jOkeass was the fraud.
I read another article about Tesla not meeting expectations.
Frankly, this could kill Tesla.
“Fuel economy” is one of those things that changes depending on who is doing the computations. Convert into something like “fuel cost per mile” and the virtues of gasoline at $2.50/gallon versus $5.00/gallon. Same number of miles travel per gallon, but at twice the cost per mile.
Rationing by price does create an incentive to make internal-combustion engines more fuel efficient, but because so much of the energy is converted to heat instead of actually supplying power to the traction wheels, such gains are fractional at best, and might not be applicable under all circumstances.
Go a step beyond internal combustion engines, and consider the possibilities of an EXTERNAL-combustion engine, by heating some fluid medium up to expansion, and using the heated fluid medium to drive either a turbine or a reciprocating piston with a crankshaft and flywheel, and rotational energy may be used to propel the traction wheels.
Two designs exist, generally, one driven by heated air (the Stirling engine), or one that relies on converting water to steam, and using the heated steam to either spin a turbine or a reciprocating piston design, and collecting and recycling the spent steam by condensation. The heated air system has the advantage of not requiring the condensation of the spent medium and recycling. Both of these design schemes were worked out well over a century ago, and some got pretty sophisticated, considering the technology of the times.
The Doble steam-powered car was perhaps the most highly developed of the external-combustion engines. Jay Leno has done a lot of work with these steam-powered vehicles.

Virtually all of the CAFE and emissions standards mandated by the EPA were driven by one source: CARB, the california air resources board.
The EPA had their heads so far up CARBs ass, it wasn’t even funny. Up until the early 90’s, the automakers made two versions of every vehicle offered for sale in the US, either federal (49 states), or california.
It was so bad, that at one point, GM was seriously considering stopping sales to california, and if they did, the others would have followed suit. They were losing money on every california emmisions equipped vehicle.
And to add insult to injury, all of that emmisions equipment and tuning actually ruined their CAFE ratings.
This is why cars and trucks built in the late 80’s and early 90’s had better mileage than most of the current comparisons.
