When car on P & N mode, step on the pedal and car engine cannot revo more than 3000RPM. [FLX]Don't worry, is actually normal for Proton CVT, this is same goes to Preve and Exora Bold.
What is the purpose of S.A.T? Turbo for saga?[FLX]S.A.T = Stepped Auto Tranmission
Because Saga FLX comes with virtual gears, in before you get your FLX your sales person keep on mention
6-speed is actually after you activate the SAT then will comes with 6 speed (a.k.a 6 Gears). For me this button is use to cut lane with higher revo of the engine. Somehow a bit act like turbo for kids.

Do noted that engage S.A.T will consume more fuel that D mode.
How to make my car more fuel saving?Well I can say that for every car is same. If you can maintain your engine revo more or less around 2000RPM that will giving you best fuel consumption. Of course you're a light footer that should be an easy job.
