So, this was a challenge... and there were four of us in the car when we set off at 9am in the morning.
We had to swivel in the Klang jam for a while before hitting NKVE. When I hit NKVE, I set the cruise control at 110km/h and we cruised all the way up to Ipoh, when one of us, had to take a leak... so, we all followed.
By the time we reached Kepala Batas at around 1pm, the car was just about half tank of fuel, clocking 404.6 km. That moment, I was confident that we could reach back Klang with 1 tank of fuel. I went for my meeting, and by the time we wanted to head back, it was already 6pm. I kept to my composure of not wanting to accelerate hard to save the fuel and achieve what I have never achieved before. Believe me, its hard when you have the urge to just want to accelerate and feel the power. I drove slowly and kept to my discipline and with four of us again... we drove back also keeping to the 110km/h speed limit which I set on my cruise control.
On the way back, we decided to stop by Ipoh to have the Bean Spout and chicken rice. I was thinking whether its possible to meet our goal if we detour into Ipoh, which we will move into slow traffic and lots of traffic lights. However, we had nice chicken rice in Ipoh City.
Finally, our stretch back to Klang was again set at 110km/h all the way. By the time I reached back Klang town, the fuel warning light started to beep. I clocked 783.0km with 1 tank of fuel and yet, I had another 110km to go with the balance of fuel in the tank. Looking at the trip computer, I have done a 6.5l/100km which is equvalent to 15.38km/l with 4 people in the car and aircon all the way and back.
This is indeed a great fuel consumption on the 1.6 turbo engine running constantly (95% of the time) at 110km/h.
