When I was upgrading my car last year I seriously considered a 2007 335 coupe. I liked the look and power, but the driveability at low speeds was the ultimate concerned that shied me away from this car. It seemed like there was not enough play on the throttle, which made it seem like it was on or off. I was looking for power when I wanted it, but not at every stop sign in the sub. I ended up getting a CPO 545, which I like. Basically refined power.

Well, I have my car in for service and the loaner is a 2008 335 coupe. This car is WAY better. The torque is smooth and responsive. They basically addressed my exact concerns. Its almost like BMW reads this forum. I wonder if this is pure software, or if they reworked (or changed) the transmission?

I sort of wish I had waited now. Maybe next time.

Sold my 07 335 MT for a 08 335 MT and did not have this problem with either. Throttle response was smooth at all speeds and all gears. In fact, one of selling points (of many) was it's responsiveness in all gears at just about any RPM...low or high. Sorry you switched...must have been an issue with just that one.

WHY :confused

Went on military deployment to Germany. Heavy discounts to service members overseas plus tax free (state dependant *I think*) and free shipment to the US when I return. http://forums.bimmerforums.com/forum/showthread.php?t=830215 (http://forums.bimmerforums.com/forum/showthread.php?t=830215)http://forums.bimmerforums.com/forum/showthread.php?t=806372 (http://forums.bimmerforums.com/forum/showthread.php?t=806372)

I'm talking about the automatic transmission. I had one as a loaner and drove a 4-door as well. This issue was there for sure on both. I couple people at my office drove both cars and agree.

One more thing, this 2008 is the Xi. I wonder if that is a different transmission?

I have an 08' coupe and feel like I have a similar issue to the one you brought up. The car is very fast don't get me wrong, but there is definitely a delay between when I hit the gas and when the power kicks in. So either there is problem with my car that i'm not aware of or those who said the turbo lag on these cars was unnoticeable have lied.

This is my first turbo car so maybe i'm not used to it. To those who have said the turbo lag is unnoticeable, do you mean in relation to other turbo's or in general?

You thought the MT drove smoother? That really doesn't make any sense, but as long as you feel it does.

Yes, that is Marketing and Fanboy hype. Any car with Turbos has turbo lag. The 335 is no exception. It DOES have less turbo lag than most other turbo'd cars but to say it has none is a flat out lie.

I'd say if you think that go drive a WRX and feel what lag is. All cars have a lag in them.

I don't understand, were you agreeing with me or disagreeing with me? The two halves of your post seem to contradict each other.

All cars have some lag in where you push the throttle and where you feel a reaction.

The 335 is very close to NONE. If you're in 6th on the freeway and need power there is no boost lag, say like in a WRX where if you're not on boost at high RPM you have the power of a kia.

Agreed with all those above.. if you have turbos, you'll have some sort of lag. But in our 335 E92s, you'll barely feel it. Go drive an older single turbo Eclipse and you'll really feel the lag.

I'm not arguing that the 335's have less than other turbo cars, just saying that you cannot say it has none.

Coming from only driving NA or Supercharged cars, I notice the lag. It is around a full second +/- depending on your rpm's.

I seem to be the only one who understands what you're saying and I couldn't agree more.

Yes the lag is better than most turbo cars.

Yes the turbo lag is still very noticeable.

My original post wasn't really about lag, but how the throttle gave you too much too soon (meaning the first 1/8 of an inch) on the 07. The 08 has a smoother feel with more throttle movement. This is me though - I'm picky.

The dealer said this was probably because the 08 was a Xi and distributed th power better, but I suspect its just a series of refinements all combined.

These cars are tough to drive within the speed limit. I had it for a little over two days and did get a ticket. It wasn't for 100, but 51 in a 35. Its tough to go 35 or 40 in these.

You mean Vacation! ......Deployments are the other places we go!
Oh, BTW, yes, it is tax free and yes they do ship it for free but depending on what state you go to.. there will be a nice,
heafty tax awaiting you. I found that out when i was stationed in germany (after I returned to CONUS from a real deployment)! Good luck!

My 335xs coupe is my first BMW and my test drives were months ago so I have no frame of reference. I am overall very happy with mine but I have been taking it easy during the break in period per the manual.

When I start off it seems to hesitate, almost like the engine dies and then catches itself. I am not pressing hard down or rapidly on the accelerator as like a poster above mentioned I do not want a jack rabbit start at every stop sign/light.

This hesitation may be the transition from the turbo first coming on. I had my CA drive it and he said there was no problem with it.

I come from Turbo too, and maybe people have different definitions of what lag is. I actually think the "delay" you feel, which has been described before isn't as much lag as a computer control slowing the reaction.

I lag to me isn't that delay, but you hammer the throttle and you don't get power until a set RPM. In my car there is a slight delay then full power. six and one half dozen right?

This is the first i'm hearing of computer control slowing the reaction. Can you give a little further detail on that?

There was some post somewhere. It's when you're in a gear, this is in MT, and you apply throttle there is a noticeable pause from when you hit the gas and when you don't. I don't think this is a boost issue because all engines make some power when off boost (and realistically if you're at 3,000 RPM it's making boost). It seems to vary how you apply throttle. When I "roll the throttle" on it seems to not be an issue. When I floor it that's where you can feel it. WHich is why I think it's an MPG/emissions function. Similar to how cars hold throttle when you rev the engine these days.

Lag, to me, is when you start off and you don't have power until a certain RPM, again a WRX has this. If you start off without a full throttle start you don't have power until like 3200 RPM or higher.

This is interesting and you may be right as you explained exactly what i'm feeling. Maybe it's not the lag afterall (or maybe a combination of this +lag), i'm going to try to find out a little more information on this. Thanks for the response.

I payed attention attention today just to see and you can feel both depending on how aggressive you are with the throttle. Slam it on and there is a definite "no reaction" and if you roll it quick you can feel the slight lag as the boost builds, but it really shouldn't be off boost at 3,000 rpm.

There is a little bit of "boost lag" but not what I'd call lag from other FI applications.

I don't believe that turbo lag is what people are feeling when they first step on the gas. It's actually delay in the "drive by wire" system that controls the throttle. Notice that when you first step on the gas, the engine does not immediately rev.... that's the giveaway. Turbo lag would be noticed more in the onset of acceleration. If.. when you accelerate it seems lazy until you suddenly feel that kick from the turbo. I didn't feel anything like that. Power delivery was flawless.

I think BMW set up the drive by wire system this way to smooth the throttle sensitivity out. Otherwise, people would be leaving strips of burnt rubber all over the place with a 335i. I expect to receive my new 335Xi coupe in 3 weeks or so but after reading about this topic in the forums, I looked for it when I test drove the car and I definitely noticed it, but only when starting out from a stop. It seemed like more of a safety feature to me to smooth operation and prevent unintended acceleration.

just my .02

:D

15 more miles to go to 1200! Then I can be more aggressive with the throttle and see how much lag or drive by wire dampening there is.

I have been driving like your old granny, but this car may get me into trouble if I do not watch when and where I launch.

I think with an xi I will not leave any layers of my tires behind, is that correct?

Immposible to spin the tires in a xi, Ive tried. Not even in the rain, and barely in snow.

Impossible to spin a STOCK xi you mean :D

Well if these tuners they are putting on the xi will get that bastard to spin em, then holy F I need to get me one.

Spin them or not if you love power you need to get one anyway. I just installed the SSTT which is probably the least powerful of them all (but easiest to install/uninstall by yourself) and all I can say is :eyecrazy!! It makes the stock 335 feel like a 328. :)

I believe the recent posters are on the right track. It sounds like the delay you experienced is either part of the throttle mapping or the transmission. I believe that the system is designed to adapt somewhat to your driving style, so driving a loaner or demo car may not be representative of how the car you own would work. I believe the computerized adjustment for the car that you drove may have been representative of drivers who did not match your style. I have a MT and have not noticed any of these complaints. This engine is widely heralded for its lack of turbo lag due to its 2 small turbos which feed three cylinders each.

I also have a manual transmission but have noticed what is being described here. It has been brought up several times here and over on the e90 forums with many MT guys having the same "issue". I believe it is correct though that it has something to do with the throttle mapping and not the turbo lag.
