Ever since I started driving my current Honda Stream, I’ve never been able to get any fuel consumption reading below 9.0l/100km (at least not under “measurable distance in reasonable driving conditions”). But this is what I got recently: 7.9l/100km. I was really happy. It wasn’t even wholly smooth going highway driving conditions. There were some bits of city driving, although much of it was indeed on the highway.
The fuel consumption meter is sure to get many drivers super engrossed on saving fuel. In fact, I think the fuel consumption meter kind of acts as a device to improve fuel efficiency. Some day, I guess all cars will have this by default, along with various options to get instantaneous readouts, average over 10 minutes, average since engine start, average since tripmeter reset, etc. Yes I know some cars have various ways to compute the readings, but I don’t think they have all the different computation variants together.
My Honda Stream’s fuel efficiency hasn’t been that good. It’s probably due to the bumper to bumper traffic that I get stuck in all the way to work, and part of the way home too. It’s far worse than the ordinary city driving. I don’t know what ultra-urban means, but I imagine my bumper to bumper traffic is also worse than what ultra-urban is. I think someone should just come out with a simpler way to convey fuel efficiency numbers so that we can easily share and compare between cars, and lay people can easily measure their own and meaningfully compare and “verify” the figures. In case you’re wondering, my “bad” fuel efficiency is like 11 – 12l/100km.
I pushed up the pressure in my tires recently. I’m not sure if it will have a measurable difference. I will see in my next tank full, when I’m back driving my usual routes.
