Callaway Epic Flash, Epic Flash Sub Zero are built with machine learning, artificial intelligence
With the Callaway Epic Flash Driver, the company builds on the very successful 2017 GBB Epic line. The Carlsbad-based company follows up the Epic-complementing Rogue with a driver whose story isn’t immediately visible upon a first glance at the club.
Flash Face technology is the centerpiece of the Callaway 2019 driver offering, and with it, beyond the usual distance-boosting claims, the company has done something truly interesting: leveraged artificial intelligence to create a golf club.

From an appearance standpoint, the inside of the titanium face features dozens of flowing ripples across the entire surface. While it may look like effects of a stone dropped into a pond or a topographic map, the structures actually work together to elevate the COR or the center of face. As expected, this yields increased ballspeed for longer drives.

Interior of Callaway’s Flash Face
Callaway leveraged A.I. and Machine Learning to cycle through 15,000 face architecture iterations, developing a more efficient structure with each one. For comparison, engineers typically do eight to 10 iterations of a new driver face.
“We couldn’t have come up with Flash Face using conventional engineering principles,” said Dr. Alan Hocknell, senior vice president of R&D. “We wouldn’t have gone in this direction without A.I. because it’s non-intuitive compared to previous face technologies, including our own VFT and X-Face. The wave configuration isn’t symmetrical, nor does the pattern seem logical. Yet the ripples work together in a complex manner to maximize ball speed. There’s never been anything like Flash Face before in golf equipment, and the effect on performance is intense.”
Callaway Epic Flash driver

Introduced in the original Epic driver of 2017, Jailbreak Technology is again a feature of Callaway’s driver offering this year.
To refresh, the technology positions two hourglass-shaped titanium bars parallel to one another behind the face. The ultimate effect of the technology is a more efficient face, which equals more ball speed, which equals more distance, according to the company.
Callaway also equips the Epic Flash with an MOI-boosting T2C triaxial carbon crown. As is the becoming an industry standard, the weight savings in the lightweight crown are redistributed in the body of the club. The triaxial carbon, which is-third the density of titanium, is twice as strong as previous iterations with a weight-saving tighter weave. The company has been using carbon composite technology since the 2011 Diablo Octane and Razr Hawk drivers.

Another feature of the 2017 GBB Epic, and one that wasn’t included in last year’s Rogue, adjustable perimeter weighting returns in the Epic Flash driver. You know the drill: the sliding 16-gram rearward weight is adjustable for a draw, fade, or neutral bias.

Callaway Epic Flash Sub Zero driver

With a 12-gram sliding weight on a track located at the back of the head, the Flash Sub Zero includes Adjustable Perimeter Weighting (APW) technology in a Sub Zero driver for the first time in this low-spin, high MOI offering.
In addition to the draw/fade adjustability afforded by the APW, the Epic Flash Sub Zero also features a weight embedded low and forward in the sole for CG lowering and spin reduction. The standard weight can be swapped out for lighter or heavier options via custom ordering.

“The Epic Flash Sub Zero driver is an extraordinary club,” said Gibbs. “Flash Face is a genuine ball speed innovation, and so is Jailbreak. Putting APW in a Sub Zero driver for the first time is a huge accomplishment. And it retains the rare combination of low spin and high MOI that have made our Sub Zero drivers so popular. We’re confident that a lot of golfers are going to hit longer drives than they ever have before with this club.”

Then and now: Comparing Rory McIlroy’s current setup to his record-breaking 2019 Canadian Open victory
In Rory McIlroy’s first appearance at the 2019 RBC Canadian Open, he crushed the record books to earn his 16th PGA Tour title in dominating fashion, winning by seven shots over Shane Lowry and Webb Simpson.
McIlroy’s score of 22-under-par 258 is the lowest 72-hole score to date at the Canadian Open, and his closing 61 is also the best final-round score in the history of one of golf’s oldest tournaments. Finally, with his win in 2019, McIlroy became only the sixth player to win the career Triple Crown, adding to his victories at the U.S. Open in 2011 and The Open Championship in 2014, joining Tommy Armour, Walter Hagen, Arnold Palmer, Lee Trevino and Tiger Woods in a coveted list.
So, with that, why not compare his current setup to the clubs he used to break all the records?
Driver
2019: TaylorMade M5 (9 degrees), Shaft: Mitsubishi Tensei CK Pro White 70 TX
2026: TaylorMade Qi4D (9 degrees @8), Shaft: Fujikura Ventus Black 7X (45 5/8 inches)

McIroy led the Tour in Strokes Gained: Off-the-Tee in 2019; he’s doing the same in 2026. Between now and then, McIlroy has switched from the Mitsubishi Tensei CK Pro White 70 TX (a shaft with slightly more feeling in the tip) to the original Fujikura Ventus Black 7X, having just made the change to the heavier version from playing the 60X.
What’s interesting about McIlroy’s 2019 setup is that the weighting on his driver is actually set in the high-draw setting, using the T-Track weighting system, whereas in the Qi4D, he’s currently using a heavily rear-weighted setup. (Two 13-gram weights in the rear and only two 4-gram front weights.)
The TaylorMade M5 driver he played in during his Canadian Open win was the company’s first head that they claimed to design to initially exceed the USGA’s COR limit, and then injected with tuning resin to bring it back in bounds.
Fairway woods
2019: TaylorMade M6 3-wood (15 degrees), Shaft: Mitsubishi Tensei CK Pro White 80 TX; TaylorMade M5 5-wood (19 degrees), Shaft: Mitsubishi Tensei CK Pro White 90 TX
2026: TaylorMade Qi4D 3-wood (15 degrees), Shaft: Fujikura Ventus Black 8X; TaylorMade Qi4D 5-wood (18 degrees), Shaft: Fujikura Ventus Black 9X

The TaylorMade M6 fairway wood that McIlroy was using during the 2019 season is still in the bag of some of the best golfers on Tour in 2026. Just check out Justin Rose’s winning setup from the Farmers Insurance Open earlier this year. This year, though, McIlroy has still been searching for his top-end-of-the-bag setup, having played both the new Qi4D and the Qi10, which he won the Masters with.

The same shaft swap can be seen in the fairway woods as the driver, along with slightly less loft on the 5-wood.
Irons
2019: TaylorMade P750 (4) Buy here, TaylorMade P730 (5-9), Shafts: Project X 7.0
2026: TaylorMade P760 (4), TaylorMade Rors Proto (5-9), Shafts: Project X 7.0

The biggest difference between McIlroy’s custom set and the stock P730s is the groove design. While the P730s were constructed with 14 MX-9 grooves on their milled faces, McIlroy’s proto heads instead use the higher-spinning, 16-groove layout of the TW2 grooves. Other big differences between the sets are that McIlroy’s 7- and 8-irons have thinner toplines, are 1 degree stronger in loft, and are 1/4 inch longer than the original P730 builds.
With McIlroy’s 4-iron, the switch from P750 to P760 sees a transition to a two-piece construction with Speed Foam in it, which allows McIlroy to launch the ball slightly higher, with more workability.
Wedges
2019: TaylorMade Milled Grind (48-09SB), TaylorMade MG Hi-Toe (52-09SB, 56-09SB, 60-LB09), Shafts: Project X Rifle 6.5
2026: TaylorMade MG5 (46-09SB, 50-09SB, 54-11SB, 60-08LB @61), Shafts: Project X 6.5 (46-54), Project X 6.5 Wedge (60)

Between 2019 and 2026, McIlroy’s focus on his short game has been much more apparent. It was the reason why he switched back to the TP5 golf ball, to help with launch, spin and control with his wedges leading up to his career Grand Slam victory in 2025. The most apparent changes to McIlroy’s wedge setup are his lofts and bounce. He’s slowly delofted his pitching to a sand wedge, but has increased the loft on the lob wedge, bending his current 60-degree to 61. With that, adding more loft to his lob wedge also slightly increases the bounce and leading-edge sit point, so, as a result, he plays a lower-bounce lob wedge compared to 2019. The MG5 wedges are also softer than the first Milled Grind option from 2019. McIlroy also no longer plays the full-face grooves found on the Hi-Toe.
Putter
2019: TaylorMade Spider X
2026: TaylorMade Spider Tour X

Notice anything similar. Yes, the copper finish on Rory McIlroy’s Spider X putter in 2019 is a slightly more reflective finish than the recently released torched PVD finish. McIlroy was using the True Path alignment system, but now uses only a single white sightline.
Ball
2019: 2019 TaylorMade TP5 (#22)
2026: 2025 TaylorMade TP5 (RORS)
As mentioned above, McIlroy had transitioned from the TP5 to TP5x golf ball since his victory in Canada in 2019, but now is black with the same style of golf ball as his victory at Hamilton Golf & Country Club.
Grips
2019: Golf Pride Tour Velvet Cord
2026: Golf Pride MCC
Interesting, McIlroy actually used Golf Pride’s Tour Velvet Cord grips during his victory in 2019 (it was during a 2+ year switch to the corded TV) as opposed to his usual MCC grips, which he has played for most of his career.

You people with your “go ahead and waste your money, gearheads” talk sound resentful because you frankly just can’t afford it. There is new tech in these drivers whether you want to believe it or not. I do agree that buying a new driver every year might not be necessary but I’m not knocking anyone that does.

Go to you tube and watch Rick Shiels videos. He has reviewed a lot of golf clubs. One of his videos compares several drivers, from the same brand to each other. In other words he compared the latest and greatest from a certain brand, and compares it to the older models from the same brand. He did that with a few popular brands. His take was that there wasn’t enough difference in the new clubs to make it worth upgrading. He actually found that some of the older versions were better than the newest. If you have money you want to throw away, or you get a boner having the newest clubs, by all means, buy away!

I can’t wait to see what the 2020 releases look like… Callaway states that their fancy “AI” came up with this as the face design. So that means you can never, ever switch face designs, right? This is apparently “the best”. Then Taylormade says now they’ve made their faces illegal but dialed them back with foam… what’s next? We’ve made our faces SUPER illegal and added MORE foam! This is all market BS at its finest…

How about moving up a couple tee’s….that will put short irons back in play….or just make courses shorter
How does one expect to grow the game when only the rich can play….. $550. drivers..
$4000. set of clubs at the bag drop…
$100. to $500. green fees…..and 5 hour rounds….
and I play for $2.00…front,back, 18..
Pretty funny when you think about it

Since most gearhead golfers lack intelligence, a dose of ‘artificial’ intelligence built into their golf clubs may be the solution to prevalent duffing and hacking. One can only hope. Great product Callaway.

Years of research and advanced technologies and this ugly mallet is what they came up with?
Green/Yellow = fail.
AI and ML generated ‘waves’? I can’t see this being legitimate as there’s too much dispersion between golfers to produce anything near as consistent as a computer generated test could perform. ‘for best results, hit the ball squarely and perfectly off this pin-sized dot at precisely at 120mph’.

I like the adjustable weighting, but if you have purchased a new driver in the last 4 years, any brand, don’t expect much more length and tighter dispersion. Modern drivers can’t get much closer to the USGA numbers for fear that some, during manufacturing, might exceed the max and become non-conforming. Before buying a new driver, compare your current model to the new model on the same monitor with the same balls. Don’t worry about spin or any numbers besides carry and your dispersion pattern. Anything less than 10 years with similar dispersion, put your money away!

MY driver is a 2007 TM SuperQuad. Took it to PGA Superstore last summer and hit it up against the TM M1 and Callaway Rogue. I gained 5 yards on average, with no better accuracy. I looked at the fitter and said I don’t think paying $500 for 5 yards is worth it. He nodded and said no its not.
I’ll keep testing that driver every year until something comes out that can give me real improvement. I bet I get 5-10 more years out of this one.

Jan 4, 2019 at 5:35 pm
Daniel you can probably get that 5 yards in your 2007 TM SuperQuad if you simply upgrade its shaft. That was a great head.

They have gone every 2 years just like Ping and Titleist. The original Epic came out in 2017. The Rogue was a different series or model. It’ll be replaced next year. Now Taylormade still goes every year.
