PE fuel consumption is higher than competitors in its class and range. But it depends on how heavy ur foot is too.. Some people I know have complaint to me bout their cars FC very high eventhough they dont go more than 80kmh/110kmh blah blah blah.. But when u see the way they drive. When from stand still or slow speed they will accelerate harder than F1 cars till they reach like 80kmh then they become so light footed to maintain that 'slow' speed.. Furthermore they dont keep a constant acceleration on thier car but like when the speed go below 80kmh they fully press the accelerator to bring the car back up to speed and then they release the accelerator totally when it exceeds their so called 'personal speed limit'. The constant accelerate/deceleration will cause ur FC to go way higher than driving at the constant speed and taking gradual acceleration and braking earlier rather than heavy braking when ur car is near a red light etc.

Persona is the old one and PE is the new one loh.. Just facelift with some minor tweaks like dual radiator fan. Mostly cosmetic enhancement. For better FC choose persona that has IAFM, cos they reduces the torque dip at low RPM thus giving u better acceleration in city driving.
