The X Hot driver incorporates some of Callaway's well-known technology, such as Speed Frame Face Technology, to address not just efficient energy transfer from club to ball, but also weight savings.
The thin, all-titanium head helps create a lighter swingweight and lighter overall clubweight, while the clubface has a tighter curvature to create a look preferred by better players at address.
Something new from Callaway is the X Hot Driver's "Draw Bias Progression." What that means is that as the driver loft increases, so does the draw bias: more draw bias in higher lofts, less in lower lofts.
The stock shaft is the Project X Velocity. The Standard Callaway X Hot Driver comes in lofts of 9.5, 10.5, 11.5 and 13 degrees, with a 460cc, matte-grey clubhead. The MSRP is $299, with retail availability beginning on Jan. 25, 2013.
A Pro model will also be offered, beginning on Feb. 15, 2013. The Pro Callaway X Hot driver has a slightly smaller clubhead (440cc), more open face angles relative to the Standard model, and lofts of 8.5, 9.5 and 10.5 degrees. It, too, will have an MSRP of $299. callawaygolf.com
