New BMW 4.4l V8 twin turbo engine

DINANM3 · #1 05-27-2006, 02:16 PM

Has anyone heard about the new 4.4 v8 twin turbo engine BMW is working on. It should be out in 2008. Just in time for them to come out with a new
X5 i.s. model replacement. Iam pretty sure it is going to be the repalcement for the current 4.8is. The engine will be putting out about 460hp and 460 lbs of torque. I can wait. I guess BMW is going turbo with all there motors. they really dont have a choice though, with the new emmissions laws, gas prices and hp wars. they have to go turbo. But the M cars will always be NA. I guess there is going to be some serious changes in BMW engines over the next 3 years. Cant wait to see what they come up with.

would be interesting to see what bmw comes up with. interesting to notice though benz went with a large displacement 6.3L V8 in the ML63...i am still not convinced turbocharging is the way BMW should go to fight this HP war...i've always been respectful of bmw producing these ingenious cars and engines without having to use force induction...as long as the M cars stay that way then I guess i dont have a problem with it...but times change, i guess change is good.

I thought BMW were looking at a V10 engine for the X5M (E70), does that sound right still regardless of the Twin Turbo news or do you think its instead of?

Allthough many say the V10 will be going into the X5. I really dont think so. And now that i found out about this new turbo 4.4 i really dont think it will happen. This V8 is going to have almost as much hp as the V10 but an extra hundred bounds of torque which will be available from around 1500 rpm with a very flat torque curve which is what a heavy truck needs. The V10 in my opinion is not well suited for a 5000lb truck with an automatic. And the V8 would be faster anyway at least to 80moh because of all that torque. The V10 is really a car engine.

good point, the v10 doesnt develop enough torque for a big sav like the x5!

i could understand supercharging it, but any of these new cars with turbos on them are going to get raped when it comes to warranty....nissan only makes SC'ed cars after the 300zx twin turbo (destroyed them on warranty problems) i think it would be better for a SC for the X5...turbo's come into play at higher RPMS...which really isnt what the X5 is driven for...SC would be a better investment..off the line AWD torque =c]

New Technology bro. Turbos have come a long way since the 300z. Turbos are now better than sc. no parastatic loss due to the pulley. The new turbo engines especially bmw and porsche have absolutely no turbo lag and torque is available pretty much off idle. and they have a huge flat torque curve. Your comparing todays designs with a car that was designed in the late 80s. And nissan is no where near the level of BMW when it comes to engine design.They dont have the money or the engineers to even come close

Make a research on audi's failures with their turbos.The are supposed to be same as porsche and VW.The fail a lot and they suck in the meantime

Really even the porsche turbos fail alot. Ive never owned a porsche but i thought they were pretty reliable. Although audi does suck.

I wasnt really talking about reliability though because i am sure especially with the first few years that they will not be as reliable as the non turbo motors.

My point about the new and old turbos was that now there is no turbo lag like there used to be and also there is torque available immediately there is no waiting for the turbo to spool up.

are you kidding me?

please elaborate what you mean by "new technology" bro, cause last time i checked, ball bearing turbos arent "new technology".
the turbo's i have in my car are nothing but 1 year old, i race my 300zx twin turbo at leguna seca and button willow, and thunderhill...i am right there with "new technology". dont tell me nissan doesnt even come close, cause nissan was the first car brought out to compete with the chevy corvette and beat it(read your sports car magazines). and most american's dont even know about the import supercar, the nissan skyline GTR34, which is still considered untouched in most aspects to super cars. and its 16 years old......

EDIT: (as are many other sports cars considered untouched in many aspects also)
