Other difficulties
We have to consider difficulties when evaluating the
below PHEV performances without bias:
- Fuel Efficiency Estimation
It is very difficult because PHEV is two kinds of
energy supplied from external sources, not only
petroleum. How does it differ from conventional
vehicles which use only petroleum energy from
external sources?
- Reflection of actual utilization
PHEV performance especially fuel economy and
emission are drastically change by driving range.
Representative values have to reflect the actual
