Mine gets 18-19mpg around town, with a lead foot, and about 24-25mpg highway. The 6 Speed 1995 540i with a Dinan chip is exactly as fast as the 500E, and would have no problem keeping up with an E34 M5. 5.5secs 0-60 for the 6spd. I've driven both....the 6-Speed is scary fast.

Well bring it out here son! Our next track day is a week from today Sat, April 03, 2010 in Fontana. We'll line 'em up!

I'll make you a deal: if you'll come out to our next track day, I'll
give you that ECU for your M103!
This is my knappy 400E holeshotting a 97 540i 6spd:
http://forums.turbobricks.com/showthread.php?t=193034&page=7 (Go down to post number 169, first and fourth pictures). In all fairness though he wasn't on top of his game yet cause it was in fact the track's first run of the day and the track was still cool and damp. (but he got much better later in the day, see next paragraph). He only ran a 17.73 on that first run. Still makes a nice picture though don't y'all think?
That 97 540i 6spd. got better as the day wore on. Here he is seen spanking a Camaro while running his best E/T of the day, a 14.908 at 97.33 MPH:

My best E/T of that day, a 14.530 @ 97.22 with this car's best ever 60 foot of 2.297 despite the track still being cool and damp, was ironically the run against him. That E/T is even with me hitting the rev limiter! (of course nobody got a video of our run but thanks to one of my Volvo buds it is at least caught on film). My last run of the day was a 14.727 @ 97.57.
For the record, this is kind of a "slow" track, over 1000 foot elevation, a so so launching area, and the last half runs slightly uphill! Don't forget those times you see published are corrected to sea level and cool temps (60 F I believe). The 14.476 in my sig corrects to a 14.07 @ 101 MPH!
Bottom line: Benzes rule







Bimmers drool!



Back on topic now I would add to Peter's post that spark plug wires are another very overlooked part under the hood. Look for arcing there too.
