The bimmer X6 will it seems be the first bimmer with that new 4.4 liter twin-turbo V-8 bimmer has been saying they will release, now they are by this summer. After that they will obviously put it in their 5 series, 6 series, 7 series, and X5 cars. The engine has 400 HP and 450 lb/ft of torque. Vishnu will definitely come out with a quick ECU software upgrade that will most likely put it up over 500 HP and 550 or closer to 600 lb/ft of torque for probably around $2,000. It looks like this new engine will take the place of the engine that goes into bimmers current cars like the 550i, 750Li, 650i, etc..

This is just more evidence that for sure Benz knows they have to quickly upgrade their 550 engine like all the rumors have said they would. 382 HP and 391 lb/ft of torque just won't do it now it seems. With direct injection and some ECU upgrades what do you guys think benz can get the power to? 430 HP? 440 HP? Torque will need to go up alot also.

This is also further evidence that bimmer knows that with a sofware upgrade their new twin-turbo V-8 will keep up with their M5/M6 for sure, so they have to install twin-turbo's on their V-10 for sure now. Audi has already done it, and AMG had better for sure have their twin-turbo 6.3 liter V-8 ready soon, too.

It only makes sense now that BMW will probably have an all-new direct injection twin-turbo V-12 (maybe 5.4 or 6.0 liters?) engine ready for their new upcoming 8 series, new Z9 (which will be the SL competitor), and most likely as a top of the line choice for the all-new 7 series coming out in a year or so. The ante keeps being upped, but that's good for us consumers though ...

Thanks for posting. I will want to see this in real life. Was thinking (for my wife instead of the RDX) about the new small ML (MLK?) coming out next year or the small Infiniti EX, which appears to be similar looking to the X6. Just dramatically under powered as is typical of Infiniti. This is now a stong contender. Not sure about the view from some angles though. I hope MB doesn't under power their new crossover.

 

This can't be right.

It looks like the little nissan suv. Only a 350 model as the biggest engine? I guess the X3, poor as it is wont have much to worry about if this picture is accurate. Any one seen a better picture?

 

I hope this rumor is false, it's just weak to see the twin turbo-ed 4.4 v8 makes 400hp, a what 40hp gain over the regular version of the 4.4?

It's not even close to 100hp/L for christ sake. For comparison the 3L in 335 makes 100hp/L, so I have to guess that new engine has to make at least 440-450hp, not 400hp to make it worth while to go into production.

MB's 5.5L V8 is a strong engine, it feels more powerful that the 380hp suggests, coupled with the 7-speed auto box it's one of the best engine-tranny combo out there, just like the old 55k + 5speed.

Somehow I don't think MB is sweating yet over this.

 

i was thinking the same thing. the power increase isnt worth the trouble. i'm sure you'll see more HP than that

 

Whoopsy- If they put the 5.5L and 7 speed in it, it will be great. I thought the 350 is a 260hp V6 which is really light for a 4000+ lb SUV if you want better that 7.5 sec 0-60. I hope they offer the 550 engine.

 

Well, 400 horsepower is 40 more than the 4.8 liter engine in the current bimmer 550i, 750Li, 650i, etc.. cars. The original 4.4 liter V-8 you are referring to from BMW from a few years back made 325 horsepower, so 75 more then.

Also, this 400 HP number they are putting out might very likely go up, and if they still state only 400 HP for a 4.4 liter twin-turbo V-8 then surely like many other German cars it is very very conservative and when placed on a dyno it will most likely put out quite a bit more than that.

Further, the tuning potential for a twin-turbo engine is just immense, and the value for every dollar spent is excellent. I hope Benz puts Twin-turbo's on much more of their engines soon.

Vishnu and Dinan will for sure have ECU upgrades available right away after the release of this engine that will put it above 500 HP and way over 550 lb/ft or maybe 600 lb/ft of torque. And for that matter some other tuners
will definitely have ECU upgrades ready quickly for the coming 2009 RS6 sedan twin-turbo V-10 that will put it well over 700 horsepower and ofcourse it has that crazy high-tech AWD system and carbon ceramic brakes. The ante keeps being upped substantially.

Audi already is going to give us a twin-turbo V-10 RS6 sedan soon, Bimmer is going to put forced induction on their V-10 in the M5/M6 to stay competitive, Porsche already has a twin-turbo V-8 and will be readying soon their all-new Panamera cls-type sedan and 928-type coupe with a very powerful twin-turbo V-8 and later on possibly a tt V-10 also. Bimmer it seems will logically next twin-turbo their V-12 for the all-new 7 series coming soon and for the all-new 8 series coming and the Z9 convertible which is supposed to be a competitor to the all-new SL coming in 2011.

Now is the time for benz to drop the hammer and go full force twin-turbo. They really need though to focus on a good LSD for these cars, dual-clutch trans, lighter weight, amazing brakes, and maybe better handling. All in due time!

Lets not forget that Benz is still developing their twin-turbo 6.3 V-8, and a twin-turbo 6.9 engine that could either be a V-8 or V-12. Their have even been rumors that they are working on a possible 7.3 or 7.4 liter twin-turbo all-new design V-12 for the next top line AMG car (why else would they reserve and trademark the name "6.9 AMG" and "7.4 or 7.3 AMG" for their future cars), like for a limited run of maybe top of the line SL's, CL's, and S classes. Maybe even for a run of next-generation black or signature series AMG cars.

 

Sounds VERY interesting!

 

from the BMW website its a twin turbo 4.0 liter v8 w/ 400hp and 450 lb/ft torque

 

the new twin turbo engine will be rated at 400/450 to stay away from the m5/6. in all reality, it will make well over 400 hp. look at the 335i & the new m3. 335=300 hp, m3=420 hp.....335 does 0-60 in 4.9 versus the 4.8 of the m3. the tt 3.0 engine is severely under rated as not to take away from the m3. same will be true of the new tt v8.

 

The new GLK is getting the 350 at the max as its base is the w204. there might be an AMG version down the line though!

 

It's not that BMW underrates the 335 engine by a lot, at most 20-30hp, but more like how pathetic the M3 engine is. 335 engine makes 300lb-ft of torque at 2k rpm, pretty much it will pull from idle to the end, but the M3 engine makes virtually no power until almost red line, so off the line it will lag way behind until the rpm is high enough to be in the power zone. 0-60 times are mostly about low-end torque and how the HP is produced, so unless the M3 uses high rpm clutch dump, which btw is really hard on the clutch and the Bimmer clutch is not cheap, the 335 more than likely will be ahead of the M3.

Also, I think I remember reading about the X6 in autoweek recently and it was saying the new TTv8 is rated at 450hp. If that's the case, I think the HP rating makes much more sense.

 

the current 5 liter in the m5 is a "concept" engine. small displacement, small stroke and bore.

they dont need forced plumbing to bump up the hp and tq significantly- all they need is another 0.5-0.7 liters displacement to push 600hp if needed be. dinan has shown that the 5-liter has great potential with their new larger-displacement kit.

dont mix the "m"-division philosophy with the one from mb and audi. m is all about compliance (read power to the ground) when pushing the envelope- something that is very hard to achieve with blown setup. porsche and bmw do know that and their sportiest offerings are and will be n/a.

Lot of unsubstantiated speculation here.

What I will say is I prefer the X5 to the X6. As regards the NA 5.5l V8 being the best match for the 7-speed, I'll say that the NA 6.2l AMG unit is superior in all areas.

Don't forget, a very small percentage of people modify their cars. This is an enthusiasts forum so it seems common but it's not. Stock-stock the V8 M3 murders the 335i in all departments.
