Callaway to release Sub Zero driver, with the company’s lowest CG ever
The chase for a lower center of gravity (CG) has taken Callaway below the neutral axis line with its new XR 16 Sub Zero driver. According to Callaway, the driver is made for better players with fast swing speeds, and boasts the lowest CG of any Callaway driver ever designed.
Imagine the neutral axis line as a line drawn backward, perpendicular from the center of the club face, as illustrated above. While most drivers have a CG above that line, the XR 16 Sub Zero, which measures 440 cubic centimeters, boasts a CG below it.
The XR 16 Sub Zero was lower spinning than Callaway’s Big Bertha Alpha 816 DBD driver in the company’s robot and player testing.
Drivers with low-CG positions can help golfers lower their spin rates, allowing those with fast swing speeds to achieve a more penetrating trajectory that can increase distance. The most notable example is Phil Mickelson, who is currently using the Sub Zero driver on the PGA Tour.

To achieve the Sub Zero’s lower CG, Callaway gave it a new crown, which is made of a “Carbon Triax” material. According to Callaway Senior R&D manager Evan Gibbs, the new crown is made from “fabric, or laminate,” which is different from the chopped fibers that are used to make the carbon fiber crowns for Callaway Great Big Bertha and Big Bertha Alpha 816 DBD drivers.
All three drivers use the same molding technique for their crowns, however, the Carbon Triax material is thinner and lighter, allowing weight to be displaced lower and deeper in the club head.
Compared to Callaway’s XR 16 and XR 16 Pro drivers, the XR 16 Sub Zero will not have as high of a moment of inertia (MOI), a measure of ball speed retention or forgiveness on off-center hits, due to the concentration of weight low and forward in the club head. That’s not ideal for golfers who struggle to make consistent contact, but skilled golfers can use the lower CG position to hit longer drives.
The XR 16 Sub Zero is also adjustable, allowing players to fine-tune their trajectory with a 10-gram and 2-gram interchangeable weights that are placed in opposing weight ports. Moving the heavier weight forward makes for a penetrating, lower-spinning trajectory, while moving it rearward setting will provide a higher launch and more forgiveness, but slightly raise spin in comparison.
Callaway’s XR 16 Sub Zero driver (9.5 degress, RH Only) will be available for $449.99 on April 15 with the choice of 20 premium shaft at no upcharge.

Uhhh, Cobra King LTD beat them to the market with the zero CG driver. Plus, the Cobra LTD has nice forgiveness unlike what Cally is claiming is lost with the Subzero. LTD for the win!

“bro i hit it like 20* 1000rpm 380 yds.”
one release later: “not forgiving enough.”
another release later: “20* 1000rpm seems about right”

If Phil is hitting it, what no lefty for the rest of us? What’s up with that?

I don’t see the big deal. Ping has a low spin driver as part of the G series this just looks like a low spin XR 16.

To all you nay sayers. I have been buying every new driver that has come out from callaway and taylormade and have really embraced the new technology. My average drives are between 680 and 700 yards and golf has become very easy for me.

Finally they made a perfect driver until the next one. Just a joke. No wonder equipment makers are struggling. They flood the market, more supply then demand. Why would anyone buy at full retail from cally, tmag when in a few months it is on the clearance shelves.

Another driver that people on WRX will go crazy about because it is low spin but nobody will be able to hit. Like the Slider 430
