Boeing helps Callaway design aerodynamically-sound XR16 drivers
In the current driver market, golf equipment companies have a tall task — make drivers that are even longer and more forgiving than the ones currently available. Making things more challenging is that two very important factors in driver design, aerodynamics and forgiveness, have a somewhat inverse relationship; a longer crown improves forgiveness, but it is also generally less aerodynamically sound.
The major issue is that as a driver head moves through space, air wants to leave the crown as it passes over the face. That increases drag and decreases club head speed, a bad thing for distance. For Callaway, solving this problem meant working with aerodynamics experts at Boeing — the world’s largest aerospace company, which designs and engineers jets, spacecrafts and planes for NASA and the U.S. Air Force.

So the people who typically design wings to help airplanes fly through the sky were assigned the task of helping design golf clubs that make golf balls fly farther. The result was Callaway’s new XR16 and XR16 Pro drivers.
The new crown design on Callaway’s XR16 drivers features raised portions of titanium just behind the top line that help keep airflow tight to the surface, thus reducing drag and allowing golfers to swing the club head faster on the downswing into impact.
The aerodynamic improvements also allowed Callaway to stretch out the crown of the XR16 drivers, raising moment of inertia (MOI), a measure of a club’s forgiveness. The combination makes the XR16 drivers faster and more forgiving.
Changes inside the head include improvement to Callaway’s R-Moto technology, which debuted in Callaway’s Big Bertha Alpha 815 drivers. R-Moto is a supportive rib structure that allowed engineers to make the XR16 driver faces 9 grams lighter and 19 percent thinner than their predecessors. The result is more ball speed, regardless of where shots are contacted on the face, along with better launch conditions.
Another weight-saving tactic from Callaway was implementing a lighter, 8-1-1 Titanium body. It offered 2 more grams of discretionary weight compared to the original XR drivers, and while that doesn’t sound like a lot it can make the difference between flying a fairway bunker and being plugged in its lip.
Callaway XR16 Driver
Compared to the XR16 Pro driver, the XR16 has a bigger, deeper footprint for more forgiveness. The 460cc driver comes stock with a Fujikura Speeder Evolution 565 shaft, and several other premium shafts are available at no upcharge.
- In stores: January 29
- Lofts: 9, 10.5 and 13.5 HT options
- Price: $349.99
Callaway XR16 Pro Driver
The XR16 Pro is designed for better golfers. It’s lower spinning than the XR16, creating a more penetrating trajectory because of its lower CG and deeper-faced, 450cc club head. It comes stock with a Fujikura Evolution II TS 665 shaft, but several other premium shafts are available at no upcharge.
- Comes to retail: January 29
- Lofts: 9 and 10.5 degrees
- Price: $399.99

Spotted: Luke Donald’s new Odyssey Versa 12 CS putter
Luke Donald has been using a center-shafted Odyssey #7 putter for a very, very long time. Recently Luke decided that he wanted to change it up and try some new putters, according to Joe Toulon, Callaway’s PGA Tour manager.
The new putter is an Odyssey Versa Twelve CS mallet, center-shafted, of course. Odyssey’s Versa high contrast alignment system debuted in 2013 and brought back this year with a full line of head shapes. The Twelve CS is a high MOI mallet with a raised center section and “wings” on the sides. The head is finished in black and then a large white rectangle runs down the center of the putter to aid in aligning the putter towards the target. There is also a short site line on the top, right next to where the shaft attached to the head.
Odyssey’s famous White Hot insert is a two-part urethane formula that offers a soft feel and consistent distance control. The sole features two weights that are interchangeable to dial in the desired head weight and feel. The Versa Twelve CS usually comes with Odyssey’s Stroke Lab counterbalanced graphite shaft but Luke looks to have gone with a traditional steel shaft and a Super Stroke Claw 2.0 Zenergy grip in Red and White.
Our own Andrew Tursky asked Joe Toulon about the type of player who gravitates towards a center-shafted putter:
“Since it’s easy to manipulate the face angle with something center shafted, probably someone with good hands. If you’re a good chipper you may like the face control that a center shafted putter offers.”

7 takeaways from an AWESOME equipment talk with Padraig Harrington
Fans of golf equipment have long known that Padraig Harrington is one of us. Throughout his career, Harrington has been willing to test new products, make changes from week to week, and play with a bag of mixed equipment brands.
What equipment fans may not know, however, is just how brilliant of an equipment mind Harrington truly has.
Ahead of the 2023 Valero Texas Open, I caught up with Harrington to pick his brain about what clubs are currently in his bag, and why. The conversation turned into Harrington discussing topics such as the broader equipment landscape, brand deals in 2023, his driver testing process, why he still uses a TaylorMade ZTP wedge from 2008, square grooves vs. V-grooves, and using a knockoff set of Ping Eye 1 irons as a junior.
Padraig Harrington’s 2023 WITB
Below are my 7 major takeaways from the extensive gear talk with Harrington.
1) Padraig’s stance on equipment contracts, and why he prefers Wilson
Harrington is a longtime Wilson staffer, and although he supports the brand and uses their equipment, he doesn’t use a full bag of Wilson clubs. He finds Wilson’s understanding of a player’s need for flexibility to be beneficial to the player, and it’s attracting more and more professional players to the company (such as Kevin Kisner and Trey Mullinax).
“Wilson wants me to play whatever I’m comfortable with. It’s very important. They’re not a manufacturer that says, ‘We want you to play 14 clubs.’ There’s always a club you don’t like. That’s just the way it is. So Wilson is like, ‘We want you playing well and playing the best clubs for you.’
“I am very comfortable with their irons. I’m very comfortable with their wedges, as you can see. They have an old hybrid 4 iron that I love. They have a new hybrid 4-iron that is too powerful. I put it in the bag last week and I had to take it out. The thing is, I use a 4-iron and a 5-wood. My 4-iron has to go somewhat relative to my 5-iron, and then I have to bridge that gap between 4-iron and 5-wood, so it has to do both. The new 4-iron was going 230 yards. My 4-iron goes about 215-235, maybe 240 on a warm day. And my 5-wood is like a warm-day 265 in the air, but I have no problem hitting it 235, so I can cross it over. But this 4-iron, the new version, it just went. I couldn’t hit the 215 shot with it; it’s just too powerful. That’s why I have the old 4-iron in the bag, but it does the job to bridge the gap…
“As players get more money, they’re less dependent on manufacturers. They need the service of a manufacturer – because, like I need to be on that truck and get things checked. But you’re seeing more players see Wilson as an attractive option because you don’t have to use 14 clubs. If you’re not happy this week with the putter; you know, Wilson has the putters, they have everything, but if you want to chase something else for a moment…remember, there’s two things you’re chasing. If you’re a free agent, it’s not good to be changing a lot. That is a distraction. But it’s nice to have the option that if somebody…like I feel Titleist has come out with a great driver. And I’m able to work my way straight into Titleist and say, ‘Hey, gimmie a go with that. Oh, this is a great driver, I’m going to use this.’ Wilson is aware of that. They want their players to be happy and playing well. Like it’s still 10 clubs, but it’s just not 14 and the ball.
“The irons are great, there’s no doubt about that. They’ve won the most majors. They make a gambit of irons. If you want to use a blade, they have the blade. If you want to use my iron, which is just a good tour composite, it has a bit of a cavity-back, you can do that. If you want to use the D irons that have rockets going off there, you can have them. Like the 4 iron, the one they gave me, it was a rocket! And guys are happy to carry driving irons like that, but mine has to match in with the 5-iron. It was just too high and too fast.
“So yeah, I think you’re going to see manufacturers go more of that way. Our players want to be independent, but the problem is that full independence is not great. You don’t want a situation where you’re turning up – as you see kids who make it into their first tournament, and the manufacturers start giving them stuff, and they’re changing. You don’t want to be the guy changing too much.”
2) The dangers of a 64-degree wedge
Although Harrington himself uses a Wilson Staff High Toe 64-degree wedge, he seldom practices with it. Here’s why he warns against it:
“The big key with a 64 wedge is DO NOT use it. No, seriously, do not use it. It’s a terrible wedge for your technique. That club is in the bag and it gets used on the golf course, and it gets used when it’s needed, but you don’t practice with it, because it’s awful. So much loft will get you leading too much, and you’re going to deloft it. Hit one or two shots with it, then put it away. You’re better off practicing with a pitching wedge and adding loft to be a good chipper instead of practicing with a lob wedge and taking loft off. A 64-degree wedge is accentuating that problem. It’s a dangerous club. It does a great job at times, but it certainly can do harm.
“It’s not bad having it in the bag for a certain shot, but it’s a terrible club to practice with. I literally hit one or two full shots with it, a couple chips with it, and that’s it. I know if I spend too long with it, I’ll start de-lofting.”
3) The interchangeable faces on TaylorMade’s ZTP wedges from 2008 were Padraig’s idea?!
I couldn’t believe it myself, but Harrington says that the idea for TaylorMade to offer interchangeable face technology on its ZTP wedges in 2008 was originally his idea…
“The TaylorMade is obviously attracting a lot of attention, but that was my idea! Myself and a consultant for Wilson, I got him to build changeable faces and he sold that to TaylorMade…that’s fully my idea. He sold that then to TaylorMade, and TaylorMade produced them, which I was happy about. But TaylorMade couldn’t sell them. You can’t get people to clean the grooves, so they weren’t going to buy a new face. Why have 400 faces at home? So I went out and bought these faces to make sure I had them for life. And I was home chipping a while ago, and I have a nice 58. I like the grind on that wedge, and the fact I can just replace the face and have a fresh face every three weeks, it’s just easy, so that’s why that’s in there.”
4) Driver testing isn’t all about speed
“The driver companies know I’m a free agent when it comes to drivers, so every time a new driver comes out, they’ll come to me and say, ‘Hey, would you have a look at this?’
“I will test everything, yeah, but it has to beat what I have in the bag. And Wilson’s new driver is the same. They brought out a new driver and it’s great, but I love the driver I’m using. So I say, ‘Look, guys, not only do you have to be as good as the incumbent, you have to be better, because I already know this and I’m familiar with it.’
“Wilson has built a very, very good driver. There’s know doubt about it. But I love the driver I’m using. And none of these manufacturers can build me a driver that’s better.
“Ball speed gets a driver into the conversation, and then you bring it to the golf course. So the driver has to be going as good as my current driver, and then I bring it to the course and see if I can hit the thing straight. I have gone down the road [of prioritizing speed]…I used a driver in 2014, and it never worked weekends. But it was fast. I used it for about six weeks I’d say – six tournaments – and I missed six straight cuts. It never worked the weekend. It was really fast on the range, but it just wasn’t good on the course.”

5) Playing with knockoff irons as a junior
“I played as a junior for Ireland, under 18’s, and I owned half a set of golf clubs, and they were imitation Ping Eye 1’s. I borrowed the other half set off my brother. We had a half set each. I had the evens, he had the odds. In that tournament, there was a guy playing with Ping Berylliums with graphite shafts. They cost 1,900 pounds. Mine cost 100 pounds, and they were knockoffs. So I played, for my country, with a set of knockoffs. Before I used those knockoff clubs, I used a mixed bag of clubs. As in, I picked up whatever club they had. The 6-iron might go farther than the 5-iron. The 5-iron might go with a fade and the 7-iron might go with a hook, but I knew what my clubs did. Each club had a purpose.”
6) Using square grooves and V-grooves simultaneously
Square grooves – or “box grooves” – were outlawed by the USGA in 2010 because they were said to help golfers spin the ball too much. V grooves are said to provide less of an advantage because they restrict the sharp edges of the grooves, thus reducing the amount of friction imparted on the golf ball. Prior to the rule change, however, Harrington actually used both V grooves and box grooves, and he’d adjust his setup depending on the golf course.
“What’s interesting is, when the box grooves were around – very few people know this – I carried two sets of clubs at all times. I carried a V groove and a box groove.
“Yeah, see, the box grooves were unbelievable out of the rough, spin wise, but if the rough got to a certain level, the ball would come out so low and with spin that it wouldn’t go very far. Your 7-iron coming out of this rough would only go like 140 yards and it wouldn’t get over any trees because it would come out so low. What I was doing was, if I got to a golf course with this sort of a rough, I’d put in a box groove 7-iron and a V-groove 8-iron. If I got in the rough and I had 170 yards, I’d hit an 8 iron and get a flyer, because the 7 iron wouldn’t get there depending on the lie. And I couldn’t get it over things. So if there were trees, you needed the V groove to get over the trees. A box groove wouldn’t get up in the air.
“No one else was doing it. I played with the box groove for a couple years before I realized that in certain rough, you need the V groove to get there. Hale Irwin played a U.S. Open seemingly with no grooves. Off the fairway it’s meant to make no difference. I would disagree, but that’s what the officials would say. But out of the rough you needed the flyers to get to the green. The V grooves were doing that for me. You get your flyer to get of the rough to get the ball there, but then if it was the first cut of rough, or light rough, or Bermuda rough, or chip shots, it would come out so low and spinny that you’d have no problem.
“I can’t believe that people didn’t realize that I was doing this two-groove thing all the time. I swear to you, you could stand here, you would not launch a 7-iron over that fence there if it was box grooves out of light rough, and V groove would launch over it. The launch characteristics were massively different.”
7) Blame the person, not the putter
Interestingly, Harrington, for all his tinkering, has only used a handful of putters. It turns out, there’s a good reason for that — although he’d like his current model to be a few millimeters taller.
“I used a 2-ball when it came out. Then I used a 2-ball blade, which I won my majors with. I always had a hook in my putts, so not long after I won my majors, I went to face-balanced putter because it helps reduce the left-to-right spin. I started putting really badly in 2013 and 2014 – I had some issues. And then come 2016-2017, I just said, look, I putted well with this putter. If I use this putter, I can’t go back and say it’s the putter’s problem. It’s gotta be me. So I went back to the face-balanced 2-ball blade because I’ve had good times with it. I may have only used 5 or 6 putters in my career.
“I’m really happy that I’ve got a putter that I know I’ve putted well with, and I don’t blame the putter. I can’t say that anymore. I don’t blame my tools, I blame myself if I miss a putt. So it comes down to…I know the putter works, then it’s me. Me, me, me.
“You know, I’ve toyed with using other shafts in the putter, and I will look at other putters, but things are askew to me when I look down. So I can’t have a putter with a line on it. It doesn’t look square to the face. I’ve never putted with a putter that has a line on it for that reason. I line up by feel. I know that putter works, I know it suits me, so that’s why I go with that…
“I prefer a deeper putter (a taller face). The one issue I have is I hit the ball too high on the face, but they won’t remodel the whole system to make me a deeper putter. I’ve tried some optical illusions to try and get it where I hit the ball more in the center, but I hit it high. It seems to be going in the hole so I’m not going to worry about it too much. But in an ideal world, if someone came along and said they could make the putter 3-4 millimeters higher, I’d be happy with that.”

TaylorMade survey on ball rollback finds everyday golfers massively against introduction of Model Local Rule
In response to the USGA and R&A’s recent announcement that they plan on rolling back the golf ball for the professional game, TaylorMade Golf issued a survey asking everyday golfers to voice their opinion regarding the topic of golf ball bifurcation. Today, they are sharing the results.
Almost 45,000 golfers across more than 100 countries spanning a variety of ages, abilities and participation levels took the time to complete the survey and have their voice heard, with some of the major findings shown below:
- To the best of your knowledge, do you agree with the proposed golf ball rule?
- 81% No
- 19% Yes
- Do you think average hitting distances in professional golf need to be reduced?
- 77% No
- 23% Yes
- Are you for or against bifurcation in the game of golf (i.e., different rule(s) for professional golfers versus amateurs)?
- 81% Against
- 19% For
- How important is it for you to play with the same equipment professional golfers use?
- 48% Extremely important
- 35% Moderately important
- 17% Not important
- If the proposed golf ball rule were to go into effect, would it have an impact on your interest in professional golf?
- 45% Less interested
- 49% No impact
- 6% More Interested
The results also show that 57 percent of golfers aged 18-34 years old would be less interested in the pro game should the rule come into effect, while five percent said they would be more interested.
“The goal of our survey was to give golfers the opportunity to voice their opinion on this proposed ruling as we absorb the MLR and its potential effects on the everyday golfer. We are grateful that nearly 45,000 golfers across the world felt the need for their voice to be heard. The overwhelming amount of responses show the passion, knowledge and care for the game our audience possesses. Each response and data point is being reviewed as we will utilize this feedback in our preparation to provide a response to the USGA and R&A.” – David Abeles, TaylorMade Golf President & CEO

Dont try to confuse me with facts – it is fun to buy new clubs. Its like a second marriage, a triump of hope over experience!
Jan 8, 2016 at 4:06 am
Had a 10.5 tour issue pro driver in hand last night. It look and sat amazing. Didnt get a chance to hit it however the Pro who had it was loving it.
Jan 7, 2016 at 4:45 pm
Total farse. How many yards can you gain if you don’t hit center due to aerodynamic improvements? ZERO. Even if you do hit dead center at 115mph ss, can callaway empirically prove an increase in yardage vs. this same driver with these turbulators? What would that number be? 1 yard? 5?
Jan 7, 2016 at 10:35 pm
The Farce is strong with that one
Jan 7, 2016 at 1:28 pm
Ah Callaway…another attempt to recycle technology with a fancy big name to operate as best supporting actor.
Remember the Ruger Titanium?
Remember the Lamborghini carbon fiber?
Now the Boeing ‘turbulators’?
Jan 6, 2016 at 5:06 pm
so callaway went to an aerospace company and found out turbulators help with club head speed, but ping found this out completely in house and a couple years ago. wonder which company is more revolutionary…
Jan 7, 2016 at 8:42 am
But can say it was developed by experts at Boeing? These guys make planes, PLANES! How dare compare it to a Ping.
Jan 6, 2016 at 3:52 pm
To be fair, I own an x2 hot pro after the xhot. Can’t hit anything better than that, tried the XR, big Bertha etc, I actually bought one as a spare!!
Everyone finds THE driver that suits then eventually. don’t agree that these drivers outplay predecessors by 10 yards, only people find a head and a shaft that suit the swing more, due to readily available custom fitting?!!
Jan 6, 2016 at 12:15 pm
Looks like a Ping, hits like a Ping, sounds like a Ping
Jan 6, 2016 at 12:07 pm
I have a prototype driver head designed by an iconic long driver who has passed. The head is F-17 aerodynamic and makes the new XR look like a Model T in comparison. Would love to show it to Taylormade or Callaway but from what I’ve heard they would probably steal the design and leave me high and dry.
Jan 6, 2016 at 10:05 am
So does this mean we’re officially done with the whole sliding weights bs they’ve been pushing for the last couple of years?
Jan 7, 2016 at 3:51 am
Different model entirely.
Jan 7, 2016 at 12:27 pm
I can see that it’s an entirely different model. Thus my question. If the sliding weights thing is so damn good, why didn’t the designers integrate sliding weights into into this model too? Or does that come later after they’ve convinced a lot of people to buy this model?
All these tech ‘advancements’ just make it more clear than ever, companies have hit a wall with current technology. Maybe PXG found something new recently, but has anyone actually seen their scores improve because they switched to the newest and latest driver? Also, have you actually tracked the distance of every drive to know you’re getting something more than you were before?
Jan 7, 2016 at 10:39 pm
Different model entirely. One line for adjustable weights, the other with a simpler set up.
For me, when I all of a sudden hit over a bunker I used to go into on a regular basis with the same swing same tee box same ball within the last 3 to 4 years in the same condition at the course, then yes I’m definitely getting something more.
Jan 6, 2016 at 8:36 am
This is it the final piece to my perfect golf swing. I was always telling everyone that my drivers werent aerodynamically enough and I was right. This driver is the break through I have been looking for. It has raised pieces that reduce drag, this is awesome. Should I buy this one or wait for the one with wings to be released? These guys keep raising the bar everytime.
Jan 6, 2016 at 10:25 am
haha. nicely done.
Jan 6, 2016 at 12:11 am
Tell that boy to ease up
Jan 5, 2016 at 9:59 pm
I had a Vega DAF (Dual Air Flow) driver yeears before the other major OEMs thought about aerodynamics..Vega bought the airflow patents from Makser, the real pioneers of modern aerodynamic driver design. Remember many of my buddies teased me about the Vega claims, now they talk themselves blue about turbulators etc etc

Callaway making some great stuff in the past 3-4 years.
Love the looks and styling of all of their clubs lately.
Jan 5, 2016 at 3:14 pm
What’s that good for? Maybe .25 mph at 100mph clubhead speed for about half a yard?
Anywho keep em coming!!! More drivers to buy for $150 at the end of the product cycle. 🙂
Jan 5, 2016 at 2:26 pm
I played 4 drivers last year (M1, ALPHA, G30, D13) and they all had different characteristics, shafts and science behind them. Every time i switched i would hit the new driver long and straight. After a few weeks i was hitting it just like the old driver. Not sure i buy into all this science but i love tinkering even though i see very little benefit in the long term. My golfing buddy plays a 2009 Cleveland with very little science incorporated to its design and he hits it longer and straighter than any driver i have played. We both play to a 13 handicap with swing speeds around 106 mph.
Jan 7, 2016 at 3:53 am
Totally useless non-technical post, but do go on
Jan 5, 2016 at 1:53 pm
“It offered 2 more grams of discretionary weight compared to the original XR drivers, and while that doesn’t sound like a lot it can make the difference between flying a fairway bunker and being plugged in its lip.”
Sorry but no, 2 grams won’t make that kind of difference. Sorry but 2 paper clips worth of weight just can’t cause that much change.
Jan 7, 2016 at 3:53 am
Actually, it does.
Jan 5, 2016 at 1:45 pm
Callawaybulators!! Welcome to da party pal! I can’t imagine how much pressure the modern day club designer must be under.
Jan 5, 2016 at 5:59 pm
Isn’t that “Callabulators”?
Jan 5, 2016 at 1:09 pm
Callaway, the new TaylorMade.
Jan 5, 2016 at 5:58 pm
It’s once per year. Last year, same time, the XR Series made its debut replacing the X2Hot.
Jan 5, 2016 at 12:18 pm
I spy Turbulators…
Jan 5, 2016 at 11:29 am
A new driver from Callaway, I’m shock I tell you!!!
Jan 5, 2016 at 11:18 am
Great. Three months later, they will release another driver with design aided from Aliens on Mars
Jan 5, 2016 at 7:13 pm
Next drivers are due in late August if the trend remains…
Jan 6, 2016 at 11:09 am
I agree ! Seems Callaway, and Taylormade. are both on a ” New driver every 6 months ” cycle.
Jan 5, 2016 at 10:57 am
Will the increased lift help top the ball better?
Jan 5, 2016 at 9:59 am
And I thought the XR Drivers of 2015 were too light! Wow. At least they got rid of the Project X shaft. Not a fan. The Fuji is a better shaft.
