My Ride: 535i
2007 530i:
max hp - 254 @ 6000 rpm
max tq - 221 @ 4000 rpm
that means:
@4000 rpms, tq is 221, hp is 168 (221 x 4000 / 5252)
@6000 rpms, hp is 254, tq is 222 (254 x 5252 / 6000)
2008 535i:
max hp - 302 @ 5800 rpm
max tq - 295 @ 4000 rpm
@4000 rpms, tq is 295, hp is 224 (295 x 4000 / 5252)
@6000 rpms, hp is 302, tq is 273 (302 x 5252 / 5800)
max hp - 254 @ 6000 rpm
max tq - 221 @ 4000 rpm
that means:
@4000 rpms, tq is 221, hp is 168 (221 x 4000 / 5252)
@6000 rpms, hp is 254, tq is 222 (254 x 5252 / 6000)
2008 535i:
max hp - 302 @ 5800 rpm
max tq - 295 @ 4000 rpm
@4000 rpms, tq is 295, hp is 224 (295 x 4000 / 5252)
@6000 rpms, hp is 302, tq is 273 (302 x 5252 / 5800)
Where did you get the numbers above in bold?
Everywhere I've checked has said this:
2007 530i:
max hp - 255 @ 6600 RPM
max tq - 220 @ 2750 RPM
2008 535i:
max hp - 300 @ 5800 RPM
max tq - 300 @ 2750 RPM
A popular phrase; "Horsepower is what you read about in magazines, torque is what you feel when you drive the car.
Somehow in your test drive you couldn't feel the additional 80 lb-ft at 2750rpm?
A couple of interesting quotes I found:
This Is a BMW, So Let's Start With Power
What does BMW's new twin-turbo 3.0-liter inline-6 engine do for the 5 Series? This 2008 BMW 535i test car with an automatic transmission effectively equaled the acceleration of a 2006 BMW 550i equipped with a manual transmission. The 535i's 5.5-second acceleration to 60 mph proves a sedan doesn't need the 550i's V8 engine to be quick.
Each new application of BMW's wundermotor leaves us breathless. The ease with which it makes belly-flattening torque translates directly to an ability to deliver an effortless experience when it comes to merging on the highway or passing, not to mention undemanding cruising at super-legal speeds right up to 150 mph, where the electronic limiter calls a halt to the fun.
---------------------------------------------------------------------------------------
The midsize 535i is not just an upgraded version of the trendy executive assistant's compact 335i. No, this is the executive express that the boss drives. Although its price is just out of reach for many, the executive can afford a 5 Series, and its price sets him apart as does its performance. This guy is smart enough to know that the 7 Series doesn't do well in a cost-benefit analysis... He could afford the $10,000 premium for the 360-hp V8-powered 550i, but it's no faster than the 535i, and yet thirstier. Yes, the 528i is $5,000 less expensive, but one freeway on-ramp shows its 230-hp engine is just adequate motivation.
Yes, the right BMW sedan to possess and enjoy surely is the 535i. Swift, comfortable and frugal, the 535i is the perfect balance between the performance we've come to expect from BMW and a new appreciation for practical science.
Think of the 2008 BMW 535i as a 550i with a big price discount, and take pleasure in one of the world's few nearly perfect sedans.
---------------------------------------------------------------------------------------
Bottom Line
With the addition of the twin-turbo six to the 5 Series, this stately car no longer requires a V8 or manual transmission to be entertaining.
---------------------------------------------------------------------------------------
Last night I had a date with some sexy twins, the turbos in the 2008 BMW 535i. There's simply nothing like stomping the loud pedal, hearing those turbos spool up and getting punched back in the seat by raw, unadulterated power, which in the 5 continues well into triple-digit speeds. While this kind of acceleration dictates keeping your eyes glued to the road, occasionally I'd peek down just to see the tach needle swing up to redline.
I've driven the rocket-fast 500-horsepower M5 and it is undeniably sweet. But the 535i offers all the power you need, for about $30K less.

That quote up there sounds like something a salesperson would come up with, fact is, if the 535 was so equal to the 550, the 550 wouldn't exist. So you must be getting something additional for your money. You guys are all quoting hp and 0-60 times, there's much more to the differences than power. The 550 comes with many more standard options also. You guys can keep arguing all day, quoting numbers and such, but the facet is all these cars have different trim lines and price points for a reason. Because you're getting more for your money, not just HP.

I wouldn't call this arguing, just regular old bench racing/ debating you will find on any car/ moto board.
The 5-series I'm most excited about, sans the new M5, is the 2011 twin-turbo 550i. That thing will be a beast w/ a tuner.

Sounds about right. If they would have done a rolling start the 545i would have done even better.

If money is not a factor (i.e. purchase price, gas mileage, etc.) I'll take the M5 please.
