As a GM fan, I appreciate the fuel mileage I get out of my 2000 suburban 5.3 with 200,000 miles. This engine will not beat the ecoboost is 0-60, but does the job towing our tt very well. I am sure that the fuel mileage of my 13 year old truck can beat the new high tech ecoboost. Wonder if the new 5.3 direct injected will give me even better that my old truck ??
