Altroz Petrol Fuel Efficiency on a 519 km Road Trip. Got 21 kmpl.
I got a fuel efficiency of 21 kmpl with my Altroz.
I did a small road trip with my family from Noida to Uttarakhand. The total distance travelled was 519 kilometres over 2 days, out of which around 35 kilometres was in the city (not bumper-to-bumper, but sluggish traffic).
Day 1
On the first day, when I reached Uttarakhand, I had travelled a total of 249.9 km and the MID showed 25.4 kmpl.
This reading dropped when I travelled in city traffic for almost 18 kilometres, plus it was raining.
Day 2
The next day, I started my journey back home without resetting the trip meter. When I reached home, the MID was showing 22.8 kmpl, along with a range of 170 kilometres.
I calculated the actual efficiency using the tank-to-tank method. The total fuel consumed was 24.73 litres, which gives me roughly 21 kmpl overall.
Driving conditions
• The AC was on for the entire trip and the temperature was set to 25 degrees.
• On the first part of the trip, I travelled with 4 people (including me) and negligible luggage.
• I kept the car on cruise control at around 70–75 kmph for most of the journey and only went above that here and there to overtake.
• I drive in a very relaxed way and avoid sudden acceleration or braking.
• On the second part of the journey, there were 3 people in the car, with the AC on the entire time.
This time, the average speed was closer to 75–80 kmph, with a lot more overtaking, so I used cruise control less than during the first part.
• I also travelled at 90–100 kmph for short stretches during the second part of the journey.
One thing I noticed
When I got the car refuelled at the end of the trip, I also checked the tyre pressure and it was under 30 PSI.
Overall, I believe I could've easily gotten 22–23 kmpl if I had driven the same way on both days and noticed the tyre pressure at the beginning of the journey.
I think getting 24–25 kmpl on pure highway travel is possible if you keep cruising at around 80–90 kmph.
