None. Sill brand new, just done over 1,000 km.
The 2.5l engine with 180hp is powerful and able to do 110kph up a fairly long and straight steep incline, without shutting off its overdrive. (The shift is 4-speed auto with overdrive.) And I did not really floor the pedal since I am overly cautious as the engine is still not 'break in' yet.
Doing almost as good as my previous car which is a Ford Ranger 2.5 intercooler diesel up this particular stretch of road. Most other cars would gradually drops down to 60-80kph with the pedal to the floor.
I found the car a bit bouncy and rolls a bit on rough, uneven road, while others who tested it found it okay and acceptable. Maybe I'm used to the manner the heavier Ford Ranger with stiffer suspensions behaves...
But with a full car load of driver and 4 passengers, the car drives better with less obvious bounce and rolls. And the drive is superb with the powerful 2.5l engine; with no comments of discomfort from the passengers.
I don't think you can have review on any car if its less than 1000km, what's there to review when its still new?? I am sure even the lousiest car sold in the market won't find anything wrong before 1000km or even 5000km.
You'll be surprised. If you buy Malaysian made Proton, you should make an appointment with the service centre as soon as you collect your brand new fresh from oven Proton.
