what is the optimal speed for an automatic car (ford focus)?
Is there a chart of speed vs. fuel consumption (e.g., if I drive 10% faster than the optimum - how much more fuel will be cunsumed?)
 
The best spped taking into account economy is 56MPH. to acheive this you may be revving the engine more or keep dropping off the accelerator to do this so you woue to have some sort of cruise controlv ha

The lowest speed that it will stay in top gear with the torque converter locked up on cruise control. Probably around 55 mph.
