FIAT comes to north America

Never claimed my math was worth a doodally.

The is only one way to determine fuel efficiency that is when you use less fuel to move the exact same vehicle or weight.

a 1000LB car gets 15MPG

The same exact 1000LB is "monkeyed" with and now gets 22MPG. It is now more fuel efficient.

A 770LB car that gets 22MPG is not as efficient as the 1000LB car.

When ever we launched a bird we had to determine the cost, in fuel, PER POUND of payload.

If I remember correctly the new fuel standards for trucks being imposed on our industry is based on this idea and NOT on MPG.

MPG in itself is not a true measure of fuel efficiency. It is only a measure of MPG.

I'm still waiting for the explanation. Something that makes sense.

At 10mpg, it isn't the weight that is being moved that matters, it is the effeicency of the engine and how much fuel is used. Comparibly speaking, if you have 2000 lbs of freight on your truck and a van driver has the identical amount of freight but he is getting 18 mpg while you are getting 11, who uses less fuel?

By the way Specific Fuel Consumption is used to measure engine efficiency.

IF I remember correctly BTU's is what we used to determine how much fuel it took to move a given weight.

The fewer BTU's per pound the more efficient. When I asked the engineers at JPL this question they agreed. Same when I dealt with Morton Thiokol and LockheedMartin. They always determined efficiency comparing apples to apples.

It was always about using less fuel to move x amount of pounds. Therefor a more efficient engine/launch vehicle. Always tested with the exact same expected payload weight.

It should make no difference if it is a rolling or flying vehicle.

What am I missing?

Greg,

All Joe is saying is that if you measure efficiency based on the pounds per gallon of gas used, per mile, as opposed to the standard straight miles per gallon figures, his Freightliner is more efficient than most personal vehicles. If his truck moves 3,000lbs per gallon of fuel burned, it is by that measure more efficient than an econobox car like the Ford Fiesta, as mentioned in Post# 20 of this thread which only moves 65lbs per gallon of fuel burned.

If the average car buyer had a need to move 3,000 lbs on a regular basis, the difference would matter.

Last I checked, this thread didn't pertain to the needs of "average car buyers".

GVW is what matters. Many passenger cars weigh in excess of 2000lbs. When I used my truck as an example I used empty weight.

If you want to use loaded weights my freightliner looks even better.

It is clear why some people ask for spreadsheets so they can figure their MPG.

Yes, GVWR makes the comparison all the more starker. Since passenger cars aren't designed for heavy payloads, GVW is more of an apples to apples comparison.

Im still learning my 3's and 4's.

saw one on the ohip tp last week. or was it the week before? anyway gracie looked at it and declared it cute then read the usatoday review and declared it ..."not for us". course not it isn't a tdi.

LOS and camper,
Apples and oranges here.

My sprinter is more fuel efficient per pound per mile than my VW Jetta TDI.

So, I need to go shopping, or on vacation to Florida for a week. Should I drive the Sprinter which gets 26 MPG, or my Jetta which gets 50 MPG?

Which vehicle will save me money for the whole trip? The sprinter which is more fuel efficient per pound per mile, or the Jetta which is less efficient per pound per mile?

I can guarantee you that the Jetta will be better in this scenario.

Is the same point I was making: the most efficient vehicle is the correct one for the job it's doing.

As long as you will not use you Jetta TDI to try and pass Elephants on the right in your way to Florida...

Moose, that's a CLASSIC, lol. [And I'll never try to pass an elephant, even in the truck!]

actually fiat has been here, represented by others, for quite a while.
seen a ferrari? fiat.
seen any j.i.case farm or const equipment? fiat.
