San Francisco Chronicle-10/22/06 "...Congress capped the hybrid incentive at 60,000 vehicles per manufacturer, an arbitrary limit that -- due largely to the success of the Prius -- Toyota passed in half a year.' "By essentially functioning only as a limit for Toyota, the cap reduces Detroit's competition, removing incentive for the Big Three to change. So when Toyota's credit is phased out, a Chevrolet Silverado hybrid averaging 18 miles per gallon will receive a $650 incentive, while the 55 mile-per-gallon Prius will get none." http://www.sfgate.com/cgi-bin/article.cgi?...EDGMQKEJ2V1.DTL
