How fast have you driven your M3?

[Juano11]

115mph, and it was honestly an accident. I had to pass some jackhole on the right, I wasn't happy about it, and gunned it perhaps a little too hard. When I looked down, I was doing 115...faster than I ever meant to go on a public road....

[carri0n m3]

145 mph on the bahn during the break-in period and agree w/ others that it was at or below the break-in rpm's; still felt like car had some room to go but did not want to push it...

[rea1000]

175 on florida turnpike. Still had more!!! But I chickened out

[wolftrouble]

Plaid.

[jbeene]

M3 = 145 mph (track)

335i Dinan S2 - indicated 167 mph and still pulling (secret proving ground....)

[duk]

165mph balls limited

[powertrip]

I touched an indicated 155 mph at Big Willow; she was still pulling surprisingly hard .

In theory, the M3 would be doing aprox. 193 mph in 6th gear @ 8400 rpm according to my calculations. It might be drag-limited before that point, but maybe with enough open road in front of you

On my car, the digital readout reads a little lower than the regular speedometer reading. I have noticed this when using the cruise control on the freeway. The needle on the speedometer might say 80, but the digital reading will say 78. Maybe all the cars aren't like this, but mine definitely is.

I think BMW put it there to give us a more accurate reading while still having the buffered main speedometer calibration that is likely required by law. I'm sure the digital reading is still on the high side, though.

Havent ordered my M3 yet to test this, but if my 07 328i Sedan Hit 145 and I had it in 5th gear, Im very curious what the m3 will do.

[MrHarris]

I hit 165. It pulls pretty strong even after 150. I'm guessing it'll start to slow around 175.

[JC919]

to ludicrous speed

[BMWDEMON]

155ish...kept my eyes focused on the road while the fiancee told me what it was...still pulling! I need to see what it can do after the AA work but there is never enough time/room on the highway...I need to wait until I got to PA again which is in a few weeks.

Several times to the stock electronic speed limit (270km/h odo / 250km/h true speed). Anything above 230km/h and you need to be focused, but below that it is like cruising down the road. Even at higher speeds the M3 feels pretty solid.

[jbeene]

There is a youtube video out there that shows an M3 digital readout climbing all the way to 327 km/h. Which I think is about 205 miles an hour.

Not sure how this even possible but I'll see if I can track down the video tonight and put in a link. Must be pretty heavily modded.

The M3 comes limited at 169mph. I experienced it three days ago on the Autobahn. The needle reached 170mph and then it cut off. Taken into consideration the speedometer error my 170 might have been a 165 or 166mph. The car feels solid at that speed.

If you don't have an ECU upgrade delimited there is no way your M3 will still pulling after 175mph.

I reckon serious mods would be needed to see 200mph. Maybe someone on here with the supercharger can confirm if they can reach it. A Z06 with better aero, 505bhp and less weight can't reach it so we have no hope.

I don't believe an M3 or any of it's competitors will see 190mph in reality (as opposed to rev limited theory).

If I remember correctly the result of the calculation, the theoretical max speed achieved by the stock 420hp (at the crank) is in the region of 300-310km/h (assuming that the speed limiter is lifted).

[This is based on a certain combo of assumptions about air density and engine / transmission / drivetrain & tyre losses].

[FStop7]

Road and Track had to pull the mirrors off and tape up the front of a Murcielago and still didn't get quite 200mph out of it. An M3 isn't getting there.

You must have gone a lot faster than 65 MPH . . . you were pushing your engine so hard it turned ORANGE!!!!

Not really sure just how fast; maybe we should ask the STI driver I just smoked on the freeway today...
