Three-Quarter-Ton
SRW Crew Cab Short-Bed 4x4 Gas Pickups
There
was a side benefit that came from testing the three-quarter-ton trucks
on the level surface at MPG. Using Ford's two-mile long straightaway,
we were able to capture speed and times up to 90-mph, even though the
distance required to hit this mark took over a quarter-mile. You'll
see this extra data in the bar graphs and tables below.
