Which driving habit consumes less petrol in 50 km expressway run?
I have Toyota Glanza, which has Suzuki 1.2-litre, 4-cylinder petrol engine. My query is regarding fuel consumption on a 50 km expressway stretch that comes in my route, considering the visits are occassional (1-2 times a month) and not daily. Which option should I select?
- 60 kmph cruise control (Gets 30kmpl on MID by doing this)
OR
- General driving fluctuating between 80-100 kmph (Gets around 20 kmpl on MID on doing this)
My Confusion : Option 1st have longer engine running time due to slower speed but it will be at lower and fixed rpm. Option 2nd, where engine running time would be shorter due to faster speeds but rpms will fluctuate and will have overall higher rpms.
Considering time is not a factor for me. So, which option will consume less fuel?
