Driving on the road one can easily spot a Toyota Prius, but since other automakers including Toyota have come out with different hybrid models, its pretty difficult differentiating between a similar hybrid from its conventional counterpart. I keep looking for that little energy sign on the back of the cars. So in an effort to bump up other hybrid model sales, Toyota plans on making these hybrid asthetically different from there gas counterparts. So, when consumers go to buy a hybrid, such as the Highlander for example, they want the rest of the world to know they are driving a hybrid. All I can think of at this moment is a green metallic sign in the shape of a leaf on centre of the tire hub caps. Anybody else got some ideas.
