Oh yeah, well a diesel hybrid is way more efficient, but the oil companies won't acknowledge that...and to think, they used to pump the components of gasoline back into the ground because they were undesireable by-products...
BTW the price of diesel in my area has stayed fairly constant for the last 4-5 weeks while gasoline prices have rocket, the local farmers just laugh at everyone driving a gas powered rig...!
Have you seen the size of the tires on the Prius. They look like they were taken off a tricycle. I wouldn't want to go around a turn too fast or they would come off the wheels.
If the electric portion of the hybrid is flexible enough to completely control the engine RPM by controlling the load, you could even use the dual-fuel diesel. Which, the book said 50 years ago, might be the most efficient practical thermodynamic cycle.It consists of a diesel engine with a lean carburator, which requires a pilot charge of diesel to ignite the main charge of gas. Runs smoother than the diesel, but can't be throttled and must be controlled by main force through its torque loading.
Do you mean bio-diesel hybrid?
