A riddle: Why has the Toyota Prius enjoyed such success, with sales of more than 400,000 in the United States, when most other hybrid models struggle to find buyers?
One answer may be that U.
S. buyers of the Prius want everyone to know that they are driving hybrids.
The Prius, after all, was built from the ground up as a hybrid, and is sold only as a hybrid. By contrast, the main way to tell that a Honda Civic, Ford Escape or Saturn Vue is a hybrid version is a small badge on the trunk or side panel.
