How fast does a apache quad go?

The speed of an Apache quad, specifically the AH-64 Apache helicopter, can reach up to approximately 180 knots (around 207 miles per hour or 333 kilometers per hour) in level flight. However, if you're referring to an ATV (All-Terrain Vehicle) commonly known as a "quad," their speeds can vary significantly based on the model, but many can reach speeds between 40 to 70 miles per hour (64 to 113 kilometers per hour).
