Nike Golf has announced that the square-headed SQ Machspeed driver will be in pro shops in March, 2010. But company representatives say Justin Leonard doesn't want to wait that long and might put the driver in his bag next week at Harding Park Golf Course during the Presidents Cup.The company says a system it developed called Total Swing Aerodynamics helps the Machspeed increase a player's clubhead speed and add yards to tee shots. Tom Stites, Nike Golf's director of product innovation, said in a release: "The number one thing that makes the ball go farther is faster ball speed. We've accomplished that through looking at the orientation of aerodynamics throughout the total golf swing, not just a portion of the swing."Stites compares a club swinging toward a ball to a parachute. "The wider the parachute is, the slower it comes down because air separates around the parachute and causes drag. The same thing applies to the golf club."By rounding certain areas of the clubhead and designing it to allow air to move more smoothly across it, Nike says the square head of the Machspeed actually has reduced drag.For shot-shaping flexibility, Nike equipped the Machspeed with the adjustable STR8-Fit system introduced last year in the SQ Dymo drivers. Using an included torque wrench, golfers can unscrew the head and reattach it in one of eight different settings to change the face angle, loft and lie angle of the club. The Nike Machspeed driver will retail for about $360.
