That would be me.
Just wait until July 30th. You will have data from 545s and 550s. We just need to find a place.
EBMCS03 hows the search going? Hollywood, Ice, bmw4life -- Guys, try finding us a place.![Thumbsup](https://5series.net/forums/images/smilies/imported/thumbsup.gif)

Unless you compare the cars side by side, numbers from other sources, taken at different altitudes and temps, are not comparable.
So go find a 550 and time it along with your car - or reference C&D because they actually adjust for temp and altitude (and have the 550 about .03 seconds faster if I remember correctly.

I've never tested (timed) my car with a stopwatch, but I've always suspected that its 0-60 time is closer to 5.3 than 5.7 (BMW spec).
2004 545i Step. And the acceleration from a rolling 20mph - 70mph is unbelievable.

I like it, but no 545i/550i SMG has been tested as far as I know. Realtyman got a 5.35 0 to 60 in his SMG 545i--measuring with his GT2.
First of all, I was one of the 1st SMG's on the east coast (just behind Rudy & JDN).
I am a true SMG fanatic and advocate.
That said, I will never claim (not that I can recall that I ever did) that the SMG is quicker than a Step or a traditional row-it-yourself manual.
Actually, I beleive that the SMG will most likely be consistently "slower" in a straigt line drag race.
Yes, the SMG will shift consistently quicker than a traditional manula, however the inability to modulate the clutch at launch will almost certainly leave the SMG behind.
OK... Accelleration Assist is there, I agree, but unless you are on a smooth surface with relatively relatively new tires you'll just sit & spin.
Now on a road course...

My car keeps up with the Manual 550i tested in MT 7/06 and is faster than the Step 550i tested by Auto Zeitiung. And, the manual 550i is faster than the Step 550i since my car is faster than the Step. Thus, the fastest 545i, the Step, is as fast as the fastest 550i, the manual. Thus, the fastest 545i is as fast as the fastest 550i, and we can say a little loosely that the 545i is as fast as the 550i. We might even say that the Step 545i is faster than any 550i since my best is 13.4@106.4, while the best know 550i pass is 13.5@105. ![Smile](https://5series.net/forums/images/smilies/imported/smile.gif)

Like someone posted that they might have put a test version of the 545 motor in your car, the way it was pulling away from the 545 it would appear that they might have put a test version of the M5 motor in mine

I suspect that Znod is right about his 545i being faster than the 550i tested. Afterall, he has lighter wheels, no spare tire, and probably weighs in a lot less than the other test driver. I'll have to side with Znod on this one. I think you won't see power different unless you start from a triple digit roll.

I timed my 545 auto using G-tech last month and in the firs 2 tries got 5.11-5.12 sec to 60 mph in 85 F weather. No break-torquing. This is very difficult to believe. Honestly I do not trust G-tech results at all. If I remember correctly the best 0-60 mph for a manual 545 was 5.4 sec. Manual 550 when tested by some magazine got to 60mph in 5.0 sec flat. So we can say that 550 is about 0.4 sec faster to 60mph and auto 550 should be capable of 4.8-4.9sec to 60 mph. It also very likely that both cars are traction not power limited.

BMW 545i--Manual CD 5/04..........5.5...14.1...102.8 (adjusted for weather; 5 MPH roll)
BMW 545i--Steptronic RT 6/05......5.2...13.7...104.0 (aggressive, but not abusive)
BMW 545i--Steptronic MT 8/04......5.4...13.7...102.1 (adjusted for weather; 1' rollout)
BMW 545i--Steptronic MT 11/05.....5.5...13.8...102.8 (adjusted for weather; 1' rollout)
Well calibrated meters will be highly accurate. You got some nice results. Way to go.
