Let me start by saying it's been an ongoing issue for about 6 months, both in hot and cold weather, drought and rain.
I have a 2007 1.0 Turbo Smart 451 with around 120,000mi on it.
It is a European model as I live in Europe (I'm here because every European Smart car forum isn't working or doesn't allow new registrations for some reason...).
I did find a similar issue on Smartz, but it was missing an answer.

The story goes like this:
Every time I push my car to the redline stage the clutch actuator just stops working properly.
To go into detail, it starts dropping the clutch like mad, in a sense that as soon as I press the gas pedal ever so slightly, it instantly drops the clutch and kicks it into gear. As you can assume, this does cause a considerable drop in the revs, as it's like dropping a clutch instantly in a manual transmission car. As it causes an incredibly violent jerking, I'm concerned about potential damage to the car as well as it's quite uncomfortable to drive, especially in traffic as when it drops the clutch so quickly it also accelerates quite quickly as if it's being launched. There is seemingly no fix for it you can do on the spot. The only way it fixes itself is completely random, i.e. being left overnight or just plain while driving. It's most noticeable when starting to move as shifting from 1-5th gear while driving is usually like hitting a pothole(while the problem occurs, but when stationary and beginning to move it's like being rear-ended by a 69' Charger.

My main concern is how shifting gears or starting to move works perfectly smooth usually, after pressing the gas pedal the car slowly brings up the revs then slowly lets off the clutch, but as soon as I redline the car it breaks for a certain amount of time and like states before when stationary and pressing the gas pedal the car jerks violently and drops the clutch instantly almost stalling the engine(which for some reason has never happened even though the revs do fall to 500 when it does occur which is quite low for a gasoline engine).

I'd really appreciate it if someone knows a possible solution or has encountered a similar problem.
And no, not redlining it is not an option. If you think traffic in the US is bad trust me, it gets a lot worse in Europe due to the violent merges that need to occur as no one gives way due to extreme traffic congestion. Getting another car is also not an option as I really like my 1.0 Turbo, especially the heated seats, and I just bought it as it was the ideal choice for an 18-year-old computer science student.

Thank you for your time,
~Dominic from Croatia馃

鈥ominic鈥mart didn鈥檛 get here till 2008 so that turbo model never made it to US鈥ut you can try the Canadian club鈥hey had them long before us


if I had to make a guess I鈥檒l say your clutch/disk/pressure plate is/are gone

jetfuel鈥ood luck with your car and studies
Thank you for the reply, I have tried that site however the registrations have been down for some time now. I'll have the mechanic check the entire clutch when my next service is due. Thank you!

Turbo or not, it seems to be common among Smarts. Miss Mercedes has posted about it several times (do a search). She has found that the car has to "unlearn" that you want to accelerate fast, hence the period of time. I had the problem once and it did not seem to go away so I replaced the clutch actuator. no more problems, however I do not have occasions to floor the car (it seemed to happen after I floored it to red line), I keep below full throttle. I suggest you drop Miss M a Personal message from her profile page and ask for her input. Miss Mercedes
