Prius economy sucks

The keywords "Camaro" and "sucks" pretty much said it all ...

 

No car using a petrol engine will get EPA mileage on a 6 mile commute. All petrol engines use additional fuel to warm up.
I have tried this before but it's a waste of key strokes because no one ever answers the question.
To anyone complaining about Prius economy is, what pecentage of EPA mileage did you actually get with the car your Prius replaced?
I bet it was similar to your Prius, you just never had a display to tell you about it.

 

yes i now

the economy sucks big time

i only get 1 liter to 20km at the moment

its because i am speeding rightnow when you drive the prius fast you get these bad figure's
normaly i get 1 liter to 23 km.











ok J/k of course

 

For example, my first winter with my Prius we had a brutal, "old fashioned" winter. Weeks of -40 C lows and -30 C highs, 15 minute commutes, constant use of electric rear defrost and Max Heat: 35 miles per Imperial gallon

Yeah, pretty bad.

My Prius replaced a 2000 GMC Sierra half ton truck with a 5.3 litre V8. Under similar conditions ... 6 miles per Imperial gallon

I've had people tell me right to my face that their similar vintage Chevy Silverado or GMC Sierra "always" gets 18 mpg under similar conditions. As I carefully keep track of fuel due to mixed business use, I know that to be a flat out lie

 

Lie is a bit harsh there Jayman, more likely they are ignorant rather than telling deliberate lies. If you don't want to know your real consumption because it's scary then it's better to quote EPA as actual consumption.

 

I've been considering your problem:

There is an answer but it is a little more involved than trying to install a supercharger or turbo:

• replace 1.5L with a larger engine, 1.8L should fit
• electric water pump
• electric AC compressor for your NHW11
• roller bearing, cam shafts
• adjustable intake valve timing
• adjustable exhaust valve timing
• run an exhaust bypass to a coolant heater core
• meter some cooled exhaust gas back to the intake
• replace transaxle drive chain with gears
• use dry-sump, transaxle lubrication
• increase the inverter voltage, power and battery cooling
• reduce both motor generators with faster spinning rotors
• add an engine rpm governor
• full length, under body, panels
• install low rolling resistance tires
• park in the shade in warm weather
• park in the sun in cold weather

Did I miss anything?

Most of these people aren't deliberately lying, but are simply deluding themselves. They remember the one best tank they ever had, round it up and fluff it up a bit, and then pretend they always get that sort of mileage.

I have a fried who claims he always gets 40+ mpg in his old Saturn. I'm sure it does fairly well - it is a small car with a small engine, and has a manual transmission - but there is no way he can consistently get that sort of mileage. This is also the same person who goes 9 knots in his sailboat when we are sailing right next to him doing 7. I think he has an optimistic eye.

Well, to my critical eye, it's borderline. As soon as I bring up "let's run a tank in your vehicle and I'll check the fuel economy" they IMMEDIATELY drop the topic

 

Anyone who owns a GM vehicle is likely to be in a state of denial. Its a defense mechanism. :madgrin:

 

Ah, denial, of course

"Denial ain't t just a river in Egypt," Mark Twain

"Denial ain't just a club outside of McMaynerberry," the King of the Hill episode when Dale Gribble's gay father comes out of the closet, he said that line suggesting that there is a gay gentlemans club in the neighboring town

Note: there really is NOT a river in Egypt named "Denial." It's a play on The Nile.

 

There is always a difference in vehicles & gas mileage, but it will typically run in a narrower range than the effects of the operator. You have, wind, hills, tire pressure, etc, etc.

I'm not a hypermiler, I would describe my style as a more gun & glide than anything else. I pretty much accelerate with the flow of traffic. If the traffic is sparce, I am a little more laid back. I try to drive smart.

Given that my very worst full tank was in the low 40's. New tires, wind, hills, cold, etc. My best tank(s) have been lower 60's, but I cannot maintain 60mpg + tank after tank.

I have way more highway than city & usually wind & definitely hills. A combination of the last three tanks is a 50.8 mpg over 1,400 miles. Given some of the unfavorable parameters, I think I may be in the top half of the normal drivers. I also run 195/60-15 tires which are appx. 1/2 " wider than stock & I did take a little hit on mpg with them & have 4,000 + miles on them & wouldn't trade the benefits for the mileage. But you can add probably a couple miles per gallon to my average with std tires.

If you are not getting good mileage, review all the reasons why & there is plently of info available on this forum. Once you have exhausted any potential problems, you might want to look at your driving environment & your driving style. You can try to work around any physical things that can be improved, ex routing.

I think the simplest way to "catch on" to driving your Prius is simply moniter your "instant mpg" screen. If what you are doing is improving the mpg it is good, if it lowers the mpg it is not so good. Like I said, you can't simply quit going up & down hills, but you can certainly experiment with what you are doing with your speed & "gas pedal" that increases or decreases you mileage.

The instigators that come here are just that & their expert "advice" is worth exactly what it costs.

Take away the green, etc, etc, etc. When I take the vehicle for what it does, how it does it, how it fits my needs & factor in the mileage = one sweet package. I'm 59 years old & it is the best vehicle I've ever owned & I am more satisfied with it than any vehicle I've owned. Everything else is gravy. Nice vehicle.

 

"My Car: Other Non-Hybrid"

TROLL !

 

Try pulling the floor mat from under the accelerator. I noticed an instant gain in power and throttle response. Right now I am looking at zero to 60 times starting in {D}“Drive” versus starting in {B}“Engine Brake”. When I pull away from a light in {B} the engine is already on versus in {D} so throttle response time is much quicker.

 

Lemme see if I've got this right...

A poster asks for tips on ways to increase "economy." :car:

A second poster responds to mash the go-pedal to the floor looking to
increase acceleration off the line.

Just what kind of "economy" are we talking about increasing here...
That of Saudi Arabia, Venezuela? :doh: :brick:

:noidea:
