E46 M3 SMG 0-60 Times
Discussion
Hi all,
I recently purchased a M3 and today I tried out a couple of 0-60 runs. The best time I got was 6.2. This can't be right surly? This was in S5. I tried S6 but too much wheel spinning to get a quick move off from standstill. Does anyone have any suggestions and has anyone tried this them selfs? I want to at least achieve the 0-60 of 5.4 as per manufactures guidelines.
Please help!!!!

The brutality involved in achieving published 0-60 times is so horrifically high that I cannot imagine ever wanting to try this in a car I own and pay to mend. If you want to compare performance times to be sure your car is on the money then I'd suggest you try some in-gear stuff instead. It has less driver variable, is way easier to replicate and won't leave your clutch/gearbox/diff in an oily pile on the road behind you.

A couple of points
BMW will have got the 0 - 60 time in one of two ways:
1 - a computer simulation (this is how they calculate mpg figures)
2 - absolutely perfect conditions with the car running as light as possible ie just enough fluid in the car to do the run, a prof driver etc etc
Secondly, you car is already used (and possibly abused) and therefore the chances of it being 100% as it was as it left the production line is about nil.
How are you timing yourself?
Like others have said, really going for this is abusive to the transmission in the extreme and in gear, rolling times are the way to go.

1.) Your speedo will have an element of error in it's reading - they all do.
2.) Your (or your mates) reactions for pressing the buttons on the stop watch will increase the error of the reading to a level that effectively makes your performance measurements completely worthless.
3.) As mentioned above, launching any car from a standstill puts a lot of stress on the transmission and drive components - even more with a powerful car with big boots ..... Assuming that it is your private car, you are the one that will be picking up the (potentially very scary) bills when something twangs.

Autocar use draytron timing gear - this costs mny £k's and is GPS derived. They do many many runs - a car being treated like they do to get thos times really isnt great for it. Remember for manuals they willdo full throttle gear changes i.e. bouncing on the limiter from clutch depression through nex gear engagement and clutch release. They will try countless launches to get the best launch rpm and best slip (wheel slip).2.)

I think Autocar did a test a long time ago - where by they ghad Sutters the pro test driver then a professional race driver then one of the autocar jurno's (so still a pisonhead) and then Joe Public non pistonheads.
They had countless runs all day long and did get better but they were still well over a second off what Sutters could do - and the race driver even though he was closest was still a long way off.
At the end of the day noone drive's their own pride & joy like that the damage/wear out of parts will be significant & you could get a really pricy epai job + tyres are not cheap in an M3...
As others have pointed out your car isnt new its x years old with x miles on it so it will certainly not have 343bhp - remember topgear with their vel satis 3ltr v6 6 year old car on the rolers had 157bhp yet its makers claims were 210bhp.. a very major service incl new inlet manifold & injectors & polished head managed to get it back up to 207bhp.. so maybe your M is below 300bhp in which case >6 seconds & the poor timing you have tried is pretty worthless.
Instead try 3rd gear 20mph to 100mph or 4th same increment that way its a rolling start and you just floor the throttle and steer - no issue for poor gear changes and engine/transmission damage/wear will be vastly reduced.
Thank you all for your input. I agree with you all in regards to testing it from a rolling start. Eventually I'll be fitting a new air intake then remap on rolling road so will find out what figures its giving out then. I will keep everyone posted. Again thanks for the advice, just bought the car so the last thing I want is a huge bill.
Thanks.
Thanks.
I never had much fun doing 0-60s in an M3. Too much wheelspin, or not enough, or nasty clutch slipping..
It's in its element when you hold 4000rpm in a low gear then nailing it to 8000 and through the gears .. eg 50-70mph roll on. Done properly, frighteningly fast. That's where the fun is!

According to a lot of the forums it puts a lot of strain/wear and tear on the clutch and other drive train related parts. I haven't done one yet, I will do one just to experiance it though.
With launch control may well be worth trying it out.However clearly there will be clutch damage but given its what an 02/03 car.. with 60-80k then given that why not as it may very well need a ne clutch anyway in which case by doing this with the old worn out one then replacing with a fresh example.
That said I'd still not be too happy with a new clutch bill..

It was a 3.0 litre Avantime NOT a Vel Satis sadly. The 3.5 litre V6 Vel Satis (Nisan 350Z engine) has 245bhp standard and an easy 300 with mild Nismo Mods.. :-)
Sorry for the anorak mode but I just bought a Vel Satis 3.5......must be mad :-D
