Oh...don't forget about your air filter. That's just as important as your oil!!!

Just for fun I did one run accelerating only to 4500rpm and got 6.96(still impressive) Either BMW's steptronic has been perfected to the point where its just as efficient as a manual(if not better) or BMW really understates both their 0-60 times and their HP numbers. Anyway, i love this car, glad I went with the 330 there is def a noticeable difference in power. When my sister had a 325 loaner and I did the same thing, I could never break 7.1.

5 locations in one day isn't enough,you might have similar barometric pressure throughout the day.
throughout a cold winter very low humidity day,you'd have much better numbers than on a hot humid day or a cold humid day.
You need to run both cars under the same conditions.
I have a 330i auto as well,to my chagrin,her manual sister has an edge though.
Engine HP will also vary based on environmental conditions.
Did both car use the same gas? A loaner car is more likely to have lower octane fuel in its tank.
Here's the disclaimer from BMW.

BMW AG test results.Actual acceleration results may vary,depending on specification of vehicle;
road and ENVIRONMENTAL CONDITIONS;testing procedures and driving style.
These numbers should be used for comparison only and verification should not be attempted on public roads...

If the septronic was perfected to the point where it's just as efficient as a manual(if not better).There wouldn't be a need for the expensive SMG,would it?

To the OP, BMW specifically gives the Steptronic a very aggressive first gear so that it doesn't fall as far behind in acceleration as it would have normally.

I'm also interested in how you're timing this stuff, stopwatch? Are you doing it or is someone else in the car? Shouldn't your eyes be on the road?

Well, I have almost 800 miles on the car now and there seems to be no problems at all. If anything, everything has gotten much smoother. Like akhbaat said, the engines are redlined at the factory. Going from experience, taking them to redline is not a big deal at all. I even waited till 300 miles.
The runs were timed with my own stopwatch. When my friend was in the car and did the timings they went up by a little. (6.3-6.4) I-drive stop watch sucks for timing runs b/c it has a 1 sec lag + doesnt show tenths of a second.

I've done it many different times since then and I still consistently get those numbers. If the manual transmission has that much of an edge then i have no doubt about the magazine tests being able to get sub-6 sec. to 60 with a manual. Btw also to get those numbers, I power brake till about 2800 rpm and the release in d/s mode. I also have the A/c turned off.

I dont know what octane they use in their loaners but I use 93 octane all the time. I'm sure that does not make that much of a difference. Possibly, .1 seconds. Also the loaner had 1200 miles, prob rarely driven hard.

I redlined my baby the night I got it, and have been continuing the abuse on a consistent basis and she's been running true and strong, now at 5500 miles.

That's my philosophy ^ Just enjoy your car cause that's what it was made for. It's a performance sedan. Anyone who wants to baby it can it baby it but theres nothing wrong with pushing it either. THat's why we have a redline to begin with.

[Ethirtynine]

What instruments did you use? Please don't tell me you used a stopwatch

[Wolf359]

I wouldn't take any advice from somebody suggesting to put anything else than synthetic oil in a BMW engine, that is ludicrous.

[Hawkeye3]

With respect to ignoring the break in period, my only question is why? It is that important to redline the car off the lot? Even if there is a 2% chance it would damage my engine or decrease performance I can wait. I plan to own my car for a while and waiting a bit to really push it is not a real sacrifice.

[Dukenole]

Let's use some common sense here. Dyno testing it to redline for a brief period versus driving the car to redline on numerous occasions are two different things. That's like saying because you ran a red light once and didn't get in an accident you can continually run red lights and not get in accidents.

Your trans and brakes are hardly broken it, let alone your engine.
You're timing 0-60 runs with only 300 miles on it.
Dumbass.
I hope you're leasing.

Dude, you own a BMW in Chicago???

Dumbass.

I hope you have GAP insurance.

I'm not sure but from what i watched in that E46 manufacturing process did you notice that they gassed it up, fired it up and moved it to the dyno. Does anyone know if they at least lubricated the engine etc at start up? Hell they didnt seem to let it warm up and they rolled it onto the dyno and ripped it up to redline. I think there's a lot more wear and seating of this and that just from the initial start up.

Also, when you're BMW Center PDI's your car...and they take it for a spin to make sure all is well...do you really think that Tech that gets paid somewhere around $80-100 per PDI really gives a rats ass about not going passed 4500 rpm? NO I have friends that are master techs and they beat on the car like a left handed red headed step child.

back on topic though, you need some better instrumentation to do your timing with and yes zee germans do have a tendency to underate their performance

it does but as I recall it also does not do tenths of a second only second as a whole......something to ponder

Hey agent0986,
Where you at in Long Island? We should do a small Long Island E90 meet this month.

[uhaulball]

yes we should

How about this weekend? Somewhere with a open road.

hey, im in northern nassau, right near jericho...i actually live 5 min
from uhaulball....yeah we should def do a mini one...me and uhaulball
still have to get together and race (330xi vs 330i)...maybe this weeekend?

[uhaulball]

im changing my avatar info to Long Island, NY too... gotta rep the LI

[Hawkshaw]

What? A discussion about the break-in period on e90post? Now that's a first!

Personally, I am respecting my break-in period, but it's nice to know that when I'm able to let 'er loose, that there may actually be slightly better performance than advertised. Now, if only someone would conduct the same tests with a manual...hmmm...I feel an e90post.com search coming on!

Cool. I am on the north shore long island as well. please PM me and I'll give you guys my cell phone number lets make this happen. I'll tell a friend of mine to bring his 2003 CLK500 too.

1) Its for less than 2 minutes, and just to test the engine

2) I can tell you a local BMW Tuner I know very well has for years asked people questions about their cars before Dyno test and before engine stripping. Questions were about running in period, oil change period and oil usage by the engine.

For the E46 his 6 year results have conclusively shown that engines that are run-in by their owners on average have more power and use less oil than the ones pushed since day 1.

He says he hasnt seen any noticible differences on tolorances on engine that were stripped for upgrades between cars following bmw's oil service interval and those changing oil earlier.



Its still to early for E90 results
