According to Brian Goebel, the fuel improvement does not compromise anyway in terms of payload, horsepower and other specifications being the same as GMC and full size pickups.
Fuel efficient cars were introduced last year and have become very popular with consumers due to high rise of gas as much as $4/ gallon in United States last year.
The XFE (Extra fuel economy) label are now very popular and in high demand by car drivers. The trucks are rated at 15 mpg in the city and 21 mpg in the highway.
