Hotness...now it finally can compete with the Audi RS-4.
|
Damn thats sexy
|
Updated with more engine details. BER:thumbup:
|
Awesome! Why do the headers glow red-hot during testing? I don't imagine that happens when driving the car, does it?

I still wish BMW would put some real torque numbers down for these HP numbers. 420hp/420tq...that would be a motor :drool: |
:wow:

does this mean more torque than the m5/m6?
|
LeMans,
Thanks for compiling all the info and pics as always!!:thumbup: KirkX5M, the 400 NM torque converts to 295 lb/ft of torque. So the torque is similar to the 335i, but about 90 lb/ft shy of the M5/M6 V10 engine....Remember, the M3 engine has 2 cylinder and about 1 liter less than the M5 V10 engine. Quote:

my bad i read it too quick didnt see it was in NM . dang. hopefully that is not an issue!
|
Don't worry, if they keep the car light, it definitely should be faster than the RS4...Look at page 24 of the PDF file and you'll see the nice torque curve that only a naturally aspriated V8 could deliver vs. our S54 I-6!! :)
|
i was banking on weight saving materials that would make this thing fly!!!! ill look at the pft file on my lunch!
|
nice........is this a regular V8 or does it have a twin turbo? just reading so much about new cars/engines coming out...trying to keep my facts straight?

That hp curve looks like the side of a sky scaper. Wow thats alot of hp

Drop that engine in the E70 X5 and I'll be good to go :-)

100+hp over the old engine
33lbs LIGHTER than the old engine engine blocks made at landshut, bmw's f1 foundry OMG audi CHECKMATE (and honestly i think the c63 will be a bloated farce) and lets bow to the BMW gods!!!!!!!!!!!! |
hottttt!!! This'll sure be a rocket!

I wished the //M and V8 weren't so close to each other. Maybe the //M badge above the V8. Or just ditch the V8 badge.
I wanna hear how it sounds!!! |

Check out the DSG clutches, very very cool!

Sorry if I sound old fashioned, but I'll still take a 3-pedal. This time BMW didnt screw around with the 6MT and DSC like they did with the M5.
|
it does... pretty typical.

the problem is it doesn't make any significant torque until 6100 rpm. peaky engine once again.. It's not similar to the 335i.. the twin turbo motor makes ~300lbs of torque at a little under 2000rpm which is pretty much off idle so it will have really good power up top again but you gotta wring it to get any power on the street.. great for track but that's about it...

the 400NM @ 4000rpm is wrong Sunil. They wouldn't be quoting 400nm at 6100rpm then.

haha.. that's bogus.. what happened to hp = torque at 5252rpm?
remember, hp = torque * RPM / 5252 and 5252 is the constant. Quote:
|
Quote:
HP does equal torque at 5252, but only if both are in British/US units. Torque is listed in Nm here. All that aside, that is an amazing torque curve, and suggests that this engine is going to be very responsive in the mid-range as well. Not as good on torque as the 335 under 2000 rpm, but impressive for an NA engine. |
good catch jeff.. but why would BMW mention they reach peak torque at 6100rpm when at 4000 they are making the same?

First post in this thread lists peak torque at 3900 rpm. Maybe it's a moving target? (sort of like figuring out which car Josh will be driving next week?)
No F1 bashing allowed. We want to see if Ferrari can get two cars on the podium and catch up to McLaren in the constructor's championship.... |
Quote:
Ferrari will get there only if Massa doesn't have any cars in front of him :nanana: McLaren all the way! |
Shitty cuz it's true??? If you truly advertise a flat torque curve, it better be flat. time to go back skool grassshopper!
Quote:
|
dude.. how much variance can it be.. the graph is in a grid of 10.. oh wait.. now you're switching camps cuz honduh sucks??? dude.. :confused: :nanana:

plus..you were the one raving about the e60 M5 for a few months, and subsequently slamming anything ///M after getting rid of it :nanana: |
Josh, please just give it a break!:rolleyes: We understand that everyone has a point of view. In person, you are definitely a much different person than on the 'net.;)
|
just calling like it is. BMW rushs too many things to the market and this will be yet another motor that they did.
