Could the proposed relaxation of car mileage standards prolong the life of V8, in particular the Hemi engine? The EPA has proposed freezing mileage standards at the 2020 level, when vehicles will be required to hit an average of 30 miles per gallon. Previously, the fleet mileage standard was supposed to increase to an average of 54.5 mpg. by 2026. This would increase the price on a new car by over $2,100 and probably spell the end of gas guzzling V8 engines. In response, seventeen states sued the EPA, in May, from scrapping the 2026 standards. In addition, about a dozen states, such as CA and NJ, want to set heir own higher mileage standards to improve air quality. This battle between the states and the federal government should be interesting to watch, especially its impact on owners with high performance V8s.
