disappointing EPA MPG numbers?

With some of the numbers I'm seeing in city driving (or slower commuting), I might just stay off the interstates altogether. ;D

 

the ERA is more like average MPG. some people can get only 47MPG combine on prius and some other can get 55MPG. lol

I read couple reports and the average MPG on the Prius C is about 50 -55 combine. it get less on highway speed. it is easy to get 55MPG on city driving.

 

It is very difficult to make a short car aerodynamic. The highway mileage suffers because at highway speeds you are moving a lot of air around.

 

My Jeep is very short and it...oh. Never mind.

Maybe you can modify and make the c and the Jeep more aerodynamic... like Inspector Clouseau's Silver Hornet below!

 

I only put 125 miles on my odometer, but I definitely get better than 46mpg on the fwy (on the screen anyways). High 50s low 60s is more like it, and im a newb. I haven't filled up yet, so I don't know how accurate it is. Though someone here did say that the prius c computer is almost dead on compared to the regular Prius.

 

Nice. What's your average highway speed?

EDIT: I saw your other post. Nevermind...again, impressive.

 

yeah same here have to wait and see how accurate the MID is, I keep driving between lexington and Georgetown and get high 60's low 70's over 15 to 20 miles. Highway after a good distance I can get in the 50's on flat freeway, hills appear to be dropping me closer to 49 to 50 after about 55+ miles.

 

I think the city could be better but they had to keep costs low. I assume that with higher performing batteries and/or hybrid power train they could grab a lot more juice back from braking and increase mileage.

If you look at it another way, though, the second gen Prius came out 8 years ago and the mileage has not improved much since then. There definitely appears to be a bit of a ceiling following the initial gains of the technology that will not move quickly. Mileage I expect to keep creeping up, but unless we're willing to pay a great deal more for advanced tech, no more huge gains. I guess the 4th gen Prius would be something like 53/49 or 53/50 vs the current 51/48

 

I suspect that when Toyota is designing these things they probably look at a balance between cost of the vehicle and fuel economy. Lets say they could have a Prius that gets 60 mpg, but costs one or two thousand more to manufacturer, they would have to decide which is going to be more profitable. Will the extra 8% efficiency be enough to entice customers to buy, despite the increase in cost?

 

So, lets say you take a 2012 new Prius, a regular Prius, and
reduce its weight by 500 lbs to a curb weight of say 2,600 lbs

I would think the official MPG from EPA would probably read 55 city 50 hwy, I know it could be done with carbon fiber etc. but would be way too expensive.

I must say that our Prius, even with a gross weight of 3,850 lbs,
weighed on Oregon State Truck Scale, delivered 54 mpg calculated
on our trip last year, all three of us, from Seaside to San Francisco and back. Took I-5 down and the coast hwy back.

I wonder with the same cargo weight what the Prius C would deliver
for MPG on an identical trip in the summer.
