Post New 760Li BMW gets 544 HP TT V-12 w/8-Speed trans!

Ok, so I guess this is BMW's answer to the S600.. it gets a 544 HP and 553 lb/ft of torque twin-turbo Direct-Injection all-aluminum 48-Valve DOHC 6.0 liter V-12..... wonder what the tuners like Dinan/Vishnu will be doing with this....

Also something to ponder... what will BMW's M-Division be able to do with this engine when they do get their hands on it? Since they got easily 155 HP jump over the 750Li's 4.4 liter twin-turbo V-8 for the new X5/X6 M car (It went from 400 HP to 555 HP)... then with an even larger 6.0 liter twin-turbo V-12 with 544 HP they should be able to get a 200 HP jump for the M version of this all-new V-12 engine... so well over 700 HP shouldn't be a problem to put in the upcoming Z9 convertible... very interesting.... 8-Speed M-transmission with 700+ HP 6.0 liter all-aluminum twin-turbo V-12 Direct Injection engine, 4-wheel steering, etc.. in a lightweight Z9 car with M levels of handling/braking, ... could be a good car...

http://www.egmcartech.com/2009/04/09...12/#more-32936

Another interesting question: If BMW offers an M-version of this twin-turbo V-12 for the all-new upcoming 6 series coupe/convertible (which should be a 2011 model right?) in maybe 2012 or so, would any of you consider a 700+ HP factory M 6 series with an 8-Speed DSG trans? It would give the upcoming AMG SLS coupe gullwing and the Black Series cars a run for their money...

Wouldent a performance car with 600hp tear a 8 speed transmission to shreds? I thought that was the main reason that the 5 speed is still in the AMG 55 series.

DSG type transmissions have proven to have a high torque tolerance (922lb/ft for Bugatti). But I think the 8-speed on the 7er is a straight automatic ZF.

Somehow I can't see BMW bringing out a V12 M. They are even quickly backing out of the 8 cylinder in the M3. If they did bring out a V12, it would be great news, but I don't know how that would fit with their Efficient Dynamics. I would be in the market for their Z9/M9 if they do that.

It doesn't matter what BM do to the 7 series, it still remains an ugly heap of
crap, and no comparison to the S600!!

It took BMW some time. The S600 sports 500hp since 2003 (yeah, that's 6 years ago). The S65 sports 612hp since 2005. Welcome BMW...

couldn't have said it any better!

the 7-series looks like a s s and i wouldn't be caught dead driving one even if it had 1000000 hp and 10000000 ft-lb torque

Can you amplify that remark, it's a bit scetchy.

"AMG planning hybrid, diesel models
10/10/2008, 5:15 PM
By Drew Johnson
It may be hard to imagine an environmentally-friendly vehicle sporting Mercedes-Benz’ AMG badge, but that reality doesn’t look like it’s in the too distant future. In fact, a top AMG exec has revealed that the brand will unveil its first hybrid model by the end of the decade.

In an interview with Car Magazine, AMG boss Volker Mornhinweg revealed that the performance division was working on a hybrid model, which should be unveiled by the end of 2010.

“Although hybrids normally mean more weight, we’ll use our knowledge of lightweight material to offset this increase,” he told Car. “And don’t forget, AMG is all about torque, and electric engines develop their torque at standstill.”

The upcoming hybrid model is expected to improve fuel economy by about 30 percent — compared to the company’s current 6.2L V8 — and will draw heavily from the technologies used in the recently unveiled S400 BlueHYBRID.

Diesel technology will also be a part of AMG’s future plans, although to a lesser extent than other green technologies. Mornhinweg indicated only a single AMG model will receive the diesel treatment, with the most likely candidate a small four-door sedan. Since the C-Class is Mercedes’ smallest sedan offering, we fully expect the C-Class to get the diesel AMG treatment in the coming years.

Mornhinweg also told Car that the days of extreme horsepower – such as in the 670 hp SL65 Black Series – are behind the German tuner. Instead, AMG will look to lighten its vehicles and cap output at a still rather stout 500 horsepower.

So while AMG faithful might have been concerned about the prospect of the brand going green, the conversion sounds light a win-win for everyone: The environment gets a bit of a break while drivers will still get the same legendary AMG performance, all while saving at the pump."

Sorry I don't see it, unless you mean the bit about capping horse power to
500bhp in a lighter car. Thanks for the read though.

That's the gist of it,no more increasing the power in subsequent models ,instead concentrating on lowering the weight and improving the handling.

Question Questions

Couple of questions for you guys, because maybe some of you know or have heard?

1) Dinan/Vishnu, etc.. I've heard have gotten the 3.0 liter BMW twin-turbo 6 cylinder engine in the 335i to 420 or even 440 HP with just ECU and exhaust/intake... so then: what do you guys think the gains will be with just an ECU/Intake/Exhaust upgrade to the 6.0 liter twin-turbo V-12 in this new 760Li? If you can get 140 HP upgrade from a 3.0 liter engine, then since the 6.0 liter V-12 is double the size does that mean you can get 280 HP out of it? So does that mean 800+ HP is possible? (544 HP plus 280)

2) Does BMW's new 8-Speed transmission help improve shift times or is it just for improved gas mileage? And can it handle such power if the V-12 is tuned for more HP?

Anything is possible but at the cost of reliability.
I highly doubt any reputable tuner would boost that engine by more then 80-100hp,to protect the transmission and other internals.
Similarly,V12 in S65 is boosted by Renntech and Kleeman by no more then 80hp or less.

I heard Audi is planning to change the W12 6.0 into a V12 TDI in the new A8. It will have over 500hp and over 1000NM tourqe!

Wonder how will that compare to AMG and 760i....
