On the original Fujita scale a 75 mph wind would be in the F1 range, However, it is in the EF0 range on the Enhanced Fujita scale.
EF stands for Enhanced Fujita scale, which is used to classify tornado intensity based on the damage caused. EF2 on the scale indicates a tornado with estimated wind speeds of 111-135 mph that can cause considerable damage.
The highest Fujita rating for a tornado is F5, which represents winds of 261-318 mph (419-512 km/h). F5 tornadoes are considered to be the most powerful and destructive, capable of causing catastrophic damage.
Sort of. On the original Fujita scale theoretical categories F6 to F12 were plotted, but they are never used, as ratings are based on damaged, and an F5 tornado leaves nothing left to destroy. Since it was never used, the Enhanced Fujita (EF) scale did away with it completely, giving any tornado with estimated winds over 200 mph a rating of EF5.
No tornado has ever been stronger than F5. Fujita scale ratings are based on damage and F5 damage damage is total destruction. This makes it impossible to assign a higher rating.
There is very little difference. In February of 2007 the Fujita or "F" scale was replaced with the Enhanced Fujita or "EF" scale. The EF scale uses more detailed analysis of damage than the original F scale so that tornadoes can be rated more accurately. The EF scale also provides different estimates of wind speeds for the degrees of damage. So EF1 damage is essentially the same as F1 damage but it may be examined in greater detail. Additionally F1 wind estimates range from 73 mph to 112 mph while EF1 wind estimates range from 86 mph to 110 mph.
The highest rating for a tornado is EF5 on the Enhanced Fujita scale or F5 in the original Fujita Scale. Winds in these tornadoes can exceed 300 mph.
A tornado with peak estimated winds of 100 mph would be rated F1 on the Fujita scale.

On the original Fujita scale and F1 tornado has estimated winds of 72 to 112 mph. This was adjusted to 86 to 110 mph on the Enhanced Fujita scale.

On the original Fujita scale a 200 mph wind would correspond to a strong F3 tornado. However, the wind estimates of the original scale have been found to be too high (actual ratings are based on damage severity). Now, on the more accurate Enhanced Fujita Scale 200 mph would be a borderline EF4-EF5 tornado.
The Enhanced Fujita scale puts the beginning of tornado winds at 65 mph. Doppler radar has detected winds in a tornado of just over 300 mph.
The Pampa, Texas tornado of June 8, 1995 was an F4 on the Fujita scale.
On the Ehnahnced Fujita scale, 200 mph is a borderline EF4/EF5 tornado.
