Gott made his comments back in 2001, and believed that hybrids "were going to be the panacea." Because reports began to show that hybrids got, on average, 20 to 30 percent lower mileage than EPA estimates, U.S. consumers realized that their gas savings would not be as high as they once expected, even though they were still 25 to 30 percent more efficient than their gasoline counterparts.
Gott now believes that diesels will be the fuel efficient choice of most automakers in the next decade. He predicts that sales of diesel-powered vehicles will reach 12 percent of the U.S. market by 2026.
