Fuel Economy

I can't see the car doing better after it breaks in, but if it does this FE could get amazing!

Wow that's really good. Congratulations.

4.9 liter??.. this car should be between 5.5-6.9 l/100km how did you achieve that??

I drove a long distance going 80-90km/h on country roads with no stopping. About 250 kms worth. I also have a 52km commute over the 401 and very rarely make short trips with the car.

It also included one 1 hr traffic jam getting out of Toronto though, but I go easy on the gas, basically never brake and the a/c was used very rarely.

I did inflate the tires to 40psi as soon as I got the car, but that's the only thing I do besides taking it easy on accelerating. Every day I see people fly by me only for me to pass them later as they're stuck in a slow moving lane, so I don't have the desire to punch the gas any longer and I think that's the biggest contributor to this result. Slow acceleration and consistent speeds.

I am aware there are errors with any fuel mileage calculations, but I did drive 707 kms before I filled up with just over 34 litres I think it was, so error rate should be somewhat low.

I was shocked to get 4.9, but some people get less than that consistently, like Bailout.

Your location shows "Toronto", so in order to get that kind of FE on the 401, either your commute is at 2am or you weigh less than 10lbs or both

The 401 is one of the most conjested highways in North America with average speeds during rush hour of >40km/hr. I can't believe that any driver of average weight can achieve 4.9L/100Km driving the 401 during the day

My Yaris is automatic, I commute from Markham to Toronto daily (40Km), my tires are at 42psi, I'm slower than 75% of cars, accelerate slowly from stops, I coast down hills whenever I can (my faves are leslie southbound and bayview south @ pottery rd), limit my use of ac, there is no extra weight in the car, coast to all red lights and stops, I only take one short 10Km trip each week to grocery shop, I don't idle, I don't warm up the engine in the morning, etc.

YET my best FE ever was 5.9 (575km on 34L). Your 707Km on 34L is 23% better than that. Either I'm missing some voodoo driving secret or, with all due respect, you're not telling us all the facts.

My best tank is also 4.9, to and from the Sea-to-Sky Highway with two passengers, speeds ranging from 30 to 80 km/h, lots of crawling up slopes and riding down the other side with DFCO.

Now I'm consistently 5.2 in all city traffic.

5.2 in city traffic is amazing. If I could get near that it would be awesome.

DFCO supposedly only works on autos in 3, so it's harder to use, but whenever I'm coasting below 80 I try it.

I wonder how the car will do for mileage in the winter around here.
