E93 Buang-ed (Skidded)

[Eggie86]

Where exactly is this area guys? Along NKVE, Shah Alam exit?

Judging from what many of you have shared here, seems to be quite an accident prone area, even at such low speeds.

Scary! Drive safe guys!

when a car loses control/acts funny......its mostly due to the driver. Sorry.

for ur case, if the 2 corners are the one we know of.....southbound exit NKVE towards Shah Alam/Jelutong - the 2nd right hand switchback ( corner ) could be the trickier one as its tightening up plus going up the bridge.

frankly these corners are not particularly challenging, unless u are at a very high speed.

so, my question for you is - were u braking hard in the corners? if you are, then my 1st statement applies.

Drive safely - all year round.

as i recall ...i was not on a fast speed..and no hard braking as well...! if i did any hard braking, the car would have skidded even more right? hmmm...very puzzled. ...

i think i will be taking my car for a checkup this weeked.

Thank you so much to all the sifus here to help help and also advise ya! appreciate a lot ...

if got any outcome to the inspection ..then i'll update you guys ...

wahhhhhh!!!! i tot only e30 is tail happy car...!!!!

 

[aoch88]

Topgear says R35 can handle all corners without problems and guarantee won't skid. Maybe we should try that car on the same stretch and see

Definetely oil bro put on purpose by tow trucks. How do i know? I was in one similar position in 2004 on d way to klia from subang , d ramp leading to d klia toll. Was wet, slight drizzle going ard 90 kmh, tapped d brakes lightly n i mean lightly, n could no longer control d car. Next thing i knew, d car had hit d side barriers. Luckily no other cars or bikes closeby when it happened. One minute later a few tow trucks at d scene of d accident. I was driving an e36 325 then. I now have a 335 n it is one of d best handling cars i have driven . So it is not driver error, but oil on d road i m sure. If a bmw cannot take a 60 kmh corner, then v may as well all drive locally made cars. Unless of course u r on slicks or semi slicks on yr 335.

 

[astroboy]

What puzzled me was all other cars passes by that stretch at the same time has no issue, why only this car?! If oil, all tapao liao!

is there a possibility that the owner accidentally diabled the ASC control?

Not every car on the road has ASC la.. even if yes, how about these other car that passes the stretch with similar speed or higher speed but no drama? Hmmnn...

that stretch is famous for what you just mentioned. I too saw a couple of years back, a salesman driving a mercedes to be exhibited in KLIA skidded and hit the barrier at the side of the road. And I too had a chat with a klia limo driver, he also say that it is due to oil on the road.... and now the road is still dangerous though it has been laid with the rough red rubber-ry surface... please be careful while driving there. brake early, and ease your way through the corner.

+1 on Jules first statement...

its 95% driver coz the input comes from the driver and generally 5% mechanical...car dun move or loose control itself...regardless of oil no oil...general speed limit for Road/HW-exit/ramp is 50kmh...driver decide to push the limit or not...its his choice...sometime when you less expect it to happen this is when you did not concentrate and bad things happen without knowing the reasons on why it happen...

driving requires 100% concentration and boundary/limit must be observed at all time...

Actually I have a question on how DSC works. Assuming the road condition is good, no oil, etc so does it mean that even if we try to take a sharp corner at a manageable speed, we just have to keep the speed without stepping on the brakes and DSC will kick in to prevent the car from skidding?

DSC is actually a very complicated system, working on very simple logic, and that's the constant monitoring of wheel revolution count for each wheel, in relation to each other. If certain wheel is found to be spinning fast than the rest of the wheels by certain percentage, certain interfering reaction will take place I.e. Selective wheel braking to improve situation, if fail, cut engine output. Some maps are embedded into the system as a definition of what to intercept and how to intercept. The amazing part of the technology is the turnover or reaction time. I was told we are running a fiberoptic network in the car where information is flowing at lighting speed, same goes the reaction time.

 

[t2ribena]

AB, the DSC is not run via the fibre optics...only the Airbag system (partial) and the multimedia system (MOST) currently...

 

[BMW520]

From my experince (few skid before in different corner or even u turn on wet surface), it depend on wat tyre you use. Even new tyre also can skid if ur tyre is more on synthetic rubber. Try not to accelerate when taken corner as BMW are RWD. I learn from few skid experience.

Thanks Astroboy for the great and useful explanation. These are the qualities of what OM are supposed to have good knowledge and not spams

[fabianyee]

if car start to oversteer, don't BRAKE AT ALL, countersteer to point it straight. Braking, even the slightest tap will send the car spinning like a block of ice... Been thru that once long time ago in a FWD... Was still relatively 'green' back then as a driver. But I have since put a mental note not to brake in an oversteering situation.

FYI, it's very easy to correct an oversteering FWD, just full throttle and countersteer. The front driving wheels will pull the car to the direction you're pointing with the steering. Did this exercise during HPC instructor's Advance driving course at the Proton test track some years back. with my little drifting and go-karting experience,no issue controling the car every time the instructor pulled the handrake while I drive in circle on the wet skidpad.

As for correcting an oversteering RWD, it's trickier to perfect. Counter too much and the car will fishtail. and if it fishtail more than 2 times, chances are the car will end up in a spin. But practice makes perfect... After a while, u'll know exactly how much to countersteer to straighten its course of direction...

 

[aoch88]

Good information there fabian Btw, isn't those powerslide/drift is about counter-steering/over-steering? I would also like to learn how to do it, lol.
