Our basic automobile drive train high efficiency premise for a 3000# car is to use:
- an 80-100hp electric primary motor/generator
- a smaller 30-40hp gas engine running at a constant RPM while engaged to the road
- power stroke phasing pulse technology
- an efficient infinitely variable speed drive (IVSD) transmission
A current 3000# car (Honda Civic, Ford Fusion, and Dodge Omni) uses an average of 25 horsepower (15hp for constant 55mph on level ground) for everyday driving, and returns around 35mpg highway. So at 55mph, and driving for an hour that’s 1.6 gallons of gas. The energy in 1.6 gallons of gas is around 196,000 btu’s or 80 horsepower. So the fuel consumed equates to 80hp, but the engine only produced about 16hp for an hour from the 1.6 gallons. That is around 20% efficiency. That equates to 6.3cc/hp/min (6.3cc of gasoline per horsepower per minute). The remaining majority of power is lost primarily to heat through the exhaust and the radiator.
Our company goal is 100 MPG highway at 55mph in a 3000# car, not some 1000# streamlined missile on a test track or hypermiling at a reduced speed, but a real 100 MPG at 55mph in a real car.
These potential changes in fuel consumption can be accomplished through power train innovations, basic rolling resistance changes, and/or aerodynamic changes. It would require a fuel consumption drop from 6.3cc/hp/min to 2.37cc/hp/min or 2.9cc/hp/min at a steady 55mph, and we are currently at 3.9.
