I am a BMW enthusiast without much technical knowledge. I presently drive a 1997 BMW 540i with an automatic transmission (prefer automatic for work). I plan to purchase a new 5 series when then 2008 models come out.
Thus, I have three questions:
1. What is the difference (performance, 0-60 acceleration, torque, gas mileage) between the present 550i engine and the new engine due in 2009 as an F10 2010 model?
2. What do you think will be the difference (performance, 0-60 acceleration, torque, gas mileage) between the 2008 535i and the 2008 550i?
3. I drive with a heavy foot, as does my wife. My wife's Volvo XC-90 SUV (where we bought the 5 cylinder model instead of the V-8 in order to get better gas mileage and be ecologically friendly) gets only about 12-13 mpg for the 5 cylinder model due to our lead feet (as opposed to 18-24 as advertised). My mechanic has told me that this is due to the way we drive - quick acceleration making the engine less efficient. The V-8 gets about 18-20 mpg. Given all this information (I know, TMI), will the gas mileage difference between the 535i and 550I be that significant? Will the 535i get WORSE gas mileage than the 550I for those of us who like to accelerate quickly?
Thanks for any input you or anyone else can give me.

You can be rest assured the performance of the F01 550i over the E60 550i will be quite noticeable.
1. F10 550i acceleration times, I can't say but the performance will be much better than the current 550i. Note that the F10 550i will offer better performance than the S6 and E550.
The HP and Torque may be limited to about 420. The engine is capable of 500 HP and Torque. An indication of the potential of the N64B44O1 engine is the Alpina B7 engine which is a supercharge 4.4 litre V8 of the 545i/645i/745i.
2. With respect to the 535i, expect the same gas mileage as the 335i, maybe 1mpg less. I expect the real world 0-60 times to be close to the 335i, although the official time would say otherwise so expect the 535i to be pretty close to the 550i but not faster than the 550i.
3. The 535i will give you better mileage than the 550i. Expect 18-29 mpg range. I know of friends that are getting above 30 mpg on the highway with their 335i and 24.5mpg combined driving.
The F10 N64B44O1 engine (4.4 litre biturbo V8) will also offer better fuel economy than the N62B48 engine.

Regarding information on the upcoming 2008 5 series, does anyone have insights into whether BMW plans to use run flat tires for the 5 series? And if so, to what degree?
The model I am interested in is the 535Xi.
The BMW press release goes out of its way to say the tires on the 550i sport package's 19" wheels are non run-flat, yet BMW has gone to RFTs on both the 3 series and the X5.

If you are interesting in the 535xi, you know you can get it without the RFT.
Do you plan on getting the Sports package as well? If you don't want the Sports package then you have nothing to worry about.
As an owner with RFT, I found out that by keeping the tire pressure at the rated pressure addresses most of the rap the RFTs are getting. And there are 3 occasions where I can say "it was well worth it".

I have RFTs on my 2006 330Xi. I like the safety and convenience aspects, but not the ride harshness. Firm is fine, harsh is not.
Unless the 5 series suspension can do things to avoid the hard hits I occasionally get in my 330Xi, I want GFTs.
I thought the 535Xi would be like the 330Xi in that the sports package is cosmetic only, no change in suspension or wheel / tire size.

May I ask what your tire pressures are?
I check mine every 1000 miles, and maintain the 35 psi/38psi F/B and that took some of the harshness out.
The SP in the 535xi will have the same suspension as the 535i without a sports suspension.

I follow the recommended pressure on the decal in my door frame- 32 psi front and 36 psi rear, cold.
There is a lot of discussion on this in the 3 series forum. The original Bridgestone EL42 all season tires were especially bad. I replaced them with the all season Continental RFTs and they are much better, but I still get the occasional hard hit. By contrast, our 2006 X3 has EL42 GFTs, 50 series 18" tires, and the X3 does not suffer the same hard hits as the 330Xi.

I have a 2002 530i with 135k miles and want to order a 2008 535, any idea when I could order (I live in South Eastern PA)

Given the above, it seems there are fewer reasons to lean in favor of the current or 2008 550 as opposed to the 2008 535i. Am I missing something?

I understand what you mean. You just find the hard hit annoying.
With regards to getting the Non RFT with your 535xi, talk to your dealer and see if your concerns can be accommodated.
