That may not actually be true. EG:

Quote:
Honda's own life cycle analysis suggests that 78% of a Honda car's total CO2 output is produced during the driving of the vehicle. The remaining 22% is emitted during "production, resource procurement, transportation, service, and disposal".

While the quote refers to CO2 output, it's reasonable to assume that correlates to energy consumption.

Which is why it sometimes makes sense from a total energy efficiency perspective to ditch a guzzler for a more efficient new car (depending on how much of a guzzler it is).
