500rpms.

[850 Ci]

For teh v10 im sure it will change

[thepolarfoxqx]

BMW is going to need some sort of amazing traction control/esp system to keep that much power screwed down (and huge tires)

Hallo thepolarfoxqx,

 

schau doch mal hier zum Thema Zubehör für BMW M (Anzeige)? Eventuell gibt es dort etwas Passendes.

Phew exiting times for BMW eh?

[thepolarfoxqx]

Amen to that.

[loxionchild]

polarfox man i think ur words r inspiring and that maybe r should work for a car mag or a show rather so u can get to drive all them super cars. I just have one problem though, as a bimmer fan i think u is immature in ur outbursts of expresive appreciation (like u talk too much) and there is no such thing as a M5 4.6is (u meant X5 4.6is surely).

much love to all other guys though, i'm new and i feel at home

cheers!!!!!

[thepolarfoxqx]

thanks, yes i have been known to talk too much, and I often mix up M5 and X5 (two very different things). I apologize.

I love the work BMW does (i can't wait till I can own one again). No one builds a car like BMW does. I have done some talking to people - and it looks doubtful that an M7 will ever come out, but there is word of a 760is. The 760 is to debut only in the long 760Li, but a 760is would be the short platform, maybe a little extra tuning in the motor, but similar to what the sport package is to the 540i, a shorter axle, etc.

Too bad.

Oh well, the new M5 is plenty good for me.

[loxionchild]

yah man... its all good, i'm also a huge fan (still growing) and all that stuff i said i was outta line!!! cheers

[M@rtin]

The BMW-dealer of my parents told me that BMW won´t build a M7. The 760Li is enough.

[thepolarfoxqx]

i am starting to hear the same, i am reading quite a bit about a sport model of 760 though.

[loxionchild]

is the 760 the one with the eco friendly engine?

[thepolarfoxqx]

Well, you could call it an eco freindly version. It's V12 can propel its over 4,500lbs of weight with better fuel economy than some v6 compact sedans. It has amazing technology that allows this, I can only hope they tune this technology for performance over economy sometime soon.

[850 Ci]

I am sure the 760Li is VERY sufficient! It has 450hp which is more than enough for a big sedan. but a 760Lis with like 500 or close hp would be close just to have some M involvment in the 7 seires

[thepolarfoxqx]

Well there is going to be no RS8 (you know that twin turbo W12 monstrosity)

The S55 will be packing 500hp from a supercharged 5.4L 24V V8.

S600 will be packing 460hp from a twin turbo 5.5L 36V V12.

760Li is packing 404-420hp from a 48V V12.

What is needed here is a 485hp (that is all that is needed to make a 7 series faster than a heavier S-Class.

[850 Ci]

thats very tue im thinking the same with 500 horses. but eh only problem is that the 5 series M would have top be more than 525 horsepower to make it look better

[thepolarfoxqx]

Well, BMW says no go (as of now) on the M7. To be an M Car, a manual transmission is a must. While bimmer's SMG would be fitting of a large sedan, apparently, something that big is more luxury than sporty. That said, a sports version of the V12 car is likely. Just enough power to make it faster than S55, S8, or XJR (which, for 2004 Packs a 390hp supercharged 4.2L 32V V8 to 3,600lbs - 9.2Lbs/hp.), S-Class is now offering 2 493hp engines, the first is a 5.4L Supercharged 24V V8 pumping 516 ft./lbs. torque, the other is a 5.4L Twin Turbocharged 36V V12 turning out 590ft./lbs. torque. Even though the S600 (that is the V12) is heavier, both should run about even acceleration times. For the 4,450lb. Weight, that equates to 9.0hp/l. The A8 W12 has 404hp from a Naturally aspirated 6.0L 48V W12 (sorry, VW/Audi confirms no RS8) to it 3850lbs of curb weight. 9.5hp/l. Now to beat all of these, bimmer needs a hp./l ratio in the eights (theoretically). The big bimmer weighs in at a severe 4,400lbs, though it sports a 6spd. automatic, for 04 jaguar gets one, word is that Audi and MB will be running 5spds. for a few years yet. Just the same, 495hp is neccesary for the big bimmer to edge out the two big Mercedes' - which is no stretch for the powerful and flexible engine. BMW could just as easily tune the 6.75L V12 made for Rolls Royce Phantom to run similar to the stock 6.0L V12 (the rolls version gives up signifigant higher end power to gain a very authoratative low end). Just the same, BMW needs 500hp from its V12 to compete.

[850 Ci]

It sure does need to have 500 horsepower to gain any advantage over the others.

[thepolarfoxqx]

it is also at a weight disadvantage to all of its competitors (it is even with S Class) - which is harmful to handling, next generation Jaguar XJ and Audi A8 cars will have 800-900 pounds of weight advantage. BMW is going to need to make 7 pretty special to compete, 745 is very luxurious and smooth, i assume 760 will be even more so, but people buy mercedes or lexus for smooth and luxurious, what is needed is a true BMW style performer (like the old 740i Sport).
