Hi, so I purchased my Proton Iriz CVT 1.3 Standard exactly two months ago. Had my first service weeks ago.
Driving through the city road is great. Smooth and easy. But there's a downside when driving downhill.
See, I drove my Iriz back to my hometown, it's about 80km from the city. The road that I took has about 50km going uphill and 30km going downhill. What i noticed was that when I drove on a long downhill road, the RPM shoots up to 3, and I'm just at 60km/h. On a steep road, brake is applicable, and the RPM can be tamed because of the brake, but when on a long (but NOT steep) downhill road, the RPM shoots up. I can use the brake to tame the RPM but it would be ridiculous especially when it's not a steep road and when there are cars behind because it would slow down the car to 50km/h. It made me think twice to cut in line whenever I need to especially cutting an 8-10 wheeler truck who uses the same road because using L gear at top speed would shoot the RPM to 4.
Does this have something to do with the engine braking system? The only solution we have at this moment when driving through a long downhill road is by maintaining at 50km/h, without much pressure on the accelerator.
It made me think that this car is not made for the hillside.
