The goal of the XR16 driver ($349) design is to produce maximum speed through the swing with more forgiveness than the previous model.
With help of aerodynamics experts at Boeing the new shape of the crown creates approximately 30% less air resistance than the previous XR driver while the clubface creates 10% less, leading to more speed and more distance. A thinner clubface that's 9g lighter than the previous model also contributes to increased ballspeed while also enhancing MOI and forgiveness by allowing weight to be positioned lower and deeper in the clubhead.
Specifically these changes produce a CG that's 15% lower than in the previous XR driver and a 10% higher MOI. A Fujikura Speeder Evolution 565 shaft comes standard. The XR16 comes in 9-, 10.5, and 13.5-degree lofts.
The XR16 is also available in a Pro model ($399) in 9- and 10.5-degree lofts. The Pro features a slightly more compact 450cc clubhead and deeper face than the standard model as well as a more neutral CG bias. Though the Pro provides lower ballspeeds than the standard model it still features a low and deep CG for added forgiveness and stability. A Fujikura Evolution II TS 665 shaft comes standard.
To accompany the drivers Callaway is also introducing XR16 ($229) and XR16 Pro ($249) fairway woods. The standard XR16 fairway wood is available in 3+, 3, 4, 5, 7, 9, and 11 wood models and features a larger head shape than the previous model. A low CG and very high COR combine to provide not only added forgiveness but also longer distance. A thinner clubface and face cup provide a larger effective hitting area and even more ballspeed at impact while a more aerodynamic shape allows the clubhead to move through the air with less resistance.
The XR16 Pro fairway wood is available in 14-, 16-, and 18-degree lofts and features a more compact head shape for more advanced players looking for increased workability and shot shaping control.
All XR 16 models will be available at retail on 1/29/16.
