The first 110 MPG production vehicle

[hp2g]

HP2g is using by definition:

The U.S. liquid gallon is legally defined as 231 cubic inches,[1] and is equal to exactly 3.785 411 784 litres (1 L = 10−3 m3) or 0.133 680 555… cubic feet. This is the most common definition of a gallon in the United States. The U.S. fluid ounce is defined as 1/128 of a U.S. gallon.


British thermal unit (BTU or Btu) is a unit of energy used in the power, steam generation, heating and air conditioning industries. In scientific contexts the BTU has largely been replaced by the SI unit of energy, the joule (J), though it may be used as a measure of agricultural energy production (BTU/kg).

Note the title of this thread says MPG as does the website, not MPGe. It is being sold as MPG. Lets take a snapshot of it in case the jury wants to see it:

With respect to the automotive community,a gallon of fuel is more accurately defined by a unit mass at around say 6.215 pounds per gallon for gasoline,and an average heating value of around 18,400 Btus per gallon(gasoline).Mass is considered more accurate do to the thermal expansion/contraction characteristics of the fuel.------------- I believe the definition of a Btu,is the heat energy required to raise one pound of water,one degree F,from 60-degrees F.------------- The alternate fuels legislation which was passed in the 1980s allowed automakers to use a special fudge-factor in calculating fleet CAFE.If memory serves me correctly,a car which had 22 mpg fuel economy,using E-85 or M-85,would be granted a CAFE rating of 135-mpg for purposes of calculating fleet average.The allowance was for internal auditing purposes and never intended to suggest that a flex-fuel vehicle could possibly attain 135-mpg.It is my opinion that anyone claiming 110-mpg for an "engine-swap" borders on the absurd and would justify extraordinary proof.And as the fellow has said,"Sir,you have stolen my property,burned my home,and raped my wife,but be warned,you may go to far."

EPA CAFE

[edit] Calculation
Fleet fuel economy is calculated using a harmonic mean, not a simple arithmetic mean (average).[3] The harmonic mean is the reciprocal of the average of the reciprocals of the fuel economies of the vehicles in the fleet. For a fleet composed of four different kinds of vehicles A, B, C, and D, produced in numbers nA, nB, nC, nD with fuel economies fA, fB, fC, fD the CAFE would be:




For example, a fleet of 4 vehicles getting 15, 13, 17, and 100 mpg has a CAFE of slightly less than 19 mpg:





The harmonic mean captures the fuel economy of the fleet for driving each car in the fleet for 1 mile while the arithmetic mean captures the fuel economy of the fleet for driving each car until one gallon of gas is burned (i.e. the 13 MPG vehicle would be driven for 13 miles while the 100 MPG vehicle would be driven for 100 miles).

For the purposes of CAFE, a manufacturer's car output is divided into a domestic fleet (vehicles with more than 75 percent U.S., Canadian or post-the North American Free Trade Agreement (NAFTA) Mexican content) and a foreign fleet (everything else). Each of these fleets must separately meet the requirements. The two-fleet requirement was developed by the United Automobile Workers (UAW) as a means to ensure job creation in the US. The UAW successfully lobbied Congress to write this provision into the enabling legislation. The UAW continues to advocate this position.[18] The two fleet rule for light trucks was removed in 1996.

Fuel economy calculation for alternative fuel vehicles multiplies the actual fuel used by a "Fuel Content" Factor of 0.15[19] as an incentive to develop alternative fuel vehicles.[20] Dual-fuel vehicles, such as E85 capable models, are taken as the average of this alternative fuel rating and its gasoline rate. Thus a dual-fuel E85 capable vehicle which gets 15 mpg on E-85 and 25 mpg on gasoline would be rated as 20 mpg for CAFE purposes, in spite of the fact that less than one percent of the fuel used in E85 capable vehicles is actually E85.[9]

Manufacturers are also allowed to earn CAFE "credits" in any year they exceed CAFE requirements, which they may use to offset deficiencies in other years. CAFE credits can be applied to the three years previous or three years subsequent to the year in which they are earned. The reason for this requirement is so that manufacturers are penalized only for persistent failure to meet the requirements, not for transient noncompliance due to market conditions.

Hey doug, you remember that yellow fairlane wagon my dad sold you?

What does this have to do with anything? Spouting random facts won't increase credibility.

After you wade through the b***s*** you eventually find this:

Fuel economy calculation for alternative fuel vehicles multiplies the actual fuel used by a "Fuel Content Factor of 0.15

which when taken into account with their misleading crap, gives the expected fe, which is nothing special at all. Obviously they are banking on the fact that 98% of the people confronted with that steaming pantload aren't going to bother to really read it.

so if we whip out our trusty calc.exe:

110mpg x 0.15 = 16.5mpg that sounds more like a 400hp V8

That makes me think, E85 which means 15% gasoline = 0.15. So if you have a diesel and run B100 that means you get Infinity MPGe.
