How are these people on Fuelly getting such bad MPG's???

Well this was a fun read. Thanks. Obviously it wasn’t an AWD but this is helping me feel a little better.

I would think the AWD would only affect mileage when it’s activated, right? AWD motor is only a fraction of the weight of the cargo they loaded that Limited with. Plus the Limited FWD has 19 inch tires too.

 

Depending on the type of motor Toyota used at the rear, there could be additional drag caused by it.

 

That was a really poor attempt at getting bad mileage in a Prius. Anyone that's been around PC for a number of years remembers Jeremy Clarkson showing you could get as poor as 17MPG with very little effort.

Disregarding Clarkson is an ignorant tool - the folks at torque couldn't even get into the 30s? Wow - talk about delegitimizing their abilities .....

Clarkson has always hated the Prius. His antics (besides the video above) have been stunts like shooting a 50 cal machine gun into a Prius. Despite his poor motives - he does show that you can kill any car's mileage either due to environment, or driving patterns, or a deliberate stunt.

Long gentle city driving with minimal friction braking and mostly regenerative braking will also result in excellent fuel economy for Prius, as the aerodynamic drag is minimal.

 

I get 75 mpg on my Gen 4 Prius Prime on the freeway in the HEV mode, but I mostly drive 57-mph.

 

Here is another short "tutorial" on how to get low mpg with the new P5 (in every day driving):

 

Nope, real mpg. Gen 4 Prius Prime is a very fuel-efficient car. Arguably, the larger traction battery helps better optimize the HEV driving as well.

 

The poor folks that find it inexplicable how some folks might get only get 35 MPG over an entire tank of gas .... are probably the same poor folks finding it inexplicable how others can get 75 MPG over an entire tank of gas.



Somehow it escapes folks that when you average those highs & lows together you get an average that's pretty close to the EPA's estimate. Thus - YMMV

.

 

My all-time real HEV mpg (after discounting BEV driving and MFD overestimation) is around 70 mpg, well above the EPA's 54 mpg. This was verified by manual calculations.

It depends on how you drive the car. If you are a hypermiler and drive a little slower, Prius is capable of 70–80 mpg.

Moreover, my average MFD mpge is around 6.3 mi/kWh (× 33.705 kWh/ge = 212 mpge)—perhaps comes down to around 5.7 mi/kWh (192 mpge) at the plug—well above EPA's 3.95 mi/kWh (133 mpge) at the plug.

 

Thank you for never missing a chance to say how great your car is - mileage wise - especially when compared to the 2023 - 2024. It certainly never gets old.
Even in threads about very poor mileage - it gets slipped in as a major thrust. Yes! your car is certainty better than the best! Maybe - if we all had a dollar for every time we continually get reminded of this "better" factor of your older car - we could drive our inferior plugin hybrids for thousands of miles - to take up the difference of your cars greatnes!
Thank you ! (whew)

It is the best car ever.

 

I just crossed paths with someone who has one of those huge 2023 RAV 4 Primes. Since she received the notice to not plug it in when it’s cold out due to possible fire risk she has been driving it as a hybrid and gets 40mpg. If she can do this in that big box, a 2023/24 Prius should be able to regularly get close to 50mpg I would hope.

 

None of the above.

 

This is the guy pissing everyone off on the on-ramp.

 

Wow, this mpg thread is almost as fun as an oil thread

That being said, all the thumping about how good one's mpg is, is just smokescreen unless you can back it up with data on an ongoing basis. The only mpg that matters is tracking how many miles you drive on a tank of gas. FIll it up, do the math, log it and repeat. That's why I use an app. I originally started using it to track the general overall health of my vehicles since deteriorating mpg can be a sign of mechanical issues. It also paints a picture of how well the vehicle operates under different conditions like when the seasons change, using different tire pressures or different set of tires or different grades of gas etc.

And for anyone who says they can only get 35 mpg in a Prius yet drives like a Grandma, they haven't seen the way my 89 year old mother drives.
