The new 400 HP V8. That would be awesome.

it should do, I dont see why not.
But if they do put this engine in the 5er and 6er then less ppl will buy the M3 :P

I think you're confusing the NA 4.0 V8 in the E90/92 M3 with the TT 4.4 V8.

no I have not got it confusing
I know there is a 4.4 V8
what I mean is you get about the same hp with less money and more mpg
there is going to be a 560i too
here is the engines for the F10

Start-stop automatic transmission will be used for the six cylinder engine, in order to increase fuel efficiency. There will be a wide range of engine offerings, from the European 204hp 2.0L twin-turbo four-cylinder diesel engine to more powerful ones like the twin-turbo V8 4.4 liter engine.

The petrol engines? power range from about 180 to about 407 horsepower and the diesels from 180 to approximately 290 hp.

407 hp :o more than the e39 M5 ! >.<

Yeah, well weight is another factor...

I think outside the US a NA V8 will be available. In the US it will be TT V8 & TT I6 ... other than the M's which are supposed to go TT too later.

A TT M5? I mean, correct me if I'm wrong but wouldn't the modding possibilities be as high as the 535? Throw a chip in here, remap an ECU there and you've got an M5 mauling Italian exotics. Or is it more complex than that? At least increasing the boost a bit should have the M5 tearing it up, not to mention losing a couple pounds from moving from a V10 to an 8.

Since when are //M engines only about horse power ... what about power-to-weight ratio of the entire package, lightweight F1 engines, individual throttle bodies for flawless response, DCTs/MTs, high-revving acceleration all the way to redline .. , built on prob. the most well balanced chassis on this side of 120K! It used to take some understanding, "passion" and practice to drive the //Ms to even close to their potential. The //Ms were kind of a relationship in which you "grew" to appreciate it and at the same time practical enough that the wifey (or better half) can still use it without you ending up on the couch for the night.

Now it's all about get in ... turn on the gas .. put the transmission in "D" and .. step on it. I am NOT saying it is BAD THING but it is NOT on which the //M brand was founded ... !

The X5 and X6 //Ms (which are really a "new" top of the line regular series models ... ) are an abomination of sorts and the //M engineers KNOW IT .. they did it to SAVE THIER JOBS and the division (thanks to a piss-poor economy) .. and I applaud them for coming up with a beauty of a power plant in such a short period of time. But make no mistake ... the X5/6M in NO CONCEIVABLE WAY is even REMOTELY built from a track platform (prob. <10 laps on a hot day in a race track and you'll need a tow truck to haul your a$$ out). They said it matched the 'Ring time with the E46 M3 .. but JEEZ .. that's with almost 200 hp and 200+ ft/lb of torque MORE.

And ... when ever did //M decide to build and tune something called an //M sport automatic with an //M sticker stuck on that norelco shaver!

Yet I still believe that all that quick money and huge profits that these cars (hopefully) generate will actually lead the //M to the drawing board to build true race-bred (high revving turbo charged) M3 version from the ground up that will compete with the best. If they ever do what they did to the X5/X6 to the next //M3 ... oh well .. we'll leave it at that.

Just check out what engines BMW has now to offer, that will answer all your Q's about the F10.

They have a 3.0 liter L6 and a 4.4 liter V8, with one or two turbos.

Power from 326 hp to 555 hp and a horse load of torque in any engine.
