A recent article in Off-Road reported on a road rally using brand new Jeep
Wagoneers with diesel engines.  One method of obtaining high points was to 
achieve the best mileage on the rally.  With the vehicle in 5th gear the
proper cruising engine RPM could only be reached by exceeding the 55 speed
limit.  I don't remember the exact figures, but it was somewhere around 63.
