I was disappointed when I got 5.7-5.9s 0-100km/h in my 135iA Convertible. (When she was stock). I also did for fun a soft launch with traction control fully on and got 6.6s. So something not quite right here. How are you launching? If driving skills is not the determining factor here then I think its time you put your 135 on a dyno. |

Aside from a couple of minor quirks and bugs, I really do love my new BMW. especially when it comes to performance. I have a 128i steptronic automatic only 230 hp 200 tq (roughly 240 hp and 205ish tq idk) w/ perf air intake and shifting manually in full throttle + kick down mode i can get from 0 - 60 mph in less than 6 seconds... after about 9 seconds im speeding thru 100 mph in 4th. Not something I do everyday.. but was fun popping the cherry after about 2k miles
personally I think how coordinated you are with your foot/driving skills has a lot to do with how good you can really bring out the full potential of your car and where you strategically decide to shift, all of these factors which has a lot to do with how fast you can get from 0 to 60 and overall driving performance. Try different shift points and pay attention to how you are stepping on the peddle. 3rd gear w/ kick down after no kick down but full throttle in 2nd hitting 4.5- 5.5k rpm on 2nd (dont go over 6k rpm you will lose acceleration!!!) thru about 30-35 mph and 3rd from 30/40 -60 on the 128i seems to be the real sweetspot for fast roughly 6.0 times in the 128 the perf air intake really boosts the acceleration around 3.5-5.5k rpms Slamming on the gas is not the fastest way to 60. dont engage kick down right away, wait a couple seconds... you gotta caress the peddle for a second or two and let it slip into the acceleration. One thing I think people forget about this car, is you will not get the best acceleration red lining these new BMWs because their torque and hp drop off dramatically after about 6k. If you keep your car between the 4 - 6k range that is where you will get the best acceleration. Like I said, Personally I can get from 0 to 60 in about 6 seconds with my 128i, and that's not going over 5.5k. Oh and to that one person who claims to be a race car driver / " advanced police driver ". getting high 6's in his 135i... lol? have you ever won a race?

I highly doubt any 128i that is not modified will get to 100 in 9 seconds, the 135i only does it in about 11.5 secs, so there's no way a stock 128i is doing the same

1) less maintenance 2) more reliable 3) 128i has NO High pressure fuel pump, and therefore non of the ridiculous amount of l problems the 135i is having (sometimes even after just 1000mi for gods sake!). 3) far cheaper 4) looks almost identical to the 135, and with a couple of performance upgrades (still far under the price of a 135i) can easily perform as well as any stock 135i |

I agree the 128i is a downright amazing little car for the money. it's the model I planned to get before I found the 135i for a sweet deal. that said, about 9 secs is still way off, considering the Car and Driver test on the car had the 1/4 in 14.5 at 96 mph. I have driven both a lot (my brother's got a 128i coupe, sport, 6mt) and the 135i is way, way faster and it would take a pretty bad driver, imho, in a 135i to lose in a straight line vs a skilled driver in the 128i. curves- totally different story

5) big save on annual taxation (above 250 HP here things are getting costly) 6) for various reasons outside US price difference is much bigger 7) in case of less than ideal roads non-sport suspension is God given (what is not option on 135i and much is better suited for daily driving and believe me difference is vey obvious, although car might behave softer in cornering on high speeds) 8) no turbo effect engine (that I obviously don't like, although it's matter of taste) I don't know how you did ~6 s acceleration with AT + only modified air intake (throw some light on that), but with 80 HP+ tuning I can assure that car is really quick and practically equal to stock 135i with different (better) feel of engine reving in higher rpms. |

My best 0-60 is 4.84 and I can run 4.9* all day long even on bald tyres on a quiet industrial back road. I'm using a g-tech and my car is auto transmission. It's all in the launch. 6.6 is way too slow.

i hit 5.01 on my vert w/o tune, except BMS DCI, so something is VERY wrong with a 6.6 sec run. With JB3 im down into mid 4s. Brake boost till 2100 rpms on DS and go go go go.

Oh bullshit. A car doing 0-100Mph in 9 seconds will be running 11 second 1/4 miles, and you're NO WHERE CLOSE to that. I'd be shocked if you're even into the 13s. The only way you're going to outrun an automatic 135i is if the driver's afraid to put their right foot down. |

Can the 0-60 of the MT be reproduced with the AT in "manual" mode? Does the AT actually respond to your shifting when you want ( MT BMW spec 6.1) adn deliver the same torq? Or is it slushy and shifts sort-of when it wants anyway? For example, I was trying the "manual" shifting in the G37, and man, what a swooshie-lurchy experience that was. I would shift the shifter, and then there was some indeterminate amount of time, then the gear would shift with a sync of some sort (poorly in my opinion) , and then kind of lurch. I mean, to me, it was poor. The plain automatic is OK.
I'd be happy with a 128 if, with a couple reasonable mods, I could get it under 6 sec., in the "sport manual" shift mode. Raceman says he can get below the mid 5s (I'm interpolating here) with his more seriously modded 128 (including ECU tuning, which I don't know of anyone doing here in the state?) |

Can't say the same on the 328i loaner that I had recently. Don't know what year it was but it reminded me of your experience with the G37. Lots of delay and very mushy feeling. |

[quote=ru55;5773170]It's rubbish....my stock 135i will never do 0 - 62mph in 5.3seconds!!
(And before anyone says, its not my driving...I am a qualified race driver and advanved police driver) Best 0-60 time i've had in my 135i is 6.6 sec[/quote I used my Escort G Timer soon after getting my 135 and got just over 6 seconds without even really trying. I haven't attempted to repeat this, only because it isn't really that important to me. What were you using to do the clocking? |

You have an intake only, and without dyno proof I doubt you're getting much HP/torque gain at all, and in some engine applications, HP/torque go down with many of these intakes without additional tuning and/or exhaust mods. You talk about "sweet spots" and knowing when to shift? You drive an automatic. How much do your magical upgrades cost to bring your 128i to easily perform like any stock 135i? What are these mods you speak of? Do you then realize that with only about a $400 "chip" you'd be spending thousands more to still be behind a 135i? BTW, you said about 9 seconds, but to you that must mean that 12 seconds is "around" 9 seconds right? You sound like a young kid trying really hard to believe that somehow you can make your 100lb ft LESS 128i as fast as a 135i with just a larger intake tube and your mastery of operating an automatic trans. |

I'll race for Pink against a 128 with intake, unless your few minor mods are a turbo upgrade or a NOS kit.
If that is the case, I'll just have more fun laughing at you Skill and automatic in the same sentence? Sorry, I am a n00b in driving an auto, please enlighten me. Sure, an auto on a 135 will perform 0-100km better than 90% of the manuals but giving the same auto car, how big of a difference could there be between drivers. |

Explain how multiple reviews have gotten the 135 to do 4.7-4.8 second 0-60's. I has been known for awhile that even BMW's claims are modest

I spent over 2 hours driving w/a 30 year field tech employee w/BMWNA, and he told me that the 135i AT was faster than the 135i Manual. He knew more about BMW's [and other marks] then anybody I have even had the grace to meet. I have no reason to doubt him.
