The distance gains just keep on coming. In debuting its new X Hot drivers, Callaway Golf engineers say they have achieved gains of 13 yards as compared to their RAZR X Black drivers. These advancements are possible, they said, thanks to a host of design and engineering advancements that make the new drivers faster, hotter and more lightweight than their predecessors.
For the X Hot models, Callaway’s Speed Frame Face Technology increases ball speed, saves weight and optimizes stiffness and stress distribution across the face for more efficient energy transfer from the clubhead to the ball. The new face technology, which is also found in Callaway's RAZR Fit Xtreme driver, promotes more – and more consistent – distance, even on off-center impacts.
"With the X Hot Drivers, we pushed the Speed Frame Face's efficiency to a new standard, producing high ball speeds while maintaining the trajectory and accuracy that discerning golfers demand," said Callaway Senior Vice President of Research & Development Alan Hocknell. "The fast face on X Hot is one piece of the puzzle, though. We went to great lengths to configure the X Hot drivers not only to promote distance, but to progressively optimize performance for various player types."
By decoupling the face performance from the rest of the driver head, Callaway is able to boost ball speed without sacrificing optimum trajectory. And a tighter curvature face on the X Hot Driver (relative to the RAZR X Black) helps to provide more consistent sidespin and dispersion to promote accuracy.
In these new drivers, Callaway has implemented its thinnest casting technology ever in the all-titanium head to create a lighter swing weight and overall configuration, a combination that benefits most players in terms of head speed and distance, especially golfers with an average swing speed. Another benefit is Draw Bias Progression, which changes the amount of draw bias depending on the loft, allowing golfers to better control sidespin and tune their shot shape. Players with higher lofts can take advantage of higher draw bias for straighter shots, while players with lower lofts can utilize a more neutral Center of Gravity that fits their game.
Also featured in the X Hot Driver is the adjustable OptiFit Hosel, which adjusts the face angle in Open, Square or Closed positions to improve accuracy and trajectory, and allows golfers to dial in their preferred look at address. The X Hot Drivers also feature Project X Velocity shafts as the stock offering.
The 460cc standard model will be available in 9.5-, 10.5-, 11.5-degree models along with a 13-degree HT-model, and will feature a lighter overall club weight and a lower swing weight than the X Hot Pro model. The X Hot Pro model, which has a slightly smaller headshape at 440cc, will be available in 8.5-, 9.5- and 10.5-degree models and feature slightly more open face angles than the standard version.
The standard model will be available Jan. 25, 2013, while the Pro version will be available on Feb. 15. Both versions will carry a new product introduction price of $299.
Along with the new drivers, Callaway is rolling out a line of X Hot and X Hot Pro fairway woods. For these woods, Callaway engineered a Forged Speed Frame Face Cup made of high-strength Carpenter 455 stainless steel that is up to 40 percent thinner than last year's fairway wood face – and with a 90 percent larger sweet spot. As a result, Callaway says, the new woods produce significantly hotter responses all over the face.
The standard X Hot Fairway Woods will be available in a 3-Wood, 4-Wood, 5-Wood, 7-Wood, 9-Wood and 11-Wood, and will feature slightly longer shafts and more upright lie angles than the Pro models. The Pro clubs will be available in 13.5-, 15-, 17- and 19-degree models. Both versions will carry an introduction price of $229 per club.
