You c guys need to step up your mpg game. ;)

Justify your poor mileage anyway you have to... most people won't ever be able to do 65mph average on a full tank of gas.

 

i've never seen the MPG goes lower than 47 to be honest. Even with eco off and driving like a hooligan, u might get less than 47MPg for a trip, but never for a tank.. tank average is always above 20KM/l without even trying.. But just for the record.. huhu, i'd love to see a 70MPG tank on my C

 

65 mph for 450 miles is as unrealistic as your "moving traffic pylon", where the C is concerned. Of course the car is more than capable of that kind of driving, but that's not the primary type of driving it was designed for. It's a "city car", for "around town" trips, and I'm guessing that's what the majority of people in the world (certainly Japan) buy it for. When I got my best tank of 80 mpg, that was moving with traffic, and not impeding anyone...because the car is best suited for Japan traffic patterns. To me, that makes your hypothetical 65/450 score of 3120 "positively worthless", and not just in appearance.

FWIW, on the expressway, averaging around 60 mph, I consistently show between 51 and 56 mpg. Not flat, lots of hills and turns. But that 450 miles would probably cost me $150 in tolls, so no thanks.

Unimpressed by people getting great mileage? Ummm...this is a Prius forum...move along.

 

My first few tanks were 43-50 mpg for January-March. Winters in Northeast Ohio are cold, windy and snowy/slushy. c does not like. Those were also my first three months, so some of that difference is not knowing how to milk the mpgs.

 

Luckily, we don't have winters here whole year long, coldest is perhaps 23C and it's always 30-32C all day long here.

 

Lucky!
My winters have highs in the 30s (F), 1-4 degrees C: Average Weather for Cleveland, OH - Temperature and Precipitation
And Lake Erie gives us lots of snow to plow through.

 

From my driveway in Uruma city to the town of Matsuda, back to my driveway, with a stop at the bank. 37 km/h average on a roadway that is all 40-50 km/h speed limit. Battery level the same at start/finish. Held up zero traffic, pulled over to let exactly two cars pass that wanted to go faster (I was going 60 in a 50), made no one miss any lights. 40.3 km/l (94.8 MPG) for 56.4 km round trip. Last time I did this exact route was in December and mileage was only 37.7 km/l (88.6 MPG). With no traffic, and no lights (after 12am), I'm wondering if I can break 100 mpg.

Now to go fuel up and repeat 15 times...LOL. Most people have no idea how hard this is. It takes intense concentration; situational awareness on a multilevel playing field. No way could I do it in one shot.

This is with no warm up cycle. The car was already to operating temperature. Tire pressure of 40 psi. 26C outside with 88% humidity, and 1010mb pressure. 12,000 km on the clock. Day to day average is around 28 km/l (65 MPG).

 

Good mpgs at high mph isn't that important to everyone, neither my commute to/from work nor my normal at work deliveries include any freeway at all. Only extraneous activities ever put me on the freeway, so good low speed mpgs are the most important ones to me...which is how I ended up with a C.

 

I drive the freeway every afternoon on my way home, for around 50 miles at 60 mph (some lights and ~5-6 miles of back roads to get on and off the highway). This usually yields a total trip mpg of around 62-63 with an average speed of 35-40 mph. You would either have to be hauling or taking a trip that is the entire tank to get your avg speed up.

 

Not only that, but deliberately wasting an entire tank of gas just to get high mpg numbers kinda goes against the whole point in saving gas by getting high mpgs.

 

Ok, 190km done on my fresh tank, 63MPG, and this is all 80% highway (thats my route to work). Tomorrow is off and i'll be scooting in urban area to do small chores. Surely will get better MPG. Don't worry, I'm doing 60-65mph (90-100kmh) on the highway, that is the lowest reasonable speed over here.

 

I read the definition of "Hypermiling"... hahaha, I am already hypermiling!!!

 

click on fuelly signature... that's what i usally refer people to when they ask about my mileage.. lol.

the car is currently over 34k miles but i haven't had to fill up yet.. but so far as you can see.. over the lifetime of owning the vehicle.. i've been keeping my all-time average pretty high i'd say... especially considering most of my miles are highway. (granted a decent portion of that is during traffic hours... so.. I wouldn't be traveling that fast anyway.. LOL.)

 

More than that, good mpg at high mph is arbitrary to driving conditions and, once your foot is stable enough, completely independent of skill. Given the same driving conditions, equal tire infation and a plateaued skill level, any difference in mpg would be "my car got built better than yours." Driving on the freeway is pretty straightforward. You want to get great mpg at 65 mph, find the power needed and don't move your foot. In those specific driving conditions, the mpg you get is the mpg you get- there's nothing else to be done.

 

I use cruise control but slow down when going up a hill/based on traffic conditions. Of course, I also only go 55-62 based on traffic. My c has encouraged me to take back roads more often, since I can squeeze more mpgs out of it that way. It takes a bit longer, but it's far more interesting and fun.

 

Which is why I haven't added my name to the list...yet. With an average daily-driving tank being 28.5 km/l (67 MPG), I could step firmly into 16th place. I guarantee you that the top ten didn't get that # with a long trip on the highway, short daily commutes with multiple warm up cycles, etc...

But what about "fun"? Not everyone who buys a hybrid does so just to save gas; there are other aspects.

With a little over 1,000 wheel horse power and a BSFC of 0.55, my old Nissan Skyline GT-R would burn about 7 liters of gasoline per minute, at full boogie. This was acceptable because it was "fun". I've competed in drag racing, gymkhana, rally, motocross/enduro, shifter carts, etc, because it was fun. I built and tuned race cars for a living because it was fun.

Toyota took a Gen II to the salt flats to see how fast it would go. Could we say: "Toyota isn't interested in "saving gas"?

Your remark is a blanket statement, covering a wide spectrum, where perspective plays a huge part.

I reached a point where my hobbies were too expensive, so I decided to stick to what I love (outdoor activities like camping, hiking, sea kayaking, surfing, spearfishing, etc), and cut out the motorsports 99%. Even on the business end. Went full time into standard automotive repair.

We bought our Toyota hybrids for several reasons. At the time of purchase for each car, it was time for a new car. Gas in Japan is expensive, so a hybrid makes sense for a daily driver. The price was comparable to an equally-equipped Toyota of the same grade. We work on Toyota and Honda hybrids so it looks good when we drive them, believe in the technology, and they give us a learning platform to work with; hands on. Guess how much gas we've wasted studying and mapping the HSD system relationships. I am more (way more) interested in the technological aspect of the hybrid, than saving gas.

You know what? It also turns out they're fun to drive. It's a lot like a rally, and takes skill to generate high MPG numbers. It's very much like any other motor sport, only without the speed.

So back to "perspective". You could say I'm not "saving gas" by burning 30 liters to see how high a number I can get. I say compare burning the occasional tank in the C to a weekend of racing the GT-R.

How about now? Am I saving gas now? Still having fun on the technical side of driving a car, and saving gas at the same time.

What if I make a video showing other Toyota hybrid drivers how I did it? If I could help others to save fuel, would that be worth the tank of gas?

Driving for the fun of it... Not everyone who buys a hybrid believes that cars are evil, and that any drop of fuel not used in the pursuit of "necessity", is wasted.

Cheers.

 

You do got a point there Matt I waste precious fuel on the Track every now and then, but on a bike haha, my bike is fuel efficient though if you compare the HP it makes vs the fuel it burns, but for daily use, my Prius C uses less fuel than my bike my bike does only 25MPG haha.

 

I got into hybrid because of the tech.. same reason why i got into the C as honda's hybrids to me is just a car with an electric motor bolted on to it.. the Prius is far more advance. I wanted to hypermile because of the competition I found it similar to racing, its all about technique and I want to master it and win hahaha and seeing others do over 60MPG on a tank is like seeing another rider doing a faster lap time. Been watching lotsa tutorial vids, I'll break that 65MPG soon huhuhu.

 

Never said that there aren't other types of people that have cause to use whole tanks of gas at a time. I, in fact, deliberately avoided (deleted even) mentioning other types of people in my post to avoid becoming too verbose, there was no malicious intent to make a blanket statement about all Prius owners.

 

Did a 66.5mpg for this tank. 24mph avg.
