BMW 555i to Debut in 2009

[LeMansX5]

Last summer BMW began the process of trademarking for the name “555i”.
This began with a bunch of rumors earlier this year that a new 5.5l engine was in the works, we know that is just not in the plans for the 5 at this time. The N63 engine being released in the new X6 ‘50′ will be the engine of choice. The N63 is an aluminum 4.4L, twin-turbocharged, direct-injected V8 engine from BMW that will be released officially to dealersrs this May.

The N63 produces 400 hp and over 450 ft/lbs of torque according to BMW. It utilizes a newly developed concept in the location of the turbos. The turbochargers are mounted in the “V” of the engine and the intake manifolds are located on the sides of the block. This allows for a more compact engine and reduces the overall width of the assembled engine.
This engine features an air-to-water system for the inter-coolers. This is a great deal more efficient and provides a shorter air path to the engine (reducing weight) than using a standard air-to-air inter-cooler. Like its’ sibling the N54 inline six twin turbo this engine does not utilize the usual BMW Valvetronic systems found in naturally aspirated motors.
Expect to see this motor utilized in the 555 much the way the current V8 is. Overall it will be the sportier model in the line up and offer the standard options and features the current model has. The availability of the sport package with aerodynamic body kit option will remain with some slight changes, including limited edition color choices. Choices of transmissions have not been officially confirmed but we have received several hints that point to a milder DCT will be available when combined with the sport package.

With the 5 getting a little long in the tooth we expect to see some interesting marketing strategies in the form of packages, colors and limited edition items, this just being the first; stay tuned!
We also have indications that this engine will be utilized in all the current V8 models and in future models. BMW invested a lot of time and resources into the development of this engine and will be utilizing it across most model lines. Much as in the past certain models will be picked from the get go and the rest it will trickle down to.

It won't be long before we see the same engine lineup in the X5

[X5Dawg]

Hmmm, an X555...

[vinuneuro]

The 555i is going to be a BEAST.

I wish they'd stop calling it a newly developed concept though.

Finally a real torque number

Of course, it will probably be about $70K

[Kewl X5]

So when is the X5 xDrive 50i coming out?

...for a base model with no options...

What is new is the concept of the turbos in the valley pan (like your truck engine) in combination with the intake manifolds on the outside, and exhaust manifolds on the inside. Lots of engines have put turbos on top, but changing the heads and the flow direction is a new step AFAIK. Certainly the long exhaust pipes wrapping around the back of that corn harvester engine are a big step removed from the N63.

So what are the odds of the 2009 X5 4.8i going away and the replacement being the 2009 X-Drive 50i using this engine?

I see now.

Btw, I don't work for them anymore and good riddance. Must be one of the few companies that can take a perfectly good Class 8 MAN engine and somehow f*ck things up with it. Since I left they hired the head of engr at VW, so maybe things will be better at least on the engr side. Still a really poorly run and non-dynamic though.
