Since we are talking about engine, I would like to share my experience too.

Got few times when I'm driving, the pedals (brake and accelerate) seems 'disconnected' and unresponsive.  Worse timing happened when I'm cruising at 80 KM/H in a heavy rain on a highway heading to Kuantan, luckily it's for a very short time and there's no car infront of me.

p/s: the engine doesn't stall, just the pedal unresponsive.

So long time no visit here...
Now at SC for 60k service.. will cost me 1200++!!
         

Bro, u expect to drift up to there? I can shoot up to 70km/h using D in exec. But of course la, u need some time to recover the torque after the turning la. For me, S is not necessary bro.

I just went to genting and bukit tinggi on past few days.. but im premium model, so no problem to go up in D mode.. S mode is better.. wont hurt engine la by that certain distance.. just use your S mode and go up all the time.. when down, just put D mode, and engine will auto braking for you..

Whenever going uphill or down hill, I use D mode initially. If I find it is not adequate, I'd switch to S.

Going up Genting, if you are following other traffic in the left lane, D is enough. But if you want to go faster, you'd find that in D the engine would rev higher and then drop to low rev when you release the throttle. So the RPM goes up-down-up-down. That can be very annoying. In such situations use S mode.

In S mode you can drive up Genting at 60 km/h but the RPM stays within 3000 - 4500 RPM.

This is for CFE version.

agreed with sanadi.. when go up, if use D mode, left lane is ok.. but some cars in left lane are too slow.. 30km/h?! S mode mostly RPM will around 3000 or above.. much more constant power for us to climb up faster.. when downhill, D mode is sufficient.

I rarely use S mode on the Preve Turbo as I find the RPMs to be very high in this mode. I have only tested the S mode on normal roads and have not driven the car up to Genting. It seems like the car can be driven up to a practical speed of 80km/h in S mode before the RPMs get too high and the rev of the engine gets unpleasant. But when going up Genting I guess the S mode will be suitable since the speed of the car will be around the range of 30km/h to 70km/h or so.

Man you really sound like a nice guy, but you're being such a pussy when it comes to your relation with your car. Complain about this, complain about that. But when I read about how you actually drive your car, the answer is obvious why you are having those 'pussy problems' with your car which could have been rectified if you actually know how to use your car's potential. All your issues with engine knocking , CVT whine loud , engine rev unpleasant, bla bla bla. You don't even know how to drive your car properly ! I won't even go into details how or why, as it'll take too much of my time.

Anyway, I have driven up Cameron and Genting in S mode all the way, and there was no problem whatsoever till now. Just be smart. Don't pussy-fy your Preve. Although it was made to feel more like a family car, it was never made to be a pussy.

cameron highland i think D mode is sufficient ady.. the slope not that steep.. but genting S mode is much suitable..

LOL.. every driver do have different expectation.. so sure got different opinion lo.. for me, preve are good, not that bad as people said.. no major issue, whining noise is reduce from 0-100km/h.. noticeable at 110km/h & above.. engine knocking i dont know about that ady.. i just feel my preve is ok to drive..
