yea. i was thinking this too

noise nvm lo

OPEN THE WINDOWS SAFER ?

I am not too sure about this one, because another factor to consider is lift. Although the following video does not specifically talk about opening the windows but understanding the basics of crosswinds and area, I think opening the windows will actually aggravate the situation further at high speed.



The best option at the moment is reducing speed to increase the downward force of the vehicle and hence stability and control of the vehicle. I will try to find out more information about MB Crosswind Assist, surely we can learn something valuable from there.

Lol... finally someone come to sense and use the right word "lift". Basically almost all road car has lift aka "negative downforce".

And seriously everyone please keep both hands on steering, and sit at appropriate distance where 3 + 9 o'clock position with elbow at 45-90 degree bend.
I've seen so many drivers sit so far away, it is downright dangerous. Impossible to have good control of the car.

Sit properly, hold properly, cross wind is not that hard to compensate. When necessary slow down.

** Gone are my days with old Corolla with soft plastic like chassis, eco sponge tyres, doing top speed 190km/h floating with cross winds near KLIA.
Was rushing to attend customer escalation as most junior guy (with least valuable life as bean sprout) in the team. Not dare to do that anymore.

Gonna agree with this, no matter how good is your car. Crosswind is always a problem, and there is no actual way to reduce it; even aeroplanes have turbulence. The best way to over come is to be prepare for it and slow down if need

I have never considered lift before, not engineer mah. All I know is forward thrust dan downward force. Adding into the equation crosswind, I know things can get pretty screwed up. That video brought to light many things I had never even considered before. Now arm with better knowledge, I will be looking into ways of making my ride a safer one.

While we would have driven at crazy high speeds when we were younger, I am sure we have not encountered strong crosswinds to really endanger our vehicle. I personally have not encountered a dangerous crosswind situation either but when ktek experienced it, it was a chance for me to learn especially when ktek mentioned crosswind hit from left and then right or was it the other way round ?

The most dangerous situation I've ever encountered on the NSE is hydroplane. No matter how perfect the sitting position is going to be, the vehicle will have a mind of its own when it starts hydroplaning. I am extremely lucky during hydroplaning on the fast lane, the vehicle decided to go to the empty lane on my left and not into the road barrier. Since that incident, I don't dare do jack shit no more when it's wet.

Herein lies my problem, I am so completely focus on the expressway traffic and without a row of windsocks along the area prone to crosswind, I wouldn't know where the crosswind prone stretch begins and ends. In my mind, being prepared for it means to lower one's speed before entering the crosswind stretch. The only time I think about crosswind is when it appears on Lowyat forum.

When ktek said he experienced crosswind at Sungkai area, I don't even remember seeing any warning notices or windsocks along Sungkai stretch despite traveling KL-Ipoh so many times.

The best would be PLUS erects more windsocks along the expressway for maximum visibility for it's road users OR build wall along those stretch. Initially when PLUS started planting Teak trees all along the expressway, I thought they would grow up to be excellent wind breakers against crosswind but after seeing how those Teak trees developed overtime, it's very disappointing indeed.

You don't need to pay much attention to those windsock, if you feel it, you should slow down and keep your car in your lane as much as possible. Car/Trucks passing you or you passing a vehicle also can cause crosswind.

Tried it before in stock Axia at 160km/h going down to Malacca. Road was quite empty at that time as it was a weekday, and was on the fast lane. A sudden crosswind pushes the car to the right, and the only way to overcome it is to slow down to have better control of the car and grip.

Lighter car = More prone to crosswind
Heavier car = Lesser
Tank > 0 Crosswind

I didn't know if crosswind is also proper description for turbulences caused when 2 vehicles passes too close to each other. I thought it is call something else in physics like Balotelli's effect or something. That I kena before after picking my wife's new car from KL and when the express bus overtook, the vehicle became unstable even though I was going like 80km/h only. Since that incident, I don't travel outstation with that vehicle anymore. All I could see was the car was drifting closer and closer to the side of the express bus while I was trying to slightly turn the wheels away from the bus. Bus lalu already, no problems whatsoever.

The best and cheapest mod of all

there were no windsock/ signage at the place i kena.
but other section got sign. haha

last saturday i went again while less affected, quite safe as usual.
maybe car was empty or wind is weaker

see see

from kl to pg, south heading north

Sorry what is the time stamp in the video you kena crosswind ?

OK better still don't reply yet but see if forummers can guess what is the exact time stamp you experience crosswind, cause I can't. Lai Lai tikam tikam ...

actually louder noise could be heard and noticeable traffic movement.

Wow that Altis GR so fast and unaffected by cross wind huh? First time see this gen Altis 1.8 drive so fast, usually they drive middle lane slow slow because of weak engine...

how to detect 1.8 or 2.0 specc

altis gr sport should be the most current one kan

i think only available in 1.8

2.0 no more already
