70 MPG US (3.3 L/100 km) challenge (non-hybrid gasoline and diesel cars)

[slowmover]

Nice as a stunt.

Now, let’s load the vehicle according to design and see how things go.

The wusses can use the GVWR as limit, and the hairy-chested can use the axle/tire/wheel limits.

Ton Miles Per Gallon

as that’s a valid concept.

Shuffling an individual around bereft of gear or goods lacks meaning. Just “means” he does it with the air conditioning a motorcycle lacks. But he can’t account for unused capacity re empty seats and cargo space. IOW, it’s no test.

Make the test[s] real.

Vehicle scaled weight against published shipping weight (curb weight) for any test.

Loaded to limit, is the real FE test.

66-75% capacity for regular driving as the baseline.

I'm taking a 4x8 utility trailer full of crap down to southern Vermont tomorrow. I bet I still get significantlybetter economy than your truck, despite being loaded infinitely higher than the car is rated for.

It's a great idea ... let's create a category & run a competition. Seems to me Ecomodding trucks along the lines of Ton Miles Per Gallon would be brilliant.

That is a hair above 4l/100km. (4.035)

My car is rated for 3.7 l/100km highway.

Best i could do on the highway was 4.3.
Best tank 5l/100km

I should be able to get 70mpg on the highway. No way in the city (atleast my city)

Maybe I should have specified U.S. gallons. I think you may have miscalculated the US MPG's equivalent to liters per 100 km. I think 70 MPG (US) is equal to about 3.4 L/100 km. Are you maybe thinking of English gallons?

Nonetheless, if you want to make it 70 MPG in UK gallons because that's what you use, then go ahead. You still win the picture!

Slowmover, above, seems to be interested in a standardized test, and seems to think that that's the only serious test. But this is really just a challenge for individuals and not a test. An individualized instead of standardized challenge means that whatever your personal baseline has been becomes the legitimate context for determining success.

We use l/100km over here.

Taxi drivers and such use pennies/km. Which makes no sense as fuel is highly dependent on the USD and our pennies (kurus) varies a lot. So what you measure today is meaningless tomorrow.

On a road trip i just might be able to average that. But it will be hard, and very slow.

I wanted to try and see how well I could do on the trip from the grocery store (Walmart in Sutton, WV) to my apartment (in Glenville WV), but last time I hypermiled the route I only averaged 67.xxMPG... I checked tire pressure at the gas station next to Walmart, they all were really low, so I ran them up to 60psi (tires are wasted anyway and I really wanted to succeed, I normally do 55), and set off... I note the trip as three legs, Sutton to Heaters on WV-4, Heaters to Burnsville on WV-5, and Burnsville to Glenville on WV-5, for 28mi in total... I set personal bests on every leg of the trip and totally smashed my goal of 70mpg at the end...

Leg 1 ended at 99.5mpg avg
Leg 2 ended at 92.2mpg avg
Trip ended in Glenville at a total average of 77.4mpg!

Car was loaded with myself and GF, and a weeks worth of groceries so it kinda fit Slowmovers criteria of the car being loaded for the test lol

Wow! Absolutely amazing! You have officially CRUSHED anything I could've ever done in the Civic, even with it's smaller engine and whatnot! Heck, many Insight owners would be enthused to get that kind of mileage! Awesome job!

[19bonestock88]

Thanks man, really it’s just pulse and glide and reducing aero drag and rolling resistance wherever possible... engine size doesn’t seem to matter much?

70? Ha. Not with the amount of freeway I gotta do. Even when I had a special commute which would have been GREAT for this, I was high-50s. *sigh*
