Both the crown and sole on the RAZR Hawk standard and Tour model drivers are comprised of the Forged Composite material (recall that material first appeared in the Diablo Octane driver), which is lighter, less dense, but stronger. It was developed in conjuction with automaker Lamborghini.
In a company news release, Dr. Alan Hocknell, Callaway's senior VP of research and development, said "the ability to precisely forge the carbon material to within one-thousandth of an inch yielded aerodynamic shaping that greatly reduced energy lost to drag during a golfer's downswing."
That surface shaping system is called Streamlined Surface Technology, and Callaway says it reduces drag in the downswing by 43-percent compared to the FT-9 driver.
The Callaway RAZR Hawk driver is available in Draw or Neutral models for the standard; the Tour version has a shorter shaft, slightly smaller head and more open face angle. Both the standard and Tour models will carry an MSRP of $399 when they hit retail shops on Feb. 18, 2011. callawaygolf.com
