Don't you just love that "new car smell?" At Toyota of Sunnyvale, we certainly did- until we found out what caused the scent. So, what exactly does cause the refreshing odor? Answer: a host of toxic chemicals that emit from the new materials used in new vehicles. Toyota drivers don't have to worry as much about this issue though, especially Toyota Prius drivers. The 2012 Prius lead this year's lineup of vehicles across the board as far as indoor air quality is concerned. And, because the average American spends more than an hour and a half in a car each day, good air quality is certainly something to be concerned about.
