While getting my truck inspected, I read an article in Mechanics Illustrated where they conducted a series of tests on Ford, Chevy, Toyota and Nissan pickups. I was surprised that the F150 came in last (The Nissan was first). in almost every test. The quarter mile time was really bad for the Ford, they ran empty and with 1000lbs aboard and the other 3 trucks with 1000lbs. beat the empty Ford. They attributed the bad results for Ford to the newer designs of the other 3 and said Ford will be playing catch up.
