If you're concerned about the magazine result's accuracy, don't you think that car companies would just phone them up and demand correction if those magazine's times were inaccurate ?

The bottom line is that M235i 6MT should be able to complete 30-50mph pass in no more than 3-seconds which my car is nowhere near, even the lag-king Subaru WRX STI which is a complete dog below 3000-rpm achieves 30-50mph in 2.8-secs: http://www.autoexpress.co.uk/subaru/...sti-vs-audi-s3

I get 2.31s on the AT in 3rd 30-50mph

Are you sure it was in 3rd ? Did it kick down ? The ratios are different in an automatic anyway.

Yes, it was 3rd.... M235 doesn't kick down in manual mode

[Anthony235]

Take it out of comfort mode...

Did anybody else measure 30-50mph acceleration time in 3rd gear but with a manual transmission ?

I would but being FBO I don't think would be a very accurate reading compared to OEM.

CDV delete or mod is in order on all 6MT.

What do you mean? I thought it had been integrated into the gearbox somehow preventing it from being modded?

It could be. I'm coming from an
F10. It should be something like this.

keep me posted with what you learn!

Why would this make any difference for a 30-50 on an in-gear run?

[amw896]

I'll try this run a few times tomorrow. Are you sport+? I have noticed that in gear pulls feel significantly stronger in this mode, almost like there is less turbo lag or something. I'm coming from an IS350 where it also felt like a dog when it wasn't in ect power mode. Also, pardon my ignorance but in the crazy is a CDV?

it's not that there is less turbo lag, it's that just that the throttle is slightly more responsive kind of inverse exponential instead of linear

i think clutch delay valve

ah! Makes sense, is it possible that messing with the different modes affects the CDV as well as throttle? I might be just placebo but I swear my gear changes are far crisper in sport+ than in full DTC/DSC off mode! I do find the chassis a lot more complacent in comfort but the throttle to me just feels UN natural. I'm not even going to talk about ECO, cuz really, who gives a crap about that mode? lol

Top gear, 30-50 mph: 6.8 sec

Top gear, 50-70 mph: 6.0 sec

For Golf R with manual:

Top gear, 30-50 mph: 10.5 sec

Top gear, 50-70 mph: 7.5 sec

I know it's not the 3rd gear times you were looking for, but you can do your times in 6th to compare...or trade your car in for the auto

The M235 auto times noted above are NOT holding 8th gear (ie top gear) for the run. It's downshifting into the ideal gear. The time includes the kick down and take off. C&D and other mags test in full automatic for these particular tests thus it's very misleading when trying to compare times with a manual which is truly staying in top gear for the run (6th).

If you put the M235 auto in manual mode at 8th gear at 30mph, it's going nowhere. Will the auto even let you be in 8th at 30mph and go full throttle? Sounds like absolutely hell on the motor (super high load). Again, and this is why the mags test in automatic mode because most trannies don't allow this to happen in the first place. They will kick down regardless of driver intervention. This is done to keep from overtaxing the motor, creating detonation, etc. This can be a very dangerous load situation in a turbo motor.

[amw896]

absolutely right, they are definitely kicking down on the auto trans and plus the ratios are crazy shorter (8 vs 6spd). Regardless, I did several 30-50 pulls in my manual today and they were nothing short of pure magic. My old IS350 was also geared super short with plenty of power for city bruising. If I wanted boring ass paddles I would have kept that car but instead I went for pure driving experience....Anyone who thinks this manual hasn't been created by God has minimal experience driving them. yea yea, zf tranny is faster bro - but girls get wetter with men who can handle third pedal thrusting

3 pulls NOT full throttle in sport +. Average time was 3.14 secs. This was in cold temp on winter tires and yes I'm 6MT.

not full throttle? whats the point then?

This entire thread is "what's the point" IMO but wanted to highlight the relative time it took. Point being it wasn't foot to the floor.

I don't know why you'd ever floor it in 3rd gear at 50kph but here we are talking about it.

[SquireGlig]

Torque Pro has a display to measure 40 - 60mph. Not sure if you can customize those values but might be more accurate on time.

[GioM2Comp]

I did about 4-5 runs from 30 to 50 mph in 3rd gear.
My average was 3.2s and my worst was 3.32. I have a stock 6mt.

That's more in line with the expectations but disappointing nevertheless. Even if we generously assume measurement error of +0.4s the adjusted time will still only be 2.8s which is what Subaru STI "The Lag King" can achieve ( http://www.autoexpress.co.uk/subaru/...sti-vs-audi-s3 ). My questions is: where is this vaunted lag-free BMW power delivery from low-revs ?
