See.. from my office in Subang Jaya to KLIA car park took us about 42 minutes, I used the auto cruise function and cruised at around 100kmph cause we were early then expected time. Travelled 47 km from Subang Jaya to KLIA and average speed = 67kmph. And see ?? see ?? 8.8 L/ 100km leh !! That's the best I could go already hehehe
