I know you are asking yourself, why do you have two reviews of the same club, this being the Callaway Epic Driver and the Callaway Epic Sub Zero Driver. While they may look very similar and have many of the same characteristics, they are in fact totally different clubs.


See the all new Epic line has two models, the “standard” which is the Epic, and the Sub Zero, which was specifically designed for golfers who create a lot of spin. See low spin drivers have historically been smaller in volume, have a lower moment of inertia, and are fade biased. These types of clubs were specifically designed for low handicap players with a higher swing speed. The new Callaway Epic Sub Zero Driver breaks this trend and is different, by that it gives the player the best of both worlds. The Callaway Epic Sub Zero Driver incorporates both the Jailbreak and Exo-Cage technology found in the Epic Driver, which gives players more distance and speed, while moving the center of gravity on the club to the neutral line “hence the name Sub Zero”. By moving the center of gravity to the zero line, the Callaway Epic Sub Zero generates the same moment of inertia as the standard Epic but creates about 500 RPM less, thereby making it easier for amateur players to use the club.


Since it was first released in early 2017, the Cobra Sub Zero Driver has not only received the highest rating of Gold in the 2017 Golf Digest Hot list, but it has also become one of the most recognized clubs used on the tour. This mainly has to do with Callaway’s new Jailbreak Technology which solves the problem of the crown and sole separating as the club face is stretched vertically at impact. This separation results in a loss of energy transferring to the ball. So, does the Jailbreak Technology work, yes absolutely, and is why the Callaway Epic Sub Zero Driver is perfect for the mid to high handicap golfer looking to have better control of the ball, less spin, and overall improve their accuracy when on the tee box.

Key Features

The Callaway Epic Sub Zero Driver provides greater distance from its Jailbreak Technology. This innovative design changes how the club head behaves at impact, which helps to promote more speed across a larger area of the club face.

The Callaway Epic Sub Zero Driver provides maximum forgiveness, high launch, and low spin from the innovative combination of its titanium Exo Cage and triaxial carbon construction.

The Callaway Epic Sub Zero Driver does not have the same perimeter weighting system as the standard Epic model, rather it has two interchangeable weight that allow for spin rate adjustment up to 250-350 RPM less than the Epic driver.

Design and Technology

The Callaway Epic Sub Zero Driver combines the very best in technology and design. The marquee of the Callaway Epic Sub Zero Driver is its Jailbreak Technology. This technology is made up of the structure found behind the club face that is made up of two parallel titanium rods that connect the sole to the crown. These titanium rods help to stiffen the crown and sole, so they don’t flex as much at impact. It is this separation that results in a loss of energy that transfers to the ball. With this technology the Callaway Epic Sub Zero Driver can create more energy to the ball on impact that produces more distance and ball speed.

The Callaway Epic Sub Zero Driver also incorporates the impressive Exo Cage Construction. This construction allows for Callaway to integrate more carbon fiber into the design of the clubhead, which helps the Jailbreak Technology to really shine through.

Where the standard Callaway Epic Driver and the Sub Zero are vastly different is in its weight system. The Callaway Epic Sub Zero Driver does not have the same perimeter weighting track as the standard Epic model, rather it has two weight ports that exist in the front and back of the sole. Through the use of a 2 and 12 gram weight “screw” that comes standard with the Callaway Epic Sub Zero Driver, players can move the center of gravity of the club forward to reduce spin or rearward to improve consistency.


PROS

  • Impressive distance regardless of where you hit the ball on the club face
  • Sound at impact is much more muted than other drivers
  • Jailbreak Technology expands the sweet spot of the club and delivers high ball speeds

CONS

  • Some players might get overwhelmed with all the adjustability settings
  • Not much launch if you have a moderate swing speed
  • Some golfers may think that the club is a little light than what they are used to using

Our Experience

The Callaway Epic Sub Zero driver is a popular choice among golfers looking for a low-spinning driver that provides a penetrating ball flight. Several golfers have shared their positive experiences with this driver:


A golfer named Don helped fit a customer named William Beal for the Callaway Epic Sub Zero driver. After making some adjustments to his setup, Beal noticed a 10-12 yard increase in average distance and 50% more fairways hit compared to his previous driver. He also found the new driver more consistent in keeping his drives on the fairway.


Another golfer named Tanner Reed had great success with the Epic Sub Zero driver, taking 15 strokes off his game and making 5 all-conference teams after getting custom-fitted for the club.


A podcast host from the "No Laying Up" podcast also shared his experience with the Epic Sub Zero, saying he's "really enjoyed the ball flight" and the "lower spinning head" that the Sub Zero provides.


Overall, the Callaway Epic Sub Zero driver seems to be a reliable choice for golfers looking to optimize their tee shots with a low-spinning, high-launching driver that can provide extra distance and accuracy off the tee.
