SMG E46 325i or 330i

Just came to my mind and was wondering if its ever been done before

Has anyone tried to run an SMG e46 In chumpcar? Some rare 325 and 330 had the option. 

Wondering if it would count for the 75 point reduction as it does have a full manual mode.

Does "SMG" have a torque converter?

Since it has basically every component of the standard manual transmission, plus some stuff to help shift it for you and it was "very rare" it doesn't pass the smell test to me for getting a discount, I'd suggest you keep looking for a different loophole.

 

Kind of like every 3 series car having the winter package for a free LSD.

This sort of rules interpreting is how rule books get big.   Not that one shouldn't study and make sure you're  building the best car the rules allow, but thinking a little about the intent of the rules sometimes goes a long way.   Pretty sure the idea here was if your using an automatic, it is a hit to your performance so we will lower your points.  So using some sort of contraption that happens to shift for you or help you do it is probably not a hit to performance and probably not what the rule intended to allow.

SMG was a transmission for the M3.  No M5X engined e46 was offered stateside with an SMG transmission.  The automatic transmission used in the e46s was actually a GM transmission.  

 

To help the unfamiliar, the SMG was the standard manual transmission with an electronically controlled clutch, a shifting mechanism, and a computer to control all that crap.  For our applications, it should be classified as a manual transmission.  That said, since the donor vehicle isn't on the list, we likely won't ever see it...

Incorrect. Known as SMG I and it was sold in US.

Having twice driven 2 versions of a similar car (E9x in one case, VW golf/jetta in the other), one equipped with a normal pedal+lever manual and one of those fancy paddle-shift manuals (SMG, DSG, Dual-clutch, etc, etc), if an automatic trans is -75 points compared to a MT, the SMG/DSG/etc. should be +25 pts.  Faster shifts, automatic rev-matching on downshifts, no missed shifts, no chance of pushing wrong pedal.  All around better.    

 

Just because a car doesn't have a clutch pedal and has an 'auto' function on the shifter, doesn't mean the transmission is an automatic.  The method of changing the gears doesn't matter, what matters is how the power is transmitted from engine to wheels.

 

Soul/fun-sucking converter, auto.  Clutch (any number, and method of activating), manual.

Every time I take my car up in the mountains I end up with a huge smile and trying to figure out a way to get its drivetrain into some kind of chumpcar. It may look like a quite boring station wagon but with a very nice 1.8 turbo that is easily flashable to 300hp, a sweet shifting DSG transmission, and an awesome Haldex all-wheel drive system it’s an absolute hoot to drive fast.

Easily flashable to 300hp?  Wow, the new 1.8T must be a lot different from my old one!  Bigger turbo but they figured out how to keep it driveable?

I've never driven one, but have a buddy who works at a German Auto specialist, and I remember his comment was SMG was like riding with a teen-ager who you've just taught how to drive stick shift. :) 

All the complaints I have ever heard about SMG (on the e46 M3) was solely about taking off.  I can only assume that the shifting on track would be its real advantage.  Perfect upshifts and no chance to overrev sounds good to me.

Should be case by case or separate line in VPI. The mr2 spyder had a "SMG" but the upshift was so slow it cost the car almost 1+ second in 0-60 and over .5 in the 1/4 mile (https://www.caranddriver.com/reviews/toyota-mr2-spyder-smt-short-take-road-test). on downshifts it blipped the throttle and was good, but overall it is not a performance system. Is the e46 non m3 "SMG" superhuman or average guy when it shifts? the MR2 guys believe its a very similar mechanical system with a different controller that makes the BMW version better.

Disagree about the case by case as someone will come by and "fix" the system to work properly then gain from not having a torque convertor slushbox automatic.

So more weight, extra pump taking power, additional failure points equates to more points regardless of current state of SMG system vs a tradition manual..... Yeah disagree completely.

 

If someone "fixes" the SMG, then maybe reevaluate the vpi of SMG vs non SMG car?????? Isn't this already done with other platforms. Love to see a chump team of all people fix some of the shitty SMGs. Once fixed change the VPI, but the larger car but community as a whole gained.
