Fuel Economy

[dj92]

I got about 6,5l/100km (36MPG) with the last oil fill (5W40; nothing else was available), now I put in 5W30 (the manual recommends 0W20, but I'm driving at rather high highway speeds (140...170km/h) (not only but also to let the fuel contents in the oil evaporate) and I want to reduce the engine's wear)
I'm driving about 20km per day through town and 2*80km (50mi) highway about every second week.
It's 8...9l/100km on highway and ~6l/100km in town.
I'll report how the values develop ;)

I didn't see a direct impact on FE yet, but seemingly the engine can keep up turning at load points where it would give up before.
My new highway speed record is 115,5MPH now (remember, I only have a 5spd MT) :D

I've just done my first fuel economy calculation, the most exciting part of owning my Yaris! Mine is a 1.3 litre 5 door hatch with manual transmission. The fuel gauge started flashing at 610 km, when I filled up it took 37.5 litres. That's 6.15 l/100 km, or 38.25 MPG. Have followed tips on this site, ie. DFCO, pulse and glide, 36psi tires, timing lights etc. I hope to get a better result next week as my first tank included a lot of highway driving, which I suspect the 1.3 is not so efficient at.

My Yaris is getting pretty decent fuel efficiency. My Fuelly signature gives the latest estimate of basically 40 MPG in USA measurements. This is 7.1 litres per 100 kms or 17 KPL. I think these conversions are correct since I Googled them.

7.1 liter/100 kms = 33.12881455399061 US MPG

I bought my yaris hybrid in feb 14. I have over 19000kms on it now. Fuel economy at 100kms motorway driving is typically 55mpg (imp gal). I got 64mpg at 80kmph. No where near the claimed 80mpg (imp gal).

First, hybrid car in general and this one in particular are optimized for city driving. Yaris hybrid is known in USA as Prius c (I guess c for city).

Second, Euro fuel efficiency tests are too optimistic and not real life. US EPA tests are closer to real life. Fuelly is as real life as it gets.

Be warned, this forum is very hostile toward hybrid cars. Too many folks here have a chip on their shoulder.

welcome, welcome, welcome!!!

its nice to see you can get the YARIS hybrid where you live. we don't get that here. the Prius C is sold here, which is very much a prius in looks/style, though built on the same platform.

many here were hoping we would get the YARIS hybrid, but we didn't.

at least someone can get a YARIS that is a hybrid rather than another version of the prius.

yes, I agree the hybrid strength is in the city, though the vast majority that I see are cruising the highways.

It is all about changing the way you drive. You cannot drive a hybrid like you drive a normal car and expect to get the advertised gas mileage, you have to totally change the way you drive.

You almost have to totally re learn how you drive to hit the great gas mileage numbers.

Oh, and show us some pictures.

btw, I can almost get 55 mpg imp in my Yaris. Hybrids are terrible on highways.

I didn't fully believe all of these 40+ MPG stories with 1.5L gas engines. I did little to build my FE other than watch my MPG numbers on my dash, and drive between 60 and 65. I averaged 42.4 MPG on a 250 odd mile trip on I-65 in Ky. (Right at 125 miles and back) I wanted to go faster but so enjoyed seeing the MPG AVG stay so high. I make this trip fairly often, so I'll soon have the chance to try for better. With these miles and a bearable car payment, I am glad I didn't go for the Hybrid.

I was also skeptical at first while I was deciding to purchase my Yaris. Once the Yaris was home and I was driving around, I verified that the very good fuel economy figures were true.

Pretty close with your new FR-S !

Yeah, not too far from the Yaris. Although I'm driving 5-10 mph slower and using premium gas now

[hans solo]

I got 42 mph on this last tank of gas.

[dj92]

Heavily loaded (rear wheel's upper ends began hiding behind/inside the fenders) some weeks ago including higher velocities (Autobahn): 6l/100km (300km trip) :D

[matti]

I'm about 2/3rds of the way through my current tank and I'm at 45.2 mpg. Starting in September I'll be doing a lot of freeway driving, so my mileage will drop quite a bit.

[timothyone]

If you stay around 60 mph. I drift between 60 and 65 and get well over 40 hwy. Anything over 65 will suck the gas. I enjoy cranking the music up and enjoying a nice cheap, safe drive. Only you know if you are actually have good reason to hurry.
